Objectives: The presence of a mechanical aortic valve has been a contraindication to the use of an arch branch aortic endograft due to the risk of damaging the valve, resulting in acute aortic regurgitation, or a trapped endograft. Methods: We present a 67-year-old woman, with a background of Marfan's syndrome and a previous Bentall's procedure, who presented with a symptomatic enlarging aortic arch and descending thoracic aortic aneurysm, with a type 1A endoleak. Results: Using an inner branch arch endograft (Cook Medical, Bloomington, Indiana), the nose cone of the delivery system was passed laterally through the semi-circular aperture of the mechanical aortic valve to facilitate deployment just distal to the coronary buttons. Conclusions: With advancement of endovascular technology, techniques and experience, endovascular aortic arch repair in the presence of a mechanical aortic valve is feasible. [ABSTRACT FROM AUTHOR]

Fenestrated and branched endovascular repair of complex abdominal and thoracoabdominal aortic aneurysms is increasingly replacing open repair as the primary modality of treatment. Mid- and long-term results are encouraging and support its use in the correct settings. Nevertheless, appropriateness of indication for treatment, patient selection, and surgeon and hospital performance has not been clearly evaluated and reviewed. The objective of this review article was to identify areas in which appropriateness of care is relevant and can be optimized when considering treatment of patients with fenestrated and branched endovascular repair for complex abdominal and thoracoabdominal aortic aneurysms.

BackgroundThoracic endovascular aortic repair (TEVAR) has increasingly become the preferred surgical intervention for Stanford type B aortic dissection (TBAD). The primary objective of this procedure is to seal the primary entry tear to promote positive aortic remodeling. However, the increased use of TEVAR has also led to a rise in surgical complications. Among these, the accidental deployment of the stent into the false lumen is a rare but serious complication that can result in aortic false lumen rupture and inadequate perfusion of abdominal organs.Case summaryThis case report described a 78-year-old man who presented to our hospital with sudden onset chest and back pain and was subsequently diagnosed with TBAD via aortic CTA. As conventional medical therapy failed to alleviate his chest pain, the patient underwent TEVAR. During the procedure, a complication arose when the distal end of the endograft was mistakenly deployed into the false lumen, leading to insufficient perfusion of the abdominal organs. Recognizing this issue intraoperatively, an additional endograft was promptly inserted at the distal end to reroute blood flow back to the true lumen of the aorta, thereby restoring visceral perfusion. Post-intervention, the patient's chest pain improved, and he was successfully discharged from the hospital.ConclusionAccidental deployment of a endograft into the false lumen during TEVAR is a rare but serious complication. Intraoperative angiography plays a crucial role in rapidly and accurately identifying this issue by detecting insufficient perfusion of abdominal organs. The use of intravascular ultrasound may help reduce the incidence of this complication. Endovascular repair is an effective emergency strategy to quickly redirect blood flow back to the true lumen, making it the preferred method for managing such emergencies.

Background: Blood glucose level variability has been associated with increased risk of complication in the postoperative setting of cardiovascular surgery. Although interesting for optimization of blood glucose management in this context, continuous blood glucose (CBG) devices can have a limited reliability in this context, in particular because of the use of paracetamol. The aim of this study was to evaluate the reliability of Dexcom G6®, a recently developed continuous glucose monitoring device. Methods: We performed a prospective, observational, non-randomized, single-centre study comparing Dexcom G6® CBG level monitoring with the standard methods routinely used in this context. The standard blood glucose values were paired to the time corresponding values measured with Dexcom G6®. Agreement between the two methods and potential correlation in case of paracetamol use were calculated. Results: From May 2020 to August 2021, 36 out of 206 patients operated for isolated coronary artery bypass grafting were enrolled; 673 paired blood glucose level were analyzed. Global agreement (ρc) was 0.85 (95% C.I.: 0.84–0.86), intensive care unit agreement was 0.78 (95%C.I.: 0.74–0.82) and ward agreement was 0.91 (95%C.I.: 0.89–0.93). In the diabetic population, it was 0.87 (95%C.I.: 0.85–0.90). When paracetamol was used, the difference was 0.02 mmol/l (95%C.I.: 0.29–0.33). Conclusions: Dexcom G6® provides good blood glucose level accuracy in the postoperative context of cardiac surgery compared to the standard methods of measurements. The results are particularly reliable in the ward where the need for repeated capillary glucose measurements implies patient discomfort and time-consuming manipulations for the nursing staff.

