ObjectivesTo investigate the diversity and average values of bifurcation angles in a large population to help develop new methods.MethodsOne thousand five individuals (504 females, 501 male) who visited the Cardiology Polyclinic of Fırat University Hospital with the complaint of chest pain between 2010 and 2015 were evaluated retrospectively. Bifurcation angle measurements between LMCA-CX, CX-LAD, LMCA-LAD, CX-OM1, CX-OM2, LAD-D1, LAD-D2, RCA-RMD, RCA-RVD and PDA-PL were evaluated in all cases.ResultsBifurcation angles between LMCA-LAD, LMCA-Cx and LAD-Cx branches with "> 90 wide angle bifurcations", and Cx-OM1, Cx-OM2, LAD-D1, LAD-D2, RCA-RMD and PDA-PL with "<70 Y type bifurcation angle" were found to be high in male and female individuals. The RCA-RVD in female individuals was "<70 Y-type bifurcation" in 14 (2.8%) people, "> 70-90 T-type bifurcation" in 209 (41.5%) people, and "> 90 wide angle bifurcation" in 281 (55.8%) people. Results for male subjects were compatible with this. The correlations of all angles were examined. Robust positive correlations (p≤0.001) were found for the angular measurements between the main branches and the side branches (Cx-OM1, Cx-OM2, LAD-D1, LAD-D2 and RCA-RMD, PDA-PL).ConclusionWith the help of developing technology, we believe that all this coronary angiography data will guide bifurcation stent techniques, which are essential alternatives to bypass.Copyright: © Pakistan Journal of Medical Sciences.
