This can lead to the subsequent displacement of the papillary muscles and the dilatation of the mitral valve annulus.
12.
The papillary muscles of both the right and left ventricles begin to contract shortly before ventricular systole and maintain tension throughout.
13.
Rupture of the papillary muscle may also lead to acute mitral regurgitation and subsequent pulmonary edema and possibly even cardiogenic shock.
14.
This shortcut across the chamber of the ventricle seems to facilitate conduction time, allowing coordinated contraction of the anterior papillary muscle.
15.
Unique to the parachute mitral valve is that the chordae insert on one papillary muscle, rather than two distinct papillary muscles.

17.
Ischemic heart disease causes MI by the combination of ischemic dysfunction of the papillary muscles, and the dilatation of the left ventricle.
18.
During the relaxation phase of the cardiac cycle, the papillary muscles are also relaxed and the tension on the chordae tendineae is slight.
19.
So by the action of papillary muscles on the atrioventricular valves, backflow of the blood from the ventricles into the atria is prevented.
20.
It arises from the lower part of the interventricular septum and crosses the interior space of the right ventricle to connect with the inferior papillary muscle.
