About
Nan Cheng is a cardiac surgeon and researcher whose work sits at the forefront of minimally invasive and robotic cardiac surgery, with a particular focus on coronary artery bypass grafting (CABG) techniques. Cheng's research has meaningfully advanced the understanding and adoption of totally endoscopic coronary artery bypass (TECAB) and robotic-assisted surgical systems, helping to define the clinical learning curve and long-term patient outcomes for these complex procedures. Their 2014 study analyzing the learning curve for beating-heart, totally endoscopic CABG — now cited 34 times — provided critical insight into the procedural mastery required for safe implementation of this challenging technique. Subsequent work examining eleven-year outcomes of U-clip anastomosis versus conventional hand-sewn sutures in robotic CABG has further enriched the evidence base guiding surgical decision-making. More recently, Cheng has pushed into the realm of surgical simulation and training technology, contributing to the development of dynamic virtual simulation with real-time haptic feedback for robotic internal mammary artery harvesting — a forward-looking contribution to surgical education. Collectively, Cheng's body of work reflects a sustained commitment to refining robotic cardiac surgery and improving both patient outcomes and surgeon training.
