Review Multicenter StudyContemporary use of cardiac imaging for COVID-19 patients: a three center experience defining a potential role for cardiac MRI.
The pandemic of coronavirus disease 2019 (COVID-19) secondary to the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has bestowed an unprecedented challenge upon us, resulting in an international public health emergency. COVID-19 has already resulted in > 1,600,000 deaths worldwide and the fear of a global economic collapse. SARS-CoV-2 is notorious for causing acute respiratory distress syndrome, however emerging literature suggests various dreaded cardiac manifestations associated with high mortality. ⋯ Cardiac manifestations from COVID-19 include but are not limited to, acute myocardial injury, cardiac arrhythmias, congestive heart failure and acute coronary syndrome. Cardiac imaging is paramount to appropriately diagnose and manage the cardiac manifestations of COVID-19. Herein, we present cardiac imaging findings of COVID-19 patients with biomarker and imaging confirmed myocarditis to provide insight regarding the variable manifestations of COVID-19 myocarditis via Cardiac MRI (CMR) coupled with CMR-edema education along with recommendations on how to incorporate advanced CMR into the clinicians' COVID-19 armamentarium.

ReviewEndovascular therapy for acute severe pulmonary embolism.
Acute pulmonary embolism (PE) is a major public health problem and accounts for 100,000-180,000 deaths per year in the United States. Current prognostic stratification separates acute PE into massive, submassive, and low-risk by the presence or absence of sustained hypotension, RV dysfunction, and myocardial necrosis. Massive, submassive and low-risk PE have mortality rates of 25-65%, 3%, and < 1%, respectively. In this review we will focus on therapies currently available to manage acute massive and submassive PE.

ReviewCardiac CT angiography for evaluation of acute chest pain.
Chest pain is the second most common emergency department (ED) presentation in the United States. Cardiac computed tomography angiography (CCTA) now plays an important role in the evaluation of patients with suspected acute coronary syndrome in the ED setting. In this article, we review the available techniques focused on the use of CCTA to evaluate patients fosr coronary atherosclerosis for timely triage of acute chest pain.

Meta AnalysisTwo-dimensional echocardiography using second harmonic imaging for the diagnosis of intracardiac right-to-left shunt: a meta-analysis of prospective studies.
Right-to-left shunting (RLS), usually through a patent foramen ovale (PFO), has been associated with migraine, cryptogenic stroke and hypoxemia. With emerging observational studies and clinical trials on the subject of PFO, there is a need for accurate diagnosis of PFO in patients being considered for transcatheter closure. While transesophageal echo (TEE) bubble study is the current standard reference for diagnosing PFO, transthoracic echo with second harmonic imaging (TTE-HI) may be a preferable screening test for RLS due to its high accuracy and non-invasiveness. ⋯ TTE-HI is a reliable, non-invasive test with proficient diagnostic accuracies. The high sensitivity and specificity of TTE-HI make it a useful initial screening test for RLS. If the precise anatomy is required, then TEE can be obtained before scheduling a patient for transcatheter PFO closure.

Review Meta AnalysisDiagnostic accuracy of first generation dual-source computed tomography in the assessment of coronary artery disease: a meta-analysis from 24 studies.
The objective of this study is to evaluate the diagnostic accuracy of the first generation dual-source computed tomography (DSCT) in the diagnosis of coronary artery disease (CAD). We selected articles from four databases (Pubmed, Embase, the Cochrane central register of controlled trials (CENTRAL) and Chinese biomedical literature database. The strict study selection was made, and two reviewers independently extracted data back-to-back from included studies. ⋯ The area under the receiver operating characteristic curve (AUC) in the two subgroups were 0.9608 and 0.9786, respectively. DSCT is highly sensitive for patient-based analysis of CAD and has high specificity and NPV for segment-based analysis of CAD. First generation DSCT may have a role in the evaluation of patients with chest pain as a simple non-invasive examination because of its ability to diagnose or exclude significant CAD.
