A Machine Learning Model Using Cardiac CT and MRI Data Predicts Cardiovascular Events in Obstructive Coronary Artery Disease.

Background Multimodality imaging is essential for personalized prognostic stratification in suspected coronary artery disease (CAD). Machine learning (ML) methods can help address this complexity by incorporating a broader spectrum of variables. Purpose To investigate the performance of an ML model that uses both stress cardiac MRI and coronary CT angiography (CCTA) data to predict major adverse cardiovascular events (MACE) in patients with newly diagnosed CAD.

Novel Cardiokine GDF3 Predicts Adverse Fibrotic Remodeling After Myocardial Infarction.

Background: Myocardial infarction (MI) induces a repair response that ultimately generates a stable fibrotic scar. Although the scar prevents cardiac rupture, an excessive profibrotic response impairs optimal recovery by promoting the development of noncontractile fibrotic areas. The mechanisms that lead to cardiac fibrosis are diverse and incompletely characterized.

[Nasopharyngeal carriage of SARS-CoV-2 among health personnel with symptoms suggestive of COVID-19 in a University Hospital in the Paris suburbs].

Introduction: A consultation dedicated to symptomatic health professionals was opened at the beginning of the COVID-19 epidemic in order to meet the specific needs of this population. The objective of this work was to estimate the frequency of SARS-Cov-2 nasopharyngeal carriage in symptomatic healthcare workers suspected of having COVID-19 and to determine the factors associated with this carriage.

Methods: Of the 522 consultants, 308 worked in the Hospital and 214 outside.

VEGF-A plasma levels are associated with microvascular obstruction in patients with ST-segment elevation myocardial infarction.

Background: Microvascular obstruction (MVO) is associated with poor outcome after ST-segment elevation myocardial infarction (STEMI). Vascular endothelial growth factor-A (VEGF-A) is a vascular permeability inducer playing a key role in MVO pathogenesis. We aimed to assess whether VEGF-A levels are associated with MVO, when evaluated by magnetic resonance imaging (MRI) in STEMI patients.

Contribution of echocardiography in the diagnosis of definitive infective endocarditis: the infectious disease specialist's point of view.

In 1994, the original Duke criteria introduced the usefulness of echocardiography for the diagnosis of definitive infective endocarditis (IE). Recently, the European Society of Cardiology (ESC) highlighted the need of complementary imaging to support the diagnosis of embolic events and cardiac involvement when echocardiography findings are negative or doubtful. We decided to study the usefulness of transthoracic and transesophageal echocardiography (TTE/TEE) for the diagnosis of definitive IE in patients who already benefited from complementary investigations.

[Risk stratification of sudden death in hypertrophic cardiomyopathy in 2016].

Patients with hypertrophic cardiomyopathy (HCM) are at an increased risk of death from many causes and sudden cardiac death is one of them. The study of the sudden cardiac death of patients with HCM has allowed the identification of risk factors and among them major risk factor are: family history of sudden cardiac death, the occurrence of syncope/dizziness, the existence of non-sustained ventricular tachycardia an abnormal blood pressure response during stress test, presence of severe left ventricular hypertrophy≥30mm. Risk stratification for sudden cardiac death is essential, for symptomatic or asymptomatic HCM patients.

Diffusion-weighted MR imaging of uterine leiomyomas following uterine artery embolization.

Purpose: To test whether variations in apparent diffusion coefficient (ADC) values of uterine leiomyomas after uterine artery embolization (UAE) may correlate with outcome and assess the effects of UAE on leiomyomas and normal myometrium with magnetic resonance imaging (MRI).

Methods: Data of 49 women who underwent pelvic MRI before and after UAE were retrospectively reviewed. Uterine and leiomyoma volumes, ADC values of leiomyomas, and normal myometrium were calculated before and after UAE.

Comparison between visual grading and planimetric quantification of microvascular obstruction extent assessment in reperfused acute myocardial infarction.

Objectives: Current methods for infarct size and microvascular obstruction (MVO) quantification by cardiac magnetic resonance (CMR) imaging rely on planimetry. This method is time-consuming. We sought to evaluate a direct assessment of MVO severity based on visual evaluation and to compare it to a reference method.

