Real-world evaluation of intracardiac echocardiography guided radio-frequency catheter ablation for atrial fibrillation: a retrospective cohort study.

Intracardiac echocardiography (ICE) has been used to guide radio-frequency catheter ablation (RFCA) for better catheter navigation and less radiation exposure in treating atrial fibrillation (AF). This retrospective cohort study enrolled 227 AF patients undergoing ICE- or traditional fluoroscopy (TF)-guided RFCA for AF in a tertiary hospital. ICE was used more often in patients with atrial tachycardia [odds ratio (OR) 3.

Oropharynx pain, discomfort, and economic impact of transesophageal echocardiography for planned radio-frequency catheter ablation in patients with atrial fibrillation: A cross-sectional survey study.

Background: To survey the unmet medical needs associated with atrium thrombus screening in Chinese patients with atrial fibrillation (AF) who underwent transesophageal echocardiography (TEE) for planned radio-frequency catheter ablation (RFCA).

Methods: This cross-sectional survey study interviewed 300 patients who underwent their first TEE for planned RFCA. The surveyed information included patients' anxiety, oropharynx pain and discomfort, time expense, and patient satisfaction related to TEE examination.

Clinical effectiveness and efficiency of a new steerable sheath technology for radiofrequency ablation in Chinese patients with atrial fibrillation: a retrospective comparative cohort study.

Background: The clinical effectiveness and efficiency of a steerable sheath for radiofrequency catheter ablation (RFCA) in Chinese patients with atrial fibrillation (AF) needs to be compared with a fixed curve sheath to optimize RFCA procedure.

Methods: This retrospective study included adult AF patients with their first RFCA that was conducted by the same electrophysiologist using a steerable sheath (VIZIGO, Biosense Webster, Inc.) or a fixed curve sheath (NaviEase, Synaptic Medical) in a Chinese tertiary care hospital from January to November 2021.
