Abstract
Routine heart-catheterization after Coronary Artery Bypass Graft surgery (CABG) or Percutaneous Transluminal Coronary Angioplasty (PTCA) has been advocated to determine the change in bypass graft or dilated coronary artery and native coronary artery status, the effective disease remaining after CABG or PTCA and the relation between progression of disease, left ventricular function and symptomatology. Results of angiographic follow-up data after CABG and PTCA are presented and the practical implications are discussed. The reliability of symptoms, invasive and non-invasive test for the detection of ischemia are considered. Finally, recommendations are made for the indication of routine heart-catheterization after CABG and PTCA.
