Describe demographic and clinical data of infant and pediatric with cardiac catheterization who admitted to cardiology unit of Assiut university children hospital Asses outcome of cardiac catheterization in pediatric and infant at AUCH

Cardiac catheterization and intervention in pediatric cardiac diseases have evolved significantly in the past 30 years. During the last 10 years, there have been major technological achievements in pediatric interventional cardiology There have also been substantial advancements in cardiac imaging modalities, such as intracardiac echocardiography (ICE), real-time 3-dimensional (3D) transesophageal echocardiography (TEE), cardiac computed tomography (CT) and magnetic resonance imaging (MRI), rotational angiography with 3D roadmap, holography, 3D printing, and Echo-Navigator and Vessel-Navigator systems. As a result of such technological advances, more types of congenital heart diseases (CHDs) can be treated in the cardiac catheter laboratory today than ever before. Therefore, the possibility exists that many surgical procedures will be replaced by catheter-based procedures

The pediatric interventional cardiology community has continued to develop less invasive solutions for congenital heart defects (CHDs) to minimize the need for open heart surgery and optimize overall outcomes. Many CHDs are effectively managed with transcatheter techniques. Atrial and ventricular septal defects, valve stenosis, patent ductus arteriosus, aortic coarctation, pulmonary artery and vein stenosis and arteriovenous malformations are some examples, routinely treated with catheterization in the pediatric population For most such interventions, these efforts lead to more highly acceptable outcomes and lower complication rates than the alternatives of surgery or no intervention
