Background: Cardiogenic shock secondary to acute myocardial infarction (AMI-CS) is associated with high mortality despite advances in therapy. The intra-aortic balloon pump (IABP) is used to support hemodynamics in these patients, but its efficacy remains debated. This study aimed to evaluate the outcomes of IABP use in patients with AMI complicated by CS. Results: This retrospective cohort study included 95 patients with AMI-CS treated at a tertiary referral center from January 2020 to December 2022. Patients were divided into two groups: those receiving IABP (n = 72) and those not receiving IABP (n = 23). Baseline characteristics revealed that patients who received IABP had more advanced shock [SCAI stage E 25% vs. 9%, P < 0.01], an increased prevalence of cardiac arrest at presentation [31% vs. 4%, P = 0.01], and required more aggressive hospital interventions, including vasopressor support [97% vs. 39%, P < 0.01], mechanical ventilation [90% vs. 30%, P < 0.01], and renal replacement therapy [42% vs. 9%, P < 0.01]. The IABP group had significantly higher in-hospital mortality [69% vs. 30%, P < 0.01]. IABP was associated with increased in-hospital mortality in patients with cardiac arrest [OR 27, P < 0.01], but in patients without cardiac arrest, IABP use reduced mortality [OR 0.15, P = 0.02]. There were no significant differences in cerebrovascular accident, bleeding, and length of stay between groups. No significant differences in long-term survival were observed between the groups [log-rank P = 0.44]. Conclusions: IABP use in AMI-CS patients was associated with higher in-hospital mortality, reflected by the more critical clinical status of these patients at baseline. IABP may offer in-hospital survival benefits in patients without cardiac arrest but does not improve long-term outcomes. Further research is needed to refine its role in clinical practice.

Introduction: In patients with acute myocardial infarction and cardiogenic shock (AMICS), the intra-aortic balloon pump (IABP) remains the most commonly used form of mechanical circulatory support. However, information on the characteristics of nonresponders is limited. This study evaluated the risk factors associated with 30-day mortality in a cohort of patients with AMICS, on IABP support. Methods: The medical records of patients admitted for AMICS, who underwent IABP insertion over a period of 5 years, were extracted from the electronic database of a tertiary cardiovascular disease center. The primary endpoint was 30-day all-cause mortality. Results: A cohort of 62 patients was included in the analysis. Mechanical complications were diagnosed in 54.8% of the patients. At 30-day follow-up, mortality reached 69.3%. High arterial lactate at the time of IABP insertion (OR: 1.04; 95% CI: 1.01–1.09; p = 0.04), high arterial lactate after 24 h of circulatory support (OR: 1.07; 95% CI: 1.02–1.17; p = 0.03), and low lactate clearance at 24 h (OR: 0.51; 95% CI: 0.22–0.83; p = 0.03) were associated with 30-day mortality independent of infarct type, mechanical complications, baseline SCAI stage, creatinine, and bicarbonate value at the time of support initiation. Lactate at the time of IABP insertion and lactate at 24 h predicted 30-day mortality at a cutoff value >50 mg/dL and >27 mg/dL, respectively. Conclusion: In a cohort of patients with AMICS who underwent IABP therapy, dynamic arterial lactate values both pre- and post-IABP insertion were independently associated with increased 30-day all-cause mortality. The dynamic changes in arterial lactate could help establish the optimal timing of circulatory support initiation and guide treatment escalation in patients at risk for adverse outcomes.

Abstract Background The use of intraaortic balloon pump (IABP) effectively reduces left ventricular afterload and significantly increases coronary perfusion pressure by raising aortic diastolic pressure. This study examined the short and medium-term outcomes of 22,540 adult cardiac surgical patients requiring an IABP. Methods From 2009 to 2018, 1114 patients (4.94%) undergoing open-heart surgery at a single tertiary cardiac hospital received IABP support and were included in this retrospective study. They were categorized into pre-operative (Group A, n = 577), intra-operative (Group B, n = 475), and post-operative (Group C, n = 62) IABP insertion groups. Results Cardiogenic shock occurred in 11.2% of cases, mainly in Group A. Hemodynamic instability (38.8%) drove IABP use in Groups A and C, while difficulty weaning from CPB was the primary reason in Group C. The overall operative mortality rate was 10.9%, highest at 25.8% postoperatively. Multivariate analysis identified significant predictors of mortality: age (OR: 1.067, 95% CI: 1.041–1.094, p

This work investigates the conditions for net flow generation by a straight tube with a cross-sectional area harmonically varying in time that connects two tanks—a problem that is mainly found in the design of impedance pumps. By assuming a quasi-one-dimensional flow and applying continuity and momentum equations, a first-order differential equation with respect to the flow rate is derived and presented for the first time, including a nonlinear term that is responsible for net flow rate generation. Namely, the net flow rate is found to be nonzero (as is the nonlinear term) if the cross-sectional areas of the two tanks are unequal and one of them is smaller than that of the straight tube. In this case, the flow is directed from the smaller to the larger tank and the net flow rate increases with the frequency of the tube’s cross-sectional area variation. In contrast, when the tanks’ cross-sections are equal, the net flow is generated only if a valve is installed, e.g., at one end of the tube, due to the large asymmetries imposed in the hydraulic losses with respect to the tube mid-length. Compared with constant valve opening, the net flow rate is augmented significantly if the valve opening is time-dependent. By employing the same equation, the flow rate of an intra-aortic counter-pulsating balloon pump is also examined, in which the valve (representing the aortic valve) opens during the shrinkage of the tube, and it is shown that the net flow rate increases with the frequency and amplitude of the tube’s cross-sectional area. Conclusively, the harmonic oscillation in time of a tube’s wall can cause unidirectional flow only if asymmetric losses are present with respect to its mid-length.

