In the last case, the valve may grow and renew itself over time.

In this fastan we report our experience with the modified Konno-Rastan procedure, with inherent preservation of the native aortic valve and annulus, in the treatment of diffuse or unresectable SAS. One patient is awaiting reoperation for aortic incompetence unrelated to conal enlargement 1. However, the first two types of replacement valve will eventually need to be replaced as the function over time decreases.

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. Diffuse or unresectable subaortic stenosis SAS necessitates an aggressive surgical approach for the elimination of left ventricular outflow tract obstruction.

The modified Konno-Rastan procedure represents an excellent therapy for diffuse or unresectable SAS in patients with a rasttan aortic valve.

Valve and Conduit Replacements. Aortic Stenosis – Konno Procedure This procedure is performed in cases of Aortic Stenosis when the left ventricular outflow tract is stenotic in addition to the aortic valve itself. Eleven patients had undergone previous procedures rasgan 5 underwent the modified Konno-Rastan procedure as their primary operation.

When their function becomes impaired for any of these reasons, replacement becomes necessary. The aortic valve is replaced with either a mechanical valve Konno-Rastan Procedurean aortic homograft human aortic valveor with the patient’s own pulmonary valve. Most surgically implanted mechanical valves will last years before they wear out, become obstructed, or lose efficiency.

After the Konno Procedure, the possibility of renewed narrowing of the left ventricular outflow tract LVOT exists and the patient will need regular monitoring. The development of a new systolic murmur or the intensification of a soft murmur is an indication that the Kono should be investigated through echocardiography.

However, significant aortic insufficiency is uncommon in the adult patient and mild insufficiency is well-tolerated and raztan remains stable for long periods. In addition, it produces excellent results in a limited number of patients with hypertrophic obstructive cardiomyopathy, in whom the Morrow procedure traditionally has been performed.

If this becomes significant, reoperation will be necessary. This page is available in: There was 1 late postoperative death caused by pneumonia 2 years after operation 6.

The aortic valve itself also needs to be monitored to guard against progressive aortic insufficiency. Although it usually is performed through a raastan approach, the modified Konno-Rastan procedure also can be performed through a transatrial approach; this is particularly useful in patients who have had previous ventricular septal defect closure associated with SAS occurring proximal to the prosthetic patch.

One patient underwent a successful redo modified Konno-Rastan procedure 7 years after the first operation for residual left ventricular outflow tract obstruction immediately raastan the aortic valve.
