The optimal perioperative management of antiplatelet therapy (APT) therapy in patients undergoing noncardiac surgery (NCS) following percutaneous coronary intervention (PCI) is unclear. We sought to identify predictors of APT cessation in a real-world cohort of patients undergoing NCS within 1 year of PCI.Consecutive patients undergoing PCI at a tertiary center between 2011 and 2018 were prospectively enrolled. Perioperative interruption of APT was defined as cessation of either aspirin or P2YA total of 1092 surgeries corresponding to 747 patients were identified. Overall, there were 487 (44.6%) preoperative antiplatelet interruptions: discontinuation of either P2YIn this contemporary cohort of post-PCI patients undergoing NCS, patient-, angiographic- and surgery-specific factors all affected decision-making regarding APT cessation. Our findings reflective of real-world practice, highlight the importance of a multidisciplinary team approach to individualize decision making in these patients.

Aim Optimal dual antiplatelet therapy (DAPT) in patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) intends to balance ischemic and bleeding risks. Various DAPT de-escalation strategies, defined as switching from a full-dose potent to a reduced dose or less potent P2Y12 inhibitor, have been evaluated in several ACS-PCI trials. We aimed to compare DAPT de-escalation to standard DAPT with full-dose potent P2Y12 inhibitors in ACS patients who underwent PCI. Methods and results PubMed, Google Scholar, and Cochrane Central Register of Controlled Trials were searched for eligible randomized controlled trials. Aspirin monotherapy trials were excluded. Five randomized trials (n = 10 779 patients) that assigned DAPT de-escalation (genetically guided to clopidogrel n = 1242; platelet function guided to clopidogrel n = 1304; unguided to clopidogrel n = 1672; unguided to lower dose n = 1170) vs. standard DAPT (control group n = 5391) were included in this analysis. DAPT de-escalation was associated with a significant reduction in Bleeding Academic Research Consortium ≥2 bleeding (HR 0.57, 95% CI 0.42–0.78; I2 = 77%) as well as major adverse cardiac events, represented in most trials by the composite of cardiovascular mortality, myocardial infarction, stent thrombosis, and stroke (HR 0.77, 95% CI 0.62–0.96; I2 = 0%). Notwithstanding the limited power, consistency was noted across various de-escalation strategies. Conclusion De-escalation of DAPT after PCI for ACS, both unguided and guided by genetic or platelet function testing (PFT), was associated with lower rates of clinically relevant bleeding and ischemic events as compared to standard DAPT with potent P2Y12 inhibitors based on five open-label RCTs reviewed.

There is a paucity of data on the prognostic value of high-sensitivity C-reactive protein (hsCRP) levels in diabetic and nondiabetic patients undergoing percutaneous coronary intervention (PCI).All patients with known baseline hsCRP undergoing PCI at a single tertiary care centre from 2010 to 2017 were included. High hsCRP was defined as3 mg/L. Known causes of elevated hsCRP levels and hsCRP10 mg/L represented exclusion criteria. The 1-year primary outcome was major adverse cardiovascular events (MACE), including all-cause mortality, myocardial infarction (MI), and target-vessel revascularisation (TVR).Among a total of 11,979 patients included, high hsCRP levels were observed in 24.7% of patients without diabetes and 29.8% of patients with diabetes (P0.001). Both diabetics and nondiabetics with high hsCRP levels had increased rates of MACE compared with their counterparts with low hsCRP (diabetics: adjusted hazard ratio [aHR] 1.58, 95% CI 1.27-1.96; nondiabetics: aHR 1.45, 95% CI 1.13-1.86; P interaction = 0.981) primarily driven by increased rates all-cause deaths (diabetics: aHR 2.32, 95% CI 1.42-3.80; nondiabetics: aHR 3.14, 95% CI 1.74-5.65; P interaction = 0.415). Although high hsCRP levels were associated with increased rates of TVR (aHR 1.35, 95% CI 1.04-1.75) and MI (aHR 1.86, 95% CI 1.18-2.93) only in patients with diabetes, no significant interactions were observed between inflammation and diabetes (P interaction = 0.749 and 0.602, respectively).Patients undergoing PCI with high levels of hsCRP, defined as3 mg/L, have worse ischemic outcomes regardless of diabetes status.

