Unicuspid aortic valves usually have incomplete fusion of all of the leaflets and exhibit aortic stenosis. The heart valves and the chambers are lined with endocardium.Heart valves separate the atria from the ventricles, or the ventricles from a blood vessel.Heart valves are situated around the fibrous rings of the cardiac skeleton.The valves incorporate flaps called leaflets or cusps, similar to a duckbill valve or flutter valve, which are pushed open to allow blood flow and which then close.

Arrows depict direction of blood flow through the defect between the aorta and right atrium. Ninety to 95% of these congenital aneurysms originates in the right or non-coronary sinus and project into the right ventricle or into the right atrium.

During the operation, we observed a 30 × mm ruptured aneurysm that arose from the non. Intraoperative transoesophageal echocardiography showed that the commissure between the right coronary and non-coronary cusp of the aortic valve was detached from the aortic wall, with resultant right coronary cusp prolapse and severe aortic regurgitation.

Focal atrial tachycardias (ATs) have a predilection for specific areas within the atrium, such as the crista terminalis, 1 pulmonary vein ostia, 2 near the tricuspid and mitral annulus, 3, 4 the ostium of the coronary sinus (CS), 5 and para-Hisian regions. Aneurysm arising in the non-coronary sinus almost all rupture into the right atrium, and those arising in the right coronary sinus generally communicate with the right ventricle and occasionally with the right atrium. The mitral valve is also called the bicuspid valve and the left atrioventricular valve.

For the echocardiographer looking down at the aortic valve in the short axis view, the non-coronary cusp will be in the 7 o’clock position, the right coronary cusp will be in the 11 o’clock position and the left coronary cusp will be in the 3 o’clock position. 1 However, echo images may be sub-optimal in older patients with high body mass indices. The final cusp is named the non-coronary cusp and is positioned posteriorly relative to the other two cusps.
