Abnormal endothelial function promotes atherosclerotic vascular disease in diabetes. Experimental studies indicate that disruption of insulin signaling, through the activity protein kinase C-β (PKCβ) and nuclear factor κB, reduces nitric oxide availability. We sought to establish whether similar mechanisms operate endothelium human diabetes mellitus.We measured expression response freshly isolated cells from patients with type 2 mellitus (n=40) nondiabetic controls (n=36). Unexpectedly, we...
Background: Stereotactic body radiation therapy (SBRT) is a novel treatment for refractory ventricular tachycardia (VT). While outcomes have been described in small studies, histological findings after SBRT VT are unknown. Methods: We identified 4 explanted hearts the context of transplant that received prior as part an 11-patient compassionate use series at our institution. Clinical VTs and computed tomography–defined target volume areas were correlated to anatomic specimens. Gross...
Background Initial studies of stereotactic body radiation therapy (SBRT) for refractory ventricular tachycardia (VT) have demonstrated impressive efficacy. Follow-up analyses found mixed results and the role SBRT VT remains unclear. We performed palliative, cardiac radio ablation in patients with to medical management. Methods Arrhythmogenic regions were targeted by combining computed tomography imaging electrophysiologic mapping collaboration from a oncologist, electrophysiologist...
Patients with peripheral artery disease (PAD) have higher cardiovascular event rates than patients established coronary (CAD) and abnormal endothelial function predicts risk in PAD CAD. We investigated the hypothesis that is associated a greater degree of impairment vascular used several non-invasive tests to evaluate 1320 men women combined CAD ( n = 198), alone 179), 466), or controls aged > 45 years without 477). had lower brachial flow-mediated dilation (5.1 ± 3.9% CAD, 5.9 4.4%...
Following catheter ablation, vascular access management involves potential complications and prolonged recovery. Recently, suture-mediated closure (SMC) devices were approved for venous procedures. The objective of this study is to evaluate the safety a commercially available SMC multiple site by duplex ultrasound (DUS) in asymptomatic subjects with non-visible complications.
Abstract Background Data on the management of Micra transcatheter pacing system (TPS) at time an upgrade or during battery depletion is limited. Objective We sought to evaluate patterns patients implanted with a TPS long‐term follow‐up. Methods retrospectively identified who underwent implantation from April 2014 November 2019. extraction ( n = 11) had abandoned 12). Results 302 received period study. Mean age was 72.7 ± 15.4 years, 54.6% were men, and left ventricular ejection fraction 51.9...
Data suggests that same day discharge after implantation of trans-venous pacemakers is safe and feasible. We sought to determine whether was feasible following Medtronic MICRA leadless pacemakers.We retrospectively identified all patients undergoing placement at our institution between April 2014 August 2018 (n=167). Patients were stratified into two groups: those discharged on the as their procedure (SD, n=25), observed for least one night in hospital (HD, n=142). The primary endpoint...
Implantation of the MICRA Leadless pacemaker requires use a 27 French introducer, blunt delivery system and device fixation to myocardium via nitinol tines. While prior studies have proven its safety, it is unclear whether performing this procedure with uninterrupted anticoagulation exposes patients increased risks. We sought investigate feasibility safety continuing therapeutic during periprocedural period.We evaluated all undergoing placement at our institution between April 2014 August...
Abstract Background There are limited data on cardiac implantable electronic device implantation (CIED) in patients with persistent left superior vena cava (PLSVC). Objective To describe the outcomes of implanting CIEDs a focus resynchronization therapy (CRT) PLSVC. Methods We identified all PLSVC that underwent CIED from December 2008 until February 2019 at our institution by querying medical record (n = 34). then controls 3:1 fashion 102) matching type (CRT vs non‐CRT). Procedure success,...
Consensus statements on lead extraction give consideration to open surgical removal in the setting of large vegetations, mitigate risk massive embolism that may occur with percutaneous removal. Vacuum-assisted debulking (VD) vegetations as an adjunct provide opportunity these risks.We retrospectively identified all patients undergoing at our institution for endovascular infection from 2012 2018 and stratified them into two groups based presence adjunctive VD (n = 6) or without (no-VD, n 39)....
Purpose Robotic coronary artery bypass (rCABG) is a relatively novel and less invasive form of surgery. A yearlong direct-to-consumer advertising (DTCA) campaign was initiated to provide the community with information regarding rCABG, increase awareness recruit patients. To optimize content ensure appropriate messaging for future campaigns, this study aims analyze effectiveness compared service quality perceptions clinical outcomes, following surgery across DTCA-responder control groups....
Robotic-assisted coronary artery bypass grafting (r-CABG) requires the placement of ports bluntly through chest wall. When removed, these create bleeding sites that can be difficult to detect and treat. This study evaluated whether a topical hemostatic agent placed locally within helps reduce blood product requirements.We retrospectively analyzed outcomes for r-CABG cases where 5 mL flowable was injected all port (hemostat group, n = 62) compared with patients whose were untreated (controls,...
