Abstract
Echocardiograms were recorded in nine patients with primary pulmonary hypertension proved at cardiac catheterization. A reduced diastolic slope of the anterior mitral valve leaflet, simulating mitral stenosis but with normal motion of the posterior leaflet, was observed in all patients. Other features found included a large right ventricular dimension (nine patients), a small left ventricular dimension (three patients), a thick interventricular septum (six patients), systolic mitral leaflet prolapse (four patients) and abnormal septal motion (four patients). The last feature was most probably due to secondary tricuspid or pulmonic insufficiency, or both. The finding of a decreased mitral valve slope, often used as a criterion for mitral stenosis, should not be accepted alone as proof of mitral stenosis; the posterior mitral valve leaflet echo must be carefully searched for and identified. This echo is often difficult to identify, but the normal motion of this structure found in all patients excludes the diagnosis of mitral stenosis as a cause for the pulmonary hypertension.This publication has 17 references indexed in Scilit:
