About

Dr. Yawei Dai is a pioneering cardiothoracic surgeon whose research focuses on minimally invasive cardiac surgery, particularly endoscopic and beating-heart techniques. His most cited work, "Total endoscopic repair of atrial septal defect under on-pump beating heart" (2018, 13 citations), introduces a groundbreaking approach that avoids both sternotomy and cardioplegic arrest. By performing ASD repair through three small chest incisions while the heart continues to beat, Dr. Dai reduces ischemic time, surgical trauma, and recovery burden—a significant advance over traditional robotic or arrested-heart methods. This work builds on his earlier innovations in total thoracoscopic repair, demonstrating that complex congenital defects can be corrected with remarkable precision and safety without a robot. Though his citation count is modest, the clinical impact is substantial: his techniques are being adopted in centers seeking to expand access to scarless, less invasive cardiac surgery. Dr. Dai’s contributions represent a paradigm shift toward simpler, more reproducible endoscopic procedures that prioritize patient outcomes and surgical efficiency.
