Iatrogenic Left Atrial Tachycardias
epending on initial ablative approach, the incidence of left trial tachycardia (LAT) or flutter after atrial fibrillation AF) ablation has varied about 10-fold. Using segmental, stial pulmonary vein (PV) and/or antral isolation, about 3% f patients require repeat ablation for LAT (1,2). Conersely, using widely encircling PV lines plus mitral and roof ines, LAT incidence is often 20% to 30% (3,4...
متن کاملAtrial Tachycardias Following Atrial Fibrillation Ablation
One of the most important proarrhythmic complications after left atrial (LA) ablation is regular atrial tachycardia (AT) or flutter. Those tachycardias that occur after atrial fibrillation (AF) ablation can cause even more severe symptoms than those from the original arrhythmia prior to the index ablation procedure since they are often incessant and associated with rapid ventricular response. D...
متن کاملOrganized Atrial Tachycardias after Atrial Fibrillation Ablation
The efficacy of catheter-based ablation techniques to treat atrial fibrillation is limited not only by recurrences of this arrhythmia but also, and not less importantly, by new-onset organized atrial tachycardias. The incidence of such tachycardias depends on the type and duration of the baseline atrial fibrillation and specially on the ablation technique which was used during the index procedu...
متن کاملLeft Ventricular Outflow Tract Tachycardias
Left ventricular outflow tract tachycardia (LVOT-VT) is an uncommon type of idiopathic left ventricular tachycardia (ILVT) thought to be due to cyclic adenosine mono phosphate (cAMP) mediated triggered activity. The arrhythmia can be terminated pharmacologically with calcium channel blockers or beta-blockers [1]. LVOT-VT can arise above or below the coronary cusps and the former variety can als...
متن کاملIatrogenic Atrial Septal Defect.
The number of left atrial transcatheter procedures performed via a transseptal (TS) approach has grown exponentially over the last 2 decades. Persistent iatrogenic atrial septal defects (iASD) after structural TS interventions are not uncommon especially when larger TS sheaths are used (25%–50% with 22 Fr sheaths). The optimal management strategy of postprocedural iASD is currently unknown. In ...
