Cardiac Catheterization

The following are a list of indications for undergoing a cardiac catheterization. The indications are generally categorized as either "diagnostic", or "therapeutic". The purpose of some catheterizations is to obtain clinical information that is not reliably or accurately obtained via other means ("diagnostic"). The purpose of some catheterizations is to repair some forms of congenital heart disease and obviate the need for surgical intervention ("therapeutic"). Therapeutic catheterizaions typically involve a diagnostic component where hemodynamic or anatomic information is obtained before performing the actual therapeutic procedure.  


Diagnostic Cardiac Catheterization

Hemodynamic assessment of congenital heart disease - provides anatomic detail in addition to calculation of the Qp:Qs ratio or pulmonary vascular resistance

evaluation of the degree of shunting across an atrial or ventricular septal defect


Anatomic assessment of congenital heart disease -

evaluation of arch anatomy

evaluation of coronary artery anatomy

evaluation of pulmonary venous anatomy


Therapeutic Cardiac Catheterization

1. Closure of an Atrial Septal Defect (ASD)

2. Closure of a Ventricular Septal Defect (VSD)

3. Closure of a Patent Ductus Arteriosus (PDA)

4. Balloon Valvuloplasty of a cardiac valve

5. Balloon Angioplasty of a blood vessel of the heart
