Stenting versus non-stenting after revascularization of chronic total coronary artery occlusion: short- and long-term clinical and angiographic results.
OBJECTIVE
To investigate the short- and long-term clinician and angiographic outcome of stenting or angioplasty for chronic total coronary artery occlusion.


METHODS
A total of 95 patients with successful percutaneous transluminal coronary angioplasty (PTCA) for total occlusion coronary artery were identified out of 358 patients undergoing PTCA for chronic total occlusion. Patients were classified into two groups: Group A had selective stenting after successful PTCA and Group B only had PTCA. Clinical cardiac events including acute myocardial infarction (AMI) angina, death, repeat revascularization and angiographic variables were followed and analyzed.


RESULTS
A total of 85 of 95 patients (89%) completed clinical and angiographic follow-up. In group A (n = 42), 1 patient experienced an AMI while in group B, 2 patients experienced AMI and 1 died. In group A, the restenosis rate was 29%, reocclusion rate was 12% and recanularization rate was 19%, as compared to 58%, 22% and 45% respectively in group B (P < 0.001, P < 0.05 and P < 0.001, respectively).


CONCLUSIONS
Selective stent improves short- and long-term clinical and angiographic outcomes and is recommended in cases of chronic total occlusion independent of the primary PTCA results.
