We herein report a case in which a right coronary to coronary sinus arteriovenous fistula determined progressive aneurysmatic dilatation of the coronary sinus. Severe compression of the left atrium ensued. This led to a clinical and instrumental picture similar to that observed in severe mitral stenosis.

The impact of new-onset atrial fibrillation in the setting of acute coronary syndrome.

J Cardiol

Tianjin Key Laboratory of Ionic-Molecular Function of Cardiovascular Disease, Department of Cardiology, Tianjin Institute of Cardiology, Second Hospital of Tianjin Medical University, Tianjin, China; Kent and Medway Medical School, Canterbury, Kent, UK; School of Nursing and Health Studies, Hong Kong Metropolitan University, Hong Kong, China.

Approximately 10 % of patients who have suffered from myocardial infarction develop new-onset atrial fibrillation (AF). Coronary artery disease implicating atrial branches has been associated with AF. The following variables have been associated with new-onset AF in the setting of acute coronary syndrome: older age, history of hypertension, history of angina, history of stroke, chronic renal failure, body mass index, no statin use, worse nutritional status, worse Killip class, admission heart rate ≥ 85 bpm, complete atrioventricular block, Glasgow prognostic score, Syntax score, CHEST score > 3, PRECISE-DAPT score ≥ 25, left ventricular ejection fraction ≤40 %, increased left atrial diameter, E/E' ratio > 12, epicardial fat tissue thickness, and thrombolysis in myocardial infarction flow <3.

BACKGROUND A single coronary artery is a rare congenital anomaly of the coronary arteries distribution, with an incidence of only 0.03% in the general population undergoing coronary angiography. RCA arising from the distal circumflex artery is an extremely rare variety.

Objective: Etrasimod is an oral, once-daily, selective sphingosine 1-phosphate (S1P) receptor modulator for the treatment of moderately to severely active ulcerative colitis (UC). S1P receptor expression on cardiac cells is involved in cardiac conduction. We report cardiovascular treatment-emergent adverse events (TEAEs) associated with S1P receptor modulators and other cardiovascular events in the etrasimod UC clinical programme.

High takeoff of the right coronary artery by echocardiography: normal variant or something more?

Cardiol Young

January 2025

Congenital Heart Center, Division of Pediatric Cardiology, Department of Pediatrics, University of Florida, Gainesville, FL, USA.

Purpose: High takeoff of the right coronary artery suspected by echocardiography is widely considered a normal variant. However, in our experience, some patients initially thought to have a high takeoff of the coronary artery were later found to have an anomalous coronary origin with high-risk features. The aim of this study was to test the hypothesis that high takeoff of the right coronary artery suspected by echocardiography may indicate the presence of an anomalous coronary artery lesion with an intramural course requiring further investigation.

Patients with anomalous coronary artery origins (AOCA) exhibit a higher risk of atherosclerosis, where even minimal stenosis may lead to adverse cardiovascular events. However, the factors contributing to this heightened risk in AOCA patients remain unclear. This study aimed to investigate whether an AOCA patient is more prone to stenosis occurrence and its progression in view of hemodynamics.
