Comparison of different pulmonary valve reconstruction techniques during transannular repair of tetralogy of fallot.

摘要: Background Transannular patch, which results in pulmonary insufficiency (PI), is usually required during repair of tetralogy fallot (TOF). In this study, we compared three types valve reconstruction techniques transannular TOF. Methods Between February 2014 and January 2018, 50 patients with TOF underwent primary patch. These were divided into groups. Group 1, (n = 15), a single gluteraldehyde-treated autologous pericardial patch (standard method) was reconstructed as monocusp. 2, 16) Nunn's bileaflet technique used 3, 19), performed expanded polytetrafluoroethylene membrane. The outcomes the early midterm competency valves analyzed. Results significantly effective postoperative period. Freedom from moderate to severe PI 73.3%; 100% 89.4%, respectively. Mortality, duration intensive care unit hospital stay similar between mean follow-up period 17.5 ± 13.0 (3-57) months. decreased 40%; 81.2% 73.7%, respectively at end Presence higher 1 (p .018 Groups p .048 3). Conclusion All provided competent valves. had better outcome midterm. It has potential delay right ventricular dysfunction long-term.
