Surgical palliation of primary pulmonary arterial hypertension by a unidirectional valved Potts anastomosis in an animal model.
Patients with idiopathic pulmonary hypertension are at risk for right-sided heart failure and sudden death. Despite improvement in pharmacologic management, some still require lung transplantation. Potts anastomosis has been demonstrated as a good palliation in children to alleviate symptoms and medical therapy despite desaturation in the lower part of the body. Young adult patients with pulmonary hypertension and isosystemic pressure remain at risk, particularly at exercise. The goal of this research was to find a palliation for patients in whom suprasystemic pulmonary hypertension developed at exercise. Creating a Potts anastomosis involved a unidirectional valve between the left pulmonary artery and the descending aorta. ⋯ Palliation of exercise suprasystemic pulmonary hypertension was demonstrated by a unidirectional valved Potts anastomosis. This technique can be of help in young adult patients with pulmonary hypertension and isosystemic pressure but with exercise intolerance.