Objective To evaluate the effect of extracorporeal membrane oxygenation combined with intraaortic balloon pump mechanical circulatory support for patients with cardiogenic shock complicating acute myocardial infarction during PCI process. Methods Patients with cardiogenic shock complicating myocardial infarction who underwent PCI in the hospital from January 2015 to December 2019 were selected. Those who were under support of extracorporeal membrane oxygenation combined with intra-aortic balloon pump were enrolled in the observation group, the patients under support of only intra-aortic balloon pump were selectedin the control group. The differences of clinical features and prognosis were compared. Results A total of 40 patients were enrolled, 11 were in the observation group and 29 in the control group. Compared with control group, more patients were complicated with old myocardial infarction (5/11 vs. 2/29, P = 0.016), more patients were diagnosed as non-ST elevated myocardial infarction (8/11 vs. 11/29, P = 0.049) and left ventricular ejecting fraction was lower [(38.5 ± 10.10)vs. (48.55 ± 8.86), P = 0.01］ in observation group. Moreover, the proportion of patients with EF < 35% was higher in the observation group (5/11 vs. 3/29, P = 0.01). The observation group has significantly higher rates of multi-vessel disease and Syntax scores compared to the control group (multi-vessel disease：10/11 vs. 11/29, P = 0.02；Syntax score：[(33.36 ± 13.37)vs. (25.74 ± 5.75), P = 0.015]；the observation group exhibited a higher proportion of patients achieving complete revascularization (9/11 vs. 8/29, P = 0.002). Mechanical complications were higher in observation group (6/11 vs. 5/29, P = 0.02), The survive rate in observation group is higher than that in control group (91.00% vs.55.17%, P = 0.03) at one-year follow-up. Conclusion Compared with only IABP, ECMO combined with IABP hemodynamic support during PCI process for patients with cardiogenic shock complicating acute myocardial infarction enjoys more complete revascularization and better mortality outcome, although it has relatively higher mechanical complications.

Background: Little is known about extracorporeal membrane oxygenation (ECMO)-related spinal cord infarction (SCI), and reports regarding this rare and catastrophic complication are rare. Here, we report two cases of ECMO-related SCI that occurred between April and December 2023. Data were collected from patients' medical records, with SCI as the endpoint. We reviewed previously published reports by searching PubMed and summarizing the findings. Case summary: One female patient presenting with multiple traumas required oxygenation support through veno-venous ECMO (VV ECMO) due to pulmonary hemorrhage, while one male patient required circulatory support via veno-arterial ECMO (VA ECMO) concurrently with an intra-aortic balloon pump due to cardiac arrest. Neither patient had preexisting neurological deficits; however, upon weaning from ECMO, they presented with severe neurological deficits of uncertain etiology, subsequently confirmed as SCI using magnetic resonance imaging. Conclusion: ECMO-related SCI remains elusive and intricate, and this is the first report of adult VV ECMO-related SCI. [ABSTRACT FROM AUTHOR]

Complications were more common in Group C, especially with renal disease. Average preoperative and postoperative stays were 4.0 ± 4.8 days and 15.2 ± 20.4 days, respectively, with no significant differences between groups. Conclusion IABP might offer safety for open-heart surgery, with longer hospital stays potentially associated with high-risk patients. Pre-operative IABP prophylaxis could be crucial in high-risk open-heart cases to reduce mortality. Clinical registration number: NHG DSRB Ref No# 2016/01070 and 2019/00397. [ABSTRACT FROM AUTHOR]

Background: The role of intra-aortic balloon pump (IABP) combined with venoarterial extracorporeal membrane oxygenation (VA-ECMO) in patients with cardiogenic shock (CS) remains unclear. This study investigated the effect of applying IABP for left ventricle (LV) unloading after VA-ECMO on reducing mortality in patients with CS. Methods: Data from 5,492 consecutive patients with CS treated with VA-ECMO between January 2017 and July 2023 were collected from the CSECLS registry. The primary outcome was in-hospital mortality. The secondary outcomes included 30-day mortality, survival on VA-ECMO, and various complications. The association between the application of IABP after VA-ECMO and in-hospital outcomes was assessed. Results: Among 5,492 patients undergoing VA-ECMO (mean age 54.7 ± 15.1 years, 3,917 [71.3%] male), 832 (15.1%) received IABP after VA-ECMO. Before VA-ECMO, a higher incidence of cardiac intervention (13.9% vs. 16.7%) and myocardial infarction (12.0% vs. 14.8%) (all P < 0.05) was seen in the IABP after VA-ECMO group. In this cohort, the IABP after VA-ECMO group had a lower in-hospital mortality (52.5% vs. 48.0%, P = 0.017) and a higher survival rate on VA-ECMO (75.4% vs. 79.4%, P = 0.014). On multivariate modeling, the use of IABP after VA-ECMO was associated with a lower risk of in-hospital mortality (adjusted odds ratio[aOR], 0.823 [95% confidence interval [CI], 0.686–0.987]; P = 0.035) and on-support mortality (aOR, 0.828 [95% CI, 0.688–0.995]; P = 0.044). However, the use of IABP after VA-ECMO was also associated with an increased incidence of complications, including mechanical (aOR: 1.905, [95% CI, 1.278–2.839]; P = 0.002), bleeding (aOR: 1.371, [95% CI, 1.092–1.721]; P = 0.007), renal (aOR: 1.252, [95% CI, 1.041–1.505]; P = 0.017), and pulmonary (aOR: 1.768, [95% CI, 1.446–2.163]; P < 0.001). Conclusion: In this multicenter retrospective study, the use of IABP after VA-ECMO was associated with lower in-hospital mortality in patients with CS. These findings suggest that IABP may offer advantages for LV unloading in patients with CS treated with VA-ECMO, but further validation through randomized controlled trials is warranted to better understand the balance of risks and benefits.

Background: In recent decades, intra‐aortic balloon pump (IABP) technology has made significant progress (sheathless insertion technique, different balloon diameters, percutaneous technique and fibre optic IABP) in reducing complications and increasing patient support. Nonetheless, IABP‐related complications are still frequent and are associated with a poor prognosis. Aim: The aim of this systematic review was to identify complications associated with IABP treatment in critically ill patients with a compromised cardiac function. Study Design: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines based on searches in CINAHL (EBSCO), Medline and Embase (Ovid) from January 2012 to April 2023. Quantitative studies were included if they reported as their primary outcome(s) complications of IABP in adult patients because of cardiovascular conditions and were published in English, Norwegian, Swedish or Danish. Study selection, methodological quality assessment and data extraction were performed independently by two authors. The results were synthesized narratively. Results: A total of nine studies were included in the review, most of which were retrospective (eight of nine). Bleeding was the most frequently occurring complication, followed by limb ischaemia, stroke, infection, IABP malfunction, haematoma and other vascular complications. In addition, a correlation between IABP duration and vascular complications was found in three out of nine studies. Lastly, the incidence rate of stroke was higher in patients with axillary IABP than in those with femoral IABP. Conclusions: This systematic review revealed that bleeding and limb ischaemia were the two most frequent complications associated with IABP therapy. We identified a correlation between (a) IABP support time and the development of vascular complications and (b) stroke and implantation of IABP catheter in the axillary artery. Further studies are needed to explore these findings directly. Relevance to Clinical Practice: Increasing critical care nurses' knowledge regarding complications related to IABP support could lead to early identification, potentially lowering the incidence rate of complications.

