Diagnostic Value of Stress Right Heart Catheterization for Dynamic Mitral Regurgitation in Atrial Fibrillation.

ABSTRACT:

Background

Accurate evaluation of dynamic mitral regurgitation (MR) during stress echocardiography is challenging due to atrial fibrillation (AF), time constraints, and poor reproducibility.

Case presentation

An 85-year-old man with exertional dyspnea had moderate atrial functional MR on transthoracic echocardiography. Quantitative assessment during handgrip stress echocardiography was difficult due to AF. Stress right heart catheterization (RHC) with handgrip revealed increased mean pulmonary capillary wedge pressure and V-wave. The mitral transcatheter edge-to-edge repair markedly reduced MR. Postprocedural stress RHC demonstrated only slight increase in the mean pulmonary capillary wedge pressure and the V-wave. He remained free from heart failure hospitalization.
