BACKGROUND: Aortic regurgitation (AR) is a valvular disease that can lead to systolic heart failure. Treatment options besides cardiac surgery are limited and consequently severe AR is associated with higher mortality and morbidity when not operated. In this investigation, we examined the effects of a novel cardiac myosin activator, Omecamtiv-mecarbil (OM), in rats with chronic severe AR. METHODS: AR was created by retrograde puncture of the aortic valve leaflets in 20 adults Wistar rats...

The article focuses on current aspects of epidemiology, clinical picture, and diagnostics of patients with chronic heart failure (CHF) associated with preserved left ventricular (LV) systolic function. Heart failure with preserved LV ejection fraction (HFpEF) is shown to be prevalent in a population that accounts for more than a half of all CHF cases. The group at risk for HFpEF consists primarily of older women with arterial hypertension, type 2 diabetes mellitus, obesity, and atrial fibrillation. The article presents algorithms for diagnosis of HFpEF based on classic and tissue Doppler echocardiography and measurement of natriuretic peptides...

Prenatal diagnosis of a huge coronary artery fistula between the left coronary artery and the right ventricle was made by Doppler echocardiography at 22 weeks of gestation. Progression of the dilated fistula was monitored throughout pregnancy. The size of the fistula increased enormously up to 11 mm. Death occurred at birth. Monitoring of these fetuses is essential as severe complications can occur during pregnancy or at birth.

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...

Renal denervation (RDN) is a potential modality in the treatment of patients with resistant hypertension (RH) and has shown beneficial effect on a variety of cardiovascular surrogate markers. Coronary flow reserve, as assessed by transthoracic Doppler echocardiography (TDE-CFR) is impaired in patients with hypertension and is an independent predictor of cardiac morbidity. However, data on the effect of RDN on TDE-CFR are scarce. The main objective of this study was to assess the effect of RDN on TDE-CFR. Twenty-six consecutive patients with RH (9 female and 17 male; mean age 62 ± 8 years; mean number of antihypertensive drugs 4·2 ± 1·6) underwent bilateral RDN...

OBJECTIVE: Intraoperative Doppler-determined renal resistive index (RRI) is a promising early acute kidney injury (AKI) biomarker. As RRI continues to be studied, its clinical usefulness and robustness in research settings will be linked to the ease, efficiency, and precision with which it can be interpreted. Therefore, the authors assessed the usefulness of computer vision technology as an approach to developing an automated RRI-estimating algorithm with equivalent reliability and reproducibility to human experts...

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...

Mark K Friedberg
The impact of one ventricle on the adjacent ventricle plays a key role in cardiac function. Ventricular-ventricular interactions are based on the arrangement in-series of the circulation and common pericardium, interventricular septum, and myocardial tracts. Imaging, in particular echocardiography, plays a central role in characterizing these interactions through geometric indices, septal configuration and motion, Doppler flow, timing of events in the ventricles and alterations in strain, remodeling, and diastolic filling with altered loading of the contralateral ventricle...

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...
