The mechanism and severity of mitral valve (MV) regurgitation (MR) play a critical role in guiding treatment decisions. Transthoracic echocardiography (TTE) is the primary diagnostic modality for evaluating MV disease. Discordant findings on TTE can be further quantified through transesophageal echocardiography (TEE).

- COVID-19 has been linked to a higher risk of ischemic stroke, but the role of echocardiography in assessing this risk in hospitalized patients hasn't been researched before.
- A study analyzed 368 COVID-19 patients who underwent echocardiography, revealing that 13.3% of them suffered from ischemic strokes, particularly those with left atrial dilation and left ventricular thrombus.
- The newly developed COVID-19 Ischemic Stroke Risk Score effectively uses both clinical and echocardiographic factors to estimate the stroke risk, indicating echocardiography's value in this context.
Autosomal dominant polycystic kidney disease (ADPKD) eventually leads to end stage renal disease (ESRD) with an increase in size and number of cysts over time. Progression to ESRD has previously been shown to correlate with total kidney volume (TKV). An accurate and relatively simple method to perform measurement of TKV has been difficult to develop.

They are typically located on the left-sided heart valves and are concerning primarily due to their risk for embolization into the periphery. Right-sided PFE, however, is very rare and their management is not well known.

Methods: A 12-month retrospective review was performed of all CCTAs at a single institution. Coronary arterial dominance, Agatston score and presence or absence of cardiovascular risk factors including hypertension (HTN), hyperlipidemia (HLD), diabetes and smoking were recorded.
Article Synopsis
- - Recent research indicates that coronary artery calcification (CAC) can help predict severe outcomes in COVID-19 patients, particularly with comorbid cardiovascular disease.
- - In a study of 180 COVID-19 patients, those with detected CAC were significantly more likely to require intubation or face mortality, with severe CAC showing even higher risks.
- - The study concluded that both the severity of CAC and the number of arteries affected correlated with worse outcomes, while prior surgeries like coronary artery bypass grafting or stenting did not significantly impact patient mortality or intubation rates.

- * In a cohort of 305 hospitalized patients, 62.3% exhibited myocardial injury, evidenced by abnormal electrocardiograms and echocardiograms indicating left ventricular and right ventricular dysfunction.
- * The findings showed that in-hospital mortality rates increased significantly with the presence of myocardial injury and echocardiographic abnormalities, linking these conditions to a greater risk of death during hospitalization.
Acute aortic syndrome (AAS) is an emergency and life-threatening condition including aortic dissection, intramural hematoma, penetrating atherosclerotic ulcer and iatrogenic-traumatic aortic injury. An integrated multiparametric approach (clinical history and examination, electrocardiogram, biomarkers and imaging techniques) is recommended in order to make timely and accurate diagnosis, delineate the prognosis, choose the most appropriate therapeutic interventions tailored for the individual patient. Nowadays the best imaging strategy for diagnosing AAS and its complications is a combination of transthoracic echocardiography and computed tomography angiography (CTA).

Methods: In this retrospective study, 130 cancer patients with central venous catheters undergoing CMR from August 2012-January 2018 were included. CMR (cine-CMR and DE-CMR) and echocardiography were interpreted for RA thrombus blinded to other imaging results and clinical data.
Background: Non-ischemic fibrosis (NIF) on cardiac magnetic resonance (CMR) has been linked to poor prognosis, but its association with adverse right ventricular (RV) remodeling is unknown. This study examined a broad cohort of patients with RV dysfunction, so as to identify relationships between NIF and RV remodeling indices, including RV pressure load, volume and wall stress.
Methods And Results: The population comprised patients with RV dysfunction (EF<50%) undergoing CMR and transthoracic echo within a 14 day (5 ± 3) interval.
Objectives: The goal of this study was to determine the prevalence of post-myocardial infarction (MI) left ventricular (LV) thrombus in the current era and to develop an effective algorithm (predicated on echocardiography [echo]) to discern patients warranting further testing for thrombus via delayed enhancement (DE) cardiac magnetic resonance (CMR).
Background: LV thrombus affects post-MI management. DE-CMR provides thrombus tissue characterization and is a well-validated but an impractical screening modality for all patients after an MI.
