How to perform left atrial appendage electrical isolation using radiofrequency ablation
Although pulmonary vein (PV) isolation (PVI) has been considered an effective treatment for paroxysmal atrial fibrillation (AF), non-paroxysmal AF is a complex arrhythmia for which no ablation strategy has been demonstrated to be effective and widely accepted. As such, a success rate of ∼55% in these patients with AF (Substrate and Trigger Ablation for Reduction of Atrial Fibrillation Trial Part II [Star AF II trial]) is not acceptable in our opinion and efforts should be made to seek for alternative strategies.LAA ligation using the LARIAT suture delivery device: Tips and tricks for a successful procedure
Chronic oral anticoagulation (OAC) has traditionally been considered as the most effective prophylaxis against thromboembolic events in patients with atrial fibrillation (AF). However, as many as 20% of the patients with AF are not candidates for OAC.1,2 Reasons for ineligibility range from intracranial bleeding (the most serious complication) to increased propensity for mechanical injury (the least serious complication). The resumption of OAC in patients who have suffered a life-threatening complication due to OAC is associated with a much higher risk of such events in the future.
