Case Reports[Bilateral coronary ostial stenosis after aortic valve replacement with freestyle stentless bioprosthesis: a case report].
An 80-year-old woman underwent aortic valve replacement with Freestyle stentless prosthetic valve for the stenosis. Four months later, she was admitted with myocardial ischemia. Coronary angiography revealed severe stenosis in the ostium of both right and left coronary arteries. ⋯ These clinical, angiographical histological and intravascular ultrasonography findings suggest that the immunological reaction to the heterograft was the mechanism of the bilateral ostial coronary arteries stenoses in the present case. The possibility of immunological reaction after aortic valve replacement with heterograft should be considered. There have been no report on intravascular echocardiographic and histological findings.

[Efficacy of transesophageal echocardiography in patients with cardiac arrest or shock].
Only a few examinations are available to critically ill patients. We assessed the efficacy of transesophageal echocardiography (TEE) in the management of patients with cardiac arrest or shock. ⋯ TEE is feasible even in patients with cardiac arrest or shock, and can play an important role in establishing the diagnosis and determining the treatment of such patients.
