Is Echocardiography Useful to Predict Successful Cardioversion of Atrial Fibrillation and Long-Term Maintenance of Sinus Rhythm?
Atrial fibrillation (AF) is the most frequently sustained arrhythmia; it occurs in 2%–4% of people aged over 60 years and in almost 9% of octogenarians . People affected by AF exhibit a higher risk of heart failure and, above all, of embolic events . It is not definitively established whether sinus rhythm restoration and maintenance warrant a better prognosis than chronic persistence of the arrhythmia combined with optimal control of the heart rate and anticoagulation therapy to prevent thromboembolism , but nevertheless in common clinical practice cardioversion is proposed in order to improve cardiac function and survival .
