Review Case Reports
[The case of left atrial myxoma originating from posterior leaflet of mitral valve].
We experienced the case of left atrial myxoma originating from posterior leaflet mitral valve. Mitral valve repair was performed in that case, because of the presence mitral leaflet defect due to removal of the myxoma. Transesophageal echocardiography was a useful tool for perioperative evaluation of the mitral valve and precise localization of the origin of the myxoma.

Case Reports
[A case of an adult patient of tetralogy of Fallot having malignant hyperthermia during surgery].
An episode of malignant hyperthermia occurring in a 42-year-old man undergoing hypothermic cardiopulmonary bypass is reported. Malignant hyperthermia is a syndrome initiated by a hypermetabolic state of skeletal muscle. ⋯ And the disease of tetralogy of Fallot made the syndrome difficult to manage. Although the clinical diagnosis of malignant hyperthermia is difficult to be confirmed, when it is suspected, it is prudent for the case to be initially treated as malignant hyperthermia.
