Pulmonary embolism (PE) can result in rapid clinical decompensation in many patients. With increasing patient complexity and advanced treatment options for PE, multidisciplinary, rapid response teams can optimize risk stratification and expedite management strategies. The Massive And Submassive Clot On-call Team (MASCOT) was created at our institution, which comprised specialists from cardiology, pulmonology, hematology, interventional radiology, and cardiac surgery. MASCOT offers rapid consultation 24 hours a day with a web-based conference call to review patient data and discuss management of patients with high-risk PE...

BACKGROUND AND PURPOSE: Multicenter clinical trials attempt to select sites that can move rapidly to randomization and enroll sufficient numbers of patients. However, there are few assessments of the success of site selection. METHODS: In the CREST-2 (Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trials), we assess factors associated with the time between site selection and authorization to randomize, the time between authorization to randomize and the first randomization, and the average number of randomizations per site per month...

INTRODUCTION: Arterial pseudoaneurysms are well known iatrogenic complication of percutaneous angiographic or interventional vascular procedures. In the past, the definitive treatment option was open surgical repair which is a relatively invasive procedure. In the last few years, Ultrasound (US) guided percutaneous thrombin injection has been gaining popularity as definitive treatment of pseudoaneurysms. AIM: To evaluate efficacy and safety of US guided percutaneous injection of thrombin for treatment of iatrogenic femoral pseudoanurysms at a tertiary care interventional radiological and cardiology centre...

Increasing operator experience and newer available interventional cardiology devices require reassessment of radiological risk related to percutaneous coronary interventions (PCI). We aimed at comparison of radiological risk and procedural data of PCIs performed by radial (RA) and femoral (FA) approach in real life patients. Detailed retrospective analysis of 1500 consecutive PCIs with the use of radial or femoral access was performed. Comparison between RA and FA groups included procedural time (PT), fluoroscopy time (FT), radiation dose and contrast volume usage...

BACKGROUND: Interventional radiology and cardiology procedures contribute significantly to the collective dose of radiation exposure from medical interventions. Recent and dedicated studies comparing directly these procedures in term of patient radiation exposure are lacking. Our aim was to compare radiation exposure among different interventional procedures performed under fluoroscopic guidance. METHODS: The RODEO study (NCT: 02972736) is an international observational retrospective multicenter study enrolling all patients undergoing diagnostic or interventional procedures performed by different interventional operators (i...

The prevalence of peripheral artery disease (PAD) is continuously increasing. In addition, the treatment of PAD has changed substantially over the last decades. Novel treatment modalities and diagnostic tools were developed and endovascular therapy was established as a first-line therapy. In consequence, vascular medicine has become an interdisciplinary field, involving different specialties such as internal medicine/cardiology, internal medicine/angiology, vascular surgery, and (interventional) radiology. Attributed to the expanding field and to ensure high quality and standardized training, various curricula were developed...

Pulmonary embolism (PE) is a serious and prevalent cause of vascular disease. Nevertheless, optimal treatment for many phenotypes of PE remains uncertain. Treating PE requires appropriate risk stratification as a first step. For the highest-risk PE, presenting as shock or arrest, emergent systemic thrombolysis or embolectomy is reasonable, while for low-risk PE, anticoagulation alone is often chosen. Normotensive patients with PE but with indicia of right heart dysfunction (by biomarkers or imaging) constitute an intermediate-risk group for whom there is controversy on therapeutic strategy...

In accordance with recommendations by the International Commission on Radiological Protection, the current European Basic Safety Standards has adopted a reduced occupational eye lens dose limit of 20 mSv yr(-1). The radiation safety implications of this dose limit is of concern for clinical staff that work with relatively high dose x-ray angiography and interventional radiology. Presented in this work is a thorough assessment of the occupational eye lens dose based on clinical measurements with active personal dosimeters worn by staff during various types of procedures in interventional radiology, cardiology and neuroradiology...

PURPOSE: To evaluate the sensitivity of the Diagnostic Radiological Index of Protection (DRIP) to procedural factors in fluoroscopy in an effort to determine an appropriate set of scatter-mimicking primary beams (SMPB) to be used in measuring the DRIP. METHODS: A series of clinical and factorial Monte Carlo simulations were conducted to determine the shape of the scattered X-ray spectra incident on the operator in different clinical fluoroscopy scenarios. Two clinical evaluations studied the sensitivity of the scattered spectrum to gantry angle and patient size while technical factors were varied according to measured automatic dose rate control (ADRC) data...

Interventional radiology and cardiology guarantee high benefits for patients, but are known to be associated with a high level of radiation exposure of medical staff. The recently suggested decrease of the annual dose limit for the eye lens, from 150 to 20 mSv, caused a need for a reconsideration of practices ensuring sufficient protection for the lens of the eyes of medical staff. In such context the study of the scattered radiation around the operator's head could help in finding the best solutions to be adopted for the ceiling-suspended shield and lead glasses in the most common situations in interventional practices...

Percutaneous left atrial appendage (LAA) closure is a routinely performed method to reduce the risk of stroke in patients suffering from atrial fibrillation, when an oral anticoagulation is no longer indicated due to relevant bleeding complications. Currently, the Amplatzer Amulet and the Watchman system are two equally used systems. While there is an acute success rate of more than 95 per cent for this intervention, several minor and major complications such as pericardial effusions, air embolism, vascular lesions in proximity to the heart or even death can occur...

Physicians and Internists in India have tended to brush under the carpet legal issues affecting their profession. Of concern to all Physicians is the judgment in a recent case where the NCDRC has stated that if MD Medicine Physicians write Physician & Cardiologist on their letterhead it is Quackery. What is MD Medicine degree holder in India qualified and trained to treat ? These are issues which need debate and that can only be initiated once we recognize that there is a problem. Either an MD Medicine is a cardiologist or he is not...
