About

Zeng-Shan Ma is a pioneering cardiothoracic surgeon whose work has significantly advanced minimally invasive cardiac surgery. His primary research focuses on developing and refining totally thoracoscopic techniques for congenital heart defect repair, particularly ventricular septal defects (VSDs). Ma’s landmark study, "Totally thoracoscopic closure of ventricular septal defect without a robotically assisted surgical system: A summary of 119 cases" (2013), demonstrated that complex intracardiac repairs could be performed safely through small chest incisions without robotic assistance—a paradigm-shifting approach that reduces surgical trauma, scarring, and recovery time. This work, cited 18 times, established a reproducible methodology that has been adopted by centers worldwide. Beyond this signature contribution, Ma has explored novel thoracoscopic approaches for other congenital anomalies and atrial septal defects, consistently prioritizing patient outcomes and surgical innovation. His cumulative research, with over 100 publications, has helped democratize access to minimally invasive cardiac surgery, particularly in resource-limited settings where robotic systems are unavailable. Ma’s dedication to teaching and procedural standardization has made him a respected figure in cardiothoracic surgery, inspiring a new generation of surgeons to push the boundaries of what is possible through small incisions.
