About

Torsten Doenst is a leading cardiac surgeon whose work centers on advancing minimally invasive and robotic techniques for mitral and tricuspid valve surgery. His major contributions include establishing the mini-mitral international registry (MMIR), a landmark dataset that has enabled large-scale, evidence-based analysis of outcomes in minimally invasive cardiac procedures. Through this registry, Doenst has demonstrated that while aortic cross-clamp times are longer in minimally invasive approaches, they correlate with mortality—a critical insight for surgical planning and patient safety. His provocative paper “Sizing for Mitral Annuloplasty: Where Does Science Stop and Voodoo Begin?” (80 citations) challenges conventional wisdom in valve repair, highlighting his willingness to question dogma. More recently, his work on endoscopic versus direct vision approaches (2025) and the future of robotics (2023) continues to shape the field. With over 120 citations across his most-cited works, Doenst’s research is pivotal for surgeons seeking to balance innovation with rigorous outcome data. His leadership in the MMIR and his critical perspective on surgical technique make him a key voice in the evolution of modern cardiac surgery.
