In the past years, the clinicians detected the location of the catheter through angiography images and measure the size of the ASD by balloon catheter test. However, the cardiac catheterization can not display the whole view of the ASD, such as the location, size, and rim of the ASD. Therefore, we utilize the transesophageal echocardiography (TEE) to observe the ASD. However, TEE needs general anesthesia with clinical risk. Intra-cardiac echocardiography (ICE) not only allows us to observe the atrium structure in the heart, but also to evaluate the device closure of ASD for guidance during the operation. This research utilized the ICE to observe the atrium structure during cardiac catheterization procedures & interventional closure of ASD. Since the heart is a three-dimensional anatomical structure and two-dimensional ICE images often needed to reconstruct to assess the three-dimensional structure of the atrium and ASD. In this study, we develop a real-time ICE converting to three-dimensional reconstruction system. The operator of transcatheter closure of ASD can realize the three-dimensional ASD and the relevance to cardiac anatomy in 3D feature. The transcatheter of ASD will be safer and easier with this new 3D Image Reconstruction of Cardio-anatomy using Intracardiac Echocardiography.