Inflammation and procedural complexity are individually associated with adverse outcomes after percutaneous coronary intervention (PCI). We aimed to evaluate the association of high sensitivity C-reactive protein (hsCRP) with adverse events according to PCI complexity. We included patients with available hsCRP levels who underwent PCI at our center from 2012 to 2017. We compared patients with hsCRP ≥3 versus 60 mm. The primary end point was major adverse cardiac events (MACEs) (composite of all-cause death, myocardial infarction, or target vessel revascularization) at 1 year. A total of 11,979 patients were included, of which 2,840 (24%) underwent complex PCI. In those, 767 (27%) had hsCRP ≥3 mg/L. The 1-year incidence of MACE was 6% (noncomplex PCI, low hsCRP), 10% (noncomplex PCI, high hsCRP), 10% (complex PCI, low hsCRP), and 15% (complex PCI, high hsCRP). Overall, hsCRP ≥3 mg/L was associated with an increased risk of MACE compared with hsCRP

Cardiovascular disease constitutes the leading cause of mortality worldwide, irrespective of race/ethnicity. Previous studies have shown that minority patients with acute coronary syndrome have distinct clinical, anatomic, and socioeconomic characteristics which may affect clinical outcomes. We included patients who underwent percutaneous coronary intervention with drug-eluting stents for ST-segment elevation myocardial infarction (STEMI), non-STEMI, or unstable angina in a single center. Patients were stratified into Caucasian, African-American, Hispanic, and Asian. Caucasians were the reference group. The primary end point was major adverse cardiac and cerebrovascular events, composite of death, spontaneous myocardial infarction, or stroke at 1 year. Of 6,800 patients included, 49.7% were Caucasian, 20.7% Hispanic, 17.0% Asian and 12.6% African-American. Caucasians were the oldest, Hispanics and Asians had the highest prevalence of diabetes mellitus whereas African-Americans had more chronic kidney disease. Hispanics and African-Americans had the highest STEMI rates, whereas Asians were more likely to present with unstable angina. Compared with Caucasians, Asians had a lower rate of major adverse cardiac and cerebrovascular events at 1 year (3.9% vs 7.1%; p

ObjectivesTo determine the effect of intravenous ultrasound (IVUS) when used adjunctively with nitinol interwoven bare metal stents in the management of femoropopliteal lesions.BackgroundNitinol interwoven bare metal stents represent an advancement in stent technology; however nominal deployment remains an area of focus. Intravascular Ultrasound (IVUS) has been shown to improve outcomes in both the coronary and peripheral vasculature by providing the operator with greater vessel detail. The use of adjunctive IVUS with Nitinol bare metal stents has not been widely studied.MethodsThis study included a cohort of 200 consecutive patients with peripheral artery disease. All patients were treated with ≥1 Supera bare metal stent, and 91 received adjunctive IVUS imaging prior to stent deployment. Deployment conditions of nominal, compressed, and elongated were measured and the primary clinical outcomes included target lesion reintervention, major and minor, below the knee amputation, and mortality.ResultsThe patients who received IVUS had a significantly greater number of nominally deployed stents (pConclusionIVUS and angiography decreases clinically driven target lesion reintervention and increases nominal deployment compared to angiography alone in femoropopliteal lesions treated with interwoven bare metal nitinol stents.Condensed AbstractThis retrospective study was done to examine the utility of intravenous ultrasound when used adjunctively for visualization in the management of femoropopliteal lesions in peripheral artery disease patients. There was total of 200 subjects and all were treated using the Supera nitinol self-expanding stent. By the end of the study, the group of subjects treated with intravenous ultrasound had significantly fewer reinterventions and had a greater rate of nominally deployed stents. These findings suggest the beneficial role intravenous ultrasound has compared to angiography alone in the management of femoropopliteal lesions with Supera stents.

Objectives We assessed the impact of conventional delivery system (DS) insertion technique on "Hat-marker" orientation/commissural alignment in patients who underwent transcatheter aortic valve replacement (TAVR) in the Evolut Low Risk Trial CT substudy versus a modified technique. Background Unlike surgical aortic valve replacement, where alignment of the surgical valve commissures with native commissures can be achieved virtually 100% of the time, commissural alignment during TAVR is not achieved consistently. This may subsequently impact the feasibility of both coronary access and reintervention after TAVR. Methods "Hat-marker" orientations during deployment were characterized as outer curve (OC), center front (CF), inner curve, and center back. Severe commissure-to-CA overlap was 0-20°. "Hat-marker" orientations and CA overlap were compared to 240 patients from a single center using the modified 3-o'clock flush port DS technique. Results In the CT substudy in which conventional DS insertion was performed (flush port at 12 o'clock); 154/249 had both analyzable CT and procedural fluoroscopy to validate "Hat-marker" to C-tab/commissural orientation. On post-TAVR CT, Evolut valve commissural orientation and coronary artery (CA) ostia were identified. Compared to conventional DS technique in the CT substudy, the modified technique had higher rates of "Hat-marker" at OC/CF orientation, improved commissural alignment and reduced severe CA overlap; (left main, 14.2 vs. 27.9%; right coronary artery, 11.7 vs. 27.3% both, 5.0 vs. 13.6%; 1 or both CA, 20.8 vs. 41.6%, all p Conclusions The modified technique improved initial "Hat-marker" orientation during Evolut deployment and resulted in better commissural alignment and reduced CA overlap.

