Utilization and Outcomes of the Nikaidoh, Rastelli, and REV Procedures: An Analysis of The Society of Thoracic Surgeons Congenital Heart Surgery Database.

ABSTRACT

BACKGROUND: Aortic root translocation (Nikaidoh), Rastelli, and réparation à l'etage ventriculaire (REV) are repair options for transposition of the great arteries (TGA) with ventricular septal defects and left ventricular outflow tract obstruction (VSD-LVOTO) or double outlet right ventricle TGA type (DORV-TGA). METHODS: This retrospective study using The Society of Thoracic Surgeons Congenital Heart Surgery Database evaluates surgical procedure utilization and outcomes of patients undergoing repair of TGA-VSD-LVOTO and DORV-TGA with a Nikaidoh, Rastelli, or REV procedure. RESULTS: A total of 293 patients underwent repair at 82 centers (January 2010 to June 2019). Most patients underwent a Rastelli (n = 165, 56.3%) or a Nikaidoh (n = 119, 40.6%) operation; only 3.1% (n = 9) underwent a REV. High-volume centers performed the majority of the repairs. Fewer Nikaidoh than Rastelli patients had prior cardiac operations (n = 57 [48.7%] vs n = 102 [63.0%]; P = .004). Nikaidohs had longer median cardiopulmonary bypass time (227 [interquartile range (IQR), 167-299] minutes vs 175 [IQR, 133-225] minutes; P < .001) and median aortic cross-clamp times (131 [IQR, 91-175] minutes vs 105 [IQR, 82-141] minutes; P = .0015). Operative mortality was 3.1% (95% confidence interval [CI], 1.0%-7.0%; n = 5) for Rastelli, 4.4% (95% CI, 1.4%-9.9%; n = 5) for Nikaidoh, and 11.1% (95% CI, 0.3%-48.3%, n = 1) for REV. The rates of cardiac arrest, unplanned reoperation, mechanical circulatory support, prolonged ventilation, and permanent pacemaker placement were higher in the Nikaidoh population but with 95% CIs overlapping those of the other procedures. CONCLUSIONS: Rastelli and Nikaidoh procedures are the prevalent repair strategies for patients with DORV-TGA and TGA-VSD-LVOTO. Most are performed at high-volume institutions, and early outcomes are similar.
