Catheter ablation significantly improved bi-atrial function and biventricular systolic function within 48 hours, despite left ventricular diastolic function being stunned.
Does catheter ablation alter very early (≤ 48 h) cardiac hemodynamics and echocardiographic function in patients with atrial fibrillation?
Catheter ablation for atrial fibrillation induces an immediate elevation in biatrial pressures and stunning of left ventricular diastolic function, despite early improvements in biventricular systolic function.

Abstract All chambers’ systolic functions were improved with long-term follow-up after catheter ablation (CA). However, changes on cardiac function on very early phase (within 48 h) has not been thoroughly investigated. This study aimed to evaluate the acute effects of CA on cardiac function and morphology immediately post-procedural (≤ 48 h). We prospectively enrolled 117 consecutive patients. Hemodynamic parameters including biatrial pressure and echocardiographic data were acquired pre- and post-ablation. (i) All bi-atrial pressures significantly elevated post-ablation (p 0.05). (iv) No statistically significant differences in pre- versus post-procedural pressure changed between patients with persistent AF and those with paroxysmal AF in biatrial pressure elevation (p > 0.05). (v) Echocardiographic parameters including LA reservoir strain, RA reservoir strain, peak A of mitral valve, peak E of tricuspid valve and inferior vena cava diameters increased more in persistent AF groups (p < 0.05). This prospective study suggested all chambers’ systolic functions improved in early period post-ablation with left ventricular diastolic function stunning. Mechanical improvements preceding structural remodeling in AF patients early after ablation.
