[Stenting of unprotected left main coronary artery: complications during 3 years follow up].
Aim of investigation was to study complications during 3 years follow up of patients after implantation of standard metal stents (SMS) in unprotected left main coronary artery (LMCA). Patients with high risk of surgery (n=124) with stenting of unprotected LMCA performed between August 2002 and November 2004 were included in this investigation. Study end points were death, myocardial infarction, repeat vessel revascularization. Success of intervention was achieved in 96.7% of cases. Mean duration of follow up was 38.1 +/- 1.8 months. Death due to cardiac causes was registered in 6.5% of cases, 3 of these deaths were sudden. Noncardiac mortality was 3.2% (4 patients died). Peripheral complications were noted in 1 case: in one patient pseudoaneurism of femoral artery developed and was successfully resolved by compression under ultrasound control. Restenosis in stented segment during follow up was noted in 25 patients (20.2%). Repeat percutaneous coronary intervention (PCI) was carried out in 18 patients. In other cases patients were referred to coronary bypass surgery. Total survival of patients in the investigation was 95.2, 91.9, 90.3% in 1, 2, an 3 years, respectively. Despite high success of PCI of unprotected LMCA with the use of SMS and relatively low percent of restenosis it is necessary to use this method carefully in the treatment of patients with lesions in unprotected LMCA. We consider PCI in unprotected LMCA justified only in patients with high risk of surgical intervention who are not suitable candidates for coronary bypass surgery.
