About

J. Onnasch is a pioneering cardiac surgeon whose work has fundamentally shaped the evolution of minimally invasive mitral valve surgery. His research focuses on transitioning from traditional open-heart procedures to progressively less invasive techniques, including Port-Access, video-assisted, and ultimately robot-assisted approaches. Onnasch’s major contribution lies in demonstrating the feasibility and safety of these advanced methods, systematically moving from 3D-video assisted solo surgery to remote telemanipulator-assisted repairs. His landmark paper, “The evolution of minimally invasive mitral valve surgery – 2 year experience” (1999, 156 citations), established a critical roadmap for the field, while his “Leipzig Experience with Robotic Valve Surgery” (2000, 84 citations) provided early, influential evidence for robotic assistance in valve repair. Through a large single-center series of over 230 patients, Onnasch proved that these innovative techniques could achieve excellent outcomes, reducing surgical trauma and recovery time. His work remains foundational for surgeons seeking to adopt and refine robotic mitral valve procedures, cementing his legacy as a key architect of modern, patient-friendly cardiac surgery.
