Abstract

Minimally invasive aortic valve replacement (AVR) combined with minimally invasive extracorporeal circulation (MiECC) and sutureless valve technology offers a promising strategy to reduce surgical trauma while maintaining procedural safety. We present two patients — a 68 year-old male and a 70-year-old female — with severe aortic stenosis and coronary artery disease who underwent minimally invasive AVR through a 7-cm right second intercostal thoracotomy using MiECC support, Del Nido cardioplegia, and Perceval™ Plus sutureless bioprosthetic valves. Cross-clamp times were 40 and 30 minutes respectively, and cardiopulmonary bypass times were 65 and 60 minutes. Intraoperative transesophageal echocardiography confirmed trace central aortic regurgitation with no paravalvular leakage in both cases. Both patients achieved early extubation within four hours and were discharged on postoperative days five and four respectively without complications. This integrated approach combining minimally invasive access, MiECC, sutureless valve technology, and single-dose cardioplegia is safe, reproducible, and associated with short operative times and rapid postoperative recovery in selected patients with severe aortic stenosis.
