Background: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is associated with impaired health-related quality of life (HRQoL), high symptom severity, and poor cardiovascular outcomes. Both clinical and psychological factors may contribute to symptom severity and HRQoL in AF.
Methods: Using data from the observational Atrial Fibrillation Rhine-Neckar Region (ARENA) trial, we identified medical and psychosocial factors associated with AF-related symptom severity using European Heart Rhythm Association symptom classification and HRQoL using 5-level EuroQoL- 5D.
Background: Twenty-four-month outcomes have been reported for patients with degenerative lumbar disc disease who were treated with stand-alone anterior lumbar interbody arthrodesis with use of dual tapered interbody fusion cages and recombinant human bone morphogenetic protein-2. This report represents an update of the clinical and radiographic results of this treatment at six years.
Methods: Two hundred and seventy-seven patients with single-level degenerative disc disease with up to grade-I spondylolisthesis were enrolled in two prospective, multicenter, U.
Study Design: An anatomic classification system was devised on the basis of operative reports and preoperative magnetic resonance imaging or computerized tomography from 139 patients who underwent laparoscopic anterior lumbar interbody fusion involving L4-L5.
Objective: To devise a classification system for laparoscopic exposure of the L4-L5 disc space that would allow prediction of the safest approach for any given vascular configuration.
Summary Of Background Data: The laparoscopic technique has gained acceptance at L5-S1 but has been less successful at L4-L5.
