About
Dr. Katherine Sun is a pioneering cardiac surgeon whose research focuses on the hemodynamic outcomes of minimally invasive mitral valve repair, particularly in degenerative mitral regurgitation. Her work has advanced the understanding of transmitral pressure gradients (TMPGs) following robotic mitral valve repair with leaflet preservation techniques—a critical area where postoperative hemodynamic effects were previously poorly characterized. In her landmark 2024 study, Dr. Sun systematically investigated TMPGs in patients undergoing robotic MVr with leaflet preservation, providing the first detailed hemodynamic profile of this increasingly common surgical approach. Her findings have direct implications for surgical planning and postoperative management, helping to optimize patient selection and procedural techniques. With her work already cited in the emerging literature, Dr. Sun is establishing herself as a key voice in the evolution of robotic cardiac surgery, bridging the gap between technical innovation and measurable patient outcomes. Her research continues to shape best practices for preserving native valve function while minimizing invasive trauma.
