Training and Verification Requirements for Interpretation of Cardiac CT and MRI: Expert Panel Narrative Review.

The use of cardiac CT and MRI is rapidly expanding based on strong evidence from large international trials. The number of physicians competent to interpret cardiac CT and MRI may be unable to keep pace with the increasing demand. Societies and organizations have prescribed training requirements for interpreting cardiac CT and MRI, with recent updates focusing on the increased breadth of competency that is now required due to ongoing imaging advances.

Multimodality Imaging of Infective Endocarditis.

Infective endocarditis (IE) is a complex multisystemic disease resulting from infection of the endocardium, the prosthetic valves, or an implantable cardiac electronic device. The clinical presentation of patients with IE varies, ranging from acute and rapidly progressive symptoms to a more chronic disease onset. Because of its severe morbidity and mortality rates, it is necessary for radiologists to maintain a high degree of suspicion in evaluation of patients for IE.

Registry of Aortic Diseases to Model Adverse Events and Progression (ROADMAP) in Uncomplicated Type B Aortic Dissection: Study Design and Rationale.

Purpose: To describe the design and methodological approach of a multicenter, retrospective study to externally validate a clinical and imaging-based model for predicting the risk of late adverse events in patients with initially uncomplicated type B aortic dissection (uTBAD).

Materials And Methods: The Registry of Aortic Diseases to Model Adverse Events and Progression (ROADMAP) is a collaboration between 10 academic aortic centers in North America and Europe. Two centers have previously developed and internally validated a recently developed risk prediction model.

Post-Lung Transplantation Outcomes and Ex Vivo Histopathological Findings in Severe Post-Covid-19 Pulmonary Disease-A Single-Center Experience.

Background: A significant proportion of patients with severe and persistent coronavirus disease 2019 (COVID-19) require continuous ventilatory support and occasional extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome (ARDS). Lung transplantation is a treatment option for patients who develop severe ARDS.

Methods: Our lung transplant database was retrospectively reviewed for patients who underwent lung transplantation for COVID-19 pulmonary disease at Memorial Hermann Hospital, Texas Medical Center, Houston, Texas, from January 2020 to March 2022.

Pre- and Postprocedure Imaging of Transcatheter Pulmonary Valve Implantation.

Transcatheter pulmonary valve replacement (TPVR) is a minimally invasive procedure for treatment of right ventricular outflow tract (RVOT) dysfunction in surgically repaired congenital heart diseases. TPVR is performed in these patients to avoid the high risk and complexity of repeat surgeries. Several TPVR devices are now available to be placed in the right ventricle (RV) to pulmonary artery (PA) conduit, native RVOT, or surgical bioprosthetic valves.

An unusual cause of acute pericarditis: a case report.

Background: Inflammation of the pericardium, or pericarditis, is a frequent cause of acute chest pain in young patients. Pericarditis is typically associated with viral infections, but other potential causes may have distinct prognostic and therapeutic implications.

Case Summary: A 26-year-old man presented with typical signs and symptoms of acute pericarditis.

Correlating computed tomography pulmonary angiography signs of right ventricular strain in pulmonary embolisms to clinical outcomes.

Introduction: Right ventricular strain (RVS) in pulmonary embolism (PE) can be used to stratify risk and direct intervention. The clinical significance of computed tomography pulmonary angiogram (CTPA)-derived radiologic signs of RVS, however, remains incompletely characterized. We retrospectively analyzed a cohort of persons with acute PE to determine which, if any, findings of RVS on CTPA correlate with clinical outcomes.

The emerging spectrum of cardiopulmonary pathology of the coronavirus disease 2019 (COVID-19): Report of 3 autopsies from Houston, Texas, and review of autopsy findings from other United States cities.

This paper collates the pathological findings from initial published autopsy reports on 23 patients with coronavirus disease 2019 (COVID-19) from 5 centers in the United States of America, including 3 cases from Houston, Texas. Findings confirm that COVID-19 is a systemic disease with major involvement of the lungs and heart. Acute COVID-19 pneumonia has features of a distinctive acute interstitial pneumonia with a diffuse alveolar damage component, coupled with microvascular involvement with intra- and extravascular fibrin deposition and intravascular trapping of neutrophils, and, frequently, with formation of microthombi in arterioles.

Wisdom Tooth's Revenge: Retropharyngeal Abscess and Mediastinitis after Molar Tooth Extraction.

Retropharyngeal abscess is potentially associated with high morbidity and mortality as a result of its direct anatomical connection with the mediastinum. Therefore, knowledge of the relevant anatomy is essential for recognizing the presence and extent of disease in a timely manner. In this case report, we aim to review the pertinent anatomy and patterns of spread of infection from a full blown deep neck space infection to result in mediastinitis and empyema.

Thoracic venous injuries: an imaging and management overview.

Thoracic venous injuries are predominantly attributed to traumatic and iatrogenic causes. Gunshot wounds and knife stabbings make up the vast majority of penetrating trauma whereas motor vehicle collisions are the leading cause of blunt trauma to the chest. Iatrogenic injuries, mostly from central venous catheter complications are being described in growing detail.
