Congenital coronary sinus anomalies are extremely rare, and they have received relatively little attention. This is probably due to the lack of both clinical symptoms and significant cardiac functional disturbance. We present two cases of a coronary sinus anomaly and briefly review the literature. Recognizing and being familiar with the variations of a congenital coronary sinus anomaly in conge...

Coronary anomalies are rare angiographic findings. Moreover, there are few reports of cases of an anomalous origin of the right coronary artery from the left sinus of Valsalva and of the left coronary artery from the posterior sinus of Valsalva. Here, we report a case with an anomalous origin of the right coronary artery from the ascending aorta above the left sinus of Valsalva and the left cor...

Coronary sinus blood flow was studied by the continuous thermodilution method in 13 subjects with normal coronary arteries and 14 patients with coronary artery disease during progressive elevation of the heart rate by atrial pacing. In 11 patients of the coronary group angina pectoris developed during pacing. In subjects with normal coronary arteries the coronary sinus blood flow rose proportio...

The changes in the coronary circulation, which are precipitated by the acute occlusion of the coronary sinus, have been investigated. In normal animals, retrograde blood emerging from the peripheral segment of a ligated and transected circumflex coronary artery is small in quantity, and arterial in nature, signifying an insignificant interarterial collateral flow. After the coronary sinus is ar...

BACKGROUND Up to 30% of patients with heart failure do not respond to cardiac resynchronisation therapy (CRT). This may reflect placement of the coronary sinus lead in regions of slow conduction despite optimal positioning on current criteria. OBJECTIVES To characterise the effect of CRT on left ventricular activation using non-contact mapping and to examine the electrophysiological factors i...

Total upper body drainage via left superior vena cava into coronary sinus (i.e. absent right superior vena cava) is a rare anomaly and distorts the anatomy of coronary sinus and triangle of Koch. Herewith we are reporting the first report of ablation in a patient with superior vena cava draining into coronary sinus totally. This patient with atrioventricular nodal re-entrant tachycardia, baseli...