Use of Intra-Aortic Balloon Pump (IABP) in combination with Impella has been described as an alternative strategy for mechanical circulatory support (MCS) in patients with cardiogenic shock (CS). We provide a systematic review aimed to explore the effectiveness of this paired MCS approach. We conducted a comprehensive systematic search in MEDLINE, Scopus, and Cochrane databases to identify all studies that investigated dual MCS with IABP and Impella. Our search strategy identified 12 articles, including 1 randomized controlled trial, 1 retrospective study, 1 case series, 7 case report and 2 animal studies. Rationale for this combined MCS strategy stems from an observed reduction in myocardial oxygen demand/supply ratio compared to the use of each device alone, without determining significant variations in left ventricular work. Nonetheless, this combined approach also leads to a 30–40 % decline in Impella flow, increasing the risk of bleeding, Impella displacement, as well as triggering positioning and pressure alarms. Additionally, hemolytic risk data yielded inconclusive results. Importantly, there were no notable disparities in mortality rates when comparing the combined strategy to the use of each device individually. At the current state-of-the-art, there are no conclusive data demonstrating net clinical benefits of combining Impella with IABP. Considering the substantial risks of morbidity associated, we recommend against its use in clinical practice. [Display omitted] • MCS combination is an interesting strategy but need a strong rationale due to side effects. • Impella functioning is severely worsened when combined with IABP. • Hemodynamic benefit of IABP and Impella combination does not justify increased risk. • Expansion of registries on major outcomes is needed to examine dual MCS strategies.

Background: Ventricular septal defect (VSD) is a lethal complication of myocardial infarction. Case presentation: A 67-year-old male who presented with a history of chest pain associated with shock... Physical examination was significant for crepitation in lower lung fields. Echo showed a left ventricular ejection fraction (LVEF) of 30-35% and muscular ventricular septal defects with left to right shunting and elevated pulmonary artery systolic pressure. In a short time, he developed respiratory failure during the hospital course. Our patient had VSD due to acute myocardial infarction (MI). The patient was transferred to another hospital on a ventilator for surgical intervention but died before any procedure. Conclusion: Our case highlights an unfortunate patient with a VSD secondary to myocardial infarction (MI) resulting in Death. [ABSTRACT FROM AUTHOR]

Introduction: Intra-aortic balloon pump (IABP) insertion for diminished myocardial function is standard of care in cardiac surgery. Previous studies have suggested a possible benefit to IABP support before surgery with regards to outcomes and complications. However, there are conflicts with other studies suggesting no significant benefit. Optimal time of insertion, whether preoperative or perioperative (intra-operative and post-operative), has yet to be defined. Methodology: A retrospective, hospital records-based chart review was conducted for patients admitted to our center from January 2015 to December 2019 for coronary bypass surgery necessitating IABP insertion. Cases were stratified according to the timing of insertion and analyzed according to surgical outcomes and complication rates. Results: Out of 97 patients, 84.5% underwent preoperative IABP insertion while 15.5% of patients received perioperative (Intra-operative or post-operative) insertion. In-hospital mortality was significantly higher in patients with perioperative IABP insertion as compared to the preoperative group (60% vs 20.7%, p = 0.003). However, there were no significant differences between 30-day readmission rates in the two groups (9.8% vs 6.7%, p = 1.000). Length of stay was also higher in patients with preoperative insertion of IABP (p = 0.032), with no significant difference in ICU stay (p = 0.107). Perioperative IABP patients had higher rates of arrhythmias (46.7%, p = 0.042) and reopening of patient (33.3%, p = 0.028). Conclusion: Our study shows improved mortality in patients with preoperatively inserted IABP. This may be beneficial for high-risk patients undergoing CABG surgery. Expanding the use of IABP before CABG in third world countries such as Pakistan may improve overall survival for patients. [ABSTRACT FROM AUTHOR]

• In patients receiving temporary MCS, anticoagulation is recommended to prevent device-related thromboembolism. • There are limited data on optimal anticoagulation strategies that balance the risk of bleeding and thrombosis. • The ideal anticoagulant should have short duration of action, reliability in monitoring and titration, and easy reversibility. Cardiogenic shock (CS) is a syndrome of low cardiac output resulting in critical end-organ hypoperfusion and hypoxia. The mainstay of management involves optimizing preload, afterload and contractility. In medically refractory cases, temporary percutaneous mechanical support (MCS) is used as a bridge to recovery, surgical ventricular assist device, or transplant. Anticoagulation is recommended to prevent device-related thromboembolism. However, MCS can be fraught with hemorrhagic complications, compounded by incident multisystem organ failure often complicating CS. Currently, there are limited data on optimal anticoagulation strategies that balance the risk of bleeding and thrombosis, with most centers adopting local antithrombotic stewardship practices. In this review, we detail anticoagulation protocols, including anticoagulation agents, therapeutic monitoring, and complication mitigation in CS requiring MCS. This review is intended to provide an evidence-based framework in this population at high risk for in-hospital bleeding and mortality. [Display omitted] [ABSTRACT FROM AUTHOR]

