Clinical TrialWireless Ultrasound Guidance for Femoral Venous Cannulation in Electrophysiology: Impact on Safety, Efficacy, and Procedural Delay.
Ultrasound (US) guidance increases safety and efficacy in vascular cannulation and is considered the standard of care. However, barriers including workflow interference and the need to be assisted by a second operator limit its adoption in clinical routine. The use of wireless US (WUS) may overcome these barriers. The aim of this study was to assess the impact of a novel WUS probe during its initial implantation in an electrophysiology (EP) laboratory. ⋯ WUS guidance resulted in faster, safer, and more effective femoral venous cannulation than the anatomical landmark approach without adding significant workflow interference. The application of wireless technology in this setting contributed to overcoming some of the barriers preventing a more widespread clinical use of US guidance.

Clinical TrialPulmonary Vein Isolation Using the First-Generation Cryoballoon Technique in Chinese Patients.
Cryoballoon ablation is an alternative for the treatment of atrial fibrillation (AF). We assess the relationship among pulmonary vein (PV) electrophysiology, balloon temperature, and persistent PV isolation (PVI), and report procedural properties, safety, and efficacy of this technique in a Chinese center for the first time. ⋯ Real-time PV potentials can be recorded in most PVs. The time to isolation is predictive of the persistency of PVI. The nadir balloon temperature, not the balloon temperature at isolation, is significantly lower in PVs without reconduction.
