Chronic thromboembolic pulmonary hypertension is associated with right ventricular dilatation, high right-sided filling pressures, and functional tricuspid regurgitation. The tricuspid regurgitation resulting from this disease has been postulated to be caused by tricuspid annular dilatation with displacement of the papillary muscles. Pulmonary endarterectomy is an operation that corrects the pulmonary ...
