About

Leland Siwek is a pioneering cardiac surgeon whose work has redefined the landscape of minimally invasive heart surgery. His primary research focuses on robotic-assisted coronary artery bypass grafting (CABG) and integrated revascularization strategies. Siwek’s landmark contribution is the prospective multicenter trial of robotically assisted totally endoscopic coronary artery bypass (TECAB), a study with 224 citations that demonstrated the safety and efficacy of this advanced technique for single-vessel disease. He further advanced the field by championing integrated coronary revascularization, a hybrid approach combining robotic TECAB of the left anterior descending artery with percutaneous coronary intervention (PCI) for multivessel disease, offering patients a less invasive alternative to traditional open-heart surgery. His work on totally robotic mitral valve repair, including a multicenter study of 201 patients using a lateral “ports only” approach, showcased the feasibility of complex endoscopic repairs. With over 360 cumulative citations, Siwek’s research has been instrumental in establishing robotic cardiac surgery as a viable, patient-friendly option, reducing recovery times and surgical trauma. His contributions continue to inspire surgeons and researchers seeking to push the boundaries of minimally invasive cardiac care.
