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.

First Experiences with Automated Annular Suturing Device in Totally Endoscopic Aortic and Mitral Valve Replacement

June 4, 2024 No Comments

This study investigates the early clinical outcomes of using an automated annular suturing device, the RAM® device, in endoscopic minimally invasive aortic and mitral valve replacement surgeries. Conducted between September 2020 and June 2023, the study involved 66 patients with an average age of 61.8 years. The results showed no intraoperative complications, no paravalvular leaks, and zero 30-day and in-hospital mortality, indicating the procedure’s safety and effectiveness. Larger studies are recommended to further evaluate the device’s efficacy.

Comparative Analysis of Long-Term Outcomes in Valve-Sparing Aortic Root Reimplantation: Full Sternotomy versus Mini-Sternotomy Approach

May 16, 2024 No Comments

This study compares long-term outcomes between mini-sternotomy and full sternotomy approaches for valve-sparing aortic root reimplantation. The mini-sternotomy group had longer surgical times but similar in-hospital outcomes and shorter hospital stays compared to the full sternotomy group. Over a median follow-up of 5.5 years, survival rates were comparable, with no need for repeat interventions on the aortic valve. The mini-sternotomy approach shows promise for its potential advantages, including cosmetic outcomes.

Long-Term Impact of Cardiac Damage Following Transcatheter Aortic Valve Replacement

April 30, 2024 No Comments

This study explores the prognostic implications of changes in cardiac damage following transcatheter aortic valve replacement (TAVR). Analyzing 1,863 patients from the SwissTAVI Registry, researchers found significant variations in cardiac damage stages pre- and post-TAVR, affecting long-term survival. Nearly half of the patients experienced changes in cardiac stage, highlighting the importance of cardiac damage evaluation for predicting outcomes after TAVR.
