BACKGROUND: The risk of stroke and thromboembolism in atrial fibrillation is established. There are clear guidelines in anticoagulation management of patient's with atrial fibrillation, however, the evidence surrounding the risk of thromboembolism in patients with atrial flutter is not as clear. We hypothesized that atrial flutter would have indicators of less risk for thromboembolism compared with atrial fibrillation on transesophageal echocardiography (TEE); thereby possibly leading to a lower stroke risk...

BACKGROUND: Recent American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI) guidelines for echocardiographic evaluation of left ventricular (LV) diastolic function provide a practical, simplified diagnostic algorithm for estimating LV filling pressure. The aim of this study was to test the accuracy of this algorithm against invasively measured pressures and compare it with the accuracy of the previous 2009 guidelines in the same patient cohort...

In hypertrophic cardiomyopathy (HCM) patients with symptoms caused by left ventricular outflow tract obstruction (LVOTO), treatment options include negative inotropic drugs, myectomy, septal alcohol ablation and AV sequential pacing with or without an implantable cardioverter defibrillator (ICD). Pacing is rarely used in spite of its relative simplicity and promising results. In this review the current evidence of AV sequential pacing from observational, randomised studies and long and very long-term follow-up studies is given and put in the context of present guidelines recommendations...

Takotsubo syndrome (TTS) was first described in 1991 as a rare, spontaneous and completely reversible left ventricular regional systolic dysfunction. Today the incidence of TTS is estimated at 2% in patients with an initial diagnosis of acute coronary syndrome (ACS). Notably, the incidence can be as high as 5.9 to 7.5% in female patients. TTS occurs predominantly in postmenopausal women, but both sexes may be affected, at any age. Acute chest pain or dyspnoea is a characteristic symptom of TTS, but initial presentation can also include more severe disease manifestation such as acute heart failure with pulmonary oedema or haemodynamic instability, especially in an in-hospital setting...

REVIEW
M Cameli, E Incampo, S Mondillo
In chronic mitral regurgitation (MR) left atrium is one of the first cardiac structures that is involved in remodeling and ultrastructural changes for a progressive volume overload. Severe left atrial (LA) dilation on echocardiography and new onset of atrial fibrillation in asymptomatic patients with preserved Left Ventricular (LV) function, appeared as a Class IIb recommendation for consideration for surgical mitral valve repair in the actual guidelines. However, before atrial dilatation and dysfunction, several ultrastructural changes appear in the atrial muscle tissue that are difficult to identify with the standard echocardiography...

Aims: In degenerative mitral regurgitation (DMR), lack of mortality scores predicting death favours misperception of individual patients' risk and inappropriate decision-making. Methods and results: The Mitral Regurgitation International Database (MIDA) registries include 3666 patients (age 66 ± 14 years; 70% males; follow-up 7.8 ± 5.0 years) with pure, isolated, DMR consecutively diagnosed by echocardiography at tertiary (European/North/South-American) centres...

BACKGROUND: Echocardiography has been proposed as a method to screen children for rheumatic heart disease. The World Heart Federation has established guidelines for echocardiographic screening. In this study, we describe a rapid echocardiogram screening protocol according to the World Heart Federation guidelines in Samoa, endemic for rheumatic heart disease. METHODS: We performed echocardiogram screening in schoolchildren in Samoa between 2013 and 2015. A brief screening echocardiogram was performed on all students...

PURPOSE: Mitral regurgitation (MR) grading by two-dimensional transthoracic echocardiography is challenging, but important to determine the best treatment strategy in patients with MR. Current guidelines advocate an integrative approach, although no recommendation is provided on how to do so. An easy-to-use index will be helpful for standardized and reproducible MR grading. METHODS: Eleven echocardiographic parameters were retrospectively evaluated in 145 patients with moderate or severe MR...

BACKGROUND: Acute severe mitral regurgitation (MR) is a serious medical condition. Whilst clear guidelines exist regarding the management of chronic MR, acute severe MR is usually treated on an individual basis. Currently, few data exist regarding acute MR in the era of primary coronary interventions (PCI). The present study included patients admitted to the Department of Cardiology during recent years with acute severe MR of different etiologies, and an analysis of these data in the light of previous investigations...

The effect of percutaneous mitral valve repair using the MitraClip system on tricuspid regurgitation (TR) has not been well investigated. We retrospectively analyzed 102 consecutive patients who underwent the successful MitraClip procedure, and who also had a preprocedural and 1-year follow-up transthoracic echocardiography. TR severity was graded by standard guideline-recommended criteria. At 1 year after the MitraClip procedure, the degree of TR regressed (at least 1 grade) in 23% of the patients, was unchanged in 62% of the patients, and progressed in 16% of the patients...

REVIEW
Steven M Hollenberg
The prevalence of valvular heart disease (VHD) in the United States was estimated to be approximately 2.5% in the 1990s. The prevalence currently is thought to be increasing because of more accurate diagnostic methods and aging of the population. Mitral regurgitation (MR) is the most common valve defect, followed by aortic stenosis (AS) and aortic regurgitation (AR). Degenerative disease is the most common etiology of MR, AS, and AR, though these forms of VHD also can be caused by congenital valve defects, systemic inflammatory diseases, endocarditis, and many other conditions...

An 86-year-old man underwent cataract surgery on the left eye, but suddenly he lost his vision three days after surgery. Topical treatments for panophthalmitis were started according to international guidelines. Later, a broad-range polymerase chain reaction showed Enterococcus faecalis in corpus vitreum, and IV antiobiotic treatment was initiated. To exclude endocarditis an echocardiography was performed, and this showed mitral regurgitation with a small mobile vegetation. Uncertainty concerning a possible causality between panophthalmitis and mitral valve endocarditis remains...

The global impact of the spectrum of valve diseases is a crucial, fast-growing, and underrecognized health problem. The most prevalent valve diseases, requiring surgical intervention, are represented by calcific and degenerative processes occurring in heart valves, in particular, aortic and mitral valve. Due to the increasing elderly population, these pathologies will gain weight in the global health burden. The two most common valve diseases are aortic valve stenosis (AVS) and mitral valve regurgitation (MR)...

Grading of chronic aortic regurgitation (AR) and mitral regurgitation (MR) by cardiovascular magnetic resonance (CMR) is currently based on thresholds, which are neither modality nor quantification method specific. Accordingly, this study sought to identify CMR-specific and quantification method-specific thresholds for regurgitant volumes (RVols), RVol indexes, and regurgitant fractions (RFs), which denote severe chronic AR or MR with an indication for surgery. The study comprised patients with moderate and severe chronic AR (n = 38) and MR (n = 40)...

PURPOSE OF REVIEW: Ischemic and non-ischemic injury to the heart causes deleterious changes in ventricular size, shape, and function. This adverse remodeling is mediated by neurohormonal and hemodynamic alterations and is reflected in non-invasive measures of left ventricular ejection fraction (LVEF), left ventricular end-systolic volume (LVESV), and left ventricular end-diastolic volume (LVEDV). These measures are closely linked to cardiovascular outcomes and have become key surrogate endpoints for evaluating the therapeutic efficacy of contemporary treatments for heart failure with reduced ejection fraction (HFrEF)...
