BACKGROUND: Infective endocarditis (IE) is uncommon in childhood. Its associated epidemiological characteristics in patients with congenital heart disease (CHD) remain unclear. METHODS: The study population included children born in Taiwan during the years 1997 to 2005 who were diagnosed as having CHD before 3years of age. All children were followed up until the end year of 2010, the diagnosis of infective endocarditis, or death. The demographic characteristics of patients with and without IE, the invasive procedures performed during 6months before the index date, the prophylactic antibiotics related to dental procedures, and in-hospital mortality were collected...

BACKGROUND: Valvular heart disease is highly prevalent in industrialized countries. Chronic use of anorexigens, amphetamine or ergot derivatives targeting the serotonin system has been associated with valvular heart disease. PURPOSE AND EXPERIMENTAL APPROACH: Here, we investigated the contribution of serotonin receptors in a mouse model of valve degeneration induced by nordexfenfluramine, the main metabolite of the anorexigens dexfenfluramine and benfluorex. KEY RESULTS: Chronically activated 5-HT2B receptors by nordexfenfluramine in mice mimicked early steps of mitral valve remodelling attested by increased valve thickness, and cell density in a thick extracellular matrix...

Myxomatous mitral valve disease (MMVD) is functionally and histologically identical to mitral valve prolapse (MVP) in humans. Currently, there are no medical treatments that can delay the progression of this valvular disease or associated cardiac remodelling. Therefore, there is a need to understand the molecular pathology associated with MMVD and MVP better, and thus identify potential therapeutic targets. Circulating exosomes contain small RNA, including miRNA, which reflect cell physiology and pathology...

Functional tricuspid valve (TV) regurgitation secondary to left heart disease (e.g. mitral insufficiency and stenosis) is observed in 75% of the patients with TV regurgitation and is thus the most common etiology; therefore, the majority of patients who require TV surgery, undergo concomitant mitral and/or aortic valve surgery. Uncorrected moderate and severe TV regurgitation may persist or even worsen after mitral valve surgery, leading to progressive heart failure and death. Patients with moderate to severe TV regurgitation show a 3-year survival rate of 40%...

OBJECTIVE: For chronic heart failure (CHF), more emphasis has been placed on evaluation of systolic as opposed to diastolic function. Within the study of diastology, measurements of left ventricular (LV) longitudinal myocardial relaxation have the most validation. Anterior wall radial myocardial tissue relaxation velocities along with mitral valve inflow (MVI) patterns are applicable diastolic parameters in the differentiation between moderate and severe disease in the ischemic rat model of CHF...

Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a nonmalignant disease of unknown etiology. It may present as bilateral, massive, painless cervical lymphadenopathy; however, one third of the cases have extranodal involvement. Extranodal sites include soft tissue, skin, upper respiratory and gastrointestinal tracts, and central nervous system, with head and neck being the most common. Here we report a rare case of intracardiac RDD in a 46-year-old, African-American female who presented with worsening shortness of breath and fatigue for 7 weeks...

OBJECTIVES: The association of transaortic flow rate (FR) with outcomes was tested in 1,661 patients with aortic valve stenosis (AS) in the SEAS (Simvastatin and Ezetimibe in Aortic Stenosis) study. BACKGROUND: Low transaortic flow may complicate grading of AS. However, the association of lower transaortic FR with adverse outcomes has not been reported. METHODS: Transaortic FR was calculated from Doppler-derived stroke volume in milliliters divided by systolic ejection time in seconds and considered low if <200 ml/s...

We herein report the case of a 68-year-old woman with a skin and soft tissue infection at her extremities. The blood culture results were positive for Streptococcus pyogenes, and we started treatment using ampicillin and clindamycin, although subsequent auscultation revealed a new-onset heart murmur. We therefore suspected rheumatic heart disease and infective endocarditis. The case met both the Jones criteria and the modified Duke criteria. Transesophageal echocardiography revealed vegetation on the aortic valve, although the pathological findings were also compatible with both rheumatic heart disease and infective endocarditis...

