title: Classic Konno-Rastan procedure: indications and results in the current era.
abstract: Diffuse or unresectable subaortic stenosis is difficult to treat and needs aggressive resection to effectively relieve the obstruction. Anterior aortoventriculoplasty, known as the Konno-Rastan procedure, has been shown to effectively tackle the problems encountered in diffuse subaortic stenosis. A retrospective study was carried out on patients who had undergone a Konno-Rastan procedure at our institution from March 1997 to November 2003. There were 26 patients (16 males and 10 females). The mean age at operation was 12.8 +/- 7 years. The mean follow-up period was 30.4 +/- 14.5 months. Only mechanical valves were used in this group of patients. The overall 30-day mortality was 11.5% (3 patients). The mean preoperative peak systolic gradient decreased significantly from 91.3 +/- 39.3 to 28.1 +/- 17.7 mm Hg. Four patients developed permanent complete heart block and 2 had a residual ventricular septal defect in late follow-up. The classic Konno-Rastan procedure using a mechanical valve can be performed with acceptable morbidity and mortality in this difficult group of patients.
