Intimal sarcoma of the aortic valve and ascending aorta: a case report.

Background: Intimal sarcomas are rare tumors that typically affect the major vessels, such as the pulmonary artery and aorta, and are associated with a particularly poor prognosis. Intimal sarcomas found in the aorta are most commonly located in the abdominal section between the celiac artery and the iliac bifurcation. The descending aorta is involved in 30% of cases, while involvement of the ascending aorta is rare.

Introduction: There is a lack of evidence regarding the impact of donor blood transfusion on heart transplant (HT) outcomes. We sought to elucidate the influence of donor transfusion on HT outcomes using the national database.

Methods: From January 2004 to March 2023, donor transfusion information was available for 40 538 recipients for HT in the United Network for Organ Sharing (UNOS) database.

Pannus formation: a rare culprit of early bioprosthetic valve dysfunction-a case report.

Background: Early bioprosthetic valve dysfunction (BVD) due to pannus formation is uncommon in elderly patients, and only a limited number of cases have been reported.

Case Summary: An 84-year-old man presented with exertional dyspnoea 3 years after surgical aortic valve replacement (SAVR) with a 19 mm Epic™ valve (Abbott, Santa Clara, CA, USA). Transthoracic echocardiography demonstrated progressive BVD, and cardiac computed tomography (CT) revealed sub-aortic pannus formation.

Axillary artery access considerations in Impella 5.5 insertion: Insights from exclusive axillary approach for successful support.

Background: The Impella 5.5® is commonly inserted via the axillary artery (AX) in patients with cardiogenic shock. The right AX has traditionally been preferred to avoid crossing the aortic arch, and a minimum diameter of 7 mm has been recommended to accommodate the device (21 Fr).

Single-center experience of extended brain-death donor heart preservation with the organ care system.

Background: The Organ Care System (OCS) (Transmedics, Andover, MA) reduces cold ischemic time of donor hearts by producing a normothermic beating state during ex vivo perfusion, enabling extended ex situ intervals, which potentially increases donor pool. We aimed to compare outcomes in utilization of OCS and conventional cold storage technique.

Methods: Consecutive heart transplants following brain death at our institution between May 2022 and July 2023 were analyzed.

Strategy and Outcomes of Cardiac Surgery in Patients With Cirrhosis: Comprehensive Approach With Liver Transplant Program.

The Impact of Ipsilateral Implantable Cardioverter Defibrillator in Axillary Intra-Aortic Balloon Pump Support as Bridge to Heart Transplantation.

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.

Single patch technique for aortic annulus reconstruction in prosthetic valve endocarditis.

Aortic root reconstruction during aortic root replacement for a patient with prosthetic valve endocarditis and aortic root abscess can be a difficult procedure with many possible complications. In this video case report, we describe our novel technique using a single bovine pericardial patch that avoids deep stitches or external sutures to support the friable annulus. Compared with more standard methods, this approach has shorter cross-clamp and cardiopulmonary bypass times and is less demanding technically.

Impact of Left Ventricular Unloading on Outcome of Heart Transplant Bridging With Extracorporeal Membrane Oxygenation Support in New Allocation Policy.

Background: The new heart allocation policy places veno-arterial extracorporeal membrane oxygenation (VA-ECMO)-supported heart transplant (HT) candidates at the highest priority status. Despite increasing evidence supporting left ventricular (LV) unloading during VA-ECMO, the effect of LV unloading on transplant outcomes following bridging to HT with VA-ECMO remains unknown.

Methods And Results: From October 18, 2018 to March 21, 2023, 624 patients on VA-ECMO at the time of HT were identified in the United Network for Organ Sharing database and were divided into 2 groups: VA-ECMO alone (N=384) versus VA-ECMO with LV unloading (N=240).

Systematic review and network meta-analysis of various nadir temperature strategies for hypothermic circulatory arrest for aortic arch surgery.

Background: The optimal nadir temperature for hypothermic circulatory arrest during aortic arch surgery remains unclear. We aimed to assess and compare clinical outcomes of all three temperature strategies (deep, moderate, and mild hypothermia) using a network meta-analysis.

Methods: After literature search with MEDLINE and EMBASE through December 2021, studies comparing clinical outcomes with deep (<20°C), moderate (20-28°C), or mild (>28°C) hypothermic circulatory arrest were included.

Hybrid arch frozen elephant trunk repair for acute type A aortic dissection: Extra-anatomic subclavian reconstruction.

Acute type A aortic dissection is a life-threatening condition that confers significant early perioperative risk but is also associated with late aortic disease progression and the need for reintervention. Recent efforts to improve patient outcomes have focused on improving quality of care and extending treatment in the aortic root and arch to reduce late aortic events. The hybrid arch frozen elephant trunk technique facilitates a more aggressive distal aortic repair that may help mitigate the early and late deleterious effects of persistent false lumen perfusion.

Ross procedure for acute infective endocarditis.

Surgical treatment of infective endocarditis remains a challenge, with concerns of optimal prosthesis selection and risks of recurrent infection remaining paramount. The pulmonary autograft has unique features which may make it the ideal aortic valve substitute, especially in infectious endocarditis. We describe strategic considerations and technical details in performing a Ross procedure in a young patient with acute aortic valve endocarditis.

Safety and efficacy of cerebral embolic protection devices in patients undergoing transcatheter aortic valve replacement: a meta-analysis of in-hospital outcomes.

The evidence regarding the impact of cerebral embolic protection devices (EPDs) on outcomes following transcatheter aortic valve replacement (TAVR) is limited. The objective of this study was to evaluate in-hospital outcomes with the use of cerebral EPDs in TAVR. We performed a comprehensive EMBASE and PUBMED search to investigate randomized control studies or propensity score-matched retrospective studies which assessed patients undergoing TAVR with or without EPD up to April 2021.
