        <p>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.</p>
