This case report highlights that right ventricular myocardial infarction can lead to papillary muscle dysfunction and subsequent tricuspid incompetence.
May prompt consideration of papillary muscle dysfunction in post-RV MI tricuspid regurgitation; single case extends known complications but remains hypothesis-generating.
Summary There has recently been much interest in mitral incompetence as a result of papillary muscle damage in myocardial infarction. We report a case of tricuspid incompetence due to papillary muscle dysfunction following myocardial infarction involving the right ventricle.