Aneurysms of the Valsalva sinuses are rare among cardiovascular disorders, with an incidence rate of 0.15%. Most cases are accidentally diagnosed or constated postmortem. Usually, this type of pathology is asymptomatic and might go undetected for a long time before the aneurism erupts. Patients with larger coronary aneurysms often complain of from chest pain, shortness of breath, and arrhythmia. Another extremely rare cardiovascular pathology is the aneurysm of the subclavian artery, which has a reported rate of 0.13%. Smaller subclavian aneurysms have no clinical manifestation, whereas larger ones cause murmur, pulsation phenomenons, neuropathic pain and ischemia of the upper limb due to compression of the brachial plexus and major vessels. Herein, we report a rare case of a very large aneurisms involving all three coronary sinuses and the whole aortic root in combination with a bilateral giant subclavian aneurism. These findings were made during a routine cardiological examination and further hospitalizations of a 54-year-old woman with chest pain and high blood pressure complaints with known ankylosing spondylitis. Despite their rarity, aneurysms of the sinuses of Valsalva and subclavian arteries are of utmost clinical significance due to the life-threatening complications which might arise from their rupture. Furthermore, such aneurysms pose significant technical difficulties during angiographic procedures. Therefore, detailed knowledge of such pathologies is essential for correctly diagnosing and treating such patients.

The gold standard for the treatment of pathologies of the aortic arch remains the open surgical reconstruction of the affected segments. However, endovas-cular treatment options have emerged that eliminate the need for invasive open surgery. Several endograft devices – with fenestrations or branches for the supraaortic vessels – are currently available to address different pathologies and anatomical variations. Parallel-graft techniques and in situ fenestrations expand the treatment options for emergent cases. In this selective review of the literature of 2020 and 2021, we summarize the current chances and challenges of endovascular aortic repair.

Background: Acute aortic dissection is a life-threatening condition that requires urgent surgical treatment. The frozen elephant trunk (FET) technique, including the Thoraflex hybrid prosthesis, has emerged as an effective strategy for treating complex aortic pathologies. With the widespread application of the FET technique, it continues to evolve, aiming to simplify procedures and reduce complications. These advancements provide improved outcomes and help save lives in patients with acute aortic dissection. Methods: For this review, PubMed databases were utilized from inception to March 2023. A descriptive approach was employed to identify and present the evidence regarding the application of the FET technique in acute settings and its clinical implications on the postoperative course. Results: In the reviewed studies, FET was a commonly used treatment approach for acute type A aortic dissection. A comprehensive analysis of 12 studies, comprising over 4056 FET procedures, revealed varying rates of early mortality (up to 21.1%), perioperative stroke (ranging from 2.7 to 18.0%), and spinal cord ischemia (ranging from 0 to 8.2%). During the follow-up period, which ranged from 6 to 108 months, the mortality rate was reported to be as high as 38%. Conclusions: The surgical management of acute aortic dissection remains challenging, but FET has shown promising results. Experienced teams have achieved acceptable in-hospital mortality and stroke rates, along with a lower risk of spinal cord injury compared to conventional repair. Furthermore, the FET technique has demonstrated positive alterations in the structure of the distal aorta, potentially improving long-term survival and reducing the necessity for future procedures.

A proximal scallop design allows aortic arch repair without complex endovascular manipulation in the aortic arch. The aim was to assess the safety and efficacy at one year of the Relay proximal scallop stent graft. A prospective multicentre study evaluated consecutive patients treated with the Relay proximal scallop stent graft in 10 French aortic centres. All consecutive patients eligible for elective thoracic endovascular repair with proximal scallop in the 10 participating centres between January 2015 and July 2018 were included. Primary endpoints were 30 day mortality, stroke, and spinal cord ischaemia (SCI) rates. Outcomes including safety and efficacy, technical and clinical success, all cause death, neurological events, vessel patency, and device specific complications were analysed. Survival and survival without severe complications were estimated using Kaplan–Meier estimates. Ten aortic centres treated 40 patients for thoracic aortic aneurysm (45%), penetrating atherosclerotic aneurysm (30%), and dissection (25%). Half of the procedures (50%) targeted zone 0 of the aortic arch (zone 0 in 17.5% and zones 0/1 in 32.5%), 37.5% targeted zone 2 (35% zone 2 alone; 2.5% zones 1/2), and 15% targeted zone 1 (12.5% zone 1 alone). Median follow up was one year. Thirty day mortality, stroke, and SCI rates were 10%, 5%, and 0% respectively. Primary technical success was 95%. Type Ia, Ib, and III endoleaks rates were 5.4%, 0%, and 0% respectively at one month. The overall mortality rate at one year was 17.5%. Aneurysm expansion was > 5 mm in one case at one year associated with type Ia endoleak (3%). There was no supra-aortic trunk thrombosis, one (2%) graft kink, and no migration. One year outcomes showed that the Relay proximal scallop stent graft is an acceptable answer to thoracic aortic disease to deal with short proximal landing zones. [ABSTRACT FROM AUTHOR]

Key Clinical Message Acute aortic dissection in unusual/rare circumstances may become chronic and multi lumen. A high clinical acumen, examination and investigations in the acute setting, may help reduce late/misdiagnosis and complications in low resource settings.

