Among the diagnostic techniques are: It is initially treated with medications, including diuretics, and medications for blood pressure control.

Right coronary artery Right coronary artery In the coronary circulation, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the heart. It travels down the right coronary sulcus, towards the crux of the heart. It branches into the posterior descending artery and the right marginal artery. Although rare, several anomalous courses of the right coronary artery have been described including origin from the left aortic sinus. At the origin of the RCA is the conus artery. In addition to supplying blood to the right ventricle (RV), the RCA supplies
