Objective: The aim of this study is to define the correlation between intramyocardial left anterior descending artery (IMLAD) and coronary artery angiography (CAG); our clinical intraoperative experiences. Material and Methods: Between January 2014 and May 2019, 196 patients underwent coronary artery bypass grafting (CABG) surgery in Bozok University Medicine Faculty Hospital. The correlation between the typical “wide-U” image of left anterior descending artery (LAD) depression(Cicekcioglu sign) on CAG and our intraoperative surgical observations of the patients were studied. Results: Of the 196 patients, 5 were excluded due to the total occlusion of proximal LAD. 30 had a typical “wide-U” image(Cicekcioglu sign) on CAG and 22 were observed to have an IMLAD. Of the 25 patients being observed to have IMLAD intraoperatively, 3 had a normal preoperative CAG imaging. The prevalence of the IMLAD was 13%. Sensitivity of CAG was measured as 88% and specificity of CAG was 95.1%. Discussion: In CAG, in case of LAD composing a “wide-U” imaging(Cicekcioglu sign) the image of LAD course is often observed to have a correlation with the intraoperative detection of IMLAD.
