title: Cardiac catheterization in children.
abstract: Although cardiac catheterization in children is not without significant risk, it is mandatory before corrective cardiac surgery is undertaken. Not only can the procedure delineate the cardiac anatomy but it also yields information about the direction and amount of shunts, pulmonary vascular resistance and myocardial function. It is used to follow the severity of lesions such as aortic or pulmonic stenosis. Complications include cardiac perforation, renal impairment, neurologic problems and many others.
