Abstract:
Transcatheter technology has been increasingly used for paravalvular leak closure. We report the use of "Fusion Technology" (EchoNaviagator, Phillips, Tustin, CA) that combines real-time 2 and 3 dimensional trans-esophageal echocardiography with fluoroscopy imaging to facilitate paravalvular leak closure. This could help to identify the exact site, size, depth and shape of the paravalvular leak for proper positioning of the occluder device, which may result in saving time and effort.