• In those with cardiac amyloidosis and heart failure-related cardiogenic shock, there was significant augmentation of cardiac index after intra-aortic balloon pump (IABP) and significant decreases in left ventricular and right ventricular filling pressures. • Predictors of lack of response to IABP by cardiac index were a smaller baseline left ventricular end-diastolic diameter size per centimeter and higher pre-IABP systemic vascular resistance. • Most patients with Society for Cardiovascular Angiography and Interventions stage C heart failure-related cardiogenic shock were stabilized successfully and bridged to advanced therapies with IABP alone. In those with heart failure-related cardiogenic shock (HF-CS), an intra-aortic balloon pump (IABP) may improve hemodynamics and be useful as a bridge to advanced therapies. We explore whether those with cardiac amyloidosis and HF-CS might experience hemodynamic improvement and describe the hemodynamic response after IABP. We retrospectively identified consecutive patients with a diagnosis of cardiac amyloid, either light chain or transthyretin, who were admitted to our intensive care unit with HF-CS. Patients were excluded if an IABP was placed during heart transplant or for shock related to acute myocardial infarction. Invasive hemodynamics before and after IABP placement were assessed. We identified 23 patients with cardiac amyloid who had an IABP placed for HF-CS. The 1-year survival rate was 74% and most (65%) were bridged to heart transplant, although 1 patient was bridged to destination left ventricular assist device. After IABP, the mean arterial pressure, cardiac index, and cardiac power index were significantly increased, whereas mean right atrial pressure, mean pulmonary artery pressure, and pulmonary capillary wedge pressure were all significantly decreased. A smaller left ventricular end-diastolic diameter (per cm) was associated with a higher likelihood of a cardiac index of <2.2 L/min/m2 after IABP (odds ratio 0.16, 95% confidence interval 0.01–0.93, P =.04). IABP significantly improved cardiac index while decreasing right atrial pressure, mean pulmonary artery pressure, and pulmonary capillary wedge pressure in cardiac amyloidosis patients with HF-CS.

Background It is unclear whether an intra‐aortic balloon pump (IABP) or percutaneous ventricular assist device (Impella) in combination with extracorporeal membrane oxygenation (ECMO) is better. Methods Using the Japanese Diagnosis Procedure Combination database from September 2016 to March 2022, we identified inpatients who received an Impella or IABP in combination with ECMO (ECPella or ECMO+IABP group, respectively). The primary outcome was in‐hospital mortality, and the secondary outcomes included the length of hospital stay, length of ECMO, total hospitalization cost, complications, and durable mechanical circulatory support implantations. Propensity score matching was performed to compare the outcomes between the groups. Results Of 14 319 eligible patients, 590 (4.1%) received ECPella and 13 729 (96%) received ECMO+IABP. The mean age of patients was 65 years, 77% were men, and 57% had acute coronary syndrome. After propensity score matching, the patient characteristics were well balanced between the groups. The 14‐day mortality rate was lower in the ECPella group than in the ECMO+IABP group (28.0% versus 36.8%; risk difference, −8.2% [95% CI, −13.8 to −2.7]), whereas there was no significant difference in in‐hospital mortality between the groups (58.3% versus 56.6%; risk difference, 2.4% [95% CI, −3.5 to 8.2]). The ECPella group had a higher total hospitalization cost, increased renal replacement therapy during hospitalization, and more durable mechanical circulatory support implantations than the ECMO+IABP group. Conclusions This nationwide inpatient database study showed no significant difference in in‐hospital mortality between the groups, but ECPella was associated with a higher total hospitalization cost, increased renal replacement therapy during hospitalization, and more durable mechanical circulatory support implantations than ECMO+IABP.

Total occlusion of the left main coronary artery (LMCA) is a rare but highly lethal event in acute coronary syndrome. It can lead to extensive myocardial infarction and hemodynamic instability. Despite advancements in percutaneous coronary intervention (PCI), mortality remains high. A 35-year-old male presented with chest pain, dyspnea, and hemodynamic instability. Diagnostic workup revealed LMCA thrombotic occlusion with extensive myocardial involvement and cardiogenic shock (CS). Prompt intervention, including thrombus aspiration, angioplasty, and hemodynamic support with intra-aortic balloon pump and venoarterial extracorporeal membrane oxygenation, was initiated. The patient’s condition gradually improved with comprehensive management, including pharmacotherapy and intensive care support. LMCA occlusion presents challenges due to its extensive myocardial distribution and high mortality rates, particularly when complicated by CS. PCI combined with circulatory support is crucial for restoring perfusion and improving outcomes. Achieving optimal flow and providing postprocedural care significantly impact patient prognosis. Rapid diagnosis and intervention are critical in LMCA occlusion with CS. A multidisciplinary approach incorporating advanced circulatory support and timely revascularization are the keys in improving patient outcomes. Comprehensive postprocedural care is essential for ensuring successful recovery and survival.

Abstract Background The intra-aortic balloon pump (IABP) technique plays a crucial role in providing circulatory support for patients experiencing hemodynamic instability. This study aimed to assess the effectiveness and safety of preoperative prophylactic IABP insertion in patients undergoing acute critical coronary artery bypass grafting (CABG). Methods A comprehensive search was conducted in PubMed, Cochrane Library, and Embase databases, covering the period from January 1995 to September 2022. Results The incidence of renal insufficiency, mechanical ventilation exceeding 24 h, and bleeding events in the IABP group did not exhibit significant differences compared to the control group (relative risk [RR] = 0.85, P = 0.26; RR = 0.81, P = 0.08; RR = 0.95, P = 0.87). However, the hospital mortality rate was significantly lower in the IABP group than in the control group (RR = 0.54, P = 0.0007), and the length of ICU stay was shorter in the IABP group (mean difference [MD] = -1.12, P

Acute aortic dissection (AAD) is a critical condition characterized by the tearing of the aortic wall, posing significant diagnostic challenges due to its diverse clinical presentations. We present the case of a 61-year-old male with hypertension and dyslipidemia who presented with acute abdominal and chest pain, initially raising suspicion of myocardial infarction. Despite an unremarkable electrocardiogram and initially normal troponin levels, the patient experienced ventricular fibrillation, prompting further evaluation. The patient’s clinical course was complicated by recurrent cardiac arrests. Subsequent imaging revealed AAD, which was not initially recognized, emphasizing the importance of maintaining a broad differential diagnosis and the critical need for prompt recognition and management of AAD. This case underscores the necessity of considering AAD in patients with atypical presentations and the pivotal role of advanced imaging techniques in facilitating timely diagnosis and appropriate intervention.

