Chordae rupture is the most common cause of severe acute mitral insufficiency. Many different mechanisms can cause an acute chordal rupture: degenerative mitral valve disease, infective endocarditis, myocardial infarction, or a posttraumatic event. We present 2 cases of acute mitral regurgitation requiring urgent surgery due to a posterior leaflet chorda rupture after extreme physical exercise.References
