Safety and technical success of percutaneous left main coronary artery stenting
Objective: Critical stenosis of left main coronary artery (LMCA) has always remained a challenge for interventional cardiologists. Conventionally Coronary Artery Bypass Grafting (CABG) is done for these patients but recently Percutaneous Coronary Intervention (PCI) is also being tried more frequently, but data of PCI is scarce in this regard. Our objective was to determine the safety and technical success rate of percutaneous left main coronary artery stenting.
Methods: This was 12 month follow up study conducted at Pakistan Institute of Medical Sciences (PIMS), Islamabad from 11th Jan 2012 to 11th Jan 2013. All symptomatic patients who underwent coronary angiogram at PIMS and were found to have either isolated LMCA disease or coexisting osteal Left Anterior Descending (LAD) artery disease were potentially eligible for the study. Patients who had previous surgical treatment for coronary artery disease and those with renal dysfunction requiring dialysis were excluded. Patients were counselled in detail regarding the pros and cons of PCI versus CABG.Those who opted for PCI were included in the study. All these patients were treated with percutaneous left main coronary artery stenting with or without osteal LAD stenting.
Results: Seventy two patients had LMCA disease during angiogram. Fifteen patients opted for CABG. Four patients did not meet the inclusion criteria, whereas 53 patients were finally enrolled. Mean age of patients were 55.45±10.275 years. Twenty nine patients were with acute coronary syndrome and 22 presented with unstable angina.PCI with stenting was technically successful in all patients. One patient died three months after PCI, there was no other mortality.
Conclusion: Our study showed that Percutaneous Coronary Intervention (PCI) to LMS has good technical success rate; the safety of the procedure is also acceptable.