Major complications due to transjugular liver biopsy: Incidence, management and outcome.

Purpose: The purpose of this study was to retrospectively evaluate the incidence of intraperitoneal bleeding and other major complications of transjugular liver biopsy (TJLB) and analyze their outcome and management.

Materials And Methods: The clinical files of 341 consecutive patients who had TJLB were retrospectively analyzed. There were 237 men and 104 women (mean age: 51.

Transcatheter Arterial Embolization for Postpartum Hemorrhage: Indications, Technique, Results, and Complications.

Postpartum hemorrhage (PPH) is a potentially life-threatening condition, which needs multidisciplinary management. Uterine atony represents up to 80 % of all causes of PPH. Transcatheter arterial embolization (TAE) has now a well-established role in the management of severe PPH.

Establishment of diagnostic reference levels in cardiac CT in France: a need for patient dose optimisation.

The objective of this study was to propose diagnostic reference levels (DRLs) for coronary computed tomography angiography (CCTA), in the context of a large variability in patient radiation dose, and the lack of European recommendations. Volume Computed Tomography Dose Index (CTDIvol) and dose-length product (DLP) were collected from 460 CCTAs performed over a 3-month period at eight French hospitals. CCTAs (∼50 per centre) were performed using the routine protocols of the centres, and 64- to 320-detector CT scanners.

Role and Effectiveness of Percutaneous Arterial Embolization in Hemodynamically Unstable Patients with Ruptured Splanchnic Artery Pseudoaneurysms.

Purpose: To assess the role and effectiveness of percutaneous arterial embolization (TAE) in patients with hemodynamic instability due to hypovolemic shock secondary to ruptured splanchnic artery pseudoaneurysms (SAPA).

Materials And Methods: Seventeen patients (11 men, 6 women; mean age, 53 years) with hemodynamic instability (systolic blood pressure <90 mmHg) due to hypovolemic shock secondary to ruptured SAPA were treated by TAE. Clinical files, multidetector row computed tomography angiography, and angiographic examinations along with procedure details were reviewed.

Three-dimensional MDCT angiography of splanchnic arteries: pearls and pitfalls.

Fast scanning along with high resolution of multidetector computed tomography (MDCT) have expanded the role of non-invasive imaging of splanchnic arteries. Advancements in both MDCT scanner technology and three-dimensional (3D) imaging software provide a unique opportunity for non-invasive investigation of splanchnic arteries. Although standard axial computed tomography (CT) images allow identification of splanchnic arteries, visualization of small or distal branches is often limited.

Vitamin K1 antagonisation is not safe in high thromboembolic risk patients with over-anticoagulation.

We report a case of a fatal massive anterior acute myocardial infarction (AMI) after administration of vitamin K1 for over-anticoagulation following cardioembolism from mechanical mitroaortic valve prostheses associated with atrial fibrillation.

Postpartum hemorrhage resulting from pelvic pseudoaneurysm: a retrospective analysis of 588 consecutive cases treated by arterial embolization.

Objective: This study was designed to determine the incidence of arterial pseudoaneurysm in patients presenting with postpartum hemorrhage (PPH), to analyze the angiographic characteristics of pseudoaneurysms that cause PPH, and to evaluate the effectiveness of pelvic arterial embolization for the treatment of this condition.

Study Design: Eighteen women with pelvic arterial pseudoaneurysm were retrieved from a series of 588 consecutive patients with PPH treated by arterial embolization. Clinical files, angiographic examinations, and procedure details were reviewed.

Diagnostic performance of computed tomography coronary angiography (from the Prospective National Multicenter Multivendor EVASCAN Study).

Computed tomographic coronary angiography (CTCA) has been proposed as a noninvasive test for significant coronary artery disease (CAD), but only limited data are available from prospective multicenter trials. The goal of this study was to establish the diagnostic accuracy of CTCA compared to coronary angiography (CA) in a large population of symptomatic patients with clinical indications for coronary imaging. This national, multicenter study was designed to prospectively evaluate stable patients able to undergo CTCA followed by conventional CA.
