Surgical repair of pulmonary stenosis with intact ventricular septum in a 68-year-old woman.

Patients with mild pulmonary stenosis after infancy rarely have symptoms or develop increasing obstruction. We experienced a 68-year-old woman with severe pulmonary valvar and infundibular stenosis (peak to peak pressure gradient = 80 mmHg). She had been pointed out heart disease at the age of six. Endocarditis at the age of 17 might induce calcification of valve and affect the progression of pulmonary stenosis, and moreover, which might gradually develop severe subvalvar obstruction and poststenotic aneurysm of pulmonary trunk. She refused operative intervention because of mild clinical symptoms (NYHA class II), but we recommended surgical repair due to repeated transient ischemic attacks, which were suspected paradoxical embolism through persistent foramen ovale. She underwent pulmonary valvotomy and infundibular resection and is doing well.
