A Rare Ischemic Complication: Tricuspid Pillar Rupture after Anterior Myocardial Infarction

The rupture of the papillary muscle (PRM) after a myocardial infarction (MI) became rare since the introduction of primary angioplasty. In most cases in literature, it’s reported in the mitral valve. Followed by a PMR of the tricuspid valve (TV), which is extremely rare. We described a case of a 78-year-old patient, who was admitted to the emergency room for a delayed anterior ST elevation myocardial infarction. It was later complicated by papillary muscle rupture after a percutaneous coronary intervention (PCI) of the right coronary artery involving a stent. The patient underwent surgical repair of the TV with fatal evolution.
