Three‐Dimensional Mapping in Interventional Electrophysiology: Techniques and Technology

Ablação da fibrilação atrial no Brasil: resultados do registro da Sociedade Brasileira de Arritmias Cardíacas

“…The most important of these have the objective of electrical isolation of pulmonary veins in regard to the left atrium [3][4][5][6][7][8][9][10][11] , associated or not with modifications of the atrial substrate by the creation of linear lesions in the left atrium, 10,16 elimination of fragmented potentials 12 and AF nests, 13 or the ablation of parasympathetic ganglia. 14,15 Additionally, auxiliary imaging techniques such as intracardiac echocardiography and electroanatomic mapping have been progressively more incorporated with the goal of increasing the efficiency and safety of the method 8,17 . Despite the approach and technique used, when performed by experienced operators, AF ablation has proved to be a safe method with very satisfactory results [2][3][4][5][6][7][8][9][10][11][12][13][14][15] .…”

The acoustic lens design and in vivo use of a multifunctional catheter combining intracardiac ultrasound imaging and electrophysiology sensing

“…The electrical field gradients can be sensed by either a single electrode on a single intracardiac catheter, or by as many as 64 electrodes from many different catheters. The system can determine the location of any single electrode to a spatial accuracy in the range of approximately ±1 mm, with a temporal sampling rate as high as 1200 per second [36], [37]. The key enabling feature of this technology is its adaptability; the only particular requirement for our ICE imaging catheter is the feature of EP electrodes on the catheter tip with an internal wire path to a proximal end connector compatible with the electroanatomical system inputs.…”

Use of a Novel Endoscopic Catheter for Direct Visualization and Ablation in an Ovine Model of Chronic Myocardial Infarction

“…[12][13][14][15] Intracardiac ultrasound provided the first realtime feedback of anatomy during ablation; however, the anatomic rendering was limited by the resolution and field of view of ultrasound. 16 -19 Now, direct visualization of the endocardial surface is feasible during mapping and ablation.…”
