We describe the case histories of 2 patients less than 6 months of age in whom ventricular septal hematomas developed in the early postoperative period. Both cases were managed expectantly with complete resolution and no long-term sequelae.
Clinical Summaries
Patient 1. The first patient was seen at 2 days of age with poor feeding and a cardiac murmur. An echocardiogram confirmed the diagnosis of type B interrupted aortic arch, posterior malalignment ventricular septal defect (VSD), and ascending aortic hypoplasia. After stabilization, she underwent complete 1-stage surgical repair. With the use of deep hypothermic circulatory arrest, the aortic arch was reconstructed and augmented with pulmonary homograft material. The malaligned VSD was approached through the tricuspid valve. A series of pledget-supported interrupted sutures were placed through the defect margins and a patch of Dacron material secured into position. The patient was weaned from bypass on low-dose dopamine with no rhythm or hemodynamic concerns. Total cardiopulmonary bypass time was 103 minutes. Aortic crossclamp time was 89 minutes. The circulatory arrest time was 43 minutes. A prominent ventricular septal mass with cystic characteristics was noted on postoperative day 1
