Outcomes of percutaneous coronary intervention of coronary left main disease / Монголын Анагаах Ухаан

ABSTRACT

Introduction @#The left main (LM) bifurcational stenting is coronary high risk interventional procedure (CHIP) which associated with various post procedural outcome.@*Goal@#In this study, we aimed to describe current practice of coronary left main bifurcational stenting and patient’s outcome in Mongolia. @*Materials and Methods@#We selected 50 patients who gave informed consent and treated by left main bifurcational stent. All the patients gave informed consent form which was approved by ethical committee of Mongolian National University of Medical Sciences. Coronary stenosis was evaluated by Syntax score and Medina classification. The 1 year survival rate was estimated using Kaplan-Meier estimation. @*Results @#A total of 50 patients who received LM bifurcational stent were chosen (mean age 60±11, male gender 78%). Mean syntax I score was 26.1±8.6 and mean Syntax II score was 44.7±6.2. Medina 110 type lesion was 46% (n=23), medina 111 type lesion was 36% (n=18), medina 100 type lesion was 6% (n=3), medina 011 type lesion was 4% (n=2) and medina 010 type lesion was 8% (n=4). The median degree of stenosis was 50% (IQR 30%; 90%) for LM, 90% (IQR 80%; 99%) for LAD and 0% (IQR 0%; 80%) for LCx. The final procedural success with final TIMI 3 flow was achieved in 44 patients (88%). All-cause mortality was occurred 5 patients during follow-up and survival rate at the 1 year was 82% (95% CI 66; 97).@*Conclusion @#The bifurcational stenting is acceptable treatment choice which has good survival for high risk patients with LM bifurcational disease.