BackgroundDespite the association of physical activity with improved cardiovascular outcomes and the association of high coronary artery calcification (CAC) scores with poor prognosis, elite endurance athletes have increased CAC. Yet, they nevertheless have better cardiovascular survival. We hypothesized that exercise may transform vascular calcium deposits to a more stable morphology.MethodsTo test this, hyperlipidemic mice (Apoe-/-) with baseline aortic calcification were separated into 2 groups (n = 9/group) with control mice allowed to move ad-lib while the exercise group underwent a progressive treadmill regimen for 9 weeks. All mice underwent blood collections and in vivo 18F-NaF μPET/μCT imaging both at the start and end of the exercise regimen. At euthanasia, aortic root specimens were obtained for histomorphometry.ResultsResults showed that, while aortic calcification progressed similarly in both groups based on µCT, the fold change in 18F-NaF density was significantly less in the exercise group. Histomorphometric analysis of the aortic root calcium deposits showed that the exercised mice had a lower mineral surface area index than the control group. The exercise regimen also raised serum PTH levels twofold.ConclusionThese findings suggest that weeks-long progressive exercise alters the microarchitecture of atherosclerotic calcium deposits by reducing mineral surface growth, potentially favoring plaque stability.

Abstract Background Total knee replacement is a major orthopedic procedure for severe, painful, and mobility-limiting knee arthritis. Aortic valve stenosis is the most frequent valvular heart disease and the most commonly performed valvular procedure. Stenosis of the valve may lead to left ventricular hypertrophy, ventricular dysfunction, myocardial ischemia, and a state of fixed cardiac output. Changes in hemodynamic parameters such as hypotension and bradycardia in patients with carotid artery stenosis may lead to cerebrovascular accidents, especially during anesthesia. Case presentation A 76-year-old woman with a 6-year history of bilateral knee pain. The pain was dull, aching, and severe in intensity, and it prevented her from sleeping despite optimal analgesics. A general physical examination revealed an elderly, frail woman in mild respiratory distress. She had bilateral small-volume radial pulses, positive hepatojugular reflux, and heart sounds of S1, S2, and S4 with an ejection systolic murmur, and carotid bruits were heard bilaterally. Epidural anesthesia was done by injection of 2.5 mL of 0.5% plain bupivacaine in aliquots every 5 min until the level of the block reached the suprapubic region (titrated segmental epidural anesthesia). The patient was not preloaded with intravenous fluid prior to the establishment of epidural anesthesia, and the epidural anesthesia-induced hypotension that may ensue was managed with intraoperative dopamine infusion at 5 µg/kg/min. Conclusions Titrated segmental epidural anesthesia with intraoperative infusion of low-dose dopamine reduces the perioperative risk of myocardial infarction, cerebrovascular accident, and neurocognitive deficit in a patient with severe aortic stenosis and severe bilateral carotid stenosis.

Open in new tab Download slide OBJECTIVES Acute aortic syndromes are associated with poor outcomes, despite diagnostic and therapeutic advances. We analysed trends in volumes and outcomes from 2000 to 2021. METHODS The study population includes 494 type A acute aortic syndromes (TAAAS) (54.2%) and 418 type B acute aortic syndromes (TBAAS) (45.8%). Primary outcomes were in-hospital mortality, long-term survival and freedom from aortic reoperation. RESULTS Regardless the type of acute aortic syndrome, patient volumes increased over time. Patients with TBAAS were older, more likely to have comorbid conditions and previous cardiac surgery (P  < 0.001), while cerebrovascular accidents were more frequent in TAAAS (P  < 0.05). Among TAAAS, 143 (28.9%) required total arch and 351 (71.1%) hemiarch replacement. TBAAS management was medical therapy in 182 (43.5%), endovascular in 198 (47.4%) and surgical in 38 (9.1%) cases. Overall in-hospital mortality was 14.6% [18.2% in TAAAS (95% confidence interval (CI) 14.4–21.2%) vs 10.7% in TBAAS (95% CI 7.8%–13.7%); P  = 0.0027]. After propensity score adjustment, in-hospital mortality exhibited a significantly decreasing trend from 2000 to 2021 (P  < 0.001) in TAAAS and TBAAS. 1-, 5- and 10-year survival was 74.2%, 62.2% and 45.5% in TAAAS and 75.4%, 60.7% and 41.0% in TBAAS (P  = 0.975), with no differences among treatment strategies. The adjusted cumulative reoperation risk at 10 years was more than two-fold in TBAAS versus TAAAS (9.5% vs 20.5%, hazard ratio (HR) = 2.30, 95% I 1.31–4.04). CONCLUSIONS In the last decades, better patient triage and surgical/endovascular techniques led to substantial improvements in the management of acute aortic syndrome, with reduction in early mortality and reoperation rate. However, long-term mortality is still >50%. [ABSTRACT FROM AUTHOR]

