Attempted Non Triggering Anesthetic for Minimally Invasive Mitral Valve Repair in a Patient Highly Susceptible to Malignant Hyperthermia

Document Type

Conference Proceeding

Publication Date



A 51-year-old man with no past surgical history presented for evaluation of exertional dyspnea and fatigue. Echocardiography showed severe mitral regurgitation and no significant coronary artery disease was identified. After scheduling a minimally invasive mitral valve repair, the patient admitted a family history of malignant hyperthermia (MH) in both his father and sister after prior surgeries. A non-triggering anesthetic was attempted. This case will discuss the pathophysiology of MH in addition to proposing sound preoperative and intraoperative anesthetic plans for patients at significant risk of developing MH while undergoing complex cardiac surgery involving cardiopulmonary bypass.
