Coronary dominance and predictors of adverse events during coronary interventional procedures: an observational study

Abstract

Background: Coronary dominance is associated with adverse peri-procedural events during coronary interventions. There are limited data regarding events during coronary angiography in Nepal.

A study of coronary dominance and its clinical significance

“…Another study found that left dominance was seen in 9.8 % cases and non-left dominance in 90.2 % samples. Few studies even found an opposite dominant pattern with a high prevalence for left dominance or for co-dominance patterns and lower prevalence percentages for right dominance [19,[22][23][24][25]. There is a need to delve further into this aspect of coronary dominance as these variations should not merely be a consequence of different assessment methods used.…”

“…When the branches from both the distal RCA and the distal LCx artery cross the inferior interventricular septum, it was termed as co-dominance. This was reported to have a prevalence of 7-8 % [3].Different studied by various authors confirm that the coronary artery system was right dominant in 85%, left dominant in 8% and co-dominant in 7% of cases [4][5][6][7]. Certain recent studies indicated a high prevalence for left dominance followed by co-DP and lower prevalence percentages for right dominance pattern (DP).…”
