ACUTE TRIAL
Use of transesophageal echocardiography to guide cardioversion in patients with atrial fibrillation
multicenter, prospective, randomized controlled trial
Objective: To compare conventional anticoagulation strategy with the transesophageal echocardiography to guide short-term anticoagulant therapy in patients with atrial fibrillation prescribed with electrical cardioversion
1222 patients
Inclusion criteria: Patients aged ≥18 years who had atrial fibrillation of more than 2 days duration or who had atrial flutter with history of atrial fibrillation.

Conclusion: The use of transesophageal echocardiography to guide the management of atrial fibrillation may be considered a clinically effective alternative strategy to conventional therapy for patients in whom elective cardioversion is planned.
