Through Tricuspid Closure for Doubly Committed Subarterial Ventricular Septal Defect with Right Vertical Subaxillary Mini-incision: A Matched-Pair Analysis

AbstractTo evaluate the feasibility and efficacy of the right subaxillary vertical mini-incision (RAVI) used for the closure of doubly committed subarterial ventricular septal defect (SAVSD) through tricuspid approach only. From June 2015 to September 2016, 32 SAVSD patients (mean age 2.4  ± 1.9 years, range 0.7–8 years) underwent surgical repair with either RAVI (incision length 3-4 cm) through tricuspid (group A, n = 16) or conventional median sternotomy incision through the main pulmonary artery approach (group B, n = 16). A retrospective 1:1 matched-pair analysi s was performed with the group B matched for defect size, body weight, gender, patching, and operation year. The demographic characteristics in both groups were similar. No patient died and only 1 patient in group B needed reoperation for sternal infection. The mean cardiopulmonary bypass (CPB) time and aortic cross-clamp time were 48.6 ± 12.6 min, 29.3 ± 8.5 min in the group A and 57.8 ± 14.1 min (p = 0.03), 34.3 ± 12.1 min (p = 0.18) in the group B. There was no significant difference between the two groups in the ICU stay (17.8 ± 8.9 h in group A, 18.7 ± 9.5 h in group B,p = 0.79), mechanical ventilation support time (2.7 ± 1.7 h in group A, 3.6 ± 1.5 h in group B,p = 0.11), postoperative hospital stay (6.3 ± 1.5 days in group A, 7.4 ± 1.7 days in group B,p = 0.06), and chest tube drainage (6.4 ± 4.3 ml/kg in...
