1 Introduction A cardiac pseudoaneurysm is defined as a contained rupture of the myocardium by the pericardium [ 5 ]. This is differentiated by a true aneurysm that contains all layers of myocardial tissue. Pseudoaneurysms are commonly associated with myocardial infarctions, particularly of the inferior wall [ 9 ]. Pseudoaneurysms require surgical intervention and carry a high risk of rupture and mortality [ 19 ]. We present a case of a pseudoaneurysm arising from a bioprosthetic mitral valve that developed after a redo mitral valve replacement (MVR) that was treated with percutaneous closure.
