The central orifice of the device remains patent and becomes the sole path for blood flow through the coronary sinus, leading to the development of an upstream pressure gradient that results in ...

The right coronary artery (RCA) arises further caudal, at the right aortic sinus. The RCA runs through the atrioventricular groove, encircling the tricuspid orifice, reciprocal to the LCX (Figure 4).

The coronary sinus (CS) refers to a collection of veins that join together to form a large blood vessel. This vein is located between the left atrium and the left ventricle of the heart.

Anomalous origination of a coronary artery from the opposite sinus (ACAOS) is estimated to be present in 0.2–2.0% of the population. In the majority of individuals, ACAOS has no hemodynamic or ...