Background: Stress cardiomyopathy (SCM) is an acute heart failure syndrome characterized by transient, usually reversible left ventricular systolic dysfunction with normal or enhanced basal compensatory wall motion abnormalities involving the left ventricular anterior septum and apex, resulting in a "ballooning" appearance. However, it has rarely been reported in patients undergoing spinal surgery. Case presentation: We report a case of severe stress cardiomyopathy in a scoliosis patient with pectus excavatum who underwent spinal corrective surgery. During the wake-up period, circulatory collapse occurred. After multidisciplinary consultation, the patient was diagnosed with stress cardiomyopathy. At last, she had a good prognosis after a series of treatments including ECMO. Conclusion: Stress cardiomyopathy is a reversible but uncommon condition. It can cause death if it is not diagnosed in time. Consequently, this report should improve the awareness of orthopedists and anesthesiologists for timely identification and management. For patients with potential risk factors, timely preoperative intervention should be performed to reduce the occurrence of stress cardiomyopathy. [ABSTRACT FROM AUTHOR]

Background: In patients with ST-elevation myocardial infarction (STEMI), either with or without cardiogenic shock, mechanical circulatory support with an intra-aortic balloon pump (IABP) is not associated with lower mortality. However, in STEMI patients undergoing urgent coronary artery bypass grafting (CABG), preoperative insertion of an IABP has been suggested to reduce mortality. In this study, the effect of preoperative IABP use on mortality in STEMI patients undergoing urgent CABG was investigated. Methods: All consecutive STEMI patients undergoing urgent CABG in a single centre between 2000 and 2018 were studied. The primary outcome, 30-day mortality, was compared between patients with and without a preoperative IABP. Subgroup analysis and multivariable analysis using a propensity score and inverse probability treatment weighting were performed to adjust for potential confounders. Results: A total of 246 patients were included, of whom 171 (69.5%) received a preoperative IABP (pIABP group) and 75 (30.5%) did not (non-pIABP group). In the pIABP group, more patients suffered from cardiogenic shock, persistent ischaemia and reduced left ventricular function. Unadjusted 30-day mortality was comparable between the pIABP and the non-pIABP group (13.3% vs 12.3%, p = 0.82). However, after correction for confounders and inverse probability treatment weighting preoperative IABP was associated with reduced 30-day mortality (relative risk 0.52, 95% confidence interval 0.30–0.88). Conclusion: In patients with STEMI undergoing urgent CABG, preoperative insertion of an IABP is associated with reduced mortality. [ABSTRACT FROM AUTHOR]

Acute heart failure (HF) presents a significant mortality burden, necessitating continuous therapeutic advancements. Temporary mechanical circulatory support (MCS) is crucial in managing cardiogenic shock (CS) secondary to acute HF, serving as a bridge to recovery or durable support. Currently, MCS options include the Intra-Aortic Balloon Pump (IABP), TandemHeart (TH), Impella, and Veno-Arterial Extracorporeal Membrane Oxygenation (VA-ECMO), each offering unique benefits and risks tailored to patient-specific factors and clinical scenarios. This review examines the clinical implications of recent advancements in temporary MCS, identifies knowledge gaps, and explores promising avenues for future research and clinical application. Understanding each device's unique attributes is crucial for their efficient implementation in various clinical scenarios, ultimately advancing towards intelligent, personalized support strategies.

Background: The axillary artery (AX) access for intra‐aortic balloon pump (IABP) as a bridge to heart transplant (HT) allows mobility while awaiting a suitable donor. As end‐stage heart failure patients often have an implantable cardioverter defibrillator (ICD) on the left side, the left AX approach may be avoided due to the perception of difficult access and proximity of two devices. We aimed to evaluate the outcomes of patients bridged to HT with a left‐sided AX IABP with or without ipsilateral ICDs. Methods: We retrospectively reviewed HT candidates at our institution supported by left‐sided axillary IABP from November 2019 to February 2024, dividing them into two groups based on the presence (Group ICD, n = 48) or absence (Group No‐ICD, N = 19) of an ipsilateral left‐sided ICD. The exposure time was defined as the time from skin incision to the beginning of anastomoses of a Dacron graft. Results: Technical success was achieved in 100% of the cohort, with median exposure times for AX access similar between groups (ICD, 12 [7.8, 18.2] vs. No ICD, 11 [7, 19] min; p = 0.75). The rate of procedural adverse events, such as significant access site bleeding and ipsilateral limb ischemia, did not significantly differ between both groups. Device malfunction rates were comparable (ICD, 29.2% vs. No ICD, 15.8%; p = 0.35). Posttransplant, in‐hospital mortality, severe primary graft dysfunction, and stroke rates were comparable in both groups. Conclusion: The presence of an ipsilateral left‐sided ICD does not adversely impact the procedural efficacy, complication rates, or posttransplant outcomes of left‐sided AX IABP insertion in HT candidates.

There is limited real-world data highlighting recent temporal in-hospital morbidity and mortality trends for cases of acute myocardial infarction complicated by cardiogenic shock. The role of mechanical circulatory support within this patient population remains unclear. The US National Inpatient Sample database was sampled from 2011 to 2018 identifying 206,396 hospitalizations with a primary admission diagnosis of ST- or Non-ST elevation myocardial infarction complicated by cardiogenic shock. The primary outcomes included trends of all-cause in-hospital mortality, mechanical circulatory support use, and sex-specific trends for acute myocardial infarction complicated by cardiogenic shock (AMI-CS) over the study period. The annual number of AMI-CS hospitalizations increased from 22,851 in 2011 to 30,015 in 2018 and in-hospital mortality trends remained similar (42.9 % to 43.7 %, ptrend < 0.001). The proportion of patients receiving any temporary MCS device decreased (46.4 % to 44.4 %). The use of intra-aortic balloon pump (IABP) decreased (44.9 % to 32.9 %) and the use of any other non-IABP MCS device increased (2.5 % to 15.6 %), ptrend<0.001. Sex-specific mortality indicate female in-hospital mortality remained similar (50.3 % to 51 %, ptrend<0.001), but higher than male in-hospital mortality, which increased non-significantly (38.8 % to 40.2 %, ptrend = 0.372). From 2011 to 2018, hospitalizations for AMI-CS patients have increased in number. However, there has been no recent appreciable change in AMI-CS mortality despite a changing treatment landscape with decreasing use of IABPs and increasing use of non-IABP MCS devices. Further research is necessary to examine the appropriate use of MCS devices within this population. • AMI complicated by cardiogenic shock (AMI-CS) is a highly morbid condition. • The number of AMI-CS cases has increased from 22,851 in 2011 to 30,015 in 2018 and mortality has remained unchanged at 40–45%. • Intra-aortic balloon pump use in AMI-CS patients is decreasing (44.9% to 32.9%, p-value<0.001). • Use of other temporary mechanical circulatory devices is increasing (2.5% to 15.6%, p-value<0.001). • Mortality of female AMI-CS patients is consistently nearly 10 % higher than males.

