Cardiac Surgery Research

Clinical Research

Research is an integral part of our mission in the Weill Cornell Department of Cardiothoracic Surgery. We strive to understand the pathophysiologic mechanisms of cardiovascular disease, develop and improve treatment methodologies, and improve the quality of the care that we offer. We have an active clinical and translational research center that focuses on the major cardiovascular disorders including coronary artery disease, heart valve disorders, and aortic pathologies, such as aneurysms and other aortopathies.

Clinical Trials

Our department participates in numerous national trials sponsored by industry representatives. We participate in studies to evaluate a variety of novel cardiac implants, such as innovative heart valve implants, heart valve repair techniques, aortic grafts, ventricular assist devices, and end-organ preservation devices. Learn more

The ROMA Trial

Dr. Gaudino is also one of the Principal Investigators of The ROMA Trial, a two-arm event-driven randomized multi-center trial aimed at evaluating the impact of the use of one ITA vs two or more AGs for CABG on a composite of death from any cause, any stroke, and post-discharge myocardial infarction and/or repeat revascularization.


Dr. Mario Gaudino is the newly appointed director of the Joint Clinical Trials Office (JCTO) at Weill Cornell Medicine | NewYork-Presbyterian, Dr. Gaudino oversees ongoing clinical trials and lead strategic planning efforts.
