Clinical Trial: Research on Post-Stroke Anticoagulation Strategies for Atrial Fibrillation Based on Left Atrial Appendage Flow Velocity Measured by Intracardiac Echocardiography (ICE)

U.S., Feb. 28 -- ClinicalTrials.gov registry received information related to the study (NCT07439731) titled 'Research on Post-Stroke Anticoagulation Strategies for Atrial Fibrillation Based on Left Atrial Appendage Flow Velocity Measured by Intracardiac Echocardiography (ICE)' on Feb. 23.

Brief Summary: 1. Study Purpose The primary aim of this research was to systematically describe and characterize a novel, thrombus-mimicking artifact observed during Intracardiac Echocardiography (ICE), termed the "Floating Lotus" sign. The study sought to define its imaging features, determine its prevalence, and identify the clinical factors that predict its occurrence. This was driven by the clinical need to prevent the misdiagnosis of this pseudo-thro...
