The natural history of mitral regurgitation (MR) results in significant morbidity and mortality. Innovations in non-invasive imaging have provided new insights into the pathophysiology and quantification of MR, in addition to early detection of left ventricular (LV) dysfunction and prognostic assessment in asymptomatic patients. Transthoracic (TTE) and transesophageal (TOE) echocardiography are the mainstay for diagnosis, assessment and serial surveillance. However, the advance from 2D to 3D imaging leads to improved assessment and characterization of mitral valve (MV) disease...

Cardiac patients of all ages were managed in the past by internists who specialized in cardiology. During the past 50 years, the medical field has witnessed great strides in the management of congenital heart disease, and thus pediatric cardiology has become a subspecialty in many countries. This review article focuses on the advances in fetal cardiac interventions (FCI) since its inception by our group in 1975. Three major modes of FCI have evolved during the past 42 years: pharmacologic, closed FCI, and open FCI...

BACKGROUND: Heart involvement is the most important prognostic determinant in AL amyloidosis patients. Echocardiography is a cornerstone for the diagnosis and provides important prognostic information. METHODS AND RESULTS: We studied 754 patients with AL amyloidosis who underwent echocardiographic assessment at the Mayo Clinic, including a Doppler-derived measurement of stroke volume (SV) within 30 days of their diagnosis to explore the prognostic role of echocardiographic variables in the context of a well-established soluble cardiac biomarker staging system...

Cancer therapies have resulted in increased survivorship in oncological patients. However, the benefits have been marred by the development of premature cardiovascular disease. The current definition outlines measurement of ejection fraction as a mean to diagnose cancer therapeutic-related cardiac dysfunction (CTRCD); however, up to 58% of the patients do not regain their cardiac function after the CTRCD diagnosis, despite therapeutic interventions. Therefore, there has been a growing interest in the markers for early myocardial changes (ie, changes with normal left ventricular ejection fraction [LVEF]) that may predict the development of subsequent left ventricular ejection fraction reduction or progression to heart failure...

Left ventricular diastolic dysfunction (LVDD) frequently occurs in chronic kidney disease (CKD) and is associated with heart failure and higher mortality. LVDD is observed in patients with early stages of CKD and is associated with cardiovascular events, in patients undergoing incident hemodialysis in the absence of systolic function. The pathogenesis of CKD includes abnormal ventricular filling in diastole and a higher LV filling pressure (LVFP) because of LV hypertrophy (LVH), in addition to myocardial interstitial fibrosis...

Rheumatic fever (RF) is an autoimmune disease associated with group A β-hemolytic streptococcal infection, in the course of which the patient develops carditis, arthritis, chorea, subcutaneous nodules and erythema marginatum. Rheumatic fever diagnosis is based on the Jones criteria, developed in 1944, then revised twice by the American Heart Association (AHA), in 1992 and recently in 2015. The last revision of the Jones criteria consists mainly in the supplementation of the major criteria with echocardiographic examination, the introduction of a concept of subclinical carditis and the isolation of low, medium and high risk populations among the patients...

In the neonatal and pediatric intensive care setting, bedside cardiac ultrasound is often used to assess ventricular dimensions and function. Depending upon the underlying disease process, it is necessary to be able to evaluate the systolic and diastolic function of left and or right ventricles. The systolic function of left ventricle is mostly assessed qualitatively on visual inspection "eye-balling" and quantitatively by measuring circumferential fraction shortening or calculating the ejection fraction by Simpson's planimetry...

BACKGROUND: Left ventricular (LV) diastolic dysfunction (DD) is a frequent finding in obesity and may predispose to the development of heart failure (HF). However, no data are available on the prevalence of DD after the introduction of the 2016 Recommendations of the American Society of Echocardiography and the European Association of Cardiovascular Imaging. METHODS AND RESULTS: To assess the impact of the new Recommendations on the prevalence of DD and on their clinical and echocardiographic correlates in obesity, a prospective study was performed in 588 subjects with an ejection fraction (EF) ≥50% and no history of HF either obese (n = 402; mean age: 47 ± 12 years; women 71%; body mass index [BMI]: 44 ± 8 kg/m2 ), overweight (n = 86; BMI: 28 ± 1 kg/m2 ), or with a normal weight (n = 100; BMI: 22 ± 2 kg/m2 )...
