Aims Complications from catheter ablation for atrial fibrillation (AF) are well described. Changing aspects of AF ablation including patient populations referred, institutional experience, and emerging catheter and pharmacological options may impact complication rates. We assessed procedural complication trends in AF ablation patients from 2003–2015 to(More)
Implantation of cardiac resynchronization therapy (CRT) devices is technically challenging and can be limited by lead dislodgement. The Attain Starfix active fixation coronary sinus (CS) lead (model 4195, Medtronic, Minneapolis, MN, USA) was introduced to reduce the rate of lead dislodgement, but the active fixation mechanism presents additional(More)
OBJECTIVES The aims of this study were to: 1) use a novel method of late gadolinium enhancement (LGE) quantification that uses normalized intensity measures to confirm the association between LGE extent and atrial fibrillation (AF) recurrence following ablation; and 2) examine the presence of interaction and effect modification between LGE and AF(More)
INTRODUCTION Phrenic nerve injury (PNI) is a well-known, although uncommon, complication of pulmonary vein isolation (PVI) using radiofrequency energy. Currently, there is no consensus about how to avoid or minimize this injury. The purpose of this study was to determine how often the phrenic nerve, as identified using a high-output pacing, lies along the(More)
BACKGROUND Symptomatic left atrial (LA) flutter (LAFL) is common after atrial fibrillation (AF) ablation. OBJECTIVE The purpose of this study was to examine the association of baseline LA function with incident LAFL after AF ablation. METHODS The source cohort included 216 patients with cardiac magnetic resonance (CMR) before initial AF ablation between(More)
