Typical atrial flutter (AFL), defined as cavotricuspid isthmus (CTI)-dependent macro-re-entrant atrial tachycardia, often causes debilitating symptoms, and is associated with increased incidence of atrial fibrillation, stroke, heart failure, and death. Typical AFL occurs in patients with atrial remodeling and shares risk factors with atrial fibrillation. It is also common in patients with a history of prior heart surgery or catheter ablation.

Background: Minimally invasive cardiac surgery for mitral regurgitation is challenging in patients with narrow chests due to limited thoracic space. The butterfly technique can prevent systolic anterior motion in patients with degenerative mitral regurgitation and redundant posterior leaflets, but it is difficult to perform via minimally invasive cardiac surgery. Few reports have described mitral valve repair using the butterfly technique or in a narrow chest.

Convincing evidence for the efficacy of ablation as first-line therapy in paroxysmal AF (PAF) and its clear superiority to medical therapy for rhythm control in both PAF and persistent AF (PsAF) has generated considerable interest in the optimal timing of ablation. Based on this data, there is a widespread view that the principle of 'the earlier the better' should be generally applied. However, the natural history of AF is highly variable and non-linear, and for this reason, it is difficult to be emphatic that all patients are best served by ablation early after their initial AF episodes.

Introduction: Intracardiac echocardiography (ICE) is an essential imaging modality for electrophysiology procedures, allowing intraprocedural monitoring, real-time catheter manipulation guidance, and visualization of complex anatomic structures. Four-dimentional (4D) ICE is the next stage in the evolution of the technology, permitting 360° rotation of the imaging plane, simultaneous multiplanar imaging, and volumetric acquisition, similar to transesophageal echocardiography (TEE). In this study, we report our experience with a novel 4D ICE catheter (NuVision, Biosense Webster) in structural electrophysiology procedures and difficult ventricular ablations in a swine preclinical model.

Background: Cryoballoon ablation has been widely performed in patients with paroxysmal atrial fibrillation (AF). In some challenging pulmonary veins (PVs), the procedure requires additional touch-up applications against the residual conduction gaps. It implies that there could exist difficult sites to cover with standard cryoballoon applications (CBAs), resulting in resistant conduction gaps (RCGs).
