OBJECTIVES: Our objective was to determine the feasibility and early to medium-term outcome of stenting the @entity2461 at the time of radiofrequency valvotomy in the subgroup of @entity1 with @entity1146 with intact @entity67 and intermediate right ventricle. BACKGROUND: Stenting of the @entity2461 and radiofrequency valvotomy have been proposed as the initial intervention for @entity1 with intermediate right ventricle inasmuch as the sustainability for biventricular circulation or 1  -ventricle repair is unclear in the early period. METHODS: Between January 2001 and April 2009, of 143 @entity1 with @entity1146 and intact @entity67 , 37 who had bipartite right ventricle underwent radiofrequency valvotomy and stenting of the @entity2461 as the initial procedure. The mean tricuspid valve z-score was -3.8    2.2 and the mean tricuspid valve/mitral valve ratio was 0.62    0.16. RESULTS: Median age was 10 days (3-65 days) and median weight 3.1 kg (2.4-4.9 kg). There was no procedural mortality. Acute stent @entity715 developed in 1 @entity1 and necessitated emergency systemic-pulmonary shunt. There were 2 early in-hospital deaths owing to @entity998 . One late @entity204 occurred owing to @entity67 after the operation. Survival after the initial procedure was 94% at 6 months and 91% at 5 years. At a median follow-up of 4 years (6 months to 8 years), 17 (48%) attained biventricular circulation with or without other interventions and 9 (26%) achieved 1  -ventricle repair. The freedom from reintervention was 80%, 68%, 58%, and 40% at 1, 2, 3, and 4 years, respectively. CONCLUSIONS: Concomitant stenting of the @entity2461 at the time of radiofrequency valvotomy in @entity1 with @entity1146 with intact @entity67 and intermediate right ventricle is feasible and safe with encouraging medium-term outcome.