A 47-year-old man with a history of hypertension was found to have a prominent aortic knob on routine chest X-ray and was referred to our hospital. Enhanced computed tomography angiography showed severe flexion at the proximal descending aorta with chronic type B dissection localized to the flexion region. Graft replacement of the distal aortic arch was performed. Surgical management of chronic pseudocoarctation dissection is sparsely reported in the literature because of its rare occurrence. We present an operative case of a patient with chronic dissection of distal aortic arch pseudocoarctation. [ABSTRACT FROM AUTHOR]

Despite advancements in surgical and postoperative management, spinal cord injury has been a persistent complication of both open and endovascular repair of thoracoabdominal and descending thoracic aortic aneurysm. Spinal cord injury can be explained with an ischemia-infarction model which results in local edema of the spinal cord, damaging its structure and leading to reversible or irreversible loss of its function. Perfusion of the spinal cord during aortic procedures can be enhanced by several adjuncts which have been described with a broad variety of evidence in their support. These adjuncts include systemic hypothermia, cerebrospinal fluid drainage, extracorporeal circulation and distal aortic perfusion, segmental arteries reimplantation, left subclavian artery revascularization, and staged aortic repair. The Authors here reviewed and discussed the role of such adjuncts in preventing spinal cord injury from occurring, pinpointing current evidence and outlining future perspectives.

Background: Endovascular aortic arch repair (EAR) has emerged as an alternative to open surgical repair. A growing interest in endovascular repair techniques for aortic arch aneurysms and dissection has been met with a focus on the clinical efficacy of EAR devices. We present multicentre comparative data on the clinical outcomes associated with EAR using the double- and triple-branched configurations of the RELAY™ (Terumo Aortic, Scotland, UK) endograft. Methods: Multicentre data on EAR procedures, carried out from January 2019 to January 2022, using the double- and triple-branched RELAY™ endograft were collected prospectively. Follow-up data were collected at 30 days, 6 months, 12 months, and 24 months postoperative. Retrospective descriptive analysis, logistic regression, and Kaplan–Meier analysis were carried out on procedural and follow-up data. Results: A total of 131 patients were included in the series. In total, 103 and 28 patients were treated with the double-branched and triple-branched RELAY™ endograft, respectively. Over the 24-month follow-up period, zero mortality, cases of stroke, or reinterventions were recorded in the triple-branched group. Four mortalities, 19 disabling strokes, and 50 reinterventions were recorded in the double-branched group within 30 postoperative days. Target vessel patency was maintained in all patients in the triple-branched group, while vessel patency was maintained in 74.0% of patients in the double-branched group. Conclusion: Outcomes associated with the triple-branched group are consistent with those reported in the literature. Our data suggest that EAR with the RELAY™ endograft is associated with favourable clinical outcomes and clinical efficacy. Further comparative research into EAR devices is needed.

A 67-year-old female patient presented with abdominal pain with a recent diagnosis of paroxysmal atrial fibrillation. Computed tomography (CT) of the abdomen demonstrated a filling defect concerning for an aortic thrombus. Point of care ultrasound (POCUS) confirmed a mobile thrombus in the proximal abdominal aorta in close proximity to several major arterial branches, leading to urgent surgical consultation due to a concern for mesenteric and end-organ ischemia. POCUS played a role in determining patient management in this novel case, and the patient was anticoagulated and ultimately discharged from the hospital.

