Association of Body Mass Index With Outcomes in Patients Undergoing Transcatheter Mitral Valve Repair

Obesity is a major independent risk factor for premature death due to cardiovascular diseases. Several studies have reported a better prognosis for obese patients who underwent transcatheter aortic valve replacement, coronary artery bypass grafting, hypertension, and heart failure compared with their leaner counterparts.1,2 This counterintuitive phenomenon has been described as an “obesity paradox,” and the exact pathophysiological mechanism of this association is not fully understood. Mitral regurgitation (MR) is the most frequent form of valvular heart disease in the United States.