We assessed the clinical outcomes of patients with critical limb-threatening ischemia (CLTI) who underwent interwoven nitinol stent (Supera) implantation for significant stenoses of the femoropopliteal segment. In this retrospective cohort study, 116 consecutive patients with CLTI who were treated with Supera stents between September 2015 and March 2020 were included in this analysis. Primary endpoint analysis was completed for amputation-free survival, target lesion revascularization (TLR), and mortality. After a mean follow-up time of 3.4 years, 21 (18%) patients had undergone amputations, 3 (2.6%) died, and, overall, the amputation-free survival rate was 81%. TLR occurred in 21 (18%) patients, resulting in the freedom from target lesion revascularization of 82%. The average Wagner score for all patients was 2.8 ± 1.1. A subgroup analysis of 57 patients revealed a median ulcer size of 3.0 cm2 [1.65, 9.0], with complete healing for 45 patients by 20 months. The Wagner score of this subgroup decreased by an average of 3.4 ± .9 points. Supera stents can be used together with other endovascular therapies and are a safe and effective treatment modality for CLTI.

Background Potent P2Y12 inhibitors are recommended in patients with acute coronary syndrome (ACS), although the optimal antithrombotic strategy should be tailored based on patients thrombotic and hemorrhagic risk profile. We evaluated if the benefits associated with prasugrel vs. clopidogrel in ACS patients undergoing percutaneous coronary intervention (PCI) are similar in patients with different thrombotic risk profiles. Methods PROMETHEUS was a multicenter observational study comparing prasugrel vs. clopidogrel in ACS patients undergoing PCI. Patients were defined at high thrombotic risk if presenting with a clinical and a procedural risk feature. The primary endpoint was major adverse cardiac events (MACE), composite of death, myocardial infarction, stroke, or unplanned revascularization. Hazard ratio (HR) and 95% confidence intervals (CI) were calculated using propensity-stratified analysis and with multivariable Cox regression. Results Among 16,065 patients, 4,293 were defined at high and 11,772 at low-to-moderate thrombotic risk. Patients receiving prasugrel had less comorbidities and risk factors than those treated with clopidogrel, both in the high and low-to-moderate thrombotic risk strata. High thrombotic risk patients had increased rates of ischemic and bleeding events at 90-day and 1-year follow-up. Patients treated with prasugrel had a lower adjusted 1-year risk of MACE (HR 0.86, 95% CI 0.77-0.96), irrespective of their thrombotic risk (pinteraction =0.32). Stratifying the study population by number of risk factors there was a significant interaction (pinteraction =0.026) for a greater reduction in MACE with prasugrel among patients with ≤1 thrombotic risk factor. The risk of clinically significant bleeding was similar in patients treated with prasugrel and clopidogrel. Conclusions Patients with ACS at high thrombotic risk who undergo PCI are at increased risk of adverse events at 1 year. Prasugrel, mainly reserved to patients with less comorbidities, reduced the risk of ischemic events both in patients at high and low-to-moderate thrombotic risk as compared with clopidogrel.

Valve-in-valve (ViV) transcatheter procedures are the preferred option for redo valve replacement in patients who otherwise would be high risk for surgery. Transesophageal echocardiography (TEE) is an integral imaging modality for both peri-procedural and intra-procedural guidance during transcatheter ViV replacement. When intentional leaflet laceration is needed, such as with the BASILICA (Bioprosthetic or native Aortic Scallop Intentional Laceration to prevent Iatrogenic Coronary Artery obstructions during TAVR) or LAMPOON (Laceration of the Anterior Mitral valve leaflet to Prevent left ventricular Outlet ObstructioN) procedures, TEE is critical to proper guidewire positioning and achieving a successful laceration. In this paper we detail the role of TEE in ViV transcatheter valve replacement in patients with prior surgical aortic, mitral, tricuspid, and pulmonic valves.

