Cardiac cathetreization

• Diagnostic cardiac catheterization is usually not done in uncomplicated ASDs as non-invasive methods like echocardiography can diagnose atrial septal defects with greater confidence.

• However, they are used in certain conditions like-
  • Coronary artery disease assessment in patients who are at risk due to age or family history
  • Catheterization now days are done along with device closure in patients who are planned for surgical intervention
  • It can be used to assess pulmonary vascular resistance in cases with pulmonary artery hypertension
  • It can also be used to evaluate atrial septal defect size, pulmonary venous return, and associated valvular disease in case the other noninvasive methods are inconclusive.
