Clinical images. Pulmonary edema without an obvious cause: handgrip-induced large dynamic changes in ischemic mitral regurgitation in the cath lab.

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's left ventricular systolic and end-diastolic pressures, his pulmonary and wedge capillary pressures, his heart rate and severe mitral regurgitation.
