“…Surgical relief of severe obstruction by valvotomy with a transventricular 838 or transpulmonary artery 839 approach predates the introduction of cardiopulmonary bypass. A nonsurgical approach with balloon valvotomy was described in 1982 840 and by the late 1980s had become the procedure of choice in the United States for the typically domed, thickened valve, both for children 841 and adults.…”

“…The excellent overall survival confirms previous reports of the efficacy of cardiac surgery for isolated pulmonary stenosis. [1][2][3][4][5][6] This study also provides new data documenting a normal life expectancy over a 20-30-year period for hospital survivors who underwent repair at age 21 years or younger. These data, which come from the earliest experience in cardiac surgery, should provide a standard for comparison with the era of contemporary surgical practice and the newer techniques of percutaneous balloon valvuloplasty.…”

Patients and Methods PatientsAll patients who underwent surgical repair of isolated pulmonary valve stenosis at the Mayo Clinic between 1956 and 1967 are included in this study. These dates were selected to allow a minimum follow-up of 20 years (or until death); the maximum follow-up is 30 years. The diagnosis of isolated pulmonary stenosis included patients in whom the only other congenital cardiac abnormality was an atrial septal defect but with less than 20% left-to-right shunt (quantitated by oxygen saturations by the Van Slyke method). Patients with pulmonary valve atresia or the hypoplastic right heart syndrome were excluded from this study. These criteria were met by 191 patients, of whom 99 (52%) were male. The mean (±+ SD) age at operation was 13.6±+13.1 years (range, 3 days to 68 years; median, 9 years) ( Figure IA). Associated conditions included atrial septal defect in 42 patients, patent foramen ovale in 30 patients, and anomalous origin of the left anterior descending coronary artery from the right coronary artery in one patient. No other congenital cardiac abnormalities were present.The follow-up status of the patients was determined by examination at this institution or by a detailed questionnaire. If interim death, hospitalization, or a cardiovascular event had occurred, either

Of 264 patients undergoing pulmonary valvotomy for pulmonary stenosis or atresia at the University of Minnesota, 23 had a right-to-left shunt preoperatively. In none was the atrial communication closed at the time of pulmonary valvotomy. At postoperative cardiac catheterization, no atrial level shunt was found in 19, indicating that effective closure of the communication had occurred. In the remaining 4, a right-to-left shunt persisted despite adequate relief of the stenosis. Each of the 4 has undergone subsequent closure of the atrial septal communication without difficulty.