Aims To evaluate the acute and chronic patterns of myocardial injury among patients with coronavirus disease-2019 (COVID-19), and their mid-term outcomes. Methods and results Patients with laboratory-confirmed COVID-19 who had a hospital encounter within the Mount Sinai Health System (New York City) between 27 February 2020 and 15 October 2020 were evaluated for inclusion. Troponin levels assessed between 72 h before and 48 h after the COVID-19 diagnosis were used to stratify the study population by the presence of acute and chronic myocardial injury, as defined by the Fourth Universal Definition of Myocardial Infarction. Among 4695 patients, those with chronic myocardial injury (n = 319, 6.8%) had more comorbidities, including chronic kidney disease and heart failure, while acute myocardial injury (n = 1168, 24.9%) was more associated with increased levels of inflammatory markers. Both types of myocardial injury were strongly associated with impaired survival at 6 months [chronic: hazard ratio (HR) 4.17, 95% confidence interval (CI) 3.44–5.06; acute: HR 4.72, 95% CI 4.14–5.36], even after excluding events occurring in the first 30 days (chronic: HR 3.97, 95% CI 2.15–7.33; acute: HR 4.13, 95% CI 2.75–6.21). The mortality risk was not significantly different in patients with acute as compared with chronic myocardial injury (HR 1.13, 95% CI 0.94–1.36), except for a worse prognostic impact of acute myocardial injury in patients Conclusion Chronic and acute myocardial injury represent two distinctive patterns of cardiac involvement among COVID-19 patients. While both types of myocardial injury are associated with impaired survival at 6 months, mortality rates peak in the early phase of the infection but remain elevated even beyond 30 days during the convalescent phase.

Perioperative cardiovascular complications are important causes of morbidity and mortality associated with non-cardiac surgery, especially in patients with recent percutaneous coronary intervention (PCI). We aimed to illustrate the types and timing of different surgeries occurring after PCI, and to evaluate the risk of thrombotic and bleeding events according to the perioperative antiplatelet management. Patients undergoing urgent or elective non-cardiac surgery within 1 year of PCI at a tertiary-care center between 2011 and 2018 were included. The primary outcome was major adverse cardiac events (MACE; composite of death, myocardial infarction, or stent thrombosis) at 30 days. Perioperative bleeding was defined as ≥ 2 units of blood transfusion. A total of 1092 surgeries corresponding to 747 patients were classified by surgical risk (low: 50.9%, intermediate: 38.4%, high: 10.7%) and priority (elective: 88.5%, urgent/emergent: 11.5%). High-risk and urgent/emergent surgeries tended to occur earlier post-PCI compared to low-risk and elective ones, and were associated with an increased risk of both MACE and bleeding. Preoperative interruption of antiplatelet therapy (of any kind) occurred in 44.6% of all NCS and was more likely for procedures occurring later post-PCI and at intermediate risk. There was no significant association between interruption of antiplatelet therapy and adverse cardiac events. Among patients undergoing NCS within 1 year of PCI, perioperative ischemic and bleeding events primarily depend on the estimated surgical risk and urgency of the procedure, which are increased early after PCI. Preoperative antiplatelet interruption was not associated with an increased risk of cardiac events.

Recent trials and meta-analysis have indicated that complete revascularization (CR) of multivessel coronary disease is beneficial in patients with ST-segment elevation myocardial infarction (STEMI) compared to culprit-only intervention. However, the optimal timing of CR remains unclear. We aimed to analyze the optimal timing of CR in patients with STEMI and multivessel disease by performing an updated network meta-analysis using the recent largest randomized controlled trial. PUBMED and EMBASE were searched through October 2020 to identify randomized controlled trials comparing CR and culprit-only revascularization. A random-effect network meta-analysis comparing three arms (same-sitting [during the index procedure] CR versus staged CR versus culprit-only) and 4 arms (same-sitting CR versus staged CR [in-hospital] versus staged CR [out-hospital] versus culprit-only) were performed. Eleven studies with a total of 7,015 patients were included in our analysis. There was no significant difference in major adverse cardiovascular event (MACE) (HR 0.82, 95% CI 0.64-1.05), cardiovascular death (HR 0.69, 95%CI 0.35-1.33), myocardial infarction (HR 0.66, 95%CI 0.37-1.16), and revascularization (HR 1.05, 95%CI 0.70-1.58) between same-sitting CR and staged CR. When staged CR was further divided into staged CR during the hospitalization and after discharge, there was no significant difference in these outcomes between staged CR (in-hospital) and staged CR (out-hospital). In conclusion, in patients with multivessel disease presenting with STEMI, complete revascularization at any timing, including same-sitting, staged in-hospital, and staged out-hospital, may have similar benefits.

