We report a case of pulmonary edema experienced in a patient with severe left ventricular dysfunction without an obvious cause. Thus, we tested the hypothesis of a dynamic increase in the severity of (ischemic) mitral regurgitation. Right-and left-heart cardiac catheterization was performed before and after 2 minutes of maximal handgrip. We observed an increase in the patient\u2019s left ventricular systolic and end-diastolic pressures, his pulmonary and wedge capillary pressures, his heart rate and severe mitral regurgitation
