Prospective validation of phased array intracardiac echocardiography for the assessment of atrial mechanical function during catheter ablation of atrial fibrillation

LAAEV has been clinically used to evaluate atrial mechanical stunning and the recovery of atrial function after cardioversion of atrial flutter and fibrillation. 4 It is a strong parameter representative of atrial mechanical function and has been shown together with LASEC to be an excellent predicto...

Description
Summary:LAAEV has been clinically used to evaluate atrial mechanical stunning and the recovery of atrial function after cardioversion of atrial flutter and fibrillation. 4 It is a strong parameter representative of atrial mechanical function and has been shown together with LASEC to be an excellent predictor of thrombus formation and stroke in patients with atrial arrhythmias. 1 Previous studies of ICE have focused on visualisation of anatomical details to guide interventional approaches. The study evaluated patients during regular tachycardia or sinus rhythm and observed a strong correlation for LAAEV, LAA fractional area change, and PV and mitral valve Doppler flow velocities.
