The Echo-of-the-Day is a presentation of one to four image or video loops to present an important topic in echocardiography. Please reveiw the image or video loops and then answer the questions below. After you have answered the questions you can view the explanation and obtain CME credit (if available).

Title: A Complete Circle
Date: 2010-09-09
Presentation: A patient presented with the following loops:
Explanation: The patient has pulmonary artery stenosis that is supravalvular from the pulmonary valve. The ring is intrinsic (extrinsic rings can cause extrinsic compression) and heavily calcified. The Vmax is 4 m/s for a peak PVG of 64 mmHg and a mean PVG of around 44 mmHg. Supravalvar pulmonary stenosis is often associated with rubella syndrome
and Williams syndrome (ie, elfin facies, supravalvar aortic stenosis,
and hypercalcemia with or without mental retardation). Supravalvular pulmonary stenosis can be congenital or as a result of a PDA, anomalous coronary artery repair or other conditions where surgery occurs near the pulmonary artery. Turner's syndrome usually has valvular PS although it can have supravalvular PS also.
The peak and mean gradient are high enough that excision of the pulmonary valve ring should be considered.
