Primary Cardiac T-Cell Lymphoma Localized in the Mitral Valve.

Primary cardiac lymphoma is a rare cardiac tumor, and usually originates from B cells and involves the right side of the heart. We present an extremely rare case of primary cardiac T-cell lymphoma involving the mitral valve alone. A 58-year-old woman who was positive for human T-cell leukemia virus 1 underwent mitral valve replacement because of severe mitral regurgitation.

Ventricular fibrillation after bortezomib therapy in a patient with systemic amyloidosis.

A 64-year-old female was diagnosed with systemic amyloidosis associated with multiple myeloma. Bortezomib and dexamethasone-therapy was initiated; however, she developed lethal ventricular fibrillation (VF) and cardiac arrest after 84 hours of therapy. Cardiopulmonary resuscitation using direct current shocks with epinephrine and amiodarone was initiated but failed to receive cardiac function.
