Abstract
A 7-month-old girl with false Taussig-Bing anomaly and partial atrioventricular septal defect (AVSD) was initially considered for the single-ventricle pathway. However, preoperative evaluation using a holographic workstation enabled precise ventricular volume assessment and intraventricular rerouting simulation. A virtual baffle confirmed the feasibility of biventricular repair. Volumetric analysis and cardiac magnetic resonance imaging predicted sufficient right ventricular volume post-baffle placement. The patient underwent successful biventricular repair via the Rastelli procedure and AVSD repair. Postoperative imaging verified adequate ventricular function. The holographic workstation proved cost-effective and may help determine biventricular repair viability in complex congenital heart diseases.
