Sinus-rhythm vector-flow mapping (COHERENT module) may enable phenotype-guided ablation.</div></div><div><h3>Objective</h3><div>This study aimed to classify sinus-rhythm conduction phenotypes using COHERENT mapping and assess associations with atrial remodeling, recurrence, and thromboembolic risk.</div></div><div><h3>Methods</h3><div>We prospectively enrolled 80 consecutive patients (mean age 65.1 ± 12.5 years; 32.5% persistent atrial fibrillation [AF]) undergoing initial AF ablation with high-density sinus-rhythm mapping. 5 phenotypes were defined: normal flow, conduction delay, congested flow, disrupted flow, and Bachmann’s bundle split (BBS). Patients were grouped into 8 mutually exclusive, collectively exhaustive phenotype-burden categories (normal, 4 single-phenotype groups, double, triple, quadruple). Outcomes were assessed by unadjusted logistic regression with normal as the reference; all 80 patients completed 24-month follow-up.</div></div><div><h3>Results</h3><div>Phenotype-burden categories showed gradients in structural and AF-related markers. Each 10 mL/m² left atrial volume index increase was associated with higher odds of double (odds ratio [OR] 2.16), triple (3.02), and quadruple (3.46). 12 of 80 patients (15%) had 24-month recurrence; double showed the only nominally significant association (5 of 15 [33%]; OR 24.62; 95% confidence interval 1.16–521.53).

Phenotype burden defined a graded atrial cardiomyopathy continuum, with double showing the highest 24-month recurrence.
