Premature mitral valve opening: a new sign of severe mitral regurgitation
Abstract. A new echophonocardiographic sign of severe mitral regurgitation is described in a patient with left ventricular dysfunction and wide open mitral incompetence. Opening of the mitral valve before aortic valve closure may be seen with a low aortic diastolic pressure and an elevated left atrial V wave
