Firas Zahr is a Senior Professor at Oregon Health & Science University specializing in cardiology and cardiothoracic surgery. His research focuses on valvular heart disease, transcatheter interventions, and structural heart devices, with particular emphasis on tricuspid regurgitation, mitral valve repair, and aortic regurgitation. He has led pivotal trials including the TRISCEND II study on tricuspid valve replacement and the ALIGN-AR trial of the Trilogy valve, publishing extensively in The Lancet, European Heart Journal, and JACC. His work also explores conduction disturbances, intracardiac echocardiography, and left atrial shunting in heart failure.
