What factors may predict successful cardioversion and maintenance of sinus rhythm in patients with lone atrial fibrillation?
Factors that may predict successful cardioversion and maintenance of sinus rhythm in patients with lone atrial fibrillation include the prevalence of left atrial thrombus, the use of transesophageal echocardiogram, the left atrial appendage flow, electrical cardioversion outcomes, and stroke events. Studies have shown that transesophageal echocardiogram is mandatory in order to assess the risk of thrombus formation, which is essential in the risk stratification of patients prior to cardioversion. Additionally, left atrial appendage flow has been shown to be a predictor of long-term sinus rhythm maintenance in patients with non-valvular atrial fibrillation. Furthermore, the results of electrical cardioversion and the occurrence of stroke events in patients with atrial fibrillation may also provide insight into the likelihood of successful cardioversion and maintenance of sinus rhythm.
