How Useful Is Transoesophageal Echocardiography During Electrical Cardioversion for Predicting Long-Term Sinus Rhythm Maintenance?

Abstract

Both pharmacological and electrical cardioversion are widely used in the management of subjects affected by atrial fibrillation (AF). The tachyarrhythmia recurrence rate after restoration of sinus rhythm (SR) is near 40% [1], and about 57% of cases occur during the first 30 days [2]. This cardiac arrhythmia has a deep impact on patient’s haemodynamics and risk of embolic events, so tailored antiarrhythmic and anticoagulant therapy is commonly employed [3] even though it is not free of complications. Many authors have tried to identify predictors of AF reversibility and SR maintenance. Formerly clinical features of the patients affected were focused on [4]. Later, after the introduction of transthoracic echocardiography (TTE), a correlation was established between left atrial (LA) size and AF recurrence [5]. TEE has allowed investigation of the anatomical and functional aspects of the left atrial appendage (LAA) during AF, and it was documented that auricular Doppler flow patterns constitute a predictor of embolic events [6], successful cardioversion [7] and maintenance of SR [8].
