Malignant Hyperthermia: Report of Two Cases with a Neglected Complication in Cardiac Surgery.

Malignant hyperthermia (MH) can develop after contact with volatile anesthetics (halothane, enflurane, isoflurane, sevoflurane, and desflurane) as well as succinylcholine and cause hypermetabolism during anesthesia, which is associated with high mortality when untreated. Early diagnosis and treatment could be life-saving. During cardiac surgery, hypothermia and cardiopulmonary bypass make the diagnosis of MH extremely challenging compared with other settings such as general surgery.

Evaluation of Early and Intermediate Outcomes of Cryo-MazeProcedure for Atrial Fibrillation.

Introduction: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in patients with mitral valve disease affecting 50% of patients undergoing mitral valve surgery, contributing to increased risks of systemic embolization, anticoagulant- related hemorrhage and mortality. The maze procedure is an effective way to treat AF. Over the last several years, cryoablation was substituted for atrial incision in many reports to simplify the maze procedure.
