Ootaki Y. Simultaneous repair of pectus excavatum and congenital heart disease over the past 30 years. Eur J Cardiothorac Surg

Objective: Pectus excavatum may be present in patient requiring operations for cardiac defects. The study was undertaken in order to assess our simultaneous repairs of pectus excavatum and congenital heart disease over past 30 years. Methods: Between 1970 and 2000, 12 patients underwent simultaneous repair of pectus excavatum and congenital heart disease. Six of 12 patients had ventricular septal defects as cardiac malformations (subgroup A). Operative technique, after the intracardiac procedure using cardiopulmonary bypass, consists of total subperichondrial resection of deformed costal cartilages, transection of deformed portion of the sternum in 2–3 points, and fixation of the sternum in elevated position using two Kirschner wires and a bridge external traction. Postoperative catheterization was performed in five of 12 patients (subgroup B). We evaluated the operative data, the improvement of pectus deformity and right ventricular performance retro-spectively. The operative data in subgroup A were compared with those in recent random patients with ventricular septal defects only or with pectus excavatum only (control groups). Results: There was no operative death and non-serious complications were seen in nine patients (atelectasis in six, superficial wound infection in two, chylothorax in one). Pectus deformities improved with the drop of vertebral index postoperatively. The mean total operative time and postoperative drainage in subgroup A were 128.4 % and 123.7%, respectively of those in the ventricular septal defect control group. The mean perioperative bleeding in subgroup A was more than the sum of those in control groups. Right ventricular end-diastolic (RVEDVI), end-systolic (RVESVI), stroke (RVSVI) volume indices and ejection fraction (RVEF) in subgroup B tended to increase after surgery. In particular, there were significant increases of RVEDVI (35%, P, 0:05) and RVSV
