Key result
Pre-PVAI CMR detects LV LGE in ~37% of AF patients, predicted by age and HF.
Why the study?
What is the prevalence, pattern, and clinical predictors of left ventricular late gadolinium enhancement in patients undergoing CMR before pulmonary vein antral isolation for atrial fibrillation?

What is the prevalence, pattern, and clinical predictors of left ventricular late gadolinium enhancement in patients undergoing CMR before pulmonary vein antral isolation for atrial fibrillation?
There is a high prevalence (37%) of unexpected, mostly nonischemic left ventricular scar in patients undergoing CMR before PVAI for atrial fibrillation, suggesting CMR may be valuable for pre-procedural imaging integration.

LV LGE on pre-PVAI CMR may signal higher-risk AF subsets; hypothesis-generating for prognostic or therapeutic implications.
Nance et al. (2015) conducted a cross-sectional in Atrial fibrillation (n=62). Left ventricular late gadolinium enhancement (LV LGE) vs. No LV LGE was evaluated on Prevalence of left ventricular late gadolinium enhancement (LV LGE). In patients with atrial fibrillation undergoing CMR before PVAI, 37% demonstrated left ventricular late gadolinium enhancement, with age (P=0.04) and heart failure history (P=0.03) as predictors.
