ventricular septal defect closure
Surgical repair of abnormal communication between the left and right ventricles.
Full Definition
Ventricular septal defect closure involves surgical or transcatheter techniques to seal abnormal openings in the wall separating the left and right ventricles. Surgical closure typically employs patch repair using synthetic or biological materials, while transcatheter approaches use closure devices delivered via cardiac catheterization. The procedure eliminates left-to-right shunting, reduces volume overload on the left heart, and prevents development of pulmonary hypertension. Anesthetic management must consider the hemodynamic effects of the shunt and potential complications during closure.
Usage
Usage note: Often abbreviated as VSD closure. Distinguish from ASD (atrial septal defect) closure.