Purpose: The purpose of this study was to determine the safety and accuracy of aortic and periaortic computed tomography (CT)-guided percutaneous core needle biopsy performed at a single center over 12 years. Materials and methods: A retrospective review was conducted of cases performed between February 2010 and August 2022 in which the biopsied region was in direct contact with the aorta or great vessels including the pericardium and common iliac arteries. Clinical notes were reviewed for any early or delayed complications following the procedure, which if present were graded using the National Institute of Health's Common Terminology Criteria for Adverse Events, version 5.0. Pathology results were compared to subsequent outside biopsy results or follow-up surgical pathology, if available, as well as subsequent clinical decision making and/or clinical course, to determine concordance. Sensitivity, specificity, predictive value, and accuracy (indicative of diagnostic yield) were calculated. Results: 32 core needle biopsies were reviewed from 30 patients (average lesion longest diameter 3.1 cm, range 0.5–10.9 cm; average needle proximity to the vessel endothelium or deep side of the pericardium 1.0 cm, range 0.3–1.8 cm). Complications occurred in 46.9% of cases (15/32), 93.3% (14/15) of which were minor and included small amounts of bleeding or pain. One patient developed a small nonemergent pneumothorax. Of biopsies obtained, 96.9% provided adequate tissue for diagnosis (31/32). When evaluating concordance between pathological and final diagnosis, sensitivity was 94.7% and specificity was 83.3%; positive and negative predictive value were 90.0% and 90.9%, respectively. Accuracy (diagnostic yield) of biopsy was 90.3%. Conclusion: CT-guided percutaneous aortic and periaortic core needle biopsies are safe and efficacious procedures with high diagnostic yield.

All patients underwent valvular surgical procedures including mitral valve replacement (MVR), aortic valve replacement (AVR), AVR with coronary artery bypass grafting (CABG), MVR with CABG, or AVR and MVR with or without CABG. This study included patients who underwent surgery between 2002 and 2017.Results: Three hundred and forty-six patients were included in this study. The mean patient age was 51.6± 16.1 years; 37% of the patients underwent AVR, 28% underwent MVR, and 13% underwent a combination of MVR with AVR, AVR with CABG in 6%, and MVR with CABG in 10%. The operative mortality rate was 5.8% (n=20). Univariate analysis revealed that the predictors of mortality included age (P < 0.001), body mass index (BMI) (P = 0.003), type of surgery performed (P = 0.007), hypertension (P = 0.005), emergent surgeries (P = 0.018), left atrial diameter (P = 0.003), cross-clamp time greater than 90 minutes (P = 0.007), postoperative acute kidney injury (AKI) (P = 0.044), postoperative stroke (P = 0.049), and surgical site infection (P = 0.047). Multivariate analysis revealed that predictors of mortality included age (P = 0.028, AOR=10.6), BMI (P = 0.003, AOR=3.12), re-exploration (P = 0.006, AOR=8.38), length of intensive care unit stay (P ≤ 0.002, AOR=4.55), and left atrial diameter (P = 0.003, AOR=10.64).Conclusion: Enlargement of the left atrium has been studied extensively as a predictor of mortality and morbidity in different clinical situations, to the extent that some authors suggest adding it to risk stratification models. In this study, left atrial size > 4 cm was found to strongly predict mortality after rheumatic heart valve surgery.Keywords: valve surgery, mortality, mitral, aortic, left atrial size

Blunt thoracic aortic injury (BTAI) is a potentially fatal condition that needs prompt recognition and expedited management. Clinical manifestations of BTAI are not straight forwarding and may be misdiagnosed. The grade of aortic injury is an important determinant of perioperative mortality and morbidity, as well as the indication of treatment, along with the presence of concomitant lesions of other involved organs. The mainstay of treatment nowadays for hemodynamically stable patients who survive the trauma scene is represented by delayed endovascular repair whenever anatomically and clinically feasible. Endovascular repair, in fact, is burdened by lower perioperative mortality and morbidity rates if compared to open surgical repair, but concerns remain about the need for long-term surveillance and radiation exposure in patients who are at a younger age than patients treated for the aneurysmal disease. The aim of the paper is to provide an update on the diagnostic modalities and strategies of treatment for patients affected by BTAI. [ABSTRACT FROM AUTHOR]

Multimorbidity, the coexistence of multiple health conditions in an individual, has emerged as one of the greatest challenges facing health services, and this crisis is partly driven by the aging population. Aging is associated with increased aortic stiffness (AoStiff), which in turn is linked with several morbidities frequently affecting and having disastrous consequences for the elderly. These include hypertension, ischemic heart disease, heart failure, atrial fibrillation, chronic kidney disease, anemia, ischemic stroke, and dementia. Two or more of these disorders (multimorbidity) often coexist in the same elderly patient and the specific multimorbidity pattern depends on several factors including sex, ethnicity, common morbidity routes, morbidity interactions, and genomics. Regular exercise, salt restriction, statins in patients at high atherosclerotic risk, and stringent blood pressure control are interventions that delay progression of AoStiff and most likely decrease multimorbidity in the elderly.

