Short- and long-term associations of atrial fibrillation catheter ablation with left atrial structure and function: A cardiac magnetic resonance study.
Habibi M, Lima JAC, Gucuk Ipek E, Spragg D, Ashikaga H, Marine JE, Berger RD, Calkins H, Nazarian S. Habibi M, et al. Among authors: ashikaga h. J Cardiovasc Electrophysiol. 2021 Feb;32(2):316-324. doi: 10.1111/jce.14842. Epub 2020 Dec 29. J Cardiovasc Electrophysiol. 2021. PMID: 33350536 Free PMC article.
BACKGROUND: The effects of atrial fibrillation (AF) catheter ablation on the left atrium (LA) are poorly understood. OBJECTIVES: To examine short- and long-term associations of AF catheter ablation with LA function using cardiac magnetic resonance (CMR). ...CONCLUSIONS: LA …
