Visualization of the Coronary Sinus in Cineangiocardiography [PDF]
Circulation, 1955 Reflux opacification of the coronary sinus was observed in 25 of 100 cases examined by cineangiocardiography. Of the 25 coronary sinus "positive" cases, 88 per cent were found to have cardiovascular lesions which are regularly associated with severe hypertension of the right heart chambers.

Principal component analysis of atrial fibrillation: Inclusion of posterior ECG leads does not improve correlation with left atrial activity [PDF]
, 2015 Background Lead V? is routinely analysed due to its large amplitude AF waveform. V? correlates strongly with right atrial activity but only moderately with left atrial activity. Posterior lead V? correlates strongest with left atrial activity.

An unusual cause of atrial fibrillation in a young active duty soldier
Radiology Case Reports, 2017 Coronary artery fistula (CAF) is an abnormality in which the coronary artery has an anomalous connection with a venous structure such as the coronary sinus or atrium. CAF is usually congenital, but may be acquired.

In vivo dose measurement using TLDs and MOSFET dosimeters for cardiac radiosurgery. [PDF]
, 2012 In vivo measurements were made of the dose delivered to animal models in an effort to develop a method for treating cardiac arrhythmia using radiation. This treatment would replace RF energy (currently used to create cardiac scar) with ionizing radiation.

Effect of Bileaflet Valve Orientation on the 3D Flow Dynamics in the Sinus of Valsalva
Journal of Biomechanical Science and Engineering, 2011 Three-dimensional (3D) evolutional behavior of flow dynamics in the aortic sinus of Valsalva was studied in vitro for finding the effects of bileaflet valve orientations in an effort to investigate possible linkages between the sinus flow and coronary ...

Effects of pressure-controlled intermittent coronary sinus occlusion on regional ischemic myocardial function [PDF]
, 1985 Pressure-controlled intermittent coronary sinus occlusion has been reported to reduce infarct size in dogs with coronary artery occlusion, possibly because of increased ischemic zone perfusion and washout of toxic metabolites.
