Commotio Cordis 710 Lesson
The patient was supine during auscultation.
Description
This lesson presents commotio cordis, a condition is caused by blunt force trauma to the chest, such as a baseball batter being hit in the chest by a pitch. Severe damage to the right and left ventricles and mitral and tricuspid valves may result.
In this example, the trauma is limited to the mitral valve leaflets. Rupture of a chordae tendinae has occurred, resulting in a systolic murmur. The first half of the murmur is rectangular. It is followed by a decrescendo late systolic component which is produced by rapid filling of the left atrium due to torrential mitral regurgitation.
The auscultation position is the mitral valve area.
