Patients with atrial fibrillation (AF) may benefit from undergoing concomitant interventions of left catheter ablation and device occlusion the appendage (LAA) as a two-pronged strategy for rhythm control stroke prevention. We report on outcome combined procedures in single center case series over 5-year timeframe.Ninety-eight patients non-valvular AF mean CHA2DS2-VASc score 2.6±1.0 underwent either first time, or redo pulmonary vein isolation (PVI) procedures, followed by successful implant...
Left atrial appendage device occlusion is an increasingly accepted therapy for stroke prevention in fibrillation. The feasibility and safety of left catheter ablation procedures the presence a implant unclear. We report on 10 cases successful fibrillation patients with implanted Watchman® device.Consecutive existing symptomatic antiarrhythmic-drug refractory or tachycardias requiring were included. Open irrigated tip circular mapping catheters positioned atrium via double transseptal access....
Background Recent investigations have identified a faster time to publication for imaging studies with higher diagnostic test accuracy (DTA), but it is unknown whether such are more likely be published. A probability of full-text DTA could negative consequences on clinical decision making and patient care. Purpose To evaluate the proportion presented as conference abstracts that reach identify there an association between in peer-reviewed journals within 5 years after abstract submission....
OBJECTIVE. The purpose of this study was to assess the use an electronic consultation platform connect primary care providers and radiologists provide opportunities for valuable regarding diagnostic imaging in patients, as well identify targeted education surrounding high-yield radiology topics. MATERIALS AND METHODS. A retrospective review performed consultations conducted using from September 2012 January 2017. Consultations were classified by subspecialty (neuroradiology, thoracic,...
Background Patients with atrial fibrillation (AF) may be interested in undergoing concomitant interventions of left catheter ablation and device occlusion the appendage (LAA). We report on feasibility outcome combined procedures a single centre case series. Methods Twenty-six patients underwent either first time or redo pulmonary vein isolation (PVI) followed by successful implant Watchman® device. Results All were uncomplicated mean 233 ± 38 minutes. Maximal LAA orifice dimension was...
Background Breakthrough hypersensitivity reactions (HRs) to gadolinium-based contrast agent (GBCA) occur in 40% of patients despite corticosteroid premedication. Other strategies reduce HRs are not well studied. Objective The aim this study was prospectively evaluate HR rate GBCA among with history GBCA, empirically given an alternative prior repeat administration. Materials and Methods From September 2019 2020, received 13-hour oral diphenhydramine premedication prescription switching...
Objective The purpose of this study was to assess the rate and severity breakthrough allergic-like reactions gadobutrol. Materials Methods Under a waiver from our institutional review board, we performed key word search PACS (Picture Archiving Communication System) database identify all reactions, which occurred in setting gadobutrol administration between December 2009 August 2018, encompassing approximately 25,000 injections. Patients with an index reaction who underwent subsequent...
Background Renal angiomyolipoma (AML) are benign masses that require detection of macroscopic fat for accurate diagnosis. Purpose To evaluate material-specific images derived from dual-energy computed tomography (DECT) to diagnose renal AML. Material and Methods This retrospective case-control study evaluated 25 AML 44 solid (41 cell carcinomas, three other tumors) imaged with rapid-kVp-switch DECT (120 kVp non-contrast-enhanced [NECT], 70-keV corticomedullary [CM], 120-kVp nephrographic...
The Contact (St Jude Medical) System uses a novel impedance- based measure of Electrical Coupling Index (ECI) to assess the quality catheter tip endocardium contact. We sought establish average ECI measurements and behaviour during pulmonary vein (PV) isolation procedures. Forty-five patients undergoing PV for atrial fibrillation (AF) were studied.'Non-contact' upper range 'in-contact' positioning was performed system calibration. recorded pre-ablation at 14 standardized locations around...
