BACKGROUND: Transcutaneous @entity338 (TPVR) has become an alternative to heart surgery for @entity1 after previous right ventricular outflow tract (RVOT) or pulmonary artery (PA) surgical interventions. The objective was to present immediate and long-term outcomes of transcutaneous @entity338 . METHODS: Between 06/2009 and 06/2016, 46 @entity1 underwent TPVR. Initial diagnoses included @entity215 , common arterial trunk, transposition of great arteries post Rastelli correction, left ventricle outflow obstruction after Ross operation, @entity1146 , and isolated @entity849 . Thirty eight @entity1 (78%) had previously implanted conduits in the pulmonary position, the rest had either RVOT patch reconstruction (n = 6; 13%) or biological valve implantation (n = 2; 4%). They presented primarily with @entity849 (n = 18; 39%) or regurgitation (n = 28; 60%). RESULTS: All procedures were successful - 44 Melody and 2 Edwards-Sapien valves were implanted. Before each procedure exclusion of potential coronary compression and RVOT prestenting was performed. Significant RVOT systolic gradient reduction (from 35.3    19.5 to 13.5    7.1 mm Hg; p < 0.001) and decrease of right to left ventricle systolic pressure ratio from 0.58    0.18 to mean 0.37    0.1 (p < 0.001) was achieved. Also, in every @entity1 PA-RVOT competence was restored, with minor @entity337 in only a few @entity1 . Post procedure follow-up ranged from 2 to 86 (mean 35.2) months. Follow-up fluoroscopy or chest X- @entity16039 revealed 6 stent @entity174 (2 stent defragmentation - with only one significant @entity849 ). CONCLUSIONS: TPVR is a safe procedure with encouraging results, it also enables deferring surgical reintervention in the majority of @entity1 .
