Progressive Acute Lower Extremity Ischemia Resulting From Cardiac Myxoma Embolization: A Case Report.

Cardiac myxomas are the most common primary benign tumors of the heart. The occlusion of peripheral arteries and complete obstruction of the abdominal aorta by a tumor embolus presents with distinct clinical manifestations. Herein, we present the case of a 38-year-old male with acute paresthesia, muscle weakness, erythematous, and violaceous changes in skin color localized to the dorsum of the left forefoot initially treated as cutaneous vasculitis.

Rare Presentation of Endocarditis and Mycotic Brain Aneurysm.

Bartonella endocarditis can be an elusive diagnosis. The clinical manifestations can vary and, at times, include multiorgan involvement. This case report describes 2 patients who presented with multiorgan failure, cerebral mycotic aneurysms, and valvular endocarditis secondary to Bartonella infection.

Anomalous Aortic Origin of a Coronary Artery.

Anomalous aortic origin of a coronary artery (AAOCA) is the second leading cause of sudden cardiac death in young athletes. The pathophysiology leading to sudden cardiac death, the specific risks associated with the different varieties of AAOCA, and the effects of different management strategies on the risk of sudden cardiac death are all unknown. This article describes the current knowledge of AAOCA, a proposed nomenclature for the different anatomic subtypes, the different modalities used to diagnose and characterize the disease, the available management strategies, and an algorithm used by the authors to diagnose and manage these patients.
