Background: Intra-atrial right coronary artery (RCA) is a rare and generally asymptomatic anomaly of development of the coronary arteries. This malformation could potentially expose the patient to a catastrophic outcome in the case of injury during interventional or surgical procedures. Currently, only a few case reports and no systematic reviews are available in the literature.
Case Summary: We report the case of a 54-year-old man with atypical chest pain who underwent multi-detector computed tomography angiography (MDCTA). The exam revealed no significant coronary artery stenoses; however, an intra-atrial course of mid RCA was evident. Medical therapy was administered, and the patient was discharged to home without undergoing a conventional angiography. Previously reported autoptic and clinical cases were retrieved from the PubMed literature database to compare the clinicopathological features of this case.
Conclusion: MDCTA depicted the abnormal course of the coronary artery in this patient as an intra-atrial course of the mid RCA. Finding this abnormality was crucial to avoid an inadvertent injury during interventional or surgical procedures.

The coexistence of anxiety or depression with coronary heart disease (CHD) is a significant clinical challenge in cardiovascular medicine. Recent studies have indicated that hypothalamic-pituitary-adrenal (HPA) axis activity could be a promising focus in understanding and addressing the development of treatments for comorbid CHD and anxiety or depression. The HPA axis helps to regulate the levels of inflammatory factors, thereby reducing oxidative stress damage, promoting platelet activation, and stabilizing gut microbiota, which enhance the survival and regeneration of neurons, endothelial cells, and other cell types, leading to neuroprotective and cardioprotective benefits.

Background: Contemporary surgical approaches for aortic valve replacement (AVR) include full median sternotomy, hemi-sternotomy, and a right anterior mini thoracotomy (RAMT) approach. We report the midterm outcomes of RAMT for isolated AVR.
Methods: A retrospective study was conducted, reporting the midterm outcomes of patients who underwent isolated RAMT AVR.

Background: Coronary artery bypass grafting (CABG) surgery has been a widely accepted method for treating coronary artery disease. However, its postoperative complications can have a significant effect on long-term patient outcomes. A retrospective study was conducted to identify before and after surgery that contribute to postoperative stroke in patients undergoing CABG, and to develop predictive models and recommendations for single-factor thresholds.

Objective: This study compared the value of different systemic immune-inflammatory markers for evaluating coronary collateralization (CC) in patients with type 2 diabetes mellitus (T2DM) and chronic total occlusion (CTO).
Methods: Systemic immune-inflammation index (SII), systemic inflammation response index (SIRI) and pan-immune-inflammation value (PIV) were calculated at admission in 1409 T2DM patients with CTO. The degree of coronary collaterals was estimated using the Rentrop scoring system and categorized into poor (Rentrop score 0 or 1) or good (Rentrop score 2 or 3) CC.
This case emphasizes the rare occurrence of Takotsubo cardiomyopathy (TTC) in a patient with moderate coronary artery disease (CAD), highlighting the complexity of diagnosis and management. Clinicians should maintain a high index of suspicion for TTC in patients with CAD, especially when echocardiographic findings suggest apical ballooning. Balancing therapies for both conditions is essential.
