Valve-Sparing Versus Composite Graft Aortic Root Replacement in Acute Type A Aortic Dissection with Standardized Hemiarch Repair: A Propensity Score Matching Analysis

When a standardized hemiarch replacement was used, no significant differences in short- and long-term outcomes were observed between a valve-sparing procedure and composite graft replacement in patients undergoing surgical repair for ATAAD. Surgeons should opt for the surgical strategy they are most comfortable with. This study represents one of the few analyses comparing the David and Bentall techniques in ATAAD patients undergoing standardized hemiarch replacement. Despite its retrospective nature, it provides clinically relevant insights for surgical decision-making in emergency settings.
