[Efficacy of stenting for selective unprotected left main coronary artery disease: two-year follow-up of 416 patients].
OBJECTIVE
To evaluate the safety and effectiveness of stenting for selective unprotected left main coronary artery (ULMCA) disease.


METHODS
The clinical data of 416 patients with ULMCA who underwent selective percutaneous coronary intervention (PCI) were analyzed.


RESULTS
In 291 of the 416 patients (70.0%), the ULMCA lesions were located in the distal bifurcation site. A total of 503 stents were successfully deployed in 414 patients and the mean stent number was (1.2+/-0.7) stents per patient. The success rate of stenting procedure was 99.5%. During hospital stay, no patient died. The major adverse cardiac event (MACE) during in-hospitalization was 0.5% (2/416). The target lesion revascularization (TLR) rate was 4.9%. During the follow-up 16 (3.9%) patients died including 12 cases (2.9%) of cardiac death. Angiography during follow-up conducted on 136 (33.1%) patients showed that binary in-stent restenosis occurred in 20 patients (14.7%, 20/136). TLR was performed by coronary artery bypass graft in 14 patients and by drug eluting stent (DES) implantation in 6 patients respectively. The total MACE rate was 8.3% (34/411).


CONCLUSIONS
Safe and with favorable clinical outcome, selective coronary stenting for ULMCA lesions can achieve a high technical success rate.