Tricuspid valve regurgitation is frequently found as a result of right ventricular remodeling due to advanced left heart diseases. Drug treatment is limited to diuretics and the cardiac or pulmonary comorbidities. Due to the high risk only a small percentage of patients are amenable to surgical treatment of tricuspid regurgitation in those who undergo left-sided surgery for other reasons. Catheter-based procedures are an attractive treatment alternative, particularly since the strong prognostic impact of tricuspid regurgitation suggests an unmet need of treatment, independent of the underlying heart disease...

This case study aim to evaluate the response of steroid treatment for autoimmune endocarditis. Valvular heart disease is relatively rising in both congenital and acquired cases, but the autoimmune endocarditis remains rare. In this case, a 34 year old woman with clinical manifestation resembling systemic lupus erythematosus (SLE) is diagnosed with Libman-sacks Endocarditis. After six months of steroid treatment, her clinical manifestations and heart structure improved.

BACKGROUND: Pre-existing chronic kidney disease (CKD) portends adverse outcomes following heart valve surgery. However, only limited and conflicting evidence is available on the impact of CKD on outcomes following transcatheter aortic valve replacement (TAVR). The objective of this review was to evaluate the effect of pre-existing CKD on TAVR outcomes. METHODS: We performed a systematic electronic search using the PRISMA statement to identify all randomized controlled trials and observational studies investigating the effect of pre-existing CKD on outcomes following TAVR...

Heart valve disease is a major health burden, treated by either valve repair or valve replacement, depending on the affected valve. Nearly 300,000 valve replacements are performed worldwide per year. Valve replacement is lifesaving, but not without complications. The in situ tissue-engineered heart valve is a promising alternative to current treatments, but the translation of this novel technology to the clinic still faces several challenges. These challenges originate from the variety encountered in the patient population, the conversion of an implant into a living tissue, the highly mechanical nature of the heart valve, the complex homeostatic tissue that has to be reached at the end stage of the regenerating heart valve, and all the biomaterial properties that can be controlled to obtain this tissue...

BACKGROUND: Inconsistencies between gradients and aortic valve area are frequent in the echocardiographic evaluation of aortic stenosis (AS). Assessing AS severity is essential for the correct management of the disease. The aim of this study was to evaluate whether ejection dynamics, particularly acceleration time (AT) and the ratio of AT to ejection time (ET), could be diagnostic parameters in patients with AS. METHODS: Patients with AS (aortic peak velocity > 2 m/sec) were prospectively enrolled...

Lucy M Safi, Sarah V Tsiaras
Valvular heart disease in women of childbearing age poses an increased risk of adverse maternal and fetal outcomes, and management in pregnancy can be challenging. Ideally, patients with suspected valvular disease should have preconception counseling by a multidisciplinary team including cardiologists with expertise in pregnancy and a maternal-fetal medicine specialist. Preconception planning should include a cardiac assessment of maternal risk, determination of frequency of surveillance, and a cardiovascular management plan during delivery...

OBJECTIVES: Rheumatic mitral stenosis (MS) is a progressive disease, and risk of death may persist despite relief of the obstruction. Net atrioventricular compliance (Cn) modulates the overall haemodynamic burden of the MS and may be useful in predicting cardiovascular death after percutaneous mitral valvuloplasty (PMV). METHODS: A total of 427 patients (mean age 50±16 years, 84% female) with severe MS undergoing PMV were enrolled. Doppler-derived Cn was estimated at baseline using a previously validated equation...

REVIEW
Wei Yao Lim, Guy Lloyd, Sanjeev Bhattacharyya
Valve thrombosis can occur in mechanical prosthetic valves and is increasingly recognised in transcatheter and surgically implanted bioprosthetic valves. The risk of thrombosis of mechanical valves is higher in the mitral position compared with aortic position and in older generation valves (ball and cage valves). There is a wide spectrum of presentation from the asymptomatic patient to those with embolic complications or cardiogenic shock. A combination of transthoracic and transesophageal echocardiography is required to assess the haemodynamic effect of thrombosis (valve gradients and area), leaflet motion and thrombus size...

Infective endocarditis is a rare disease associated with high morbidity and mortality. As a result, early diagnosis and prompt antibiotic treatment with or without surgical intervention is crucial in the management of such condition.We report a case of missed infective endocarditis of the aortic valve. The patient underwent mechanical aortic valve replacement, with the native valve being sent for histopathological examination. On re-admission 16 months later, he presented with syncope, shortness of breathing and complete heart block...
