Coronary venous anatomy and anomalies 3.1 Coronary sinus The coronary sinus (CS) is a tubular venous structure sitting in the inferior portion of the left atrioventricular groove that receives blood from many tributary veins before emptying into the posteromedial right atrium (Fig. 2). It is the ...
Coronary sinus (CS) is the largest coronary vein that receives blood from all the venous tributaries of the heart. Its variations in anatomy are significant from the surgical point of view, especially in patients with complex congenital heart diseases (CHDs). CS anomalies are rare, but with ...

(MBF) distributions11,12. Imaging the coronary anatomy and MBF can be performed using a single CT imaging modality, and this has been used to diagnose CAD16,17,18,45. Since the myocardium is perfused by upstream coronary arteries, the myocardial flow distribution can be used to infer ...
All patients were in normal sinus rhythm and were capable of the breath hold needed for CCTA. Patients with heart rates >70 beats/min were given 5-mg intravenous metoprolol at 5-min intervals to a total dose of 25 mg. If the patient’s heart rate did not drop below 70 beats/min, ...

The CCTA demonstrates a large fistula between the proximal left anterior descending coronary artery (LAD) (Figure 1) and great cardiac vein (GCV). The left main coronary artery, LAD and GCV are aneurysmal secondary to the fistula. The markedly dilated GCV drains in to the coronary sinus (Figu...
When the SCA originates from the right coronary sinus, identifying the abnormal course of the LAD is critical, as it may be life-threatening. In addition to CA, CCTA plays a key role in evaluating the anatomy and associated risks of this anomaly. The appropriate treatment is determined based...
The rightcoronary arteryoriginates from the right sinus of Valsalva and continues in the right atrioventricular groove to the crux of the heart. Its ostium is usually in the upper two thirds of the sinus but may be ectopically located from slightly below theaortic valveleaflets in theleft ventri...