The current conventional open TAAA repairs are performed by select centers around the world with good outcomes. However, lesser experienced centers often encounter difficulties in replicating similar results of open TAAA surgeries. The modified branch-first open repair of TAAA has shown to be effective in minimizing visceral and renal complications by providing continuous visceral blood flow throughout the procedure. By debranching the visceral vessels first, we can perform this complex aortic procedure in a more controlled manner as compared to the traditional clamp and sew technique which requires speed, precision and experience. The entire repair can be performed on beating heart by deriving native blood flow via a closed circuit or a modification of the left heart bypass and continuously perfusing the abdominal viscera, thus avoiding cardiopulmonary bypass or deep hypothermic circulatory arrest which helps minimize bleeding and overall morbidity associated with extensive TAA surgeries. Adequate pre-operative planning is imperative to prevent spinal cord complications and intra-operative emergencies. [ABSTRACT FROM AUTHOR]

A 72 year-male patient with infrarenal abdominal aortic aneurysms (AAA) of 5.7 cm along with 4 cm right common iliac artery aneurysm presented for repair. The patient had a history of COPD and CAD. After obtaining a medical and cardiac work-up, we elected to pursue an endovascular repair. The central line length as measured from the lowest renal artery to the origin of right internal iliac artery was 157 mm. Therefore, a main aortic device (RLT311413, 31 mm X 14 mm X 13 cm) was deployed via left groin access. Next, a bell-bottom iliac graft (PLC201000, 20 mm X 9.5 cm) to right common iliac artery aneurysm was placed before deploying a right-sided Gore® Excluder® Iliac Branch Endoprosthesis (IBE) (W. L. Gore and Associates, AZ, USA). A through-and-through wire above the follow divider was achieved, and then a 12 Fr. Gore DrySeal Sheath® (W.L. Gore and Associates, AZ, USA) was telescoped without manipulation of the main device. A Gore® Viabahn® VBX balloon (11 mm X 79 mm, W. L. Gore and Associates, AZ, USA) was extended to the right internal iliac artery, and then a right external iliac stent was inserted via right groin access. The final angiogram showed appropriate stents placed without endoleak. The patient was discharged home on postoperative day 1 without any complications.

Access is an imperative component of endovascular aneurysm repair. The common femoral artery is the most common access site, and the artery is traditionally exposed via open cutdown or, more commonly, via percutaneous access. Access consideration is not limited to femoral arteries only but also includes both the external and the common iliac arteries. We report the case of a 72-year-old female patient who presented with a contained ruptured abdominal aortic aneurysm with small-diameter left common femoral (4 mm) and external iliac (3 mm) arteries. We used an innovative technique without the need for cutdown or the use of an iliac conduit. Balloon expandable covered stents were used that were compatible (in size) to an 8F sheath. The stents were postdilated to a larger diameter to achieve the appropriate seal at the flow divider. Endovascular exclusion of the aneurysm was achieved, and the patient was discharged home on postoperative day 2. At the 6-week office follow-up visit, the abdominal examination findings were benign, and she had positive signals in both feet. Aortic duplex ultrasound showed patent stents and no endoleak.

An elderly woman presented a year after undergoing endovascular repair of her infrarenal aortic aneurysm (IRAA) with abdominal pain and hypotension. Imaging revealed a ruptured IRAA, and this was managed with banding of the aorta to correct the Type-1a endoleak and tranexamic acid postoperative. We share details and a brief review of the literature.

The European Association for Cardiothoracic Surgery (EACTS) and the American Society of Thoracic Surgeons (STS) have released new guidelines for the diagnosis and treatment of aortic diseases. These guidelines, which come ten years after the previous release, cover various aspects of aortic diseases and are summarized in 36 tables of recommendations. The guidelines emphasize the recognition of the aorta as an organ in its own right and recommend endovascular treatment as the first-line intervention for many aortic pathologies. The guidelines also highlight the importance of wide consensus among professionals and advocate for a lower threshold for elective surgery on the ascending aorta. However, it is important to note that the level of evidence supporting most of the recommendations is categorized as 'level C', indicating a reliance on small cohorts of patients, retrospective analyses, and expert consensus. The guidelines also stress the need for more research in various areas of aortic disease treatment. [Extracted from the article]

