[show abstract][hide abstract] ABSTRACT: Following percutaneous intervention (PCI), restenosis, progression of disease and multi-vessel involvement may require further intervention in the form of surgical revascularization. Patients with coronary artery bypass grafting (CABG) done after PCI were evaluated to find out the reason for the need of surgical revascularization. Over a period of 12 months, 610 patients underwent CABG. Out of them, 34 patients had previous PCI/stenting. Coronary risk factors including hypertension in 85%, diabetes mellitus in 60%, dyslipidemia in 60%, tobacco use in 50% and a positive family history was present in 53% of the patients. All patients were symptomatic. Multi-vessel disease was present in 67% and single vessel in 4.7%. The extent of disease and stenosis of stents were responsible for reintervention. Careful selection of patients is required in presence of multiple risk factors for coronary artery disease to provide maximum benefit by either PCI or CABG.

[show abstract][hide abstract] ABSTRACT: To evaluate outcomes of re-operative coronary artery surgery in a tertiary care hospital in a developing country.
Preoperative, intra-operative and postoperative variables were analyzed in 82 consecutive patients who underwent re-operative coronary surgery on cardiopulmonary bypass.
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.
Reoperative coronary artery bypass grafting is challenging but with expertise, team effort can be performed with good functional outcome.
