[Ventricular septal defect associated with pulmonary hypertension in monozygotic twins--a case report with surgical repair].

This is a report of two-year-old female monozygotic twins, both having a ventricular septal defect (VSD, Kirklin type II) and accompanying moderate pulmonary hypertension (PH). The two patients underwent a patch closure procedure to repair the VSD at the same time, and their postoperative courses were uneventful. Rubenstein and Weaver have reported the only case of surgical treatment for monozygotic twins having both VSD and PH. Our patients are the second such case of surgical treatment of VSD and PH in monozygotic twins.
