Show full bio

Dr. Loor is passionate about maximizing donor organs for lung transplant recipients given the high mortality of patients on the waitlist and a shortage of donor organs. He has successfully initiated portable ex vivo lung perfusion (EVLP) research and clinical programs and is credited with the first “breathing lung” transplant in the Midwest and in Texas.

Dr. Loor received his cardiac surgical and transplant training at Cleveland Clinic, after which he spent several years at the University of Minnesota as assistant professor in cardiac surgery, surgical director of the lung transplant program, co-director of the aortic program and co-director of the adult congenital program. There he significantly increased the volume and quality of lung transplantation through donor utilization and launched the acute aortic emergency program.

Presently, as surgical director of the lung transplant program at Baylor College of Medicine, Dr. Loor’s goal is to lead the world’s largest and highest quality lung transplant program. He also offers and supports the highest standards of clinical excellence and quality in cardiac surgery. Dr. Loor specializes in both routine and complex adult cardiac surgery as well as surgery for advanced heart and lung failure. He also participates in the interventional program for mitral valve and aortic valve disease where minimally invasive techniques are used to avoid open surgery. Dr. Loor’s research interests focus on improving donor utilization and surgical outcomes through basic and translational science collaborations and participation in outcomes registries and clinical trials. Dr. Loor chairs the Cardiovascular Quality Initiative group at Baylor St. Luke’s which seeks to optimize patient outcomes through multidisciplinary collaboration.
