SUCCESSFUL ENDOVASCULAR TREATMENT FOR LCA TRUNK TRIFURCATION LESION

Abstract

Left coronary artery (LCA) supplies blood to 75–100% of myocardial volume of the left ventricle (LV). The atherosclerotic lesion of LCA trunk causes an ischemia in the sufficient area of the myocardium that often results in LV dysfunction, heart failure, and arrhythmia. The risk of death in cases with this pathology reaches 50% at drug treatment. Several decades, coronary artery bypass graft surgery (CABG) was considered as "the golden standard" of treatment for LCA trunk stenosis. Due to the skills and experience in treatment for coronary pathology, new technologies development and stenting techniques, percutaneous transluminal coronary angioplasty (PTCA) for LCA trunk stenosis became more effective and safe treatment. Despite this, trifurcation of LCA trunk remains extremely difficult pathology for endovascular treatment, for a lack of sufficient experience. In the present paper we described successful endovascular treatment for trifurcation lesion of LCA trunk in a case with acute coronary syndrome (ACS).
