Early and 1-year outcome and predictors of adverse outcome following monocusp pulmonary valve reconstruction for patients with tetralogy of Fallot: A prospective observational study.

摘要: Background and Objectives: Repair of tetralogy Fallot (TOF) with monocusp pulmonary valve reconstruction prevents regurgitation (PR) for a variable period. Since postoperative outcome is governed by PR right ventricular function, we sought to assess the severity outflow (RVOT) gradient in immediate period at 1 year attempted identify anatomical substrates responsible adverse outcomes. Methods: The study included 30 patients. Transthoracic echocardiography was performed before surgery, within 5 days later. Presence PR, RVOT gradient, residual branch stenosis were assessed. Right functions studied. Results: Median age 36.5 months (3-444 months). There no deaths. Pulmonary mild 18, moderate 10, severe 2 patients immediately following surgery. At year, 10 had one significant gradient. None variables like age, presence supravalvar stenosis, main artery diameter, or mobility found have any association progression PR. McGoon index Conclusions: TOF reduces underwent loss function proportion also progressed. This could not predictors though <1.5 tended more while those lesser