Background In the COAPT trial, transcatheter mitral valve repair with the MitraClip plus maximally tolerated guideline-directed medical therapy (GDMT) improved clinical outcomes compared with GDMT alone in symptomatic patients with heart failure (HF) and 3+ or 4+ secondary mitral regurgitation (SMR) due to left ventricular (LV) dysfunction. Aims In this COAPT substudy, we sought to evaluate two-year outcomes in HF patients with reduced LV ejection fraction (HFrEF; LVEF ≤40%) versus preserved LVEF (HFpEF; LVEF >40%) and in those with severe (LVEF ≤30%) versus moderate (LVEF >30%) LV dysfunction. Methods The principal effectiveness outcome was the two-year rate of death from any cause or HF hospitalisations (HFH). Subgroup analysis with interaction testing was performed according to baseline LVEF; 472 patients (82.1%) had HFrEF (mean LVEF 28.0%±6.2%; range 12% to 40%) and 103 (17.9%) had HFpEF (mean LVEF 46.6%±4.9%; range 41% to 65%), while 292 (50.7%) had severely depressed LVEF (LVEF ≤30%; mean LVEF 23.9%±3.8%) and 283 (49.3%) had moderately depressed LVEF (LVEF >30%; mean LVEF 39.0%±6.8%). Results The two-year rate of death or HFH was 56.7% in patients with HFrEF and 53.4% with HFpEF (HR 1.16, 95% CI: 0.86-1.57, p=0.32). MitraClip reduced the two-year rate of death or HFH in patients with HFrEF (HR 0.50, 95% CI: 0.39-0.65) and HFpEF (HR 0.60, 95% CI: 0.35-1.05), pint=0.55. MitraClip was consistently effective in reducing the individual endpoints of mortality and HFH, improving MR severity, quality of life, and six-minute walk distance in patients with HFrEF, HFpEF, LVEF ≤30%, and LVEF >30%. Conclusions In the COAPT trial, among patients with HF and 3+ or 4+ SMR who remained symptomatic despite maximally tolerated GDMT, the MitraClip was consistently effective in improving survival and health status in patients with severe and moderate LV dysfunction and those with preserved LVEF.

The COVID-19 infection adversely affects the cardiovascular system. Transthoracic echocardiography has demonstrated diagnostic, prognostic and therapeutic utility. We report biventricular myocardial strain in COVID-19. Methods: Biventricular strain measurements were performed for 12 patients. Patients who were discharged were compared with those who needed intubation and/or died. Results: Seven patients were discharged and five died or needed intubation. Right ventricular strain parameters were decreased in patients with poor outcomes compared with those discharged. Left ventricular strain was decreased in both groups but was not statistically significant. Conclusion: Right ventricular strain was decreased in patients with poor outcomes and left ventricular strain was decreased regardless of outcome. Right ventricular strain measurements may be important for risk stratification and prognosis. Further studies are needed to confirm these findings.

Examine the impact of acute changes in left heart strain and volumes with percutaneous edge-to-edge MitraClip repair on improvement in health status assessed using Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) score.Changes in left atrial strain, left ventricular (LV) global longitudinal strain (LVGLS), LV end-systolic volume (LVESV), and end-diastolic volume (LVEDV) were evaluated in 50 patients undergoing MitraClip repair for symptomatic primary mitral regurgitation (PMR) and secondary mitral regurgitation (SMR) on transthoracic echocardiography before and 1 month after MitraClip. Multivariable regression was used to evaluate changes in left heart strain and volumes as predictors of change in KCCQ-12 scores, adjusting for baseline clinical and echocardiographic characteristics.Both PMR and SMR patients had significant increase in LVGLS and reduction in LVEDV and LVESV ( P 0.05) after MitraClip, reduction trend in left atrial conduit strain (PMR P = 0.053; SMR P = 0.12) but no significant change in LV ejection fraction. KCCQ-12 score improved significantly in both PMR ( P 0.001) and SMR cohorts ( P 0.001). Higher delta KCCQ-12 tertiles were associated with greater reduction in LVEDV ( P = 0.022) after MitraClip. On multiple regression analysis, lower preprocedural Society of Thoracic Surgeons for Mitral Valve Replacement and KCCQ-12 score, and greater reduction in LVESV and left atrial strain conduit phase were associated with KCCQ-12 score improvement ( P 0.001).There is a significant increase in LVGLS and reduction in LVEDV, LVESV and left atrial strain conduit after edge-to-edge MitraClip repair in both PMR and SMR. Lower preprocedural Society of Thoracic Surgeons for Mitral Valve Replacement and KCCQ-12 score, and greater reduction in LVESV and left atrial conduit strain were associated with KCCQ-12 score improvement after MitraClip. Further studies are warranted to understand the mechanism and significance of our findings.

