title: Posteromedial papillary muscle rupture due to squeezing of the left anterior descending coronary artery.
abstract: An unusual case of posteromedial papillary muscle (PPM) rupture due to isolated left anterior descending (LAD) artery ischaemia, associated with severe myocardial bridge contraction, is presented. The unusual blood supply to the PPM was associated with its apical origin and apex-forming LAD.