In this study, we report our local experience of type A aortic dissections in patients with cerebral malperfusion treated with carotid stenting before or after aortic surgery, and present a systematic literature review on these patients treated either with carotid stenting (CS) before or after aortic surgery (AS) or with aortic and carotid surgery alone (ACS). We report on patients treated in our center with carotid stenting for brain hemodynamic injury of carotid origin caused by type A dissection since 2018, and a systematic review was conducted in PubMed for articles published from 1990 to 2021. Out of 5307 articles, 19 articles could be included with a total of 80 patients analyzed: 9 from our center, 29 patients from case reports, and 51 patients from two retrospective cohorts. In total, 8 patients were treated by stenting first, 72 by surgery first, and 7 by stenting after surgery. The mean age; initial NIHSS score; time from symptom onset to treatment; post-treatment clinical improvement; post-treatment clinical worsening; mortality rate; follow-up duration; and follow-up mRS were, respectively, for each group (local cohort, CS before AS, ACS, CS after AS): 71.2 ± 5.3 yo, 65.5 ± 11.0 yo; 65.3 ± 13.1 yo, 68.7 ± 5.8 yo; 4 ± 8.4, 11.3 ± 8.5, 14.3 ± 8.0, 0; 11.8 ± 14.3 h, 21 ± 39.3 h, 13.6 ± 17.8 h, 13 ± 17.2 h; 56%, 71%, 86%, 57%; 11%, 28%, 0%, 14%; 25%, 12.3%, 14%, 33%; 5.25 ± 2.9 months, 54 months, 6.8 ± 3.8 months, 14 ± 14.4 months; 1 ± 1; 0.25 ± 0.5, 1.3 ± 0.8, 0.68 ± 0.6. Preoperative carotid stenting for hemodynamic cerebral malperfusion by true lumen compression appears to be feasible, and could be effective and safe, although there is still a lack of evidence due to the absence of comparative statistical analysis. The literature, albeit growing, is still limited, and prospective comparative studies are needed. [ABSTRACT FROM AUTHOR]

Purpose: To examine the demographic characteristics, clinical symptoms, investigation modalities, travel time, type of surgical procedures and survival time of patients with acute aortic dissection of DeBakey I type. Methods: Retrospective analysis of patients with acute aortic dissection operated on at the Department of Cardiac Surgery SÚSCCH, a. s. in Banská Bystrica in the period 2004 – 2020. Results: In total, 280 patients were operated on for acute aortic syndrome, 260 of them (age 61.4 ± 5.6 years, male 69%) were operated on for dissection of DeBakey type I. Arterial hypertension, smoking and atherosclerosis were the most common risk factors, 80%, 28.5% and 18.1% respectively. Transport time was gradually shortened, from 20.4 h (2004 – 2012) to 15.8 h (2013 – 2019) and up to 9.3 h (2020). The most common surgical procedure was supracoronary ascending aorta replacement (70%). Operation mortality rate was 23% and 30-day mortality after cardiac surgery was 42%. Conclusions: Patients with acute aortic dissection had typical cardio-vascular risk factors. Patients´ transport time was shortened by more than 2 times during the study period. Despite long-term experience, however, acute aortic dissection represents a life-threatening condition for the patient. [ABSTRACT FROM AUTHOR]

In situ fenestration of stent-graft represents a potential option for the treatment of aortic diseases in patients unsuitable for standard endovascular repair. The best fenestration strategy to restore perfusion of collateral vessels after their coverage by an endograft depends mainly on the anatomical area. Several tools are employed as fenestration devices, including needles, radiofrequency probes, and laser systems, used in conjunction with other instrumentation to provide enough support and stability during the procedure. In this systematic review, the approaches to reach the correct fenestration site both in human, animal, and in in vitro environments are described and discussed, highlighting advantages and limitations. Both commercial and dedicated solutions for the intraoperative modification of the fabric material are reported as well. The clinical interest in this procedure has so far encouraged researchers to develop and refine both methods and tools to solve the current limitations of this technique, intending to extend the indications for endovascular treatment to a broader range of patients.

Surgery for acute type A aortic dissection remains challenging with considerable mortality and morbidity despite the remarkable advances in this field. Particularly, surgical outcomes of acute type A aortic dissection are known to be associated with the hospital volume. The optimal cerebral protective method and extent of surgery have been long-standing controversies in acute type A aortic dissection surgery. Given that data from randomized trial are not available and future trials are also unrealistic, observational data based on large registry or meta-analyses may alternatively provide reliable and reasonable evidence. With regard to neuroprotective methods for arch repair, currently available observational data strongly suggest that there are no overt superiority among unilateral-antegrade cerebral perfusion, bilateral-antegrade cerebral perfusion, and retrograde cerebral perfusion, by which their availabilities are still open in real clinical practices depending on institutional preferences. When deciding the extent of arch repair in acute DeBakey type I aortic dissection, multiple factors should be considered altogether such as aortic anatomic characteristics as well as patient's risk profiles for optimizing early safety and late aortic longevity.

