Material and Methods
Study design and patient population: This retrospective cohort research was studied in Bozok University Medicine Faculty Hospital Cardiovascular Surgery Department and approved by the Ethics Committee of Bozok University Medicine Faculty Hospital (Yozgat, Turkey)(2017-KAEK-189_2020.01.08_17). This study complies with the standards defined by the Declaration of Helsinki. Between January 2014 and May 2019, 196 patients had undergone CABG in Bozok University Medicine Faculty Hospital. Of the 196 patients, five were excluded from the study due to the total occlusion of proximal LAD. All the cases were reported by the single surgeon who had done the CABGs. The intramyocardial LAD (IMLAD) was identified by not being visualized on the surface of the heart in any part of its entire course. Each CAG images and reports of the patients contributing the study were analyzed prospectively by consulting with Cardiology Department.
The main limitation of our research is the inadequate numbers of cases in terms of statistical analysis. Therefore, the patient enrollment process continues and a yearly report of results and statistics is planned at the end of each 12 months.
