Intermittent premature mitral valve closure in combined acute severe aortic and mitral regurgitation.
We have described the clinical, hemodynamic, and echocardiographic features of torn aortic cusps with mitral valve fenestration in a patient with infective endocarditis. Hemodynamic studies showed left atrial pressure intermittently exceeding left ventricular end-diastolic pressure. This phenomenon corresponded with intermittent premature mitral valve closure, which may serve as a marker for M-mode echocardiographic diagnosis in combined severe acute aortic and mitral regurgitation.
