Ross-Konno procedure, Ross-Konno procedure
A diseased aortic valve will be replaced with the patient's own pulmonary valveand a prosthetic valve will replace the pulmonary valve, as in the Ross procedure.

The Ross-Konno procedure is an excellent technique for the treatment of complex multilevel left ventricular outflow tract obstruction with severe annular hypoplasia and a dysplastic aortic valve.

The operation can be performed earlier in life, thus avoiding repeated surgical reinterventions, which may provide only short-term palliation and potentially exacerbate ventricular function.

The Ross-Konno procedure increases therapeutic choices for neonates or infants with critical aortic stenosis, who show unacceptable results following open valvotomy or balloon valvotomy. The pulmonary autograft demonstrates durability without the likelihood of developing aortic stenosis or progressive dilatation and a low incidence of developing aortic insufficiency. Despite the technically demanding nature of the operation, the Ross-Konno procedure is the method of choice for the multilevel type of left ventricle outflow tract obstruction, especially in newborns and infants.

 It was not until the pulmonary autograft was combined with the Konno aortoventriculoplasty8 that it became such an attractive option for young patients with diffuse LVOT stenosis associated with significant aortic valve stenosis or dysplasia.

How to interpret the survival funnel plots

These graphs show the national average survival after specific procedures for treating congenital heart disease. The national average is shown as a horizontal grey line. Two control limits are shown; a warning limit (Green line, 98%) and an alert limit ( Red line 99.5%). Unit performances are shown as identifiable coloured symbols. If a unit's symbol is above the green line then the performance is no different from the national average. If a unit’s survival rate is below the warning limit, their performance will be closely monitored in subsequent years. If a unit’s survival rate is below the alert limit, an investigation into possible reasons and remedial actions will be launched by the appropriate professional and regulatory bodies.
