ANGIOGRAPHIC PROFILE OF LEFT MAIN CORONARY ARTERY (LMCA) STENOSISстатья из журнала
Аннотация: Among patients with coronary artery disease, left coronary artery (LMCA) stenosis is the dangerous form of coronary arterial involvement, associated with increased mortality and morbidity unless immediate intervention is done.The gold standard treatment for left main coronary artery (LMCA) stenosis is the emergency coronary artery bypass grafting to its branches, left anterior descending artery (LAD), and left circumflex artery (LCX).Of percutaneous intervention in the form of angioplasty and stenting of left main coronary artery are increasingly done.The anatomy and the site of stenosis in the left main coronary artery determine the management option.In this context, the involvement of left main coronary artery and its anatomical pattern are important in deciding management options.AIM: To study the angiographic profile of significant Left main coronary artery (LMCA) stenosis among the patients who underwent coronary angiography.METHODS: A total of 1911 cases of significant coronary arterial disease, who underwent coronary angiography at King George Hospital, Visakhapatnam were studied in the present study and their coronary angiograms were analysed with respect to the pattern of involvement.RESULTS: of the 1911 cases of coronary artery disease, 118 patients have left main coronary artery disease.M/F ratio is 93/25.Of them 68.4% are hypertensive, 41.5 % are diabetics, 34.7% are smokers.Mean age of presentation was 59 yrs.Isolated LMCA involvement is seen in 5, associated with single vessel disease in 9, double vessel disease in 12 and triple vessel diseases in 93.Ostio-proximal involvement is seen in 21, mid segment involvement in 13, distal -bifurcation involvement in 93 and total occlusion of LMCA in 1 case.CONCLUSION: Significant LMCA involvement is seen in 6.1%.In majority of cases, it is associated with triple vessel disease and distal bifurcation is the commonest site involved.
