A 14-year-old male patient presented with cyanosis and tiredness. The patient had undergone a Glenn procedure at age 12 following the echocardiographic determination of a double inlet left ventricle, ventriculoarterial discordance, moderate valvular-subvalvular pulmonary artery stenosis, non-restrictive inlet ventricular septal defect and right ventricle hypoplasia; his oxygen saturation was 70...

In the article by Huang et al, “Association of Rate-Dependent Conduction Block Between Eccentric Coronary Sinus to Left Atrial Connections with Inducible Atrial Fibrillation and Flutter”, which published online on December 30, 2016, and appeared in the January 2017 issue of the journal (Circulation: Arrhythmia and Electrophysiology. 2017;10:e004637. DOI: 10.1161/CIRCEP. 116.004637, corrections ...

Coronary sinus oxygen saturation was measured continuously during incremental atrial pacing in 34 patients undergoing cardiac catheterisation. In eleven patients with normal coronary arteriograms, negative exercise tests, and no ST segment depression on the electrocardiogram, an increase in the rate of atrial pacing transiently decreased coronary sinus oxygen saturation but within 20 s oxygen s...

BACKGROUND Gender-specific differences in cardiovascular risk are well known, and current evidence supports an existing role of endothelium in these differences. The purpose of this study was to assess non invasively coronary endothelial function in male and female young volunteers by myocardial blood flow (MBF) measurement using coronary sinus (CS) flow quantification by velocity encoded cine ...

BACKGROUND Cardiac troponin is a specific biomarker for cardiomyocyte necrosis in acute coronary syndromes. Troponin release from the coronary circulation remains to be determined because of the lower sensitivity of the conventional assay. We sought to determine basal and angina-induced troponin release using a highly sensitive troponin assay. METHODS AND RESULTS The cardiac troponin T levels...

A 27-year-old male, admitted to hospital for a psoas muscle abscess secondary to Crohn's disease, suddenly died while in hospital. A medicolegal autopsy showed coronary sinus thrombosis. Coronary sinus thrombosis is rare and is usually associated with invasive cardiac procedures. Coronary sinus thrombosis associated with Crohn's disease has not been reported. Autopsy examination of the coronary...

Dear Editor, We read with interest the article of Chou et al. (1). The authors reviewed the multidetector computed tomography (CT) findings of congenital coronary sinus anomalies and reported two cases of coronary sinus anomaly. We would like to share our observations, with respect to coronary sinus anomalies, with our colleagues. For better clinical outcomes, coronary venous variations should ...

BACKGROUND This study determined the histological features of the atrial myocardium connecting the coronary sinus and the left atrium in humans. METHODS AND RESULTS Ten necropsied hearts were studied by performing serial longitudinal sections parallel to the long axis of the coronary sinus that extended its full length using a large microtome. In all specimens, the venous wall of the coronary...

Coronary sinus (CS) pacing has been shown to prevent induction of atrial fibrillation (AF) by suppression of the propensity of atrial premature beats at high right atrium (HRA) to induce local conduction delay at the posterior triangle of Koch. However, other mechanisms of CS pacing in preventing induction of AF have not been explored. This study investigated whether a differential conduction d...

BACKGROUND Despite increasing clinical use, there is limited data regarding regadenoson in stress perfusion cardiovascular magnetic resonance (CMR). In particular, given its long half-life the optimal stress protocol remains unclear. Although Myocardial Perfusion Reserve (MPR) may provide additive prognostic information, current techniques for its measurement are cumbersome and challenging for ...
