Transpulmonary arterial repair of type 1 ventricular septal defect will induce pulmonary regurgitation: Appraisal of subpulmonic approach

摘要: Objective A transpulmonary arterial approach to repair type I ventricular septal defect is the standard. However, possible adverse effect on pulmonary valve by this technique has not been investigated. Methods retrospective study reviewing from January 1991 May 2010 was conducted. Of 142 cases, repaired via route in 77 patients (54.2%, PA group) and subpulmonic 65 (45.8%, SP group). All received serial annual transthoracic color Doppler echocardiographic evaluation of function. Results The age at operation ranged 1.2 272 months (median, 35.0 months; mean, 50.4 months). mean follow-up period 96.2 (range, 2–234 Between groups, there no significant difference age, body weight, size, left right shunt amount, pressure, preoperative stenosis or regurgitation. Postoperatively, ejection fraction incidence residual defect, bundle branch block, stenosis. postoperative regurgitation more than moderate total scale were both significantly higher group (16.9% vs 4.6% 1.7 ± 0.1 1.4 0.1, P  = .031 .019, respectively). Conclusions Although for advocated decades, considering competency, may be an alternative.
