Ultrasonography showed anterolateral papillary muscle rupture (PMR) which caused anterior mitral leaflet prolapse and severe mitral valve regurgitation, and he successfully underwent mitral valve replacement. Anterolateral PMR causing anterior mitral leaflet prolapse due to obstruction of the first diagonal branch is rare and should be considered in such an AMI case.</span></p>}, number={6}, journal={The Heart Surgery Forum}, author={Kodama, Hiroshi and Takahashi, Shinya and Katayama, Keijiro and Sueda, Taijiro}, year={2017}, month={Dec.}, pages={E263-E265} }
