Parachute-like asymmetric tricuspid valve in an asymptomatic adult.
A parachute deformity of an atrioventricular valve occurs when the chordae tendineae arise from one papillary muscle or muscle group. Sometimes, the normal number of papillary muscles is seen, but one muscle is much larger than its peers and shows some characteristic features. This is known as a parachute-like asymmetric valve and has been well described in the mitral position. We present a young, asymptomatic adult with an abnormal tricuspid valve possessing typical features of a parachute-like asymmetric valve.
