Redo coronary artery surgery; early and intermediate outcomes from a tertiary care hospital in a developing country

Objective: to evaluate outcomes of re-operative coronary artery surgery in a tertiary care hospital in a developing country.method: preoperative, intra-operative and postoperative variables were analyzed in 82 consecutive patients who underwent re-operative coronary surgery on cardiopulmonary bypass.results: the mean age was 63.3 ± 7.7 years, 91.2% were male and 9.8% female. coronary artery disease risk factors were present in more than 50% of the patients. history of preoperative myocardial infarction was positive in 56% patients. there was strong clinical and angiographic indication for surgery with unstable angina in 50% patients and >80% had multivessel disease. only 5% patients were in functional class i. the risk stratification showed a mean euro score of 8. the iabp was used in 20% patients. a mean of 3.1 grafts per patient were applied. the median cardiopulmonary bypass (cpb) and aortic cross clamp time was 144 minutes respectively.postoperative mortality was 7.3%. short term follow up revealed 74% of the patients in nyha functional class i.conclusion: reoperative coronary artery bypass grafting is challenging but with expertise, team effort can be performed with good functional outcome.
