"There is a male predilection (M:F = 3-4:1) 13. They are relatively more common in Eastern and Asian populations and can occur in any age group, with a mean age of presentation at 35 years 4."
"In congenital cases, they most often involve the right coronary sinus (~80%; rang 70-90% 11), less frequently the non-coronary sinus (~17.5%; range 10-25%), and rarely left coronary sinus ("

"Filling of the aneurysm may be observed with colour flow Doppler, and the use of contrast may aid in the visualisation of the left-to-right shunt, as well as differentiating between ruptured and unruptured aneurysms 9. The use of spectral Doppler allows quantification of flow velocity and direction; rupture into a cardiac chamber with subsequent shunting typically yields constant flow from the aorta to the lower pressure chamber throughout the cardiac cycle, potentially allowing differentiation from other intracardiac shunts, e.g. ventricular septal defects 10."
