Abstract
Introduction: Recognition of the length and variant branching pattern of LMCA is important because it may cause technical difficulties during coronary catheterization and stenting.
Methods: The Length and divisions of main trunk of left coronary artery (LMCA) were studied in patients who underwent coronary angiography for suspected coronary artery disease or for coronary intervention at a tertiary care centre in North India.
Results: The mean age of patients was 57.37 ± 10.60 years (Range 22-92 years). Long LMCA was observed in 16.41% cases and short main trunk in 9.06% cases. Division of main trunk into left anterior descending artery (LAD), left circumflex (LCx) and median artery was observed in 16% cases.
Discussion: Significant association is present between long LMCA and right dominance.
Keywords: coronary artery; coronary artery disease; coronary intervention.
