The mean fluoroscopy time was 29.8 minutes. None of the patients had significant outflow tract gradient or pulmonary regurgitation immediately after valve implantation. Only one patient had unexpected mild proximal valve migration to the right ventricular body during withdrawal of the delivery system. It caused mild paravalvar leak and significant tricuspid regurgitation. At 6 months follow-up, the median of right ventricular end-diastolic volume indices decreased from 146 to 108 ml\/m<jats:sup>2<\/jats:sup> (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 fracture on fluoroscopy or structural valve failure.<\/jats:p><\/jats:sec><jats:sec id=\"S1047951115001067_abs5\" sec-type=\"conclusion\"><jats:title>Conclusion<\/jats:title><jats:p>The Venus P-valve<jats:sup>TM<\/jats:sup> can be implanted successfully and effectively in patients with severe pulmonary regurgitation and a large right ventricular outflow tract.
