Percutaneous Coronary Intervention for Isolated Left Main Coronary Artery Disease: A Single Centre Experience.

Objective: Isolated left main coronary artery disease (ILMCAD) is not a frequent one. Though coronary artery bypass graft surgery (CABG) was thinks to be the standard treatment for left main coronary stenosis (LMCA). However, in the real world scenario, multiple studies suggests that treatment of patients with isolated left main coronary artery disease (ILMCAD) with percutaneous coronary intervention (PCI) can be a safe & suitable option. Methods: This prospective observational study was carried out for 1 year between '01st February 2021 to 31st January 2022'. A total of 10 patients presented with Angina or NSTEMI & whom CAG reveals isolated left main coronary artery diseases were enrolled for this study. PCI to Left Main Coronary Artery was done with newer generation DES for all of this patients & six months outcome was recorded. Results: Mean age of the patients was 44.1±6.6 years. Among them male was 7 (70%), female was 3 (30%). Hypertension (70%) was the most common risk factor followed by smoking (60%), dyslipidemia (60%), diabetes mellitus (50%) and positive family history for IHD (50%). Among the total of 10 patients, 07 (70%) patients had chronic stable angina & 03 (30%) patients had NSTEMI. Ostial left main was involved in 03 (30%) patients, shaft involvement in 03 (30%) patients, 02 (20%) distal left main disease (Medina classification-1,0,0) & whole segment disease in 02 (20%) patients. Mean SYNTAX score was 11.1 ± 1.1 with majority of patients having low SYNTAX score. All patients were treated with newer generation DES implantation. The post procedural outcome was satisfactory in all patients. No patient developed any Major Adverse Cardiovascular Events (MACE) during the study period. Conclusions: Left main PCI with newer generation DES can a suitable option with favorable outcome to treat the patients who have isolated left main coronary artery disease. [ABSTRACT FROM AUTHOR]
