- Abstract
We report here the worsening of functional mitral regurgitation (MR) during dynamic exercise Doppler echocardiography in four female patients with heart failure and preserved ejection fraction. MR worsened concomitantly to an increase in systolic mitral tenting area and in E/Ea ratio, whereas local left ventricular (LV) remodelling was not substantially aggravated by exercise. We accordingly suggest that exercise-induced increase in LV filling or left atrial pressure that in turn leads to increase in mitral tenting area worsens functional MR during exercise.
