A Novel Computational Platform to Analyze Left Atrial Voltage Acquired from Electroanatomic Mapping
Atrial cardiomyopathy represents structural and electrophysiologic abnormalities associated with atrial fibrillation (AF). Fibrosis, visualized with late gadolinium enhancement on cardiac magnetic resonance imaging (MRI), is associated with low voltage on electroanatomic mapping1, and ablation outcomes 2. Voltage data is readily acquired in an ablation procedure but comparing voltage between subjects is complicated by variation in atrial size and orientation. A computational analysis platform is needed that can automatically align and scale atria of disparate sizes and orientation to permit comparisons in pre-specified reg...

Defining the blanking period, using continuous ECG monitoring, after cryoballoon pulmonary vein isolation
Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation. A blanking period (BP) of 3 months is used in clinical trials and practice. However, the optimal BP duration after PVI remains undefined. (Source: Heart Rhythm)

Pulsed field ablation for atrial fibrillation in real-life settings: Efficacy, safety, and lesion durability in patients with recurrences
Initial findings from feasibility studies on pulsed field ablation (PFA) in the treatment of atrial fibrillation (AF) indicated high rates of efficacy and pulmonary vein isolation (PVI) durability on systematic remapping. Nonetheless, there remains a shortage of data regarding effectiveness, lesion durability, and safety of the procedure beyond the scope of feasibility studies. This analysis was conducted to assess the efficacy, safety, and lesion durability associated with PFA for AF in real-life settings. (Source: Heart Rhythm)

Electrocardiographic features that militate against early hospital discharge after transcatheter aortic valve replacement
An 84-year-old woman was referred for transcatheter aortic valve replacement (TAVR) after severe symptomatic aortic stenosis (valve area, 0.9 cm2; peak and mean transaortic pressure gradients of 63 mm Hg and 32 mm Hg, respectively). She had a medical history of renal cell carcinoma after nephrectomy with a creatinine level of 1.7 mg/L. Echocardiography showed preserved left ventricular function and mild to moderate aortic and mitral regurgitation. Normal coronary arteries were found on coronary angiography before TAVR.

Caudal Tilt Ultrasound: Are Things Looking Up for Axillary Vein Access?
The choice of vascular access for transvenous lead implantation must balance ease of vascular access against radiation exposure and risk of procedure-related complications. Although subclavian vein puncture has a well-defined anatomic landmark and enables access to a large caliber vein, it carries risks of pneumothorax, inadvertent arterial puncture, and lead dysfunction due to subclavian crush syndrome. In contrast, cephalic vein cutdown avoids pneumothorax and reduces fluoroscopy through direct visualization of the vein, but is limited by occasional absence of the vein, difficulty passing multiple leads, increased proced...

Predictive value of the PRAETORIAN score for defibrillation test success in patients with subcutaneous ICD: A subanalysis of the PRAETORIAN-DFT trial
The PRAETORIAN score estimates the risk of failure of subcutaneous implantable cardioverter-defibrillator (S-ICD) therapy by using generator and lead positioning on bidirectional chest radiographs. The PRAETORIAN-DFT trial investigates whether PRAETORIAN score calculation is noninferior to defibrillation testing (DFT) with regard to first shock efficacy in spontaneous events.
