Importance of bifurcation and proximal angle in generation of coronary lesion




Background


Linear blood flow through normal coronary artery becomes turbulent flow at branching points exerting shear force on the bifurcation site which in turn predisposes for development of obstructive coronary lesions. We hypothesize that bifurcation angle (BA – angle between the distal main vessel and side branch) and proximal angle (PA- angle between the proximal main vessel and side branch) of branching site are also important in generating more vertices of blood flow. For that we did quantitative coronary angiogram analysis (QCA) with BA, PA measurement of diseased and non-diseased coronary bifurcations in different coronary territories.




Methods


We did analysis of 65 normal and 36 significantly diseased LAD – D1, 72 normal and 27 significantly diseased LCX – OM , 73 normal and 16 significantly diseased RCA – PDA – PLV and 34 normal and 14 significantly diseased LMCA – LAD – LCX bifurcations. For QCA of bifurcation lesion we used a routine conventional QCA software.
