Abstract:
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.

Mitral Valve Prolapse I: Introduction
Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
