Simultaneous isolation of the four pulmonary veins by single-sided antral ablation
نویسندگان
چکیده
Figure 1 Intracardiac tracings from the left superior pulmonary vein (LSPV), left inferior pulmonary vein (LIPV), right superior pulmonary vein (RSPV), right inferior pulmonary vein (RIPV) and coronary sinus (CS): before ablation (left) and after left antral circumferential ablation (center). Transthoracic echocardiogram showing severe right atrial and right ventricular dilatation with apical displacement of the tricuspid valve leaflets (top right). Geometry of both atria generated by Ensite NavX; the brown dots indicate the ablation lesions around the left pulmonary veins antrum (bottom right).

Robot-assisted epicardial ablation of the pulmonary veins: is a completed isolation necessary?
AIMS To study the feasibility and electrophysiological efficacy of minimally invasive beating heart ablation of the pulmonary veins (PVs) via a robot-assisted single-sided approach. BACKGROUND PV isolation by minimally invasive epicardial ablation may offer a new treatment for patients with lone atrial fibrillation (AF). However, complete PV isolation has been shown to be difficult to obtain....
متن کاملSingle-ring posterior left atrial (box) isolation results in a different mode of recurrence compared with wide antral pulmonary vein isolation on long-term follow-up: longer atrial fibrillation-free survival time but similar survival time free of any atrial arrhythmia.
BACKGROUND Electric isolation of the pulmonary veins and posterior left atrium with a single ring of radiofrequency lesions (single-ring isolation [SRI]) may result in fewer atrial fibrillation (AF) recurrences than wide antral pulmonary vein isolation (wide antral isolation [WAI]) by abolishing extravenous AF triggers. The effect of mitral isthmus line (MIL) ablation on outcomes after SRI has ...
متن کاملSuccessful Multi-chamber Catheter Ablation of Persistent Atrial Fibrillation in Cor Triatriatum Sinister
Cor triatriatum sinister is a rare congenital cardiac anomaly with an incidence of between 0.1 and 0.4% [1,2] whereby the left atrium is functionally and anatomically divided into two separate chambers by a thin membrane. Although there are a limited number of reports of successful ablation of left atrial focal tachycardia and simple pulmonary vein isolation in individuals with cor triatriatum ...
متن کاملA minimal or maximal ablation strategy to achieve pulmonary vein isolation for paroxysmal atrial fibrillation: a prospective multi-centre randomized controlled trial (the Minimax study).
AIMS Pulmonary vein isolation (PVI) is the cornerstone of catheter ablation of atrial fibrillation (AF). The intervenous ridge (IVR) may be incorporated into ablation strategies to achieve PVI; however, randomized trials are lacking. We performed a randomized multi-centre international study to compare the outcomes of (i) circumferential antral PVI (CPVI) alone (minimal) vs. (ii) CPVI with IVR ...
متن کاملCurrent Hot Potatoes in Atrial Fibrillation Ablation
Atrial fibrillation (AF) ablation has evolved to the treatment of choice for patients with drug-resistant and symptomatic AF. Pulmonary vein isolation at the ostial or antral level usually is sufficient for treatment of true paroxysmal AF. For persistent AF ablation, drivers and perpetuators outside of the pulmonary veins are responsible for AF maintenance and have to be targeted to achieve sat...
