Augmented reality (AR) guidance holds potential to improve transcatheter interventions by enabling visualization of and interaction with patient-specific 3-dimensional virtual content. Positioning cerebral embolic protection devices (CEP) during aortic valve replacement (TAVR) increases patient exposure radiation iodinated contrast, procedure time. AR may enhance procedural facilitate a safer intervention.
The purpose of this study was to characterize the anatomic relationship between inferior vena cava (IVC) and tricuspid annulus (TA) its potential impact on performance transcatheter TV interventions.Transcatheter valve (TV) interventions are emerging as a therapeutic alternative for treatment severe, symptomatic regurgitation (TR). Progression TR is associated with right heart dilatation. These changes may distort IVC-TA successful implantation devices.Fifty patients who presented...
Vascular interventions are minimally invasive surgical procedures in which a physician navigates catheter through patient's vasculature to desired destination the body. Since perception of relevant patient anatomy is limited this sort, virtual reality and augmented systems have been developed assist 3D navigation. These often require user interaction, yet both physician's hands may already be busy performing procedure. To address need, we demonstrate hands-free interaction techniques that...
Background Cardiovascular procedural treatments were deferred at scale during the COVID-19 pandemic, with unclear impact on patients presenting non-ST-segment-elevation myocardial infarction (NSTEMI). Methods and Results In a retrospective cohort study of all diagnosed NSTEMI in US Veterans Affairs Healthcare System from January 1, 2019 to October 30, 2022 (n=67 125), outcomes compared between prepandemic period 6 unique pandemic phases: (1) acute phase, (2) community spread, (3) first peak,...
Many AR and VR task domains involve manipulating virtual objects; for example, to perform 3D geometric transformations. These operations are typically accomplished with tracked hands or hand-held controllers. However, there some activities in which the user's already busy another task, requiring user temporarily stop what they doing second while also taking time disengage reengage original (e.g., putting down picking up tools). To avoid need overload this way an system guiding a physician...
During a vascular intervention (a type of minimally invasive surgical procedure), physicians maneuver catheters and wires through patient's blood vessels to reach desired location in the body. Since relevant anatomy is typically not directly visible these procedures, virtual reality augmented systems have been developed assist 3D navigation. Because both physician's hands may already be occupied, we an system supporting hands-free interaction techniques that use voice head tracking enable...
Augmented reality (AR) holds great potential for IR by integrating virtual 3D anatomic models into the real world.1 In this pilot study, we developed an AR guidance system cerebral angiography, evaluated its impact on radiation, contrast, and fluoroscopy time, assessed physician response. prospective 9 patients with CT or MR imaging of aorta underwent diagnostic neuroangiography from June to August 2017. Before each procedure, segmentation software was used create a model patient’s aortic...
Abstract Background Cardiovascular procedural treatments were deferred at scale during the COVID-19 pandemic, with unclear impact on patients presenting Non-ST Elevation Myocardial Infarction (NSTEMI). Methods In a retrospective cohort study of all diagnosed NSTEMI in U.S. Veterans Affairs Healthcare System from 1/1/19 to 10/30/22 (n=67,125), and outcomes compared between pre-pandemic period six unique pandemic phases (1: Acute phase, 2: Community spread, 3: First Peak, 4: Post-Vaccine, 5....
Background: Hypertrophic cardiomyopathy (HCM) is defined by the presence of significant left ventricular hypertrophy (LVH) in absence secondary factors like systemic hypertension, aortic stenosis, and athlete's heart syndrome.Case presentation:A 67-year-old woman, with a complaint severe fatigue, peripheral cyanosis on normal daily activity life, paroxysmal nocturnal dyspnea, was admitted to Cardiac Care Unit, Razavi Hospital, Mashhad, Iran. In primary physical examination, cardiac...
Background: Importance of diversity in clinical trial participants has been recently highlighted. Though trials led by women principal investigators (PIs) are more likely to enroll diverse participants, the proportion PIs is unknown. Objective: To evaluate gender distribution among who conduct NIH and industry-funded cardiac electrophysiology (EP). Methods: clinicaltrials.gov registry completed between 1/1/2002 12/31/2021 atrial fibrillation (AF), implantable cardioverter defibrillators...
Background: The popularity of complementary and alternative medicine is on the rise. Objectives: current study aimed to compare effect vaginal royal jelly with intrauterine insemination (IUI) sub-fertility in men. Methods: sample size was estimated as 27 subjects, based a power confidence interval 80% 95%, respectively. conducted Mashhad, Northeast Iran, from 2015 2017. Men (asthenozoospermia, defined total sperm motility below 40% concentration 20 million/mL), healthy wives, salpingography,...
