Post Procedural Peak Left Atrial Contraction Strain Predicts Recurrence of Arrhythmia after Catheter Ablation of Atrial...
Left atrial function deteriorates immediately following AF ablation and partially recovers in 3 months but remains ... Peak left atrial contraction strain (PACS) and left atrial emptying fraction (LAEF) were evaluated during sinus rhythm and ... function can be impaired by the atrial fibrillation (AF) ablation and might be associated with the risk of recurrence. We ... The primary endpoint was atrial tachyarrhythmia recurrence after ablation. A total of 144 patients were enrolled (mean age 61 ...
Flow propagation velocity is not a simple index of diastolic function in early filling. A comparative study of early diastolic...
The present study shows strain rate propagation to be a measure of filling time, but flow propagation to be a function of both ... 12 normal subjects and 13 patients with treated hypertension and normal systolic function were studied. Patients and controls ... Thus flow propagation is not a simple index of diastolic function in delayed relaxation. ... The picture shows early filling (E) and atrial systole (A). The two phases of early filling phase I or column propagation and ...
