THE HEMODYNAMIC IMPACT OF MITRAL REGURGITATION, LEFT ATRIAL DYNAMICS, AND RIGHT VENTRICULAR TO PULMONARY CIRCULATION COUPLING DURING EXERCISE ON CARDIOPULMONARY EXERCISE PERFORMANCE AND CLINICAL OUTCOME IN LEFT HEART DISEASE

The hemodynamic impact of mitral regurgitation (MR), left atrial (LA) dynamics, and RV-to-PC coupling during exercise on cardiopulmonary function and clinical outcome has never been studied. 279 patients with exercise induced-dyspnea (120 HF, 56 aortic stenosis, 47 primary MR, 14 hypertrophic