Aortic valve stenosis (AVS) is the most frequent valvular heart disease in industrialized countries, presenting with very high mortality if left untreated. While drug treatment can sometimes alleviate symptoms, it fails to stop progression or cure the underlying disease. Until the first decade of this millennium, surgical aortic valve replacement (SAVR) remained the only available therapy option with a positive impact on mortality and morbidity. Even though several studies reported highly positive effects of SAVR regarding the improved quality of life and better physical performance, SAVR remained an intervention that, due to its remarkable complexity and the need for heart-lung machine and cardioplegia, was limited by the patients' comorbid profile. While unsatisfying hemodynamic results after transcatheter aortic balloon valvuloplasty in high-risk surgical patients limited its adoption as an alternative treatment, it provided the impetus for further interventional approaches to the therapy of AVS. This review considers the invention and development of transcatheter aortic valve implantation (TAVI), which established itself as a catheter-based, minimally invasive procedure over the past decade, and has become an equivalent treatment method for high-risk surgical patients. For that matter, early TAVI concepts, their amendments, and the associated pioneers are recognized for paving the way to a revolutionary diversification in AVS treatment. [ABSTRACT FROM AUTHOR]

Abstract Background Excellent partial upper sternotomy outcomes have been reported for patients undergoing aortic surgery, but whether this approach is particularly beneficial to obese patients remains to be established. This study was developed to explore the outcomes of aortic surgical procedures conducted via a partial upper sternotomy or a full median sternotomy approach in obese patients. Methods We retrospectively examined consecutive acute type A aortic dissection patients who underwent aortic surgery in our hospital between January 2015 to January 2021. Patients were divided into two groups based on body mass index: ‘non-obese’ and ‘obese’. We then further stratified patients in the obese and non-obese groups into partial upper sternotomy and full median sternotomy groups, with outcomes between these two sternotomy groups then being compared within and between these two body mass index groups. Results In total, records for 493 patients that had undergone aortic surgery were retrospectively reviewed, leading to the identification of 158 consecutive obese patients and 335 non-obese patients. Overall, 88 and 70 obese patients underwent full median sternotomy and partial upper sternotomy, respectively, while 180 and 155 non-obese patients underwent these respective procedures. There were no differences between the full median sternotomy and partial upper sternotomy groups within either BMI cohort with respect to preoperative baseline indicators and postoperative complications. Among non-obese individuals, the partial upper sternotomy approach was associated with reduced ventilation time (P = 0.003), shorter intensive care unit stay (P = 0.017), shorter duration of hospitalization (P = 0.001), and decreased transfusion requirements (Packed red blood cells: P

ObjectivesIsolated abdominal aortic dissection (IAAD) is extremely rare, with its optimal treatment and intervention timing remaining poorly understood. We aimed to study the natural history of IAAD and facilitate better clinical decision.MethodsConsecutive patients admitted to our institution from January 2016 to April 2021 were enrolled and followed up prospectively. All-cause death was taken as the primary endpoint.ResultsA total of 68 patients with IAAD were included. The mean age at presentation was 61.2 ± 14.8 (Range: 26.0, 93.0) years and 55 (80.9%) were male. A total of 38 (55.9%) patients were treated conservatively, 27 (39.7%) received endovascular aneurysm repair (EVAR), and 3 (4.4%) underwent open surgery. After a mean follow-up of 2.4 years (Range: 0.1, 5.5), 9 (13.2%) patients died, 8 of whom (21.0%) were treated conservatively and 1 EVAR (3.7%). Compared with EVAR/open surgery, patient treated conservatively had a much worse survival (p = 0.043). There was no significant difference between different IAAD aortic sizes regarding mortality (p = 0.220). Patients with completely thrombosed false lumen fared improved survival rate, followed by partial thrombosis and patency, respectively, although not significantly (p = 0.190). No significant difference was observed between male and female concerning survival rate (p = 0.970). Patients without symptoms had a significantly improved survival (p = 0.048).ConclusionOn the basis of patients’ preference and surgeons’ experience, a more aggressive treatment regimen for IAAD should be considered, with EVAR being the first choice, especially for those with persistent symptoms and patent false lumen, regardless of sex, age, or aortic size.

Endovascular aneurysm repair has dramatically changed the management of abdominal aortic aneurysms as an alternative to open repair. However, complications can occur, including stent graft migration, kinking, and occlusion, leading to compromise of the excluded aneurysm walls and acute limb ischemia. In the present report, we have described a case of migration and kinking of an abdominal aortic stent graft in the main body that led to occlusion of the abdominal aorta and bilateral acute limb ischemia. The patient required emergent explantation of the stent graft and open repair of the abdominal aneurysm with a rifampin-soaked Dacron graft, which achieved a favorable outcome.
