Very early cardiac hemodynamic changes after atrial fibrillation ablation.

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 < 0.002). (ii) Bi-atrial function including ejection fraction, reservoir strain and conduit strain improved immediately after ablation (p < 0.01). Persistent atrial fibrillation (AF) improved more than paroxysmal AF. (iii) Bive
