A 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 کاملA deadly mix - rheumatic mitral stenosis, preexcited atrial fibrillation, left atrial appendage thrombus and left atrial appendage accessory pathway
A 38-year-old female with rheumatic mitral stenosis on medical management presented with palpitations and presyncope since 10 days. Electrocardiogram showed an irregular rhythm at a rate of 160 bpm with preexcitation suggestive of atrial fibrillation with a left free wall accessory pathway (Fig. 1). Transthoracic echocardiography showed severe rheumatic mitral stenosis with a valve area of 1 cm...
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...
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 کاملLeft atrial appendage closure.
Stroke prevention is the primary goal in atrial fibrillation (AF) given its clinical and socioeconomic impact. With AF, the prevalence of thromboembolic stroke continues to rise and there is an urgent need to develop better strategies of stroke prevention. Warfarin, although effective when used appropriately, is burdened by underutilization, narrow therapeutic windows, and life-threatening blee...
