Left Atrium: A New Prognostic Marker and Therapeutic Target in Secondary Mitral Regurgitation?

Mitral regurgitation (MR) is one of the most common valvular abnormalities worldwide and can be subdivided into primary and secondary causes. Atrial MR consists of a novel type of secondary MR (SMR), most often observed in patients with AF and heart failure with preserved ejection fraction. The main pathophysiological mechanism of atrial MR is mitral valve annular dilatation.

The Contemporary Role of Speckle Tracking Echocardiography in Cirrhotic Cardiomyopathy.

Cirrhotic cardiomyopathy (CCM) is characterized by elevated cardiac output at rest, an inability to further increase contractility under stress, and diastolic dysfunction. The diagnosis of CCM is crucial as it can lead to complications during liver transplantation. However, its recognition poses challenges with conventional echocardiography techniques.

Resting strain analysis to identify myocardial ischemia in patients with advanced chronic kidney disease.

Background: Chronic kidney disease (CKD) is associated with higher incidence of cardiovascular death. Screening for coronary artery disease in asymptomatic or mildly symptomatic patients is challenging.

Objective: The aim of this study was to investigate the incremental value of resting deformation analysis in predicting positive results for myocardial ischemia during stress transthoracic echocardiography in patients with end-stage CKD.

Speckle tracking echocardiography and β-thalassemia major. A systematic review.

Heart disease is among the primary causes of morbidity and mortality in β-thalassemia major (β-TM). Conventional echocardiography has failed to identify myocardial dysfunction at an early stage among these patients, thus speckle tracking echocardiography (STE) has been lately used. The objectives of this review were to 1) identify all published studies having evaluated myocardial strain among β-TM patients, 2) gather their results, 3) compare their findings and 4) propose recommendations based on these data.

HFA-PEFF score as an independent predictor of 2-year mortality in liver cirrhosis patients.

Background And Aims: Cardiovascular complications of liver cirrhosis include high cardiac output heart failure with reduced afterload and diastolic dysfunction. Heart Failure Association Pre-test assessment, Echocardiography and natriuretic peptide, Functional testing, Final etiology (HFA-PEFF) (values 0-6) is a diagnostic tool for heart failure. It is a cluster of echocardiographic and biochemical parameters.

Left atrial deformation indices in β-thalassemia major patients.

The presence of atrial cardiomyopathy in β-thalassemia major (β-TM) patients complicates their clinical condition. The diagnosis is challenging even with cardiac magnetic resonance (CMR) imaging. Novel echocardiographic techniques are applied to increase the diagnostic yield.

The Fundamental Role of Stress Echo in Evaluating Coronary Artery Disease in Specific Patient Populations.

Stress echocardiography (SE) was initially used for assessing patients with known or suspected coronary heart disease by detecting and evaluating myocardial ischemia and viability. The implementation of SE has gradually been extended to several cardiovascular diseases beyond coronary artery disease, and SE protocols have been modified and adapted for the detection of coronary artery disease (CAD) or other cardiovascular diseases in specific patient populations. This review attempts to summarize current data concerning SE implementation and clinical value in these specific and diverse populations: patients with an intramural course of a coronary artery, known as a myocardial bridge, chronic severe or end-stage hepatic disease, chronic severe or end-stage kidney disease, cardiac allograft vasculopathy, patients scheduled for solid-organ transplantation and other intermediate and high-risk surgery and, finally, patients treated with anticancer drugs or radiotherapy.

Transthoracic ultrasound; seeking the heart in a patient with a large left-sided cirrhotic hydrothorax.

A case of a patient with liver cirrhosis and a large left-sided pleural effusion displacing the heart rightward is presented and the best views to acquire images enabling evaluation of the cardiac function are highlighted. Understanding the modified intrathoracic anatomy in patients with pleural effusions enables quick and focused assessment and can shorten evaluation time while preserving high image quality.

Acute Chest Syndrome in Sickle Cell Disease: Clinical Presentation and Outcomes. The Experience of a Single Thalassemia and Sickle Cell Unit in a University Hospital.

Acute chest syndrome (ACS) is a common cause of death for sickle cell disease patients. This syndrome is defined as: respiratory symptoms, new X-ray findings developed and/or fever; ACS requires prompt treatment to avoid clinical deterioration and death in adults with sickle cell disease. Sixteen episodes of acute chest syndrome were studied in 16 adults with sickle cell disease.

Stroke and presence of patent foramen ovale in sickle cell disease.

Sickle cell disease (SCD) is an inherited monogenic hemoglobinopathy characterized by formation of sickle erythrocytes under conditions of deoxygenation. Sickle erythrocytes can lead to thrombus formation and vaso-occlusive episodes that may result in hemolytic anemia, pain crisis and multiple organ damage. Moreover, SCD is characterized by endothelial damage, increased inflammatory response, platelet activation and aggravation, and activation of both the intrinsic and the extrinsic coagulation pathways.

Twelve-lead and signal-averaged electrocardiographic parameters among beta-thalassemia major patients.

Background: The majority of beta thalassemia major (β-TM) patients suffer from cardiac disease, while a significant proportion of them die suddenly. Twelve-lead and signal-averaged electrocardiography (SAECG) are simple, inexpensive, readily available tools for identifying an unfavorable arrhythmiological substrate by detecting the presence of arrhythmias, conduction abnormalities, and late potentials (LPs) in these patients.

Methods: A total of 47 β-TM patients and 30 healthy controls were submitted to 12-lead and signal-averaged electrocardiography.

Severity of heart failure and health-related quality of life in beta-thalassemia patients: a cross-sectional study.

Cardiovascular complications account for a substantial increase in morbidity and mortality in beta-thalassemia patients. Many patients have structural heart disease, and some of them present with symptomatic heart failure (HF). Quality of life (QOL) of beta-thalassemia patients is lower than that of the general population.
