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.

Relatamos um caso de hipovolemia grave, acarretando obstrução dinâmica do trato de saída do ventrículo esquerdo, e grave regurgitação mitral. Após restaurada a normovolemia, essas anomalias foram completamente revertidas. Salientamos que diferentemente de outros casos, previamente relatados, o grau de regurgitação mitral em nosso paciente foi grave.
