title: Severe volume depletion leading to mitral insufficiency.
abstract: We report a patient with profound hypovolemia who developed dynamic left ventricular outflow tract obstruction and severe mitral regurgitation. Both the outflow tract obstruction and mitral regurgitation resolved with volume replacement. Unlike previous reports of dynamic left ventricular outflow obstruction and mitral regurgitation, the degree of mitral regurgitation was severe. Possible mechanisms are discussed.
