Abstract

We present a case of severe refractory hypotension in a patient undergoing de-bulking liver resection for massive polycystic liver disease. Emergent trans-oesophageal echocardiography (TOE) revealed dynamic left ventricular outflow tract (LVOT) obstruction with systolic anterior motion (SAM) of the anterior mitral leaflet (AML). Notably, he had a structurally normal heart on pre-operative trans-thoracic echocardiography (TTE). Diagnosis of SAM by TOE, possible mechanisms and specific management of refractory hypotension in this context are discussed.

Keywords: Anaesthesia; hypotension; intraoperative monitoring; trans-oesophageal echocardiography.
