Ventricular Septal Defects
Repair of ventricular septal defects (VSD) is performed with cardiopulmonary bypass and moderate hypothermia, aortic cross-clamping with cardioplegia, and profound local cardiac cooling. In small infants with associated complex anomalies, maximal exposure may be gained with cardiopulmonary bypass, deep hypothermia, and low-flow cerebral perfusion (about 0.25–0.5 L/min/m2) because total circulatory arrest is almost never used. The two cavae are selectively cannulated, and this allows work within the heart to progress during cooling and rewarming.
