Abstract

Objective: This study evaluates the early results of mono-pulmonic cusp by contegra conduit minimally invasive surgery for tetralogy of Fallot


Summary: Tetralogy of Fallot is one of the most cyanotic congenital heart diseases, accounting for about 3,5% of all congenital heart diseases. One of the factors which affects the outcome surgery is the pulmonary valve (stenosis and regurgitation). Patient with severe stenotic pulmonary valve needs to transannular patch and there are alot monocusp techniques. To evaluative the early results of mono-pulmonic cusp by contegra conduit minimally invasive surgery for tetralogy of Fallot is study’s objective.


Method: Prospectie descriptive study, from 5/2024 to 11/2024, Fifteen consecutive Contegra monocusp transannular patch insertion perfomed during total repair of Tetralogy of Fallot via right axillary were included in this study. There were 10 males and 5 females; average age: 6,85 months; average weight: 6,5 kilograms. The z score of annulus pulmonary valve was minus 2,8.


Results: No patient had to stenotomy, average CPB  and  cross-clamping aortic  time  were  81  minutes  and  58 minutes. We used conduit contegra number 12 and 14. Hospital stay was 7,8 days. Echocardiography before discharge: no right ventricular outflow tract stenosis and 12 patients with no regurgitation and 3 patients with mild regurgitation. Follow- up postoperation 1 month: no death, all pulmonary valve were competence with 2 mild regurgitation and 13 no regurgitation.


Conclusions: The mono-pulmonic cusp by contegra conduit minimally invasive surgery for tetralogy of Fallot was feasible and brings good early results