Background: Sub-Optimal deployment of Self expanding interwoven stents (Supera) has been shown to increase the rate of Clinically Driven Target Lesion Revascularization (CD-TLR). Meanwhile, drug eluting balloons (DCB) have been shown to reduce CD-TLR in the femoral-popliteal segment in de- novo and restenotic lesions. However, the clinical effects of adjunctive DCB in nominal, compressed, and elongated Supera has not been widely studied . Objectives: The purpose of this study is to assess the outcomes of clinically driven re-intervention, major amputations, and mortality in relation to the adjunctive use of DCB in different deployment conditions (nominal, compressed, elongated) of the Supera stent. Methods: Patient chart data was collected at a single center hospital between March 2015 to May 2020. All patients were adults (≥18 years old) and were treated with at least one (≥1) Supera stent. Deployment status was extrapolated from anonymized angiograms. The primary endpoint of this study was CD-TLR. Secondary endpoints included amputation and mortality rates associated with each deployment condition. Results: A total of 670 limbs were treated and patients were followed for 36 months. Nominal stent deployment was observed in 337 limbs, followed by elongated condition (n=176), then by compressed conditions (n=159). CD-TLR was observed most frequently with elongated deployment. Adjunctive drug coated balloon use showed a protective effect regardless of deployment status; O.R=0.44 (CI: 0.30-0.66, pConclusions: Adjunctive DCB with Supera deployment was found to provide a protective effect in reintervention regardless of deployment status.

Conventional echocardiographic assessment may overestimate the left ventricular (LV) function in mitral regurgitation (MR). LV global longitudinal strain (GLS) is more sensitive marker to detect subclinical LV dysfunction. Multiple studies have investigated the prognostic value of LV-GLS in MR to examine its potential to determine the timing and indication of intervention. This systematic review aimed to assess the prognostic value of LV-GLS in patients with mitral regurgitation (MR) to define its clinical applicability. PUBMED and EMBASE were queried through July 2021 to identify studies investigating the prognostic value of LV-GLS in MR. A total of 24 observational studies with 5267 patients were identified. Sixteen studies investigated for primary MR, 7 studies for secondary MR, and 1 study for both. Most studies included patients who underwent intervention. There was significant heterogeneity in patient population, intervention status, follow-up period, LV-GLS cutoff value, outcomes, and statistical methods among the studies. Meta-analysis was not performed considering the significant variability. With exception to 1 study, all studies demonstrated significant association between impaired LV-GLS and worse clinical and echocardiographic outcomes in primary MR. Prognostic value of LV-GLS in secondary MR was less certain due to inconsistent findings and limited reporting. LV-GLS is a promising parameter of prognostication in primary MR and can be considered as alternative to determine the timing of intervention. However, the optimal cutoff value remains unclear. The prognostic value of LV-GLS in secondary MR is less clear. Further large-scale prospective study is warranted before its routine clinical application.

A universal definition to identify patients at higher risk of complications after percutaneous coronary intervention (PCI) is lacking. We aimed to validate a recently developed score to identify patients at increased risk of all-cause death after PCI. All consecutive patients from a large PCI registry not presenting with ST-elevation myocardial infarction or cardiogenic shock were included. Each patient was assigned a score obtained by summing the points associated with the following variables: age80 years (3 points), dialysis (6 points), left ventricular ejection fraction30% (2 points), and multivessel PCI (2 points). Patients were stratified in 3 groups: low risk (score 0), intermediate risk (score 2 to 3), or high risk (score ≥4). The primary outcome was all-cause death, and the secondary outcomes were major adverse cardiovascular events and major bleeding. Events were assessed at 1 year after PCI. Between January 2014 and December 2019, 12,689 patients underwent PCI. Compared with the 9,884 patients at low risk, those at intermediate and high risk had a fourfold (hazard ratio 3.99, 95% confidence interval 2.95 to 5.38) and ninefold (hazard ratio 9.55, 95% confidence interval 6.89 to 13.2) higher hazard for all-cause death at 1 year, respectively. The score had a good predictive value for all-cause death at 1 year (area under the curve 0.70). The risk of major adverse cardiovascular events and major bleeding increased consistently from the low- to the high-risk group. In conclusion, in patients who underwent PCI for stable ischemic heart disease or non-ST-elevation acute coronary syndrome, a score based on 4 variables well predicted the risk of all-cause death at 1 year.

