Echocardiographic findings of mitral and tricuspid valve prolapse in primary pulmonary hypertension.
Echocardiographic findings in six patients with primary pulmonary hypertension are presented. Four of six patients had abnormal septal motion with prolapse of mitral and tricuspid valves. The other two had none of the three echocardiographic abnormalities. It is possible that hemodynamic changes in ventricular pressure gradients across the interventricular septum cause an abnormal septal motion and secondary AV valve prolapse.
