The study was carried out on 80 human hearts (64 male and 16 female). The whole material has been divided into 4 groups: I - aged 19-40; II - aged 41-50; III - aged 51-60 and IV - aged 61-70. The venous vascular bed of 80 hearts was injected through the coronary sinus with Duracryl plus (Spofa Dental, Czech Republic) and next corroded. Thus obtained specimens were measured using electronic caliper (MAU-a E 0-150, Horex, Poland). The length of the coronary sinus varied from 15-50 mm (with the mean value of 30 mm in male hearts and 25 mm in female hearts). The caliber of the vessels varied from 7-13 mm. The length of the coronary sinus is not age-dependent, however it is longer in male than female hearts. Generally the caliber of male coronary sinus is bigger than in the female, although it isn't statistically significant.

Rationale: Quadricuspid aortic valve (QAV) is a rare condition with a very low incidence. Anomalous aortic origin of a coronary artery (AAOCA) is the most prevalent form of coronary anomaly. One variant of AAOCA is the anomalous aortic origin of the left coronary artery from the right coronary sinus (L-AAOCA).

Background: The role of a prothrombotic state in atrial fibrillation (AF) progression to permanent arrythmia (PerAF) is unclear. Formation of denser and poorly lysable fibrin clots has been observed in AF patients also with sinus rhythm in association with higher stroke risk. We investigated whether altered fibrin clot properties and other prothrombotic state markers may contribute to AF transition to PerAF.

Coronary sinus (CS) defects are rare congenital cardiac anomalies that occur in isolation or with other congenital heart diseases. Persistent left superior vena cava (LSVC) is a relatively common entity that usually drains into the CS, is of no hemodynamic consequence, and is easily diagnosed on echocardiography by a dilated CS and an antegrade flow toward the heart. However, a combination of LSVC and CS defect may reverse its flow direction and CS dilation may be absent.

A young female patient suffered cardiogenic shock after undergoing surgery for an ectopic pregnancy. Coronary artery computed tomography angiography (CTA) revealed a left main artery (LM) originating from the right coronary sinus and traveling between the aorta and pulmonary artery. We successfully resuscitated the patient with mechanical circulatory support using veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and an intra-aortic balloon pump (IABP).
