Cavotricuspid isthmus high-density mapping
Typical atrial flutter (AFL) is a common arrhythmia that is responsible for about 10% of all hospitalizations for supraventricular tachycardia in adults. The reentrant circuit through the cavotricuspid isthmus is located in the right atrium, and the left atrium is then activated passively. Cavotricuspid isthmus radiofrequency (RF) ablation is considered a first-line therapy to achieve rhythm co...

متن کاملCavotricuspid Isthmus Anatomy in Flutter Ablation of Right Anevrismal Atrium Using Non Contact Mapping
tients with stmchmlly normal hearts following noncontact mapping guided ablation of idiopathic left or right ventricular tachycardia. A signiiicant inverse correlation was found between activation times and ARIs during sinus (I= -0.68&0.23), paced (I= -0.82&0.12), and ventricular ectopic (I= -0.66&0.43) rhythms using the alternative NCM method. However, no significant relationship between activ...
متن کاملCavotricuspid isthmus mapping to assess bidirectional block during common atrial flutter radiofrequency ablation.
BACKGROUND We sought to compare published methods to an alternative approach ascertaining cavotricuspid isthmus (CTI) block during atrial flutter ablation. METHODS AND RESULTS In 39 consecutive patients who underwent an atrial flutter ablation procedure, a 24-pole mapping catheter was positioned so that 2 adjacent dipoles were bracketing the targeted CTI line of block (LOB), with proximal dip...
متن کاملSnaring of the right ventricular lead during cavotricuspid isthmus ablation
The presence of a right ventricular (RV) lead may interfere with cavotricuspid isthmus (CTI) ablation. We present a new option of lifting the RV lead from the CTI allowing a successful ablation of a CTI-dependent flutter without compromising lead integrity and functionality.
