Role of real time three-dimensional transesophageal echocardiography in guidance of interventional procedures in cardiology.

摘要

Real-time three-dimensional transesophageal echo-cardiography (RT-3D TEE) employs a dedicated novel matrix-array technology and allows live three-dimensional (3D) presentation of cardiac structures, circumventing most of the time-consuming acquisition and offline data processing associated with reconstructive 3D methods. It is particularly useful in guiding non-coronary cardiac interventions, defining location, morphology and possible pathology of cardiac structure of interest, its anatomical relation to neighbouring landmarks while providing improved spatial resolution and, in addition, allowing online monitoring of the procedure. These advantages over two-dimensional (2D) transesophageal echocardiography (TEE), intracar-diac echocardiography and fluoroscopy may enhance decision-making, reduce fluoroscopy time and increase procedural safety and efficacy in short and long-term follow-up.
