title: Attenuated early diastolic interventricular septum bulging by pulmonary hypertension due to later developed aortic regurgitation.
abstract: A woman was admitted due to dyspnea. She had familial pulmonary arterial hypertension and typical echocardiographic findings including early diastolic bulging of the interventricular septum toward the left ventricular cavity. Her symptoms improved with medication. Five months later, she was hospitalized again due to severe dyspnea. Echocardiography demonstrated aortic valve vegetation and its regurgitation. Echocardiography also showed attenuation of early diastolic compression of the interventricular septum, however, the peak tricuspid regurgitant flow velocity did not improve. It is likely that development of left-sided heart failure attenuated abnormal interventricular septal motion due to pulmonary hypertension.
