Increased left atrial size is associated with higher atrial fibrillation recurrence in patients treated with antiarrhythmic medications.

ABSTRACT:

Background

Atrial fibrillation (AF) is highly prevalent, and antiarrhythmic therapy is often used to help with rhythm control. Some common echocardiographic parameters may be useful in predicting AF recurrence among these patients. The purpose of this study was to evaluate the association between 3 common echocardiographic parameters (left atrial [LA] size, left ventricular ejection fraction [LVEF], and mitral regurgitation [MR]) and AF recurrence among patients treated with antiarrhythmic medications.

Hypothesis

We hypothesized that LA size, LVEF, and severity of MR are predictors of AF recurrence in this population.

Methods

A real-world cohort of AF patients who had transthoracic echocardiograms was analyzed. Data on LA size, LVEF, and MR were collected retrospectiv
