A 43-year-old female patient with mitral valve stenosis and hypereosinophilia on admission received mechanical mitral valve replacement. During the 2 years after the first surgery, the patient underwent two mitral valve revision operations for repeated prosthetic mitral valve thrombosis. During the 2-year period, the patient's absolute eosinophil count was found elevated repeatedly. Finally, fluke antibody detection revealed fluke infection and, after praziquantel treatment, a normal level of absolute eosinophil count has been maintained and recurrent thrombosis has not occurred for 18 months...

INTRODUCTION AND OBJECTIVES: We investigated the anatomical localization, biomechanical properties, and molecular phenotype of myocardial collagen tissue in 40 patients with severe aortic stenosis with preserved ejection fraction and symptoms of heart failure. METHODS: Two transmural biopsies were taken from the left ventricular free wall. Mysial and nonmysial regions of the collagen network were analyzed. Myocardial collagen volume fraction (CVF) was measured by picrosirius red staining...

BACKGROUND: Infective endocarditis rarely causes mitral valve stenosis. When present, it has the potential to cause severe hemodynamic decompensation and death. There are only 15 reported cases in the literature of mitral prosthetic valve bacterial endocarditis causing stenosis by obstruction. This case is even more unusual due to the mechanism by which functional mitral stenosis occurred. CASE PRESENTATION: We report a case of a 23-year-old white woman with a history of intravenous drug abuse who presented with acute heart failure...

REVIEW
W Randolph Chitwood
Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morrow developed a trans-aortic approach to resect a large part of the ventricular septum, enlarging the outflow tract. The Morrow operation has remained the gold standard for surgically treating this pathology...

We present a rather unusual cause for syncope associated with atrial tachycardia. A man aged 39 years presented with an episode of syncope and narrow complex tachycardia. Further investigations, including transoesophageal echocardiography, identified cor triatriatum sinistrum (CTS), a rare congenital abnormality characterised by the atrium being divided by a fibrous membrane. Although it is rare, there has been an increase in diagnosis due to developments in diagnostic imaging techniques. Symptoms are related to the size of fenestrations within the fibrous membrane...

Numerical abnormalities of mitral leaflets is a special entity in congenital mitral malformations. Previously reported cases of uni-leaflet mitral valve were primarily related to absence or dysplasia of certain leaflets. We present a case here with mitral leaflets that were not divided into anterior and posterior as usual, but developed as an integral structure instead, which is different from previously documented cases of uni-leaflet mitral valves. Real time three-dimensional echocardiography (RT3DE) provides a visual presentation of the abnormal mitral structure which was confirmed by surgical operation...

Left atrial (LA) calcification is mostly observed in patients with rheumatic mitral valve (MV) diseases who underwent surgical treatment. We report a case of LA calcification in a 69-year-old woman presented with dyspnea and cyanosis. Admission electrocardiogram showed atrial fibrillation and biventricular hypertrophy. Her chest roentgenogram revealed cardiomegaly and a curvilinear whitish shadow in the area of LA. Transthoracic echocardiography revealed severe mitral stenosis and massive LA thrombosis. The patient underwent an emergent surgery, during which the whitish line on chest roentgenogram proved to be a calcified LA inner wall...

BACKGROUND: The diagnosis of Immunoglobulin G4 (IgG4)-related disease (IgG4-RD), in general, depends on serum IgG4 concentrations and histopathological findings; therefore, diagnosis of IgG4-RD in cardiovascular organs/tissues is often difficult owing to the risk of tissue sampling. METHODS: Prevalence of IgG4-positive lymphoplasmacytic infiltration in 103 consecutive cardiovascular surgical samples from 98 patients with various cardiovascular diseases was analyzed immunohistochemically...

Some cryptogenic strokes are caused by undetected paroxysmal atrial fibrillation (AF) and could benefit from oral anticoagulation. In this study, we searched for echocardiographic parameters associated with first diagnosed AF, to form a scoring system for the identification of patients with AF. We examined 571 patients with ischemic stroke (72.7 ± 13.5 years, 50.6% women), subdivided into 4 groups: documented cause without AF, first diagnosed AF, known paroxysmal AF, and permanent AF. All patients underwent transthoracic echocardiography, brain computed tomography scan, carotid/vertebral ultrasound, and continuous electrocardiographic monitoring...

PURPOSE: The aim of this study was to evaluate the proportion of suspected heart failure patients with significant valvular heart disease. Early diagnosis of valve disease is essential as delay can limit treatment and negatively affect prognosis for undiagnosed patients. The prevalence of unsuspected valve disease in the community is uncertain. PARTICIPANTS: We prospectively evaluated 79 043 patients, between 2001 and 2011, who were referred to a community open access echocardiography service for suspected heart failure...

REVIEW
Jeroen J Bax, Victoria Delgado
Although echocardiography remains the mainstay imaging technique for the evaluation of patients with valvular heart disease (VHD), innovations in noninvasive imaging in the past few years have provided new insights into the pathophysiology and quantification of VHD, early detection of left ventricular (LV) dysfunction, and advanced prognostic assessment. The severity grading of valve dysfunction has been refined with the use of Doppler echocardiography, cardiac magnetic resonance (CMR), and CT imaging. LV ejection fraction remains an important criterion when deciding whether patients should be referred for surgery...

Autoimmune inflammatory reactions leading to rheumatic fever (RF) and rheumatic heart disease (RHD) result from untreated Streptococcus pyogenes throat infections in individuals who exhibit genetic susceptibility. Immune effector mechanisms have been described that lead to heart tissue damage culminating in mitral and aortic valve dysfunctions. In myxomatous valve degeneration (MXD), the mitral valve is also damaged due to non-inflammatory mechanisms. Both diseases are characterized by structural valve disarray and a previous proteomic analysis of them has disclosed a distinct profile of matrix/structural proteins differentially expressed...
