Objective:
To demonstrate the efficacy of minimally invasive surgery via a vertical infra-axillary incision for complete tetralogy of Fallot (TOF) correction.
Methods:
In a study conducted from April to October 2023, 33 patients with TOF underwent total repair using this approach. On average, the patient age was 5.94 ± 2.68 months, weight was 6.49 ± 0.97 kg, and mean z-score index for the pulmonary valve annulus was -1.38 ± 0.92. Results also highlighted abnormal coronary artery pathways in 18.2% of cases, including 1 patient with dextrocardia and situs inversus.
Results:
The average incision length was 4.01 ± 0.6 cm, with bypass and clamping times of 95.42 ± 33.19 min and 69.24 ± 28.15 min, respectively. Preservation of the pulmonary valve annulus was achieved in 67% of patients. No postoperative deaths occurred, and there were no significant ventilation differences between groups. After surgery, no severe pulmonary valve regurgitation was observed, with patients remaining in excellent condition throughout the 7-month follow-up. The pulmonary valve pressure gradient after the procedure was 23.97 ± 10.65 mm Hg, and no heart failure cases were reported per the Ross classification at the latest follow-up.
Conclusions:
The vertical infra-axillary incision approach for total TOF repair is safe, effective, and cosmetically advantageous.
