INTRODUCTION: The ideal management strategy for @entity1 presenting late with @entity3886 ( @entity3886 ), intact ventricular septum (IVS), and regressed left ventricle (LV) is not clear. Primary switch, two-stage switch, and Senning operation are the options. Left ventricular retraining prior to arterial switch by ductal stenting may be effective, but the experience is very limited. METHODS: Five of six @entity1 aged 3-6 months with @entity3886 -IVS and regressed LV underwent recanalization and transcatheter stenting of ductus arteriosus. The ductal stent was removed during arterial switch surgery. RESULTS: The procedure was successful in 5/6 @entity1 . All the @entity1 had totally occluded ductus and needed recanalization with coronary total occlusion hardware. The ductus was dilated and stented with coronary stents. In all the @entity1 , there was significant luminal narrowing despite adequate stent placement and deployment. Two @entity1 needed reintervention for abrupt closure of the stent. Ductal stenting resulted in left ventricular preparedness within 7-14 days. One @entity1 died of progressive @entity295 after 14 days of stenting, even though the LV was prepared. Four @entity1 underwent successful uneventful arterial switch surgery. During surgery, it was observed that the mucosal folds of duct were protruding through the struts of the stent in one @entity1 . CONCLUSIONS: Ductal stenting is a good alternative strategy for left ventricular retraining in @entity3886 with regressed LV even in @entity1 with occluded ducts.
