Exercise-Induced Left Bundle Branch Block Resulting in Severe Mitral Regurgitation

Exercise hemodynamic catheterization is helpful to evaluate exertional symptoms when noninvasive investigations fail to provide an explanation in non-ischemic cardiomyopathy. In this case, a rate-related left bundle branch block resulted in severe dynamic mitral regurgitation and acute increase in p...

description Exercise hemodynamic catheterization is helpful to evaluate exertional symptoms when noninvasive investigations fail to provide an explanation in non-ischemic cardiomyopathy. In this case, a rate-related left bundle branch block resulted in severe dynamic mitral regurgitation and acute increase in pulmonary capillary wedge pressure. Cardiac resynchronization therapy resolved her symptoms. (Level of Difficulty: Intermediate.)
