Overview

Cardiac catheterization is not frequently done to diagnose atrial septal defect, as it could be done confidently with echocardiography. It is in conditions when the echo findings are inconclusive. It can be used to determine the coronary anatomy.

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.
