Flecainide-Induced Left Bundle Branch Block.

Flecainide is the first-line antiarrhythmic agent used in patients without structural heart disease. It is a class IC antiarrhythmic drug that inhibits inward sodium current through its dose-dependent blockade of voltage-gated calcium channels within the cardiac membrane. It has been shown to slow the conduction in the left bundle branch block.

Late Presentation of Massive Aortic Aneurysm with Aortic Regurgitation.

• Clinical manifestations of AR can vary widely. • Echocardiography is critical in diagnosis and surveillance of AR and aortopathy. • Aortic root aneurysm > 5.

A Case of Multiple Calcific Embolic Strokes in a Patient With a Porcelain Left Atrium.

Mitral annular calcification (MAC) commonly manifests as an incidental, asymptomatic finding that is associated with several cardiovascular risk factors, atherosclerosis, cardiovascular death, and all-cause mortality. Very rarely, patients with severe MAC can have extensive dystrophic calcification extending into the left atrial wall, termed porcelain left atrium. In this case report, we describe a patient who experienced multiple calcific acute embolic strokes in the setting of severe mitral annular calcification and porcelain left atrium.
