Lipoma of the interatrial septum in a patient with chronic atrial fibrillation: A case report.

The authors report on a 70-year-old woman with chronic atrial fibrillation that was hospitalized for digitalis intoxication and incidentally was found to have an interatrial lipoma. The diagnosis was established by transesophageal echocardiography, computed tomography (CT) scanning, and magnetic resonance imaging (MRI). Owing to the asymptomatic character and the benign nature of the tumor, a decision for conservative management was made.

Acute myocardial infarction after a European hornet sting--a case report.

The authors briefly describe an 87-year-old man who experienced an acute ST-elevation myocardial infarction in the context of an anaphylactic reaction caused by a European hornet (Vespa cabro linnaeus) envenomation. This unusual case highlights the potential cardiovascular complications associated with common insect stings such as those caused by hymenoptera. Thus, a thorough cardiovascular evaluation is essential in such cases since the vasoactive, inflammatory, and thrombogenic mediators of anaphylactic reactions may provoke myocardial ischemia.