Objectives The aim of this study was to assess the outcomes of severe prosthesis-patient mismatch (PPM) in the TVT (Transcatheter Valve Therapy) Registry in patients undergoing supra-annular transcatheter aortic valve replacement (TAVR) for de novo stenosis or failed surgical bioprostheses (transcatheter aortic valve [TAV]–in–surgical aortic valve [SAV]). Background Severe PPM has been associated with adverse outcomes following TAVR, yet the clinical outcome of severe PPM after supra-annular TAVR is largely unknown. Methods Supra-annular TAVR was performed in patients enrolled in the TVT Registry with de novo stenosis (n = 42,174) or TAV-in-SAV (n = 5,446). Valve Academic Research Consortium-3 criteria were used to define severe PPM. The clinical impact of severe PPM on 1-year mortality and valve-related readmission was assessed using multivariate regression. A generalized linear mixed model was used to evaluate predictors of severe PPM. Results Severe PPM was found in 5.3% of patients undergoing de novo TAVR and 27.0% of patients undergoing TAV-in-SAV. The presence of severe PPM was not significantly associated with 1-year mortality or valve-related readmissions in both groups. Mean aortic gradients were higher in patients with severe PPM than in those without severe PPM at 1 month (9.7 ± 5.7 mm Hg vs. 7.3 ± 4.0 mm Hg; p Conclusions Severe PPM after supra-annular TAVR was not associated with increased 1-year mortality or valve-related readmissions. Longer-term follow-up is needed to determine if higher residual gradients in patients with severe PPM predict long-term outcomes.

BACKGROUND AND AIM OF THE STUDY: A systematic approach to quantify mitral annular calcification (MAC) in all-comers by multidetector computed tomography (MDCT) is essential to guide treatment, but lacking. METHODS From September 2015 to July 2019, 82 patients with MAC underwent MDCT at two institutions to evaluate for surgical mitral valve replacement (SMVR), transcatheter mitral valve replacement (TMVR), or medical management. Type 1 MAC was defined as

Severe tricuspid valve (TV) regurgitation (TR) has been associated with adverse long-term outcomes in several natural history studies, but isolated TV surgery presents high mortality and morbidity rates. Transcatheter tricuspid valve interventions (TTVI) therefore represent a promising field and may currently be considered in patients with severe secondary TR that have a prohibitive surgical risk. Tricuspid transcatheter edge-to-edge repair (T-TEER) represents one of the most frequently used TTVI options. Accurate imaging of the tricuspid valve (TV) apparatus is crucial for T-TEER preprocedural planning, in order to select the right candidates, and is also fundamental for intraprocedural guidance and post-procedural follow-up. Although transesophageal echocardiography represents the main imaging modality, we describe the utility and additional value of other imaging modalities such as cardiac CT and MRI, intracardiac echocardiography, fluoroscopy, and fusion imaging to assist T-TEER. Developments in the field of 3D printing, computational models, and artificial intelligence hold great promise in improving the assessment and management of patients with valvular heart disease.

Objectives The aim of this study was to evaluate post–percutaneous coronary intervention (PCI) outcomes in relation to pre-procedural glycated hemoglobin (HbA1c) levels from a large, contemporary cohort. Background There are limited data evaluating associations between HbA1c, a marker of glycemic control, and ischemic risk following PCI. Methods All patients with known HbA1c levels undergoing PCI at a single institution between 2009 and 2017 were included. Patients were divided into 5 groups on the basis of HbA1c level: ≤5.5%, 5.6% to 6.0%, 6.1% to 7.0%, 7.1% to 8.0%, and >8.0%. The primary endpoint was major adverse cardiac events (MACE), a composite of all-cause death or myocardial infarction (MI), at 1-year follow-up. Results A total of 13,543 patients were included (HbA1c ≤5.5%, n = 1,214; HbA1c 5.6% to 6.0%, n = 2,202; HbA1c 6.1% to 7.0%, n = 4,130; HbA1c 7.1% to 8.0%, n = 2,609; HbA1c >8.0%, n = 3,388). Patients with both low (HbA1c ≤5.5%) and high (HbA1c >8.0%) levels displayed an increased risk for MACE compared with those with values between 6.1% and 7.0%. Excess risk was driven primarily by higher rates of all-cause death among those with low HbA1c levels, while higher values were strongly associated with greater MI risk. Patterns of risk were unchanged among patients with serial HbA1c levels and persisted after multivariate adjustment. Conclusions Among patients undergoing PCI, pre-procedural HbA1c levels display a U-shaped association with 1-year MACE risk, a pattern that reflects greater risk for death in the presence of low HbA1c (≤5.5%) and higher risk for MI with higher values (>8.0%).

