The left atrioventricular coupling index (LACI), which evaluates the synergistic function of the left atrium and ventricle and overall cardiac performance, is closely associated with cardiovascular outcomes. However, its relationship with post\u2010ablation recurrence remains unclear. This study aimed to quantify left atrial coupling index (LACI) using real\u2010time three\u2010dimensional echocardiography (RT\u20103DE) to predict late recurrence and guide personalized therapeutic strategies, thereby reducing recurrence rates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Patients with paroxysmal AF undergoing initial radiofrequency ablation at Yichang Central People's Hospital (October 2019\u2013December 2023) were categorized into recurrence, non\u2010recurrence, and healthy control groups.

Univariate analysis indicated that left atrial diameter (LAD), left atrial end\u2010diastolic volume (LAEDV), LACI, left atrial ejection fraction (LAEF), mitral E velocity, and left atrial reservoir strain (LAGLS) were associated with recurrence.
