Minimally Invasive ToF Repair in 2 Month Old Child
We are presenting the case of the minimally invasive total
repair of Tetralogy of Fallot in a 2 months old male patient.
Echocardiography showed good LV contractility, open permanent ductus arteriosus
(PDA), open permanent foramen ovale (PFO), large ventricular septal defect
(VSD), severe infundibular stenosis and hypoplastic main pulmonary artery (PA)
and PA branches
Our operation plan was: Right axillary minithoracotomy in 4th intercostal
space; Thymectomy; Central cardiopulmonary bypass (CPB) cannulation; PDA
closure; Aortic cross-clamp and cardioplegia administration; Trans-atrial VSD
closure with glutaraldehyde treated auto-pericardial patch; PFO closure;
Trans-annular right ventricular outflow tract (RVOT) and PA repair with
auto-pericardial patch closure.
For the right axillary access patient had been rotated on the left lateral
decubitus position. Horizontal skin incision was made over the 4th intercostal
space between anterior and posterior axillary lines. Large thymus was excised.
After pericardiotomy, cannulation for cardiopulmonary bypass was performed. Cannula
for IVC was inserted through the additional small incision in the 6th ICS. The
PDA was defined and closed. Aortic cross-clamp had been applied, antegrade cold
blood cardioplegia administered.
Closure of the VSD was performed through the TV using glutaraldehyde treated
auto-pericardial patch. No leaflets detachment was performed.
PFO was closed using polypropylene 5/0.
The main pulmonary artery incision was extended onto the right ventricular
outflow tract across the pulmonary valve annulus for 1cm. Left and right
pulmonary arteries were passed with a 6 mm Hegar. Muscle bundles of RVOT
obstruction were divided. Trans-annular auto-pericardial patch closure was
sutured with polypropylene 6/0.
Aorta was unclamped. Heart restored beating in sinus rhythm. Staged
decannulation was performed after achieving satisfactory hemodynamics. Wound
was closed in layers with nice cosmetic results.
The intraoperative echocardiography was done and no residual ventricular septal
defect and no residual RVOT obstruction was confirmed.
The duration of the operation time was 330 min, CPB time - 207 min. Aorta had
been cross-clamped for 115 min.
The patient’s postoperative course was unremarkable. He was staying in the
intensive care unit for 2 days. Patient was discharged from the hospital on the
7th postoperative day.
