Outcomes of left main percutaneous coronary intervention

Objective: To study the outcomes of left main percutaneous coronary artery (LMCA) revascularisation. Study Design: A descriptive study. Place and Duration of Study: The Aga Khan University Hospital (AKUH), Karachi, from February till July 2016. Methodology: The study included all adult patients aged 18 years or more, who underwent percutaneous LMCA revascularisation at study centre from April 2006 till April 2015. In-hospital outcomes were ascertained of patients via charts along with telephonic follow-up for outcome ascertainment at 1-year and 5-year. Results were expressed in terms of means and standard deviation for quantitative variables and percentages for qualitative variables. Results: Of the 86 patients, the mean age was 66.05 ±12.6 years and 69% (59 cases, n=86) of them were males. Sixteen (18.6%) patients presented with cardiogenic shock and 17.4% (15 cases, n=86) required mechanical ventilation upon arrival. Among the 86 patients, 23.3% (20 patients, n=86) underwent PCI because of unstable condition for CABG and refusal by the surgeons. Mean follow up time for participants was 40.5 ±25.7 months with mean length of hospital stay of 4.36 ±2.4 days. In-hospital mortality was 12.8%, while mortality at 1-year and at mean follow-up was 7.3% and 6.9%, respectively. Conclusion: LM percutaneous coronary intervention is a viable option for patients who are hemodynamicaly unstable and require urgent revascularisation or for patients denying bypass surgery due to other reasons in Pakistan. Prospective studies in future may be required to evaluate the role of PCI for LM lesions in elective setting in contrast to existing treatment options.
