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.
