Left Atrial Appendage Tilt-Up-and-Turn-Left Maneuver: A Novel Three-Dimensional Transesophageal Echocardiography Imaging Maneuver to Characterize the Left Atrial Appendage and to Improve Transcatheter Closure Guidance
Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide, with both incidence and prevalence on the rise. It is estimated that by 2050, up to 16 million people in the United States alone will experience AF.1 Prevention of systemic thromboembolism and stroke is the cornerstone of long-term management of AF. Although prevention of thromboembolism is often achieved through the use of oral anticoagulants, these agents may be contraindicated in certain patients because of bleeding risk.
