Introduction Atrial fibrillation (AF)-induced cardiomyopathy (AIC) is retrospectively defined after normalisation of left ventricular ejection fraction (LVEF) in sinus rhythm. It is unclear why some patients develop AIC. Hypothesis Patients with AIC have a subtle cardiomyopathic process that precedes their AF-mediated LVEF reduction. Detailed assessment of cardiac function after successful catheter ablation will reveal this.

Endomyocardial biopsy (EMB) remains the reference method for diagnosing a range of cardiac conditions. Owing to its invasive nature, the risk of complications may be as high as 3%. Therefore, EMB tends to be performed when non-invasive methods are unable to reach a definitive diagnosis, guide clinical management or when histology is necessary. In such patients, the “last-resort” use of EMB may also incur diagnostic delay.

Technical success left bundle branch area pacing (LBBAP) is predicated upon deep septal penetration to capture left ventricular (LV) conduction system. Potential barriers include non-complaint interventricular septum (IVS) either due to fibrosis/scar, hypertrophy, or abnormal geometry in structurally abnormal/dilated hearts. Lead entanglement also hinders septal penetration, increases procedural/fluoroscopic times, necessitates repositioning, and usage of more hardware.
