Background: Patients who underwent percutaneous coronary intervention in left main coronary artery (LMCA) requires special concern, being high risk and increasing patient population. The aim of this study was to assess the clinical profile, angiographic status, and prevalence of restenosis in patients who underwent percutaneous transluminal coronary angioplasty (PTCA) in LMCA. Materials and Methods: This observational cohort study included 17 patients who underwent PTCA in LMCA during one-year study period at tertiary care centers in Government Medical College, Kozhikode, India. Data including various risk factors, clinical and angiographic details, stent used, procedural complications and outcomes including rate of restenosis were analyzed. Results: A total of 17 patients (mean age 53.88 ± 9.80 years) with 76.47% of males were included in the study. Smoking and hypertension were the most common risk factors presented in 52.94% and 47.06% of patients respectively. Single vessel disease (SVD) of LMCA was the most common pattern observed in 47.10%; the rate of restenosis was observed in 11.76% patients. Revascularization was performed in one patient (5.88%) with coronary artery bypass graft and in one patient (5.88%) with PTCA using drug eluting stent (DES). The overall procedural success was 88.24% in this study. Survival rate was 100% at one-year follow-up period. Conclusion: Our study involved patients who underwent PTCA in LMCA, showed smoking as a most prevalent risk factor for coronary artery disease and SVD as a most common pattern, comparatively low rate of restenosis and 100% of survival rate at one-year follow-up period.