Evidence supporting anticoagulation with unfractionated heparin (UFH) in patients with an intra-aortic balloon pump (IABP) to prevent limb ischaemia remains limited, while bleeding risks remain high. Monitoring heparin in this setting with anti-factor Xa (anti-Xa) is not previously described. The study objective is to describe the incidence of thromboembolic and bleeding events with the use of UFH in patients with an IABP utilising monitoring with both anti-Xa and activated partial thromboplastin time (aPTT). This is a retrospective study of adults who received an IABP and UFH for ≥24 hours. Electronic medical records were reviewed for pertinent data. The primary outcome was the incidence of limb ischaemia during IABP. Secondary outcomes included myocardial infarction, thrombus on IABP, or stroke. Exploratory outcomes included any venous thromboembolism and bleeding events. Of 159 patients, 88% received an IABP for cardiogenic shock and median duration of IABP support was 118 hours (interquartile range, 67–196). Limb ischaemia occurred in four of 159 patients (2.5%). Strokes occurred in 3.8% of the cohort, and bleeding events occurred in 33%. Despite anticoagulation use in all patients, 11% experienced a venous thromboembolism, with most identified upon asymptomatic screening with concern for heparin-induced thrombocytopenia. We found no differences in outcomes that occurred with a hybrid anti-Xa and aPTT versus aPTT monitoring alone. We observed a high rate of thrombotic and bleeding complications with the use of UFH in patients with an IABP. Use of anti-Xa versus aPTT for monitoring was not associated with complications. These data suggest safer anticoagulation strategies are needed in this setting. • Utilization of unfractionated heparin titrated to therapeutic aPTT and/or anti-Xa in patients requiring hemodynamic support with an IABP may not be required for all. • Patient characteristics, such as increased thromboembolic or bleeding risk, should be assessed and careful consideration of anticoagulation goals should be determined at the bedside. • Given a paucity of data, evaluation of heparin monitoring with anti-Xa during IABP support requires further investigation. • Further research is needed to understand optimal goals of anticoagulation therapy if utilized, specifically if therapeutic levels are necessary or if prophylactic goals can be targeted to reduce the risk of bleeding without increasing thromboembolic events in patients supported with an IABP.

The function of the right ventricle (RV) is to drive the forward flow of blood to the pulmonary system for oxygenation before returning to the left ventricle. Due to the thin myocardium of the RV, its function is easily affected by decreased preload, contractile motion abnormalities, or increased afterload. While various etiologies can lead to changes in RV structure and function, sudden changes in RV afterload can cause acute RV failure which is associated with high mortality. Early detection and diagnosis of RV failure is imperative for guiding initial medical management. Echocardiographic findings of reduced tricuspid annular plane systolic excursion (<1.7) and RV wall motion (RV S′ <10 cm/s) are quantitatively supportive of RV systolic dysfunction. Medical management commonly involves utilizing diuretics or fluids to optimize RV preload, while correcting the underlying insult to RV function. When medical management alone is insufficient, mechanical circulatory support (MCS) may be necessary. However, the utility of MCS for isolated RV failure remains poorly understood. This review outlines the differences in flow rates, effects on hemodynamics, and advantages/disadvantages of MCS devices such as intra-aortic balloon pump, Impella, centrifugal-flow right ventricular assist devices, extracorporeal membrane oxygenation, and includes a detailed review of the latest clinical trials and studies analyzing the effects of MCS devices in acute RV failure. • RV failure is difficult to diagnose. Utilization of laboratory values, imaging modalities, and various hemodynamic variables can aid in diagnosis. • Physicians should have a high index of suspicion and employ early mechanical support in the management of cardiogenic shock. • Multiple mechanical support devices are available and should be utilized in both isolated RV failure and biventricular failure when appropriate.

Acute aortic dissection (AAD) is a critical condition characterized by the tearing of the aortic wall, posing significant diagnostic challenges due to its diverse clinical presentations. We present the case of a 61-year-old male with hypertension and dyslipidemia who presented with acute abdominal and chest pain, initially raising suspicion of myocardial infarction. Despite an unremarkable electrocardiogram and initially normal troponin levels, the patient experienced ventricular fibrillation, prompting further evaluation. The patient's clinical course was complicated by recurrent cardiac arrests. Subsequent imaging revealed AAD, which was not initially recognized, emphasizing the importance of maintaining a broad differential diagnosis and the critical need for prompt recognition and management of AAD. This case underscores the necessity of considering AAD in patients with atypical presentations and the pivotal role of advanced imaging techniques in facilitating timely diagnosis and appropriate intervention.

Cardiovascular diseases detection or diagnosis on appropriate time is crucial to avoid health complications. In this study, an advanced procedure for classifying changes in the blood pressure has been used analyzing the wave-forms inside the arterial system where such variation can occur due to improper timing in intra-aortic balloon pump (IABP) control. Inaccurate pressure extends with probable injury can be caused by improper timing in the heart valve in both pumping and compression of the balloon. This investigation focuses on accurately recognizing and classifying any irregularities in the artery wave-forms in IABP in the blood pressure initiated by mistiming. Accumulated blood pressure records are used for the progression of providing information to IABP trainer. The wave-forms require pre-handling employing image digitizing software to acquire automated identifications. Any undesirable image features have been removed using Wavelet in MATLAB software. Afterward, such features can be employed to develop a technique for arrangement depending on neural networks. The artificial neural network technique has used marked data to properly detect irregularities in wave-forms in vascular blood pressure due to improper IABP timing. As a result, the validation has proved to appropriately recognize and classify such anomalies, denoting a considerable prospect to improve patient protection with an efficacy of treatment in the area of cardiovascular prescription.

