Case Reports
Heart transplantation complicated by a patent foramen ovale of the recipient atrial septum.
A patent foramen ovale after heart transplantation is a relatively uncommon occurrence. We report a case of a 58-year-old man with profound hypoxemia after orthotopic cardiac transplantation for end-stage ischemic cardiomyopathy. Transesophageal echocardiography demonstrated the presence of a patent foramen ovale in the recipient atrial cuff. Primary closure was performed with correction of the right-to-left shunt.

Postoperative pulmonary hypertension is a life-threatening, yet reversible complication of congenital heart operations. Although inhaled nitric oxide (iNO), a selective pulmonary vasodilator, has been shown extensively to improve short-term oxygenation and hemodynamic indices in these patients, its influence on patient outcome has not been evaluated. The purpose of this study was to assess retrospectively whether patients who fulfilled our criteria for extracorporeal life support (ECLS) for critical postoperative pulmonary hypertension still required ECLS after the administration of iNO therapy. ⋯ Children with critical pulmonary hypertension unresponsive to maximal conventional treatment may be managed successfully with iNO without the need for rescue ECLS. A trial of iNO should therefore be given before the use of ECLS in these patients.
