Role of cardiac and lung ultrasound in the COVID-19 era.

Minerva Cardiol Angiol 2022 Jun 29. Epub 2022 Jun 29.

Unit of Cardiovascular Disease, Cardiovascular Department, Poliambulanza Foundation, Brescia, Italy -

SARS-CoV-2 mainly affects the respiratory system, from mild upper respiratory symptoms in acute respiratory distress syndrome. However, a significant amount of evidence has demonstrated that Coronavirus disease 2019 affects the cardiovascular system in many ways and has manifestations ranging from asymptomatic increases in cardiac biomarkers for cardiovascular and cardiac collapse arrest. The primary diagnostic method of COVID-19 is reverse transcription polymerase chain reaction of the nucleic acid of SARS-CoV-2 in nasopharyngeal swabs. Read More

Transesophageal echocardiography in the emergency department: A comprehensive guide for acquisition, implementation, and quality assurance.

J Am Coll Emerg Physicians Open 2022 Jun 17;3(3):e12758. Epub 2022 Jun 17.

Department of Emergency Medicine Beaumont Hospital Royal Oak Michigan USA.

Echocardiography is an essential tool in emergency medicine, yielding valuable information for physicians that directly affects diagnostic and management strategies. Emergency department (ED) transesophageal echocardiography (TEE) is an increasingly common procedure performed in a variety of institutions, allowing for ongoing cardiac imaging during cardiopulmonary resuscitation as well as providing high-resolution assessment of both cardiac and aortic anatomy. However, despite the numerous benefits of ED TEE, the process of implementing this modality within a department is difficult because of unique process and cost considerations. Read More

Blunted cardiovascular effects of beta-blockers in patients with cirrhosis: Relation to severity?

PLoS One 2022 28;17(6):e0270603. Epub 2022 Jun 28.

Department of Clinical Medicine, Copenhagen University Hospital Hvidovre, Hvidovre, Denmark.

Aims: Patients with cirrhosis and portal hypertension are at high risk of developing complications such as variceal hemorrhage, ascites, and cardiac dysfunction, the latter of which is known as cirrhotic cardiomyopathy. Since non-selective beta-blockers (NSBB) may aggravate hemodynamic complications we investigated the effect of real-time propranolol infusion on cardiac function in patients with varying degrees of cirrhosis.

Methods: Thirty-eight patients with Child-Pugh A (n = 17), B (n = 17) and C (n = 4) underwent liver vein catheterization and cardiac magnetic resonance imaging. Read More

Supracardiac Total Anomalous Pulmonary Venous Return Repair in a 7-Month-Old Infant.

Tex Heart Inst J 2022 May;49(3)

Department of Congenital Heart Surgery, University Hospital Center Zagreb, Zagreb, Croatia.

Total anomalous pulmonary venous return is a congenital heart malformation characterized by anomalous pulmonary venous inflow to the right atrium. Surgical repair typically occurs during the first month of life, and survival beyond that age in untreated patients is unlikely. We report an extreme case of supracardiac total anomalous pulmonary venous return in an infant who survived 7 months despite atypical anomalous inflow without atrial-level communication and with right-to-left shunting only through a patent ductus arteriosus.

Imaging of left heart intracardiac thrombus: clinical needs, current imaging, and emerging cardiac magnetic resonance techniques.

Ther Adv Cardiovasc Dis 2022 Jan-Dec;16:17539447221107737

Department of Radiology, Keck School of Medicine, University of Southern California, 2250 Alcazar Street, CSC Room 104, Los Angeles, CA 90033, USA.

Intracardiac thrombus in the left atrium and atrial appendage (LA/LAA) and left ventricle (LV) increases the risk of systemic thromboembolism and causes potentially devastating diseases such as ischemic stroke and acute ischemia in abdominal organs and lower extremities. Detecting the presence and monitoring the resolution of left heart intracardiac thrombus are of vital importance for stratifying patients and guiding treatment decisions. Currently, echocardiography is the most frequently used method for the above clinical needs, followed by computed tomography. Read More

Association of ambulatory blood pressure with aortic valve and coronary artery calcification.

J Hypertens 2022 Jul;40(7):1344-1351

NCD Epidemiology Research Center, Shiga University of Medical Science, Otsu.

Objective: We aimed to investigate the effect of ambulatory blood pressure (BP) on aortic valve calcification (AVC) and coronary artery calcification (CAC), which are subclinical atherosclerotic diseases.

Methods: In this population-based, cross-sectional study, we assessed office BP, mean ambulatory BP (24-h, awake, and asleep), and variability of ambulatory BP, as determined by the coefficient of variation (awake and asleep). AVC and CAC were quantified using an Agatston score (>0) based on computed tomography scanning. Read More

Radiol Cardiothorac Imaging 2022 Jun 9;4(3):e220008. Epub 2022 Jun 9.

Department of Diagnostic Imaging, Warren Alpert Medical School of Brown University, Providence, RI, USA.

By comparing phenotypic clinical characteristics and cardiovascular magnetic resonance (CMR) findings in 14 patients with COVID-19 mRNA vaccine-associated myocarditis to 14 patients with acute myocarditis from other causes, we found that patients with COVID-19 vaccination- associated acute myocarditis have higher left ventricular ejection fraction, higher left ventricular global circumferential and radial strain, and less involvement of late gadolinium enhancement in the septal segments with less involvement of midmyocardial pattern of late gadolinium enhancement, compared to patients with acute myocarditis from other causes.
