Intracardiac Echocardiography during Catheter-Based Ablation of Atrial Fibrillation
Figure 1
Visualisation of the LA and its adjacent structures with 2D ICE. (a) Interatrial septum (IAS), left superior pulmonary vein (LSPV), and left inferior pulmonary vein (LIPV). (b) The Brockenbrough-curved needle (BCN) is advanced from the right atrium to the IAS for transseptal puncture guided by ICE. (c) After successful transseptal puncture tenting of the IAS and the tip of the BCN in the LA are seen. (d) Example of abnormal anatomy of the IAS. An aneurysmatic IAS can hamper transseptal puncture. Progress of transseptal puncture can easily be visualised by 2D ICE.
