Comparative StudyComparing Measurements of CT Angiography, TEE, and Fluoroscopy of the Left Atrial Appendage for Percutaneous Closure.
Left atrial appendage (LAA) closure requires accurate preprocedural measurements, and trans-esophageal echocardiography (TEE), cardiac computed tomography angiography (CCTA) and fluoroscopy can be utilized. However, correlations between these measurements remain inadequately assessed. ⋯ All 3 imaging modalities correlated with ACP landing zone and WATCHMAN ostium measurements, with CCTA providing the largest measurements, followed by TEE and fluoroscopy.

Observational StudyWireless Ultrasound-Guided Axillary Vein Cannulation for the Implantation of Cardiovascular Implantable Electric Devices.
Ultrasound guidance for vascular cannulation seems safer and more effective than an anatomical landmark approach, though it has not gained widespread support partly due to workflow interference of wired probes. A wireless ultrasound transducer (WUST) may overcome this issue. We report the effectiveness, time consumption, and safety of the first-in-human experience in axillary vein cannulation guided with a novel WUST for the implantation of cardiovascular implantable electric devices (CIEDs). ⋯ Ultrasound-guided axillary vein cannulation using a wireless transducer for the implantation of CIEDs is a feasible, fast, and safe method.

Efficacy of Cryoballoon Pulmonary Vein Isolation in Patients With Persistent Atrial Fibrillation.
Cryoballoon PVI has emerged as an alternative to radiofrequency PVI for the treatment of paroxysmal AF. The optimal strategy for patients with persistent AF is unclear as data are limited. ⋯ Cryoballoon PVI appears to be an effective initial strategy in treating persistent AF, with an AF recurrence-free rate of 59% at 1 year.
