THERAPEUTIC CARDIAC CATHETERIZATION PROCEDURES

Echocardiography has now replaced cardiac
catheterization as a diagnostic procedure in children
born with congenital cardiac defects. Advances in technology have encouraged developments in balloon dilatation of obstructive cardiac lesions, creation of atrial
defects, c10sure of defects and abnormal blood vessels
and removal of intravascularforeign bodies. Percutaneous techniques have encouraged pacemaker implantations and radio frequency ablation of abnormal intracardiac electrical pathways to terminate malignant cardiac
rhythms. Cardiac catheterization therefore is no longer
just a diagnostic procedure but a therapeutic procedure
aswell.
