Article Abstract
Background: Isolated coronary arteriovenous fistulas are extremely rare, accounting for 0.08-0.4% of all congenital heart disease. Closure of the fistula is recommended in cases of large dimensions, relevant left-right shunt, or ischaemic events. Thrombosis of the coronary aneurysms may occur as a postoperative complication.
Case Summary: We report a case of a coronary fistula between the circumflex artery and coronary sinus with giant aneurysm. After a failed percutaneous closure attempt, the patient was surgically treated without major postoperative complications. Despite therapeutic anticoagulation and antiplatelet therapy, she presented at clinical follow-up with thrombosis of the dilated coronary artery without signs or symptoms of ischaemia.
Discussion: Management of coronary artery fistula may be challenging in cases in which initial percutaneous closure is unsuccessful. This particular case also highlights the importance of close follow-up, despite optimal therapy, to detect potentially lethal complications related to the low flow in the dilated coronary aneurysm.

Noninvasive Anatomical and Functional Imaging for Hemodynamic Relevance in Right Coronary Artery Anomalies.
JAMA Cardiol

Importance: Right anomalous aortic origin of a coronary artery (R-AAOCA) is a rare congenital condition increasingly diagnosed with the growing use of cardiac imaging. Due to dynamic compression of the anomalous vessel, invasive fractional flow reserve (FFR) during a dobutamine-atropine volume challenge (FFR-dobutamine) is considered the reference standard. A reliable alternative method is needed to reduce extensive invasive testing, but it remains uncertain whether noninvasive imaging can accurately assess the hemodynamic relevance of R-AAOCA.

Purpose Of Review: This review aims to characterize the known cardiovascular (CV) manifestations associated with inflammatory bowel disease (IBD) and the underlying mechanisms driving these associations.
Recent Findings: Gut dysbiosis, a hallmark of patients with IBD, can result in both local and systemic inflammation, thereby potentially increasing the risk of cardiovascular disease (CVD) in the IBD population. Micronutrient deficiencies, anemia, and sarcopenia independently increase the risk of CVD and are frequent comorbidities of patients with IBD.
Genetic variants in HSP40 co-chaperones modulate ischemic heart disease risk.

Background: The chaperoning system, which is responsible for protein homeostasis, plays a significant role in cardiovascular diseases. Among molecular chaperones or heat shock proteins (HSPs), the HSP40 family, the main co-chaperone of HSP70, remains largely underexplored, especially in ischemic heart disease (IHD) risk.
Materials And Results: We genotyped 834 IHD patients and 1,328 healthy controls for three SNPs (rs2034598 and rs7189628 DNAJA2 and rs4926222 DNAJB1) using probe-based real-time PCR.
Impact of diabetes on outcomes of patients with ST-segment elevation myocardial infarction and multivessel coronary artery disease undergoing percutaneous coronary intervention.

Background: Diabetic patients with ST-segment elevation myocardial infarction (STEMI) are at an increased risk of cardiovascular events as compared to non-diabetic patients. This analysis investigated outcomes of diabetic patients presenting with multivessel disease (MVD) and STEMI in a contemporary trial and the relevance of an immediate versus staged multivessel PCI strategy in this high-risk population.
Methods: Patients enrolled in the MULTISTARS AMI trial were stratified according to the presence/absence of diabetes.

Coronary artery bypass graft (CABG) surgery remains the gold standard of care to prevent myocardial ischemia in patients with advanced atherosclerosis; however, poor long-term graft patency remains a considerable and long-standing problem. Excessive vascular smooth muscle cell (SMC) proliferation in the grafted tissue is recognized as central to late CABG failure. We previously identified SMILR, a human-specific SMC-enriched long noncoding RNA that drives SMC proliferation, suggesting that targeting SMILR expression could be a novel way to prevent neointima formation, and thus CABG failure.
