Aim: Generate a long term follow-up and evaluate the impact of clinical and procedural characteristics on long term events in percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation for unprotected left main coronary artery (ULMCA) disease.
Methods: Ninety-seven consecutive patients who underwent PCI with DES, either sirolimus (SES) or paclitaxel-eluting stent (PES), for de novo lesions in ULMCA were analyzed. No patients were excluded. Mean follow-up was 3 years (range 1-6.7 years).
Results: Technical and procedural success rate were 100% and 95.9%. According to the Academic Research Consortium definitions, cardiac death occurred in 6.1% of patients, reinfarction, target vessel revascularization (TVR) and target lesion revascularization (TLR) occurred in 6.1%, 17.5% and 4.2% of patients respectively. Definite stent thrombosis (ST) incidence was 1%, whereas possible ST occurred in 4.2% of patients. Postdilation was performed in 49.5% of patients and was, among all clinical and procedural characteristics, the only factor at multivariate analysis significantly related to lower MACE (25% vs. 46.9%, P=0.024, CI: 0.202 to 0.889) and TVR (8.3% vs. 26.5%, P=0.03 CI: 0.096-0.895).
Conclusion: Long term follow-up in PCI of ULMCA disease shows favorable clinical results. Stent postdilation seems to have a protective role in DES PCI for ULMCA disease.
