ABSTRACTBackgroundThe literature contains a few studies that explore the possibility of assessing coronary artery disease (CAD) risk based on the angle between the coronary arteries and the bifurcation of the aorta.PurposeTo reveal the relationship between the angle of the right coronary artery and the aorta, as well as the bifurcation angle of the left main coronary artery, with the degree of plaque and stenosis in the right coronary artery, left main coronary artery, left anterior descending artery (LAD), and circumflex artery (Cx).Materials and MethodsThe coronary CT angiographies of 217 patients, taken due to suspected CAD at our institution between October 2023 and June 2024, were retrospectively evaluated. All CT images were analyzed at different times by two experienced radiologists using a specialized workstation. There was significant concordance between intraobserver and interobserver assessments. Multiplanar reconstruction (MPR) was performed to measure the angles.ResultsThe mean LAD–Cx angle measured by the first radiologist was 78.81 ± 30.54, while the second radiologist's measurement was 79.34 ± 30.62, demonstrating excellent agreement. The mean right coronary artery–aortic (RCA–Aortic) angle measured by the first radiologist was 96.21 ± 33.47, while the second radiologist's measurement was 96.75 ± 33.62, again demonstrating excellent agreement.ConclusionIn this study, no association was found between coronary artery angles and the presence of plaque or stenosis. Therefore, coronary artery angles should not be considered a reliable indicator of CAD risk. Instead, risk assessment should include other well‐established risk factors.

ABSTRACTFetomaternal hemorrhage (FMH) is the passage of fetal blood through the maternal circulatory system before or during delivery. Due to the nonspecificity of clinical manifestations, FMH is rarely diagnosed. When it occurs rapidly, it could have catastrophic consequences. Decreased fetal movements and a sinusoidal cardiotocographic (CTG) for more than 30 min are characteristic findings. This paper presents a case report of a 34‐year‐old woman at 38 + 4 weeks with reduced fetal movements and a sinusoidal CTG. An emergency cesarean section was performed, delivering a pale newborn with a hemoglobin of 4.3 g/dL. A comprehensive review of the available literature is then reported.
