Oral amiodarone prophylaxis of atrial tachyarrhythmias after cardiac surgery is effective and may be safe overall and in important patient subgroups. Clinical Trials Registration ClinicalTrials.gov Identifier: NCT00251706.

These data uncover, for the first time, beneficial effects of ET receptor blockade on endothelial-dependent vasorelaxation in human IMA.

Death by neurologic criteria (DNC) requires coma, absent brainstem reflexes, and the inability to breathe independently during apnea testing (AT). For patients on extracorporeal membrane oxygenation (ECMO), this clinical determination is more challenging. Herein, we report the case of a patient with DNC on ECMO post cardiac surgery, highlighting various considerations to the process and modifications required for AT.

Cardiac myxoma is the most common primary neoplasm of the heart and arises from the endocardium as a polypoid mass, which is commonly seen in the left atrium. Glandular cardiac myxomas are extremely rare cardiac myxomas that contain glandular structures and the pathogenesis of the glandular differentiation is unknown. The present case study reports a case of glandular cardiac myxoma. The tumor was located in the left atrium without invasion of the myocardium. Microscopically, the myxoma contained well-formed mucinous glands in a background of classic cardiac myxoma. Immunohistochemically, the mucinous glandular cells were strongly positive for cytokeratin 7 (CK7) and partially positive for calretinin, but negative for CD34, CK20, D2-40, WT-1, and TTF-1. In conclusion, glandular cardiac myxoma is very rare and it is important to recognize this entity correctly so that it is not misinterpreted as secondary adenocarcinoma.
