BACKGROUND: At present, the exclusion for percutaneous @entity338 for free @entity338 after tetralogy of Fallot repair includes an unfavourably large right ventricular outflow tract. OBJECTIVE: To report feasibility and early experience with a recently developed transcatheter heart valve, Venus P-valveTM, implanted in six @entity1 with severe @entity338 with large right ventricular outflow tracts. @entity1 There were two female @entity1 and four male @entity1 . The median age of the @entity1 was 18.5 years, and the mean body weight was 53.8 kg. All the @entity1 were in NYHA class II and had severe @entity338 after previous transannular patch repair of tetralogy of Fallot. The median time after the last surgical operation was 13.5 years. RESULTS: The Venus P-valveTM was successfully implanted in all the @entity1 with implanted valve diameters ranging from 24 to 32 mm. The mean fluoroscopy time was 29.8 minutes. None of the @entity1 had significant outflow tract gradient or @entity338 immediately after valve implantation. Only one @entity1 had unexpected mild proximal valve migration to the right ventricular body during withdrawal of the delivery system. It caused mild @entity2478 and significant @entity997 . At 6 months follow-up, the median of right ventricular end-diastolic volume indices decreased from 146 to 108 ml/m2 (p-value=0.046). The Doppler systolic peak gradient across the valve ranged from 4 to 40 mmHg, and there was no evidence of stent @entity174 on @entity712 . CONCLUSION: The Venus P-valveTM can be implanted successfully and effectively in @entity1 with severe @entity338 and a large right ventricular outflow tract. The early results with this valve are encouraging.