Background: Use of temporary mechanical circulatory support (tMCS) for peripartum cardiomyopathy (PPCM) shock has been described in small cohorts, but not on a national scale. This study compares tMCS, durable MCS (dMCS), and no MCS as bridge to transplant strategies for PPCM. Methods: Female patients ≥14 years, listed for first-time isolated heart transplant (HT) between January 1, 2000 and June 30, 2021, were identified in the United Network for Organ Sharing database. Patients were stratified by receipt of MCS at any point during the waitlist period. Patients on multiple devices were excluded. Results: A total of 1,043 PPCM patients were listed for HT, including 575 bridged on no MCS, 177 on tMCS, and 291 on dMCS. The tMCS cohort included 10 patients on extracorporeal membrane oxygenation, 113 on intra-aortic balloon pump, and 54 on nondischargeable ventricular assist device (VAD) or percutaneous device. The dMCS group primarily received durable VADs. Compared to dMCS, tMCS recipients were more likely to require inotropes, mechanical ventilation, and longer hospitalizations pretransplant (all p 0.05). After multivariable risk adjustment, neither tMCS (adjusted hazard ratio 0.56 [0.06-5.43]) nor dMCS (adjusted hazard ratio 0.36 [0.05-2.82]) significantly predicted 3-year graft survival. Conclusions: Compared to patients bridged to HT on dMCS or no MCS, PPCM patients receiving tMCS are higher acuity candidates but have equivalent post-transplant graft survival.

Background: Left ventricular (LV) overload is a frequent complication during VA-ECMO associated with poor outcomes. Many strategies of LV unloading have been documented but lack of evidence shows which is better. We conducted a network meta-analysis to compare different LV unloading strategies. Methods: We searched databases for all published studies on LV unloading strategies during VA-ECMO. The pre-defined primary outcome was all-cause mortality. Results: 45 observational studies (34235 patients) were included. The Surface Under the Cumulative Ranking values (SUCRA) demonstrated that compared to no unloading strategy (15.4 %), IABP (73.8 %), pLVAD (60.8 %), atrial septostomy (51.2 %), catheter venting (48.8 %) were all associated with decreased all-cause mortality, in which IABP and pLVAD existed statistical significance. For secondary outcomes, no unloading group had the shortest VA-ECMO duration, ICU and hospital length of stay, and the lower risk of complications compared with unloading strategies. IABP was associated with reducing VA-ECMO duration, ICU and hospital length of stay, and the risk of complications (except for hemolysis as the second best) compared with other unloading strategies. Conclusions: LV unloading strategies during VA-ECMO were associated with improved survival compared to no unloading, but the tendency to increase the risk of various complications deserves more consideration.

Concurrent intra-aortic balloon pump (IABP) use has been suggested to reduce mortality in patients with acute coronary syndrome (ACS)-related cardiogenic shock (CS) on veno-arterial extracorporeal membrane oxygenation (ECMO). However, this observation is primarily based on small-scale univariate studies. The aim of this meta-analysis was to evaluate whether concurrent IABP and ECMO were independently associated with reduced mortality in patients with ACS-related CS. We searched Medline, Web of Science, and Embase for studies published up to May 28, 2024. The inclusion criteria were longitudinal observational studies comparing concurrent IABP and ECMO to ECMO alone in ACS-related CS patients, reporting all-cause mortality with multivariate adjustments. The primary outcome was the risk ratio (RR) of short-term mortality. A random-effects model incorporating heterogeneity was used to pool the results. Seven cohort studies, involving 5467 patients, were included. Concurrent IABP and ECMO were associated with a significant reduction in short-term mortality (adjusted RR: 0.64; 95% CI: 0.48–0.87, P = 0.005; I² = 83%). Sensitivity analyses confirmed the robustness of these results. Meta-regression indicated that the proportion of men in each study significantly influenced the outcomes, fully explaining the heterogeneity (I² residual = 0%). Subgroup analyses showed consistent results across various study designs, patient ages, observational durations, and study quality scores. In conclusion, concurrent IABP and ECMO are independently associated with reduced short-term mortality in ACS-related CS patients, particularly in studies with higher proportions of men. These findings support the potential benefits of combined mechanical support in this high-risk population.

Abstract Background The aim of this study was to determine whether pre-operative intra-aortic balloon pump (IABP) insertion improves surgical outcomes in high-risk coronary artery bypass grafting (CABG) patients. Methods Patients with a EuroSCORE II greater than 1.2% who underwent CABG from 2009 to 2016 were included in the study, while those who utilized intra-operative or post-operative IABP were excluded. The analysis included a total of 2907 patients, with 377 patients undergoing preoperative IABP insertion (EuroSCORE II > 5.018%) and 1198 patients in the non-IABP group before matching; after propensity score matching (PSM), both groups consisted of a matched cohort of 250 patients. Results 30-day mortality events occurred in 9 (3.6%) non-IABP group and in 12 (4.8%) IABP patients (OR: 1.33 95%CI: 0.52–3.58). Kaplan-Meier survival curve analysis showed no significant differences between the two groups in mortality up to one year after the operation (p = 0.72). On multivariate analysis, IABP usage among the PSM patients was associated with lower 30-day mortality (OR: 0.28, 95%CI: 0.07–0.92, P-value = 0.043), 90-day mortality (OR: 0.26, 95%CI: 0.08–0.78, P-value = 0.022) and reduced risk of developing severe respiratory disorders (OR: 0.10, 95%CI:0.01–0.50, P-value = 0.011). Conclusion Pre-operative IABP use in high-risk patients reduces 30- and 90-day mortality rates, along with a notable decrease in rates of severe respiratory disorders.

Background There is limited evidence for the use of an intra-aortic balloon pump (IABP) in adult patients with a total cavopulmonary, or Fontan circulation. Case summary A patient in his twenties with a Fontan circulation presented with sepsis, pneumonia, and pulmonary oedema. He was born with a hypoplastic left ventricle, atrioventricular septal defect, and hypoplastic aortic arch, and a total cavopulmonary circulation had been established within his first years of life. Standard of care treatment with antibiotics, non-invasive ventilatory support, loop diuretics, and vasopressors was initiated. Due to persistent pulmonary congestion and increasing general fatigue, an IABP was placed via a femoral artery to offload the failing systemic ventricle. Secondary to IABP treatment, mean arterial pressure rose, and vasodilatory nitroprusside could be introduced. Over 4 days of IABP treatment, the patient's general condition and ventricular systolic function improved significantly. Discussion This case suggests that IABP treatment was important in the recovery of our patient with a Fontan circulation, pneumonia, and heart failure. We propose that during IABP treatment, an increase in stroke volume and a reduction in ventricular filling pressure is achieved, thereby increasing the transpulmonary pressure gradient that is central to pulmonary blood flow in Fontan patients. More definitive evidence is necessary to confirm our hypotheses. [ABSTRACT FROM AUTHOR]

