Summary: Anomalous origin of the right coronary artery from the opposite sinus with interarterial course (right-ACAOS) has been associated with increased risk of sudden cardiac death. A study examining patients undergoing coronary computed tomography angiography (CCTA) identified a prevalence of 0.26% for right-ACAOS with IAC, with predominantly asymptomatic patients managing well with conservative treatment. Further research is needed to determine the optimal medical follow-up for this condition.

Summary: Anomalous aortic origin of right coronary artery (AAORCA) is a congenital heart lesion that can lead to coronary ischemia and sudden death. This study analyzed patients with AAORCA managed at the center, finding that 30% underwent surgical management while 70% were monitored nonsurgically. The outcomes in the midterm were excellent with functional testing showing no evidence of ischemia in the surgical patients.

Summary: This study evaluates the changing ostial location of right coronary artery with anomalous origin from the left coronary sinus throughout the cardiac cycle and identifies high ostial location in the systolic phase as an independent predictor of major adverse cardiac events (MACE).

Summary: Congenital coronary anomalies can be incidentally found in adults, and an interarterial course of an anomalous coronary artery is considered malignant with a high risk of sudden cardiac death. This article reports a rare case of an anomalous origin of the right coronary artery presenting with vague symptoms without any evidence of inducible ischemia. Based on currently available data, it is difficult to determine the implications of this congenital anomaly on physical activity, treatment options, and estimating the risk of sudden cardiac death.

Summary: The anomalous aortic origin of the right coronary artery (AAORCA) is a congenital anomaly affecting the origin and course of the right coronary artery, which can be easily diagnosed using cardiac imaging modalities. Most patients are asymptomatic, but some, especially young athletes, may experience symptoms.

Summary: This study characterized anomalous aortic origin of coronary artery (AAOCA) in a large single-center adult cohort, finding that most patients were diagnosed in the presence of cardiac symptoms, 22% of patients underwent surgical repair with no deaths occurring during a median follow-up of 2.5 years. Anomalous right coronary arteries were diagnosed at an older median age compared to anomalous left main coronary arteries.

Summary: This study investigated the clinical characteristics and outcomes of 3 different subtypes of anomalous aortic origin of the left coronary artery (AAOLCA). The study found that all 3 subtypes of AAOLCA had inducible ischemia, while most cases of aborted sudden cardiac death occurred in interarterial AAOLCA (group 1). Therefore, a systematic approach is necessary to risk stratify AAOLCA patients.

Summary: Anomalous aortic origin of a coronary artery (AAOCA) is considered a major cause of sudden cardiac death (SCD) in children, especially anomalous left coronary artery (ALCA). We reported a rare case of AAOCA in which the coronary artery originated from an inappropriate location in the sinus of Valsalva and developed an intramural course, leading to severe myocardial infarction during exercise.

Summary: Current recommendations for AAOCA focus on surgical repair to prevent sudden cardiac death, but decision-making may vary in adults, especially for those with right AAOCA. Surgical treatment for right AAOCA patients with ischemic symptoms or myocardial ischemia is often met with reluctance.

Summary: Coronary artery anomalies refer to a group of congenital variations in the coronary arteries. One common variant is the anomalous aortic origin of a coronary artery, where a coronary artery arises from an inappropriate sinus of Valsalva. While most patients do not experience symptoms, these congenital variants can increase the risk of symptoms and even sudden cardiac death (SCD). Unfortunately, there is no consensus on how to assess and manage patients with these congenital variants. In this study, we present two unique cases of symptomatic anomalous right coronary arteries and discuss their clinical presentations, imaging findings, and management.

This report presents a case of a 40-year-old male with persistent tachycardia and decreased left ventricular ejection fraction. Concerns were raised about tachyarrhythmia-induced cardiomyopathy related to anatomical variations.

Summary: This study compared the efficacy and safety of edoxaban with warfarin in patients early after surgical bioprosthetic valve implantation or valve repair. The results showed that edoxaban is noninferior to warfarin for preventing thromboembolism and is potentially comparable for risk of major bleeding.

Summary: This study aimed to compare postoperative changes in lung volume and perfusion between patients undergoing lobectomy and limited resection for lung cancer, as well as to assess associations with tumor location. The results showed that patients who underwent lobectomy had greater increases in lung volume and perfusion ratios compared to those who underwent limited resection. In conclusion, these findings have important clinical implications for understanding the physiological effects of lung cancer surgery.

Summary: This decision analytical modeling study found that the deep learning-based synthetic bone-suppressed (DLBS) model exhibited higher sensitivity for detecting pulmonary nodules on chest radiographs compared with the original model. These findings suggest that the DLBS model could be beneficial to radiologists in the detection of lung nodules in chest radiographs without the need for specialized equipment or increased radiation dose.

Summary: We compared the diagnostic performance, costs, and association with major adverse cardiovascular events (MACE) of clinical coronary computed tomography angiography (CCTA) interpretation and a semiautomated artificial intelligence and machine learning approach (AI-QCT) for atherosclerosis imaging. The use of AI-QCT significantly reduced the rates and costs of invasive coronary angiography (ICA) in stable patients referred for nonemergent ICA, with no change in 1-year MACE.

Summary: This study introduces radiomic feature reproducibility analysis as an evaluation metric for computed tomography (CT) denoising algorithms and proposes a low-dose CT denoising method based on a generative adversarial network (GAN) that outperforms well-known CT denoising methods. Results show that traditional image assessment metrics fail to accurately evaluate the performance of CT denoising methods, while radiomic feature reproducibility analysis provides more distinctive assessment results. The study demonstrates that a well-tuned GAN architecture outperforms commonly used CT denoising methods and bridges the gap between traditional objective and subjective evaluations in the clinical medical imaging field.

Summary: This study aimed to compare the effects of a dual-source CT scanner without heart rate control and a single-source CT scanner with heart rate control on coronary CTA in the emergency department. The results showed that patients who underwent CTA using the dual-source CT scanner had shorter CT completion time, better image quality, and lower frequency of nondiagnostic examinations. Therefore, the use of a dual-source CT scanner can expedite clinical processes in the emergency department.
