Acute Myocardial Infarction in a Patient with Two-Vessel Occlusion and a Large Lambl’s Excrescence

Abstract EN

A 59-year-old man underwent an echocardiography study after myocardial infarction and it showed a thin, mobile mass attached to the aortic valve.

A diagnosis of Lambl’s excrescence (LE) was suspected.

Coronary occlusion as a consequence of embolism of LE’s material could not be excluded and the patient underwent surgical excision.

Histology confirmed the diagnosis; however a differential diagnosis with papillary fibroelastoma could not be established because both of these structures are histologically indistinguishable.

A brief survey of the literature is presented.

Evidence-based recommendations for treatment have not been established yet.
