A transthoracic echocardiogram (TTE) indicates if there is an aortic regurgitation, but a 3-D transesophageal echocardiogram can give a better view of the aortic valve.Multidetector coronary CT angiography has been indicated as a single competent diagnostic imaging tool capable of delineating valvular anatomy, severity of regurgitation, and high risk coronary problems. Classification
There have been seven described variations of the quadricuspid aortic valve. They are classified on a scale from A to G and describe the variations in size of the four cusps. The most common variation is that of B – three equal-sized cusps and one smaller cusp. There is no correlation between the anatomy and functional status of the aortic cusps. Treatment
The typical method of treatment is through surgery such as aortic valve reconstruction surgery (AVRS) and aortic valve replacement, usually with a synthetic valve. Incidence
Quadricuspid aortic valves are very rare cardiac valvular anomalies with a prevalence of 0.013% to 0.043% of cardiac cases and a prevalence of 1 in 6000 patients that undertake aortic valve surgery. There is a slight male predominance in all of the cases, and the mean age is 50.7. == References ==
