Malignancy-Induced Functional Tricuspid Obstruction Complicated by Cardiopulmonary Collapse Treated Using Combination VA-ECMO and AngioVac

April 12, 2025 No Comments

This clinical case report details the rescue of a critically ill patient with malignancy-induced tricuspid obstruction and cardiopulmonary collapse. A large intracardiac mass was removed using vacuum-assisted aspiration thrombectomy (AngioVac), combined with venoarterial extracorporeal membrane oxygenation (VA-ECMO). This approach enabled hemodynamic stabilization and definitive diagnosis of diffuse large B-cell lymphoma, followed by successful oncologic treatment.

Survival Analysis of Minimally Invasive Mitral Valve Surgery Versus Conventional Median Sternotomy in the United States

April 11, 2025 No Comments

This retrospective cohort study compares survival outcomes and surgical efficiency between minimally invasive mitral valve surgery (MiMVS) via mini-thoracotomy and conventional sternotomy. Among 422 elective cases, MiMVS was associated with shorter hospital stays, less postoperative bleeding, and shorter operative times. Although no significant survival difference was found, mitral valve replacement showed higher mortality risk than repair.

5-Year Outcomes After Transcatheter or Surgical Aortic Valve Replacement in Low-Risk Patients With Aortic Stenosis

April 5, 2025 No Comments

This study presents 5-year outcomes from the Evolut Low Risk trial, comparing transcatheter aortic valve replacement (TAVR) with surgery in low-risk patients with severe aortic stenosis. Results showed no significant difference in all-cause mortality or disabling stroke between the groups, affirming TAVR as a noninferior option. Both treatments maintained excellent valve performance, similar quality-of-life improvements, and low reintervention rates.

Cardiopulmonary Bypass and Cross-Clamping Times in Aortic Valve Replacement Surgery by Ministernotomy with Sutureless Prosthesis Implantation Compared to Conventional Prosthesis: A Cross-Sectional Study

March 21, 2025 No Comments

This study compares cardiopulmonary bypass (CPB) and cross-clamping times in aortic valve replacement surgeries performed via ministernotomy using either sutureless PERCEVAL® or conventional bioprostheses. Among 93 patients, both techniques showed similar outcomes regarding CPB and cross-clamping times, hospital stays, and early postoperative complications. Echocardiographic results improved postoperatively in both groups.

Buckberg vs. Del Nido in Isolated Aortic Valve Replacement: A Prospective, Two-Center, Randomized Trial

March 16, 2025 No Comments

This study compares Buckberg (BS) and Del Nido (DNS) cardioplegia in isolated aortic valve replacement (AVR) through a two-center randomized trial with 311 patients. While postoperative creatine kinase and troponin levels showed no significant differences, the DNS group had better intraoperative glycemic control, higher spontaneous rhythm rates, and fewer cases of ventricular fibrillation requiring defibrillation. The study supports DNS as a viable alternative with workflow advantages.

Assistance from a Mixing Zone Model to Perform Aortic Femoral Perfusion Strategy with Severe Atherosclerotic and Artheromic Aortic Disease for Endoscopic Minimally Invasive Redo Mitral Valve Repair

March 15, 2025 No Comments

This study explores a novel perfusion strategy for minimally invasive redo mitral valve surgery in patients with severe atherosclerotic and artheromic aortic disease. Using a combination of antegrade and retrograde perfusion, the study evaluates the mixing zone during cardiopulmonary bypass (CPB) to optimize outcomes. A case study demonstrates the effectiveness of this approach, with no postoperative cerebral complications. Findings suggest that adjusting cannulation sizes can improve perfusion safety.

Is Surgery for Congenital Heart Defects in Neonates, Infants, and Children More Challenging and Demanding Than Surgery for Acquired Heart Defects in Adults?

March 5, 2025 No Comments

Pediatric cardiac surgery presents unique challenges due to the complexity of congenital heart defects (CHD), requiring highly specialized techniques, individualized interventions, and long-term patient care. Unlike adult cardiac surgery, which addresses standardized conditions, CHD surgery demands precision, adaptability, and multidisciplinary expertise. Limited cardiovascular reserves in younger patients increase surgical risks. Addressing global disparities in pediatric cardiac care is crucial for improving outcomes.

The Value of Off-Pump Coronary Artery Bypass Grafting in Surgery for Combined Valvular and Coronary Heart Disease

December 8, 2024 No Comments

This study explores the benefits of off-pump coronary artery bypass grafting (OPCABG) in surgeries combining valve and coronary interventions. Among 884 patients, the OPCABG group showed reduced incidences of postoperative atrial fibrillation (29.5% vs. 39.5%) and acute kidney injury (14.5% vs. 21.2%) compared to on-pump CABG. No differences in mortality or stroke rates were observed. The results suggest OPCABG is a safe and effective approach for improved short-term outcomes in complex cardiac surgeries.

A Historical Perspective and Update on Robotic Mitral Valve Surgery

November 19, 2024 No Comments

This study reviews the evolution of minimally invasive mitral valve repair, emphasizing the use of robotic platforms from 2005 to 2023. Analyzing 1,412 robotic repairs, it highlights improvements in outcomes, including reduced cross-clamp and bypass times and high repair durability. Degenerative disease was the most common indication, with 98.1% repair success and a ten-year survival rate exceeding 91%. The findings support robotic surgery as a durable, teachable, and safe option for mitral valve repair.

New Approach to the Mitral Valve Through the Left Anterior Minithoracotomy for Combined Valve and Coronary Surgical Procedures

June 8, 2024 No Comments

A new technique for accessing the mitral valve via the left anterior minithoracotomy has been developed for patients requiring both mitral valve surgery and coronary artery bypass grafting. From October 2020 to September 2022, 24 patients underwent this procedure, which involved specialized exposure maneuvers and conventional surgical techniques. The approach proved successful with no need for conversion to sternotomy, no major complications, and no mortality within 30 days post-procedure.
