Real-time identification of aetiology in patients able to undergo transoesophageal echocardiography with non-traumatic out-of-hospital cardiac arrest in China: a prospective, single-centre exploratory study

This study investigates the feasibility and effectiveness of transoesophageal echocardiography (TEE) in rapidly identifying reversible aetiologies during resuscitation of patients with non-traumatic out-of-hospital cardiac arrest (OHCA) in China. The authors found that TEE successfully provided diagnostic-quality images and identified aetiologies in 39% of cases, with acute aortic dissection being the most common. However, the study concludes that further controlled investigations are needed to establish TEE's role as a complementary tool in this context.
