A venous sinus opening into the heart's right atrium which drains the cardiac veins.

Coronary sinus atrial septal defects (ASDs) are defects located in the portion of the atrial septum that includes the coronary sinus orifice.
The explanation for this difficulty is that the ostium of the coronary sinus is not aligned with the tricuspid orifice and that a loop must be made before a lead can pass the tricuspid valve.
90% of the fistulas drain into venous circulation, including right-sided chambers (40%), pulmonary artery (15-20%), coronary sinus (7%) and superior vena cava (1%).
Also, a dilated coronary sinus may be misdiagnosed as an ostium primum atrial septal defect at the level of the opening of the coronary sinus into the right atrium (10).
A dilated coronary sinus (CS) is the first clue on echocardiography.
Among the 18 cases that originated from the LCA, 11 (32.3%) cases originated from the LAD [Figure 1] and [Figure 4], three (8.8%) cases originated from the left main artery (LMA), two (5.9%) cases originated from the left circumflex artery (LCX) [Figure 3] and [Figure 5], and two (5.9%) cases originated from the left coronary sinus. Among the 12 cases that originated from the RCA, seven (20.6%) cases originated from the proximal RCA, two (5.9%) originated from the distal RCA [Figure 3], and three (8.8%) from the right coronary sinus.
The Carillon device is a fixed-length double anchor implant with mirror-image hoop-shaped helical anchors that can be deployed in the coronary sinus (CS) to provide external splinting of the mitral annulus region to the maximal possible extent.
Left-sided inferior vena cava (LSIVC) draining into persistent left superior vena cava (PLSVC) is a rare cause for coronary sinus (CS) dilatation, but CS dilatation is a well-known cause of PLSVC and can be detected on echocardiography.
INXN-4001 is being studied clinically to assess its safety and feasibility of minimally invasive retrograde coronary sinus infusion (RCSI) in left ventricular assist device (LVAD) patients.
[1-3] The most common congenital anomaly is separate origin of the left anterior descending artery and circumflex artery from the left coronary sinus. [4] The left main coronary artery or left anterior descending artery arising from the right coronary sinus of Valsalva and right coronary artery originating from the left coronary sinus of Valsalva may be associated with sudden cardiac death, hence deserve special attention.
Anomalous aortic origin of the right coronary artery (AAORCA) describes the abnormal location of the orifice of the right coronary artery (RCA) in the left coronary sinus, an abnormality shown to carry a risk of myocardial infarction and sudden death [6].
