Ebstein's Anomaly


This abnormality is congenital in nature. This is an example of Ebstein's Anomaly as heard at the tricuspid area. The first heart sound is increased due to thickening of the tricuspid valve leaflets. The second heart sound is normal. A rectangular murmur of tricuspid regurgitation fills all of systole. An opening snap occurs 100 milliseconds into diastole followed by a decrescendo-crescendo murmur of mitral stenosis. These findings are all a manifestation of downward displacement of the tricuspid valve into the right ventricle The person with Ebstein's Anomaly will have the enlarged right atrium and the small right ventricle.
