Atrial flutter (AFL) is one of the most common cardiac arrhythmias in humans, affecting approximately 190,000 people in the United States in 2005; its prevalence is expected to increase to 440,000 by 2050 because of the increasingly older population. 1 AFL usually coexists with atrial fibrillation (AF) and is generally initiated through a transitional phase of AF. 2 AFL most often occurs in the context of structural heart disease (e.g., valvular heart disease, ischemic heart disease Ablation of typical atrial flutter involves interruption of the right atrial macroreentrant circuit via the application of energy along the critical isthmus between the tricuspid valve and the inferior vena cava (IVC). Radiofrequency catheter ablation (RFCA) of isthmus-dependent AFL is performed with a steerable mapping/ablation catheter positioned across the CTI via a femoral vein. 3, 5 – 7, 24 – 26 Catheters with either saline-irrigated ablation electrodes (Thermocool Classic or SF, Biosense Webster, Inc, Diamond Bar, CA, or Chili, Boston Scientific, Inc., Natick, MA), or large distal ablation 2021-03-16 · Background Radiofrequency ablation of type 1 atrial flutter (AFl) has recently evolved toward an anatomically guided procedure directed to isthmuses at the lower part of the right atrium (RA). However, different types of block at these isthmuses may be observed and potentially correlated with different late outcomes. Atrial flutter most commonly occurs in a reentrant circuit around the tricuspid valve — typical atrial flutter or type I. Ablation for this rhythm is easy since it requires only venous access to Se hela listan på Se hela listan på Transvenous catheter ablation has become the therapy of choice for patients with recurring, isthmus-dependent right atrial flutter.

Transvenous catheter ablation has become the therapy of choice for patients with recurring, isthmus-dependent right atrial flutter. Achieving bidirectional conduction block in the cavotricuspid isthmus is decisive for both acute and long-term therapy success and essentially depends on the selected ablation method and the lesion size. 2017-01-09 Electrograms recorded from two distal electrode pairs (E1 and E2) positioned just anterior to the ablation line were analyzed during atrial flutter and during coronary sinus pacing, before and after ablation.

Finally, they were able to convert him from Flutter to normal sinus rhythm (NSR) by making a Mitral Isthmus ablation line. Se hela listan på Patients with Atrial Flutter and patients with Atrial Fibrillation scheduled to undergo RF ablation of the cavotricuspid isthmus (CTI).

Both male and female subjects who meet all eligibility criteria and give written informed consent will be enrolled in the study. OBJECTIVE To describe the electrocardiographic and electrophysiological findings of new atrial flutter developing in patients taking class IC antiarrhythmic drugs for recurrent atrial fibrillation, and to report the long term results of right atrial isthmus ablation in relation to the ECG pattern of spontaneous atrial flutter. Atrial fibrillation (AF) and atrial flutter (AFL) are coexisting arrhythmias.1 In AF populations, 30% have documented AFL,2 and cavotricuspid isthmus block (CTIB) is frequently performed in addition to left atrial ablation.34Currently, few studies have addressed the necessity of combined right and left atrial ablation in AF patients.2 5–9 In Usefulness of pre-procedure cavotricuspid isthmus imaging by modified transthoracic echocardiography for predicting outcome of isthmus- dependent atrial flutter ablation.
