QFR-guided intervention, like FFR-guided intervention, is superior to angiographically guided intervention in terms of MACE. Also, very interesting to note is that the annual number of publications of the QFR continues to increase sharply and has surpassed the iFR publications! ...
Patients are contraindicated if they have been assessed to have bilateral carotid bifurcations located above the level of the mandible, baroreflex failure or autonomic neuropathy, uncontrolled symptomatic cardiac bradyarrhythmias, carotid atherosclerosis that is determined by ultrasound or angiographic evaluation greater than 50%, ulcerative plaques in the carotid artery as ...

The use of computer vision in radiology may have advantages for both patients and medical facilities. However, some worry that machine learning (ML) may one day replace doctors because it can outperform them. The desire for increased efficiency and efficacy in clinical care has been the primary motivating reason behind the development of AI in medical imaging. Recent technological developments, ...
Background This paper outlines the first in-patient implantation of the EluNIR™ ridaforolimus eluting elastomeric stent (Medinol Ltd.). This complex case involved a patient with a flow-limiting lesion in a native coronary artery post bypass surgery. The new EluNIR stent system includes a stent with a low metal footprint which comprises struts of variable width: ultra-narrow struts having ...

Background: This paper describes a challenging case of implantation of the EluNIR™ Ridaforolimus eluting elastomeric stent (Medinol Ltd.). This complex case involved a patient with a flow-limiting lesion in a native coronary artery post bypass surgery. The new EluNIR stent system includes a stent with a low metal footprint that comprises struts of variable width: ultra-narrow struts ...

A cyclo-ergometer exercise test was performed on this 57-year old male patient. He is a smoker with a family background of CAD. He is suffering from left bundle branch block making ST-segment analysis impossible. The patient has achieved 78 % of max. heart rate at 120 watts. Moderate paleness and dyspnoea have been observed at the end of the 120 watts step. However, after a normal initial ...
Micromate™ Case Report series presents real cases performed by the physicians currently using our full-fledged robotic platform for percutaneous procedures. Today, we join Dr. Alexander Kupferthaler, Interventional Radiologist at the Ordensklinikum Linz – Barmherzige Schwestern, for a robot-guided bone biopsy. Clinical Context 65-year-old female with invasive lobular carcinoma of ...
Micromate™ Case Report series presents real cases performed by the physicians currently using the world’s smallest robot for percutaneous procedures. Today, we join Drs. Gerlig Widmann and Martin Freund, Interventional Radiologists at the Tirol Kliniken, for a robot-guided type II endoleak embolization. Clinical Context Patient’s profile: Male patient, previously subjected ...
When automated dark adaptometry was first commercialized, many of us had more questions than answers with regard to using this information for detecting AMD and monitoring disease progression. But with more than seven years of practical in-office experience performing dark adaptation testing on thousands of patients, the tables have turned. This technology offers a safety net for ...
ABSTRACT Infection of prosthetic vascular grafts can manifest as pain, pseudoaneurysms, or arterial insufficiency in the leg. We present the case of a female patient with a medical history of a right external iliac artery endofibrosis, with a persistently infected synthetic iliofemoral bypass graft, which we replaced with a bioengineered human acellular vessel. At the 12-month follow-up visit, ...
For this reason we studied a cohort of these patients looking for the relationship between SAD and MAC and the clinical outcomes.8 The SAD score was obtained on the baseline angiographic study, whereas for MAC we proposed a new calcium score founded on plain foot radiograph (Figure 2).2,8 Figure 1. ...
By combining different cell populations in a fibrin bioink, researchers from Trinity College Dublin, Royal College of Surgeons in Ireland and University of Illinois Chicago were able to sprout an in vitro microvessel network that was then exploited to prevascularise a 3D printed scaffold implanted in a critical size femoral defect using REGENHU bioprinter. This dual approach was observed to ...

February 9, 2021—Findings from the first-in-human (FIH) study assessing the safety and feasibility of the Bashir endovascular catheter (BEC; Thrombolex, Inc.) for the treatment of acute intermediate-risk pulmonary embolism (PE) were published by Akhilesh K. Sista, MD, et al in Circulation: Cardiovascular Intervention (2021;14). The BEC is a pharmacomechanical device designed to enhance ...
In Figure 2, we present a 3-level SAD score based on visual estimation of the angiographic imaging.2 SAD is strongly associated with medial artery calcification (MAC),3 which appears as a typical rail-track pattern of calcium, spreading in the entire vascular tree. ...
Abstract Numerous clinical studies using coronary computed tomography angiography (CTA) and conventional invasive coronary angiography (ICA) confirmed the strong relation between atherosclerotic disease burden and risk of adverse events. Few studies have compared coronary CTA and ICA regarding semiquantitative plaque burden measurements, reproducibility, and cardiovascular risk assessment. ...
Abstract The heritability of coronary atherosclerotic plaque burden, coronary geometry, and phenotypes associated with increased cardiometabolic risk are largely unknown. The primary aim of the Burden of Atherosclerotic Plaques Study in Twins-Genetic Loci and the Burden of Atherosclerotic Lesions (BUDAPEST-GLOBAL) study is to evaluate the influence of genetic and environmental factors on the ...
Several studies have revealed that interventional radiography procedures performed in cardiology departments are high dose techniques. In this study, effective dose of cardiologists working in hospitals Catheterisation Laboratories (CATHLABs) in Mashhad city have been measured during Coronary Angiography (CA) and Percutaneous Transluminal Coronary Angioplasty (PTCA) procedures. In order to ...
Population exposure to diagnostic and therapeutic ionising radiation is likely to increase worldwide, and this has raised concerns about the stochastic effects of low doses of radiation exposure. The present study was aimed to study the incidence of Chromosomal Aberrations (CAs) in patients exposed to low doses of X-rays during diagnostic interventional radiological procedures. Peripheral blood ...
Pathological examination confirmed the angiographic patency rate and did not reveal injury secondary to ultrasound in the skin, soft tissues, heart, or lungs. ...
