Key result
Right coronary artery dominance accounts for 83% of coronary patterns in Nepalese angiography patients.
Cross-Sectional (n=667)
No
In a Nepalese population undergoing coronary angiography, right coronary dominance is the most prevalent pattern (83%), consistent with global anatomical norms.

Local angiography data inform Nepal-specific procedural planning; leaves open generalizability of dominance patterns beyond this single-center cohort.
BackgroundThe dominance of coronary artery in our population is not known. This study aims to identify dominant coronary artery in Nepalese population.Material and MethodsThis study was carried out in the Cath Lab of Manmohan cardiovascular and thoracic centre Kathamandu over a period of 18 months (August2012 to April 2014). All patients of either gender who presented to the Cath lab for coronary angiography for different indications were included in the study. Patients with congenital heart diseases who were below the age of 18 years were excluded.ResultsA total of 667 patients were enrolled out of which 69% (n=488) were male and 31% (n=219) were female. The mean age was 51.3(30-76) years. Right coronary artery was dominant in 83%, left dominant in 10 % and co-dominant in 7% of the patient population.ConclusionThe right coronary dominant pattern is more prevalent in our population. Gender has no significant association with coronary dominance.

Nepal et al. (2016) conducted a cross-sectional in Patients undergoing coronary angiography (n=667). Coronary artery dominance pattern was evaluated on Prevalence of right coronary artery dominance. In a Nepalese population undergoing coronary angiography, right coronary artery dominance was the most prevalent pattern at 83%, followed by left dominance at 10% and co-dominance at 7%.
