Complete Heart Block Causing Takotsubo Syndrome: A Case Report.

The association of complete atrioventricular (AV) block with Takotsubo syndrome (TTS) is well known, but the cause-and-effect relationship has not been determined. We present the case of a 91-year-old female with complete AV block who went untreated for over a year and later developed Takotsubo syndrome. Reversal of wall movement defects was seen after a permanent pacemaker was implanted, and routine follow-up showed that the implanted pacemaker worked normally.

A Case of Bioprosthetic Mitral Valve Endocarditis with Severe Stenosis.

A 29-year-old female with a history of bioprosthetic mitral valve replacement was admitted with fever, chills, and shortness of breath of two weeks duration. Transthoracic echocardiography revealed a thickened bioprosthetic mitral valve with a 26 mmHg mean gradient consistent with severe mitral stenosis and associated large vegetation. Blood cultures demonstrated no growth.
