Objectives To assess the initial procedural and short to medium‐term experience with the straight design of the Venus P‐valve™ (Venus MedTech, Hangzhou, China) in dysfunctional right ventricular outflow tracts (RVOT). Background The Melody™ valve (Medtronic, Minneapolis, Minnesota) has been the only percutaneous valve option for smaller RVOT conduits. The straight Venus P‐valve™ may provide an alternative to the Melody™ valve. Methods Retrospective data collection of patient characteristics, procedural data, clinical and imaging follow‐up of the straight Venus P‐valve™. Results Nine patients (four female) with a mean age of 23.1 ± 7.5 years and a mean weight of 72.7 ± 29.4 kg underwent straight Venus P‐valve™ implantation between 03/2014 and 06/2016. All patients had right ventricle‐to‐pulmonary artery conduits which were pre‐stented before the valve implantation. All valves were deployed successfully without any significant procedural complications. During the mean follow‐up of 24 ± 9.1 months, there were no valve related re‐interventions or deterioration in valve performance. There was one case of insignificant, single wire frame fracture and no cases of endocarditis. The cohort demonstrated a reduction in pulmonary regurgitation and tricuspid regurgitation, which was sustained throughout the follow‐up. Similarly the gradient across the RVOT tract did not significantly increase. Conclusions Implantation of the straight Venus P‐valve™ has provided satisfactory short to mid‐term results with high success rates and no complications and may be considered as an alternative option in patients with RVOT dysfunction.
