Emergent bedside real-time three-dimensional transesophageal echocardiography in a patient with cardiac arrest following a caesarean section.

Post-caesarean pulmonary embolism (PE) is associated with significant peri-operative morbidity and mortality. This report describes a case of sudden cardiac arrest 2 days post-caesarean due to massive PE diagnosed via bedside transesophageal echocardiography (TEE). Recognition of the PE at the bifurcation of the right and left pulmonary arteries was achieved by real-time three-dimensional TEE, but not two-dimensional TEE. Extracorporeal membrane oxygenation was immediately established and emergent pulmonary thromboembolectomy was performed. The patient was discharged without residual deficits on Day 22 of hospitalization.
