چکیده
Cardioneuroablation (CNA) of ganglionated plexi (GP) is increasingly recognized for its potential to improve atrial fibrillation (AF) ablation outcomes. Computed tomography (CT)-identified epicardial adipose tissue (EAT) represents a promising approach localizing GP. However, the clinical efficacy CT-guided CNA and utility in combination with standard AF unclear. To characterize physiologic outcomes performed at time ablation. The cohort included patients who underwent CT identify EAT corresponding GP anatomic regions, which was merged electroanatomic right left maps procedure. targeting regions addition Vagal-induced defined as presence recurrent vagal triggers by history or progressive bradycardia preceding on continuous electrocardiographic monitoring. control group consisted without CNA. were assessed after 3-month post-procedure blanking period. Mean heart rate variability determined via insertable subcutaneous rhythm monitors.

During follow-up, mean did not differ between cohorts, but significantly lower (Figure 1A 1B). Over median follow-up period 430 days (IQR 199-845), flutter recurred same compared 34%, p=0.8). Patients vagal-induced (n=8, 42%) had trend toward recurrence than (13% p=0.2) 45%, results reduced affecting rate. overall different may specifically benefit AF.

video). Subsequently, the 4 PVs were electrically disconnected by circumferential radiofrequency application at the ostia (pink circles). There were no complications, the patient has had no recurrent AF, and her functional class improved (class I) during follow-up. More precise anatomic information about the LA and PVs obtained with new imaging techniques has contributed greatly to the advances...
متن کاملComputed Tomography Imaging in Atrial Fibrillation Ablation.
Atrial fibrillation (AF) is the most common supraventricular arrhythmia in adults and catheter ablation has increasingly become the therapy of choice for symptomatic, recurrent, drug refractory AF. The purpose of this review is to evaluate the utility of computed tomography (CT) imaging in guiding radiofrequency catheter ablation (RFCA), as well as highlight the additional radiographic and func...

BACKGROUND Heart failure and atrial fibrillation (AF) often coexist in a deleterious cycle. OBJECTIVE To evaluate the clinical and echocardiographic outcomes of patients with ventricular systolic dysfunction and AF treated with radiofrequency (RF) ablation. METHODS Patients with ventricular systolic dysfunction [ejection fraction (EF) <50%] and AF refractory to drug therapy underwent stepwi...
متن کاملTrigger Versus Substrate Ablation for Atrial Fibrillation.
Elimination of triggers has become the hallmark of catheter ablation of atrial fibrillation (AF). In particular, much attention has been paid to the elimination of triggering impulses from the pulmonary veins via pulmonary vein ablation procedures. While this approach has a proven track record for paroxysmal AF, the efficacy in non-paroxysmal AF has been less convincing. Thus, attention has bee...
