Abstract
A total of 35 patients completed the study. Mean age was 19.8 (±4.2) years, with a male-to-female ratio of 4:3. A total of 25 patients had uncorrected TOF, and 10 had undergone intracardiac repair. After the procedure, patients with uncorrected TOF showed a significant increase in oxygen saturation from 84.7% (±1.4%) to 94.6% (±1.2%). Procedural success was 91.4%, with 3 patients experiencing significant restenosis. No procedural complications were observed. There were no arrhythmic events until the first year of follow-up. At 1-year follow-up, the mean RVOT pressure gradient was significantly decreased, and all patients remained symptom-free. In conclusion, combined balloon pulmonic valvuloplasty and conal artery occlusion is a safe and effective method for alleviating RVOT obstruction in patients with TOF, showing promising intermediate-term outcomes with minimal complications.
