Redo mitral valve replacement with annular reconstruction of left atrial dissection following mitral valve replacement for infective endocarditis: a case report.

Background: Left atrial dissection is a rare and occasionally fatal complication of cardiac surgery and is defined as the creation of a false chamber through a tear in the mitral valve annulus extending into the left atrial wall. Some patients are asymptomatic, while others present with various symptoms, such as chest pain, dyspnea, and even cardiac arrest. Although there is no established management for left atrial dissection, surgery should be considered in patients with hemodynamic disruption.

[Refractory Hypertension and Intermittent Claudication Caused by Distal Elephant Trunk Stenosis 10 Years After Total Arch Replacement for Stanford Type A Aortic Dissection;Report of a Case].

A 49-year-old man was admitted to our hospital because of intermittent claudication and refractory hypertension 10 years after surgery to Stanford type A acute aortic dissection. He underwent total arch replacement with an elephant trunk of 22 mm in diameter. Transesophageal echocardiography revealed that distal end of the elephant trunk was stenosed.
