- W180403586 abstract "Left main trifurcating coronary artery disease (LMTCAD) is a complex and challenging anatomy to treat percutaneously. We report on the immediate- and mid-term outcomes of 52 consecutive patients with LMTCAD treated with the Taxus(R) paclitaxel- eluting stent (PES) (Boston Scientific Corp., Natick, Mass.) in our center over a period of 2 years.All patients (n = 52) who underwent LMTCAD at our center in 2006-2007 and treated with the PES form the basis of this report. Demographic, clinical, procedural and in-hospital outcome variables were reviewed. Angiograms were analyzed by an operator blinded to the patients' history. Mid-term follow up was achieved from medical records and/or phone calls. The primary endpoint of the study was either cardiac death, nonfatal myocardial infarction or target lesion revascularization (TLR) on follow up. Follow up was achieved in 47/51 patients (92.2%) at a mean of 292.8 +/- 104.6 days. Patients were classified as Type A (30.8%) disease involving the LM and origin of branches, or Type B (69.2%) disease involving the origin of the trifurcation branches only, but not the LM artery. All patients were treated with kissing balloon after stenting. Descriptive analysis was performed on all variables with mean +/- standard deviation for continuous variables and percentages describing dichotomous variables. Univariate and logistic regression analyses were performed to determine the predictors of the primary endpoint.The mean patient age was 67.6 +/- 12.7 years. The LM artery was unprotected in 88.5% of cases. On follow up, the primary endpoint was met in 34% of patients. TLR occurred in 31.9% of patients, and target vessel revascularization (TVR) in 40.4%. One patient had cardiac death (2.1%) 5 months after the index procedure, possibly related to acute stent thrombosis. By univariate analysis, Type A lesions (vs. Type B; p = 0.02) and the placement of a greater number of stents (p = 0.044) correlated with a higher event rate. Logistic regression analysis showed that Type A lesions are the only predictors of the combined endpoint (p = 0.011).LM trifurcation stenting carries an overall high rate of adverse events, mostly driven by a high TLR rate. Type A lesions and the number of stents placed predicted a higher combined endpoint of death, nonfatal MI and TLR. By logistic regression analysis, Type A lesions are the only independent predictors of the primary outcome." @default.