Aims Technological advancements have transformed healthcare. System delays in transferring patients with ST-segment elevation myocardial infarction (STEMI) to a primary percutaneous coronary intervention (PCI) centre are associated with worse clinical outcomes. Our aim was to design and develop a secure mobile application, STEMIcathAID, streamlining communication, and coordination between the STEMI care teams to reduce ischaemia time and improve patient outcomes. Methods and results The app was designed for transfer of patients with STEMI to a cardiac catheterization laboratory (CCL) from an emergency department (ED) of either a PCI capable or a non-PCI capable hospital. When a suspected STEMI arrives to a non-PCI hospital ED, the ED physician uploads the electrocardiogram and relevant patient information. An instant notification is simultaneously sent to the on-call CCL attending and transfer centre. The attending reviews the information, makes a video call and decides to either accept or reject the transfer. If accepted, on-call CCL team members receive an immediate push notification and begin communicating with the ED team via a HIPAA compliant chat. The app provides live GPS tracking of the ambulance and frequent clinical status updates of the patient. In addition, it allows for screening of STEMI patients in cardiogenic shock. Prior to discharge, important data elements have to be entered to close the case. Conclusion We developed a novel mobile app to optimize care for STEMI patients and facilitate electronic extraction of relevant performance metrics to improve allocation of resources and reduction of costs.

Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of aortic stenosis, providing a viable alternative to surgical aortic valve replacement (SAVR) for patients deemed to be at prohibitive surgical risk, but also for selected patients at intermediate or low surgical risk. Nonetheless, there still exist uncertainties regarding the optimal management of patients undergoing TAVR. The selection of the optimal bioprosthetic valve for each patient represents one of the most challenging dilemmas for clinicians, given the large number of currently available devices. Limited follow-up data from landmark clinical trials comparing TAVR with SAVR, coupled with the typically elderly and frail population of patients undergoing TAVR, has led to inconclusive data on valve durability. Recommendations about the use of one device over another in given each patient’s clinical and procedural characteristics are largely based on expert consensus. This review aims to evaluate the available evidence on the performance of different devices in the presence of specific clinical and anatomic features, with a focus on patient, procedural, and device features that have demonstrated a relevant impact on the risk of poor hemodynamic valve performance and adverse clinical events.

Managing percutaneous coronary intervention (PCI) patients with atrial fibrillation (AF) presents challenges given that there are several potential antithrombotic therapy (ATT) strategies.We examined ATT patterns, agreement between subjective physician ratings and validated risk scores, physician-patient perceptions influencing ATT and 1-year outcomes.The AVIATOR 2 prospective registry enrolled 514 non-valvular AF-PCI patients from 11 sites. Treating physicians selected ATT and completed smartphone surveys rating stroke and bleeding risks, compared against CHAThe mean patient age was 73.2±9.0 years, including 25.8% females. Triple therapy (TT: 1 anticoagulant and 2 antiplatelet agents) was prescribed in 66.5%, dual antiplatelet therapy (DAPT) in 20.7% and dual therapy (1 anticoagulant+1 antiplatelet agent) in 12.8% of patients. Physician ratings and validated risk scores showed poor agreement (stroke: kappa=0.03; bleeding: kappa=0.07). Physicians rated bleeding-related safety (93.8%) as the main factor affecting ATT choice. Patients worried about stroke over bleeding (50.6% vs 14.8%). No group differences by ATT strategy were observed in 1-year MACCE (TT 14.1% vs dual therapy 12.7% vs DAPT 18.5%; p=0.25), or actionable bleeding (14.7% vs 7.9% vs 15.1%, respectively; p=0.89).The AVIATOR 2 study is the first digital health study examining physician-patient perspectives on ATT choices after AF-PCI. TT was the most common strategy without differences in 1-year outcomes in ATT strategy. Physicians rated safety first when prescribing ATT; patients feared stroke over bleeding.gov: NCT02362659.
