Asian Cardiovasc Thorac Ann. Classic Konno-Rastan procedure: indications and results in the current era. 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.

Asian Cardiovasc Thorac Ann. Classic Konno-Rastan procedure: indications and results in the current era. 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 to November There were 26 patients 16 males and 10 females. The mean age at operation was The mean follow-up period was Only mechanical valves were used in this group of patients. The overall day mortality was The mean preoperative peak systolic gradient decreased significantly from 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.

Classic Konno-Rastan procedure: indications and results in the current era.

Meztirr It involves the replacement of the aortic valve and the widening of the ventricular septum in the region of the valve with a patch see illustration. However, significant aortic insufficiency is uncommon in the adult patient and mild insufficiency is well-tolerated and rastaan remains stable for long periods. One patient is awaiting reoperation for aortic incompetence unrelated to conal enlargement 1. There was a problem providing the content you requested Diffuse or unresectable subaortic stenosis SAS necessitates an aggressive surgical approach for the elimination of left ventricular outflow tract obstruction. The aortic valve itself also needs to be monitored to guard against progressive aortic insufficiency. Most surgically implanted mechanical valves will last years before they wear out, become obstructed, or lose efficiency.
