OBJECTIVE: To assess the efficacy, safety and advantage of direct coronary stenting versus traditional angioplasty and stenting. METHODS: From May 2000 to June 2001, 486 patients underwent PTCA procedure. One hundred fifteen (24%) were considered candidates for direct stenting. Out of 150 coronary lesions, 119 (79%) had direct coronary stenting. In 5% patients stent could not be passed across the lesion. These stents were withdrawn without stent damage and after predilatation the same were successfully deployed. RESULTS: Primary success rate was 95%. Angiographically assessed success was achieved in all patients with immediate TIMI 111 flow in 97%. The vessels directly stented were LAD 53%, RCA 27% and LCX 18%. Two saphenous vein grafts were also directly stented. The coronary lesions stented were type A 36%, B1 54% and B2 10%. In borderline lesions IVUS was used for quantification of stenosis. There was no in-hospital death, MI or emergency CABG. Compared to traditional stenting there was 46% reduction in procedure time, 62% reduction in radiation exposure time and 35% decrease in use of contrast media. There was also significant (18%) cost benefit in direct stenting. CONCLUSION: This study supports the view that direct coronary stenting is feasible and a safe procedure in our population with additional benefits of cost reduction by 18%. We recommend direct stenting in appropriately selected patients.
