Background: The rheumatic cardiac valve diseases are one of the most important heart problems in Turkey. In mitral valve surgery, the relationship between the anulus fibrosus sinister and the coronary arteries is extremely critical for the postoperative life of the patient.
Methods: The study was performed with human adult hearts. The aim of this study of 50 hearts was to understand the existing correlations between the mitral annulus and the coronary arteries. We determined the right or left dominance or codominance of the anulus fibrosus sinister on each heart and stu died the relationship of the mitral annulus to the circumflex coronary artery (CCA) and the left posterior descending coronary artery.
Results: The distances of the anulus fibrosus sinister from the CCA and interventricularis posterior arteries w e re measured with a flexible ruler. In 19 of 50 cases, the distance of the coronary artery from the annulus was 3 mm at 23 different points, 2 mm at 8 different points, and 1 mm at 2 different points.
Conclusions: In mitral valve surgery, damage to the CCA can occur, especially in patients with left coronary dominance or codominance in which the CCA is running in the atrioventricular groove very close to the mitral annulus. Therefore, this study emphasizes the importance of knowing the coronary artery anatomy preoperatively.

Background: The fluorescent dye indocyanine green (ICG) has been used to identify anatomical structures intraoperatively in coronary artery bypass grafting (CABG). This study aimed to evaluate the feasibility of using ICG to assess graft patency and territorial distribution of myocardial reperfusion during CABG.
Methods: Porcine arrested hearts (n = 18) were used to evaluate territorial distribution of native coronary arteries and of a coronary bypass constructed with porcine saphenous vein graft (SVG) using ICG.

Purpose: We investigated the feasibility and advantages of using non-contrast CT calcium score (CTCS) images to assess pericoronary adipose tissue (PCAT) and its association with major adverse cardiovascular events (MACE). PCAT features from coronary computed tomography angiography (CCTA) have been shown to be associated with cardiovascular risk but are potentially confounded by iodine. If PCAT in CTCS images can be similarly analyzed, it would avoid this issue and enable its inclusion in formal risk assessment from readily available, low-cost CTCS images.

BACKGROUND Coronary artery ectasia (CAE) is frequently present with coronary artery disease (CAD). However, it is not clear why some patients with CAD progress to CAE while others do not. The pathogenesis of CAE is still poorly elucidated.

Local hemodynamics play an essential role in the initiation and progression of coronary artery disease. While vascular geometry alters local hemodynamics, the relationship between vascular structure and hemodynamics is poorly understood. Previous computational fluid dynamics (CFD) studies have explored how anatomy influences plaque-promoting hemodynamics.

Background: As percutaneous therapeutic options expand, the optimal management of severe aortic stenosis (AS) and concomitant coronary artery disease (CAD) is being questioned between coronary artery bypass grafting and surgical aortic valve replacement (CABG+SAVR) versus percutaneous coronary intervention and transcatheter aortic valve replacement (PCI+TAVR). We sought to compare perioperative and longitudinal risk-adjusted outcomes between patients undergoing CABG+SAVR versus PCI+TAVR.
Methods: Using the United States Centers for Medicare and Medicaid Services inpatient claims database, we evaluated all patient age 65 and older with AS and CAD undergoing CABG+SAVR or PCI+TAVR (2018-2022).
