Right Anterior versus Right Transaxillary Access for Minimally Invasive Aortic Valve Replacement: A Propensity Matched Competitive Analysis
This study compares the procedural and clinical outcomes of two minimally invasive techniques for aortic valve replacement: right anterior thoracotomy (RAT-AVR) and transaxillary access (MICLATS-AVR). With a cohort of 918 patients, after propensity score matching, both methods showed comparable major adverse cardio-cerebral events, cardiopulmonary bypass, and aortic cross-clamp times. However, MICLATS-AVR patients had a significantly shorter hospital stay and lower rates of postoperative wound issues, suggesting MICLATS-AVR as a safe, efficient, and feasible alternative for aortic valve replacement.
