title: Echocardiographic findings in a patient with primary pulmonary hypertension.
abstract: This is a report of the echocardiographic findings in a 9-year-old white female with primary pulmonary arterial hypertension confirmed by catheterization and later at autopsy. The reported findings of an absent "a" wave, a flat diastolic E to F slope, and a midsystolic closure of the pulmonic valve were observed. In addition, tricuspid valve prolapse was noted. Prolapse of the tricuspid valve may be part of the mechanism of tricuspid insufficiency in a patient with pulmonary hypertension.
