Key result
Left atrial diameters and volumes showed significant reduction after successful cardioversion, though patients undergoing DC shock had a slower recovery of atrial function and volume reduction.
Why the study?
The study aimed to evaluate left atrial functional and volumetric changes during atrial fibrillation and after cardioversion to sinus rhythm in paroxysmal atrial fibrillation to detect recovery of effective mechanical atrial function.
Does cardioversion to sinus rhythm improve left atrial volume and mechanical function in patients with paroxysmal atrial fibrillation?
Observational (n=75)
No
Does cardioversion to sinus rhythm improve left atrial volume and mechanical function in patients with paroxysmal atrial fibrillation?
Successful cardioversion of paroxysmal atrial fibrillation leads to significant reduction in left atrial volumes and recovery of mechanical function, though recovery is slower following DC shock compared to pharmacological cardioversion.
No takes yet. Share an insight, caveat, or question.
May support reverse atrial remodeling post-cardioversion; leaves open differential recovery with DC shock in observational data.
Kayed et al. (2019) conducted an observational in Paroxysmal atrial fibrillation (n=75). Cardioversion (pharmacological or DC shock) vs. Normal sinus rhythm (healthy controls) was evaluated on Left atrium functional and volume changes, and recovery of effective mechanical atrial function (EMAF). Left atrial diameters and volumes showed significant reduction after successful cardioversion, though patients undergoing DC shock had a slower recovery of atrial function and volume reduction.
