Ablation Via the Left Atrial Appendage
Method Fourteen consecutive patients with long term and short term persistent atrial fibrillation were the basis of this report. On full cardiopulmonary bypass, radiofrequency clamps were applied to the epicardial left atrial tissue surrounding the right and left pulmonary veins, separately. The left atrial appendage was amputated on the arrested heart. Via that defect, an epicardial to endocar...
متن کاملA Semi-Automated Algorithm for Segmentation of the Left Atrial Appendage Landing Zone: Application in Left Atrial Appendage Occlusion Procedures
Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
متن کاملPercutaneous interventions in elderly patients with atrial fibrillation: left atrial ablation and left atrial appendage occlusion
Heart rhythm disturbances become of special importance when patients reach a senior age. Atrial fibrillation (AF) is the most prevalent arrhythmia among the old age groups, and its impact on morbidity and mortality becomes of paramount significance. In this population, AF is responsible for significant amount of thromboembolic cerebrovascular events, especially for disabling and fatal strokes. ...
متن کاملLeft Atrial Appendage Remodeling After Lariat Left Atrial Appendage Ligation.
BACKGROUND Left atrial appendage (LAA) ligation with the Lariat device is being used for stroke prevention in atrial fibrillation. Residual leaks into the LAA are commonly reported after the procedure. Little is known about the anatomic LAA remodeling after Lariat ligation. METHODS AND RESULTS In an exploratory study, we evaluated LAA 3-dimensional geometry via computed tomographic scan in 31...
متن کاملRadiofrequency ablation of left atrial appendage accessory pathway.
A 47-year-old man was referred to our hospital due to recurrent episodes of narrow QRS complex tachycardia. Baseline electrocardiogram showed ventricular pre-excitation in favour of left-sided accessory pathway (AP), so we decided to perform radiofrequency (RF) mapping and ablation of AP. During the ventricular pacing and orthodromic atrioventricular reciprocating tachycardia, the earliest atri...
