The aim of this study is to find out and record the indications for diagnostic catheterization as well as for interventional cardiac catheterization in A.U.C.H , and record the outcome in these cases.

Cardiac catheterization is of two types:

diagnostic and interventional . There has been recent advances in these procedures.There is an over 10y experience at the pediatric cardiology unit in assiut University Children Hospital ( A.U.C.H ) catheterization department. The procedure usually follows other investigations used for evaluation of the pediatric cardiac patients e.g. chest X-ray , ECG and echocardiography.

The role of cardiac catheterization may be in the diagnosis of congenital cardiac anomalies as well as in the follow up of repair of some cardiac anomalies . On the other hand, the indications for interventional cardiac catheterization may be repair of Atrial septal defect, Transposition of great arteries palliation with balloon septostomy ,blood vessel dilatation e.g. aortic stenosis and coarctation of the aorta . In addition Patent ductus arteriosus closure and others may be done by the interventional cardiac catheterization.

Inclusion Criteria:

-all cases admitted for cardiac catheterization for diagnosis or intervention at Assiut University Children Hospital

Exclusion Criteria:

• cases not admitted for diagnostic or interventional cardiac catheterization

all cases admitted for cardiac catheterization for diagnosis or intervention at Assiut University Children Hospital
