Aim:
The aim of this study is to share our experience of the combined double-orifice and single-patch technique for the correction of partial atrioventricular septal defect (pAVSD) and its associated tricuspid valve dysplasia (TVD).
Methods:
Between January 2014 and May 2024, 99 patients (age ≥ 18 years) who underwent repair of pAVSD and its associated TVD using the aforementioned strategy were retrospectively analyzed.
Results:
The mean aortic cross-clamp time was 48.5 ± 12.6 min, and the mean cardiopulmonary bypass time was 75.8 ± 13.0 min. Follow-up was 100% at a mean of 5.2 years (3-8 years). No operative or late deaths occurred. No evidence of mitral stenosis was detected, and only one patient developed a severe MR 2 years after the surgery and underwent reoperation. There was no moderate or severe tricuspid regurgitation during follow-up. There was neither secondary tricuspid valve repair nor permanent pacemaker implantation among all patients.
Conclusions:
The combined double-orifice and single-patch technique is a safe, effective, and durable strategy for repair of pAVSD and its associated TVD, demonstrating an excellent technical reproducibility.