Background and Objectives: Cardiogenic shock (CS) is a potentially severe complication following acute myocardial infarction (AMI). The use of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in these patients has risen significantly over the past two decades, especially when conventional treatments fail. Our aim is to provide an overview of the role of VA-ECMO in CS complicating AMI, with the most recent literature highlights. Materials and Methods: We have reviewed the current VA-ECMO practices with a particular focus on CS complicating AMI. The largest studies reporting the most significant results, i.e., overall clinical outcomes and management of the weaning process, were identified in the PubMed database from 2019 to 2024. Results: The literature about the use of VA-ECMO in CS complicating AMI primarily has consisted of observational studies until 2019, generating the need for randomized controlled trials. The EURO-SHOCK trial showed a lower 30-day all-cause mortality rate in patients receiving VA-ECMO compared to those receiving standard therapy. The ECMO-CS trial compared immediate VA-ECMO implementation with early conservative therapy, with a similar mortality rate between the two groups. The ECLS-SHOCK trial, the largest randomized controlled trial in this field, found no significant difference in mortality at 30 days between the ECMO group and the control group. Recent studies suggest the potential benefits of combining left ventricular unloading devices with VA-ECMO, but they also highlight the increased complication rate, such as bleeding and vascular issues. The routine use of VA-ECMO in AMI complicated by CS cannot be universally supported due to limited evidence and associated risks. Ongoing trials like the Danger Shock, Anchor, and Recover IV trials aim to provide further insights into the management of AMI complicated by CS. Conclusions: Standardizing the timing and indications for initiating mechanical circulatory support (MCS) is crucial and should guide future trials. Multidisciplinary approaches tailored to individual patient needs are essential to minimize complications from unnecessary MCS device initiation. [ABSTRACT FROM AUTHOR]

Introduction: Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) improves end-organ perfusion in cardiogenic shock but may increase afterload, which can limit cardiac recovery. Left ventricular (LV) unloading strategies may aid cardiac recovery and prevent complications of increased afterload. However, there is no consensus on when and which unloading strategy should be used. Methods: An online survey was distributed worldwide via the EuroELSO newsletter mailing list to describe contemporary international practice and evaluate heterogeneity in strategies for LV unloading. Results: Of 192 respondents from 43 countries, 53% routinely use mechanical LV unloading, to promote ventricular recovery and/or to prevent complications. Of those that do not routinely unload, 65% cited risk of complications as the reason. The most common indications for unplanned unloading were reduced arterial line pulsatility (68%), pulmonary edema (64%) and LV dilatation (50%). An intra-aortic balloon pump was the most frequently used device for unloading followed by percutaneous left ventricular assist devices. Echocardiography was the most frequently used method to monitor the response to unloading. Conclusions: Significant variation exists with respect to international practice of ventricular unloading. Further research is required that compares the efficacy of different unloading strategies and a randomized comparison of routine mechanical unloading versus unplanned unloading.

Introduction: The intra-aortic balloon pump (IABP) is one of the most utilized cardiac assist devices. Patients receiving IABP therapy are typically managed in high acuity clinical care areas with limited bed space and high demand. Our center instituted a certified clinical perfusionist (CCP) led initiative to remove IABP catheters in order to reduce IABP therapy time, hasten removal and improve efficiency. Methods: The purpose of the study is to compare outcomes for IABP removal by a certified clinical perfusionist to a physician. The primary outcome measures were site hematoma score and limb related complications. A survey was submitted to bedside nurses, managers/patient care coordinators, CCP's and physicians. The IABP quality assurance database was interrogated for the study. Results: There were 350 patients eligible for inclusion. The cohort was well balanced between CCP (n = 284) and physician (n = 66) groups for patient demographics, indication, insertion specifics and type of medical intervention. The majority of patients had no bruise or hematoma with perfusionist (n = 246, 87%) or physician (n = 58, 88%) (p = 0.78) removal. The physician group demonstrated a higher rate of grade 3 hematomas (p = 0.03). There was no statistically significant difference between CCP and physician groups for limb complications and mortality. Survey results showed an improved efficiency in bed space allocation, physician workload and a decreased IABP support time. Conclusion: There is no difference in limb complications between perfusionist and physician removal of IABP catheters. The survey demonstrate an improvement in resource allocation and efficiency. A perfusionist led IABP removal program can be done safely and may help improve program efficiency. [ABSTRACT FROM AUTHOR]

Background: With the growing population of advanced heart failure, the use of Impella 5.5 has been increasing. Here, we report an effective strategy of removing the intra-aortic balloon pump (IABP) in the setting of escalation of support to Impella 5.5. Results: From January 1, 2022 to June 30, 2022, a total of 6 patients have undergone IABP removal during Impella 5.5 insertion. The IABP was subsequently removed over the long wire with manual compression on the femoral artery to control bleeding. An 8 or 9 Fr short sheath is inserted over the wire. Staged hemostasis was successfully performed in 4 patients, and the remaining two patients required escalation of support to veno-arterial membrane oxygenation as EC-PELLA utilizing the femoral arterial sheath. Conclusion: This does not only achieve secured hemostasis but also enables a smooth transition to further escalate support such as extracorporeal membrane oxygenation support, if necessary.

Purpose of Review: This review will focus on the indications of mechanical circulatory support (MCS) for high-risk percutaneous coronary intervention (PCI) and then analyze in detail all MCS devices available to the operator, evaluating their mechanisms of action, pros and cons, contraindications, and clinical data supporting their use. Recent Findings: Over the last decade, the interventional cardiology arena has witnessed an increase in the complexity profile of the patients and lesions treated in the catheterization laboratory. Patients with significant comorbidity burden, left ventricular dysfunction, impaired hemodynamics, and/or complex coronary anatomy often cannot tolerate extensive percutaneous revascularization. Therefore, a variety of MCS devices have been developed and adopted for high-risk PCI. Summary: Despite the variety of MCS available to date, a detailed characterization of the patient requiring MCS is still lacking. A precise selection of patients who can benefit from MCS support during high-risk PCI and the choice of the most appropriate MCS device in each case are imperative to provide extensive revascularization and improve patient outcomes. Several new devices are being tested in early feasibility studies and randomized clinical trials and the experience gained in this context will allow us to provide precise answers to these questions in the coming years.
