This study reports pathological and molecular features in 41 cases of feline restrictive cardiomyopathy (RCM). Grossly, there were patchy or diffuse areas of endocardial thickening affecting the left ventricle. The more common patchy endocardial lesions occurred as large trabecular or irregular broad bands of fibrous tissue bridging the left ventricular free wall and ventricular septum. Microscopically, regardless of the gross pattern, the thickened endocardium contained various numbers of stellate, spindle-shaped or elongated mesenchymal cells surrounded by fibrous connective tissue...

Eosinophilic endomyocarditis is extremely rare in paediatrics. This case report aims to present the sequential changes from thrombotic to fibrotic stages of the cardiac involvement in a child with hypereosinophilic syndrome. Endomyocardial fibrosis progressively aggravated the severity of the mitral regurgitation. Bioprosthetic valve replacement was finally performed without recurrence of cardiac complications despite a late relapse of the underlying disease.

Hypereosinophilic syndrome (HES) describes a disorder characterized by persistent peripheral blood eosinophilia with evidence of multiple target organs damage caused by eosinophilia. HES most commonly involves the heart, and cardiac involvement typically presents in the form of endomyocarditis or myocarditis with apical mural thrombus formation.We present a case with atypical cardiac presentation with massive intracardiac fragile thrombi, causing peripheral emboli and strokes.HES can present as floating thrombi with thin attachment to the left ventricle, and clinicians should also be vigilant of thromboembolic complications and initiate early therapy to prevent or reduce the potential complications of HES...

Background Eosinophilic endomyocarditis (EEM) is a rare diagnosis that is extremely uncommon in newborns. This case report aimed to present a case of neonatal mortality from acute cardiac failure due to EEM. Case Our report presents a term male neonate with minor complications in the immediate postnatal course, who was discharged at 48 hours of life, but who developed unexpected respiratory distress, followed by cardiac arrest and death at 3 days of life. One day after discharge, the infant developed respiratory distress and cool skin, and then developed cardiac arrest at the pediatrician's office, undergoing resuscitation with intravenous fluid, cardiopulmonary resuscitation, epinephrine, atropine, and failed intubation...

Right ventricular endomyocardial biopsy specimens from a 13-year-old boy with hypereosinophilia were studied by light and electron microscopy using the EG2 monoclonal antibody, which recognizes a common epitope of eosinophil cationic protein and eosinophil protein-X. Although the endocardial layer was of normal thickness, many eosinophils, mononuclear cells, and free eosinophil granules were observed in the endocardium and in the vicinity of degenerated myocardial cells. Under electron microscopy, many of the specific granules in and out of eosinophils had lost their crystalloid internae and displayed reversed density, and there were many degranulated eosinophils with reduced number of granules...

Loeffler endocarditis is a fibrous restrictive cardiomyopathy thought to be caused by persistent eosinophilia. It is difficult to diagnose, and the prognosis is often poor if the underlying eosinophilia is not promptly recognized and treated. We describe the case of a middle-aged woman treated for hypertrophic cardiomyopathy first detected during a routine check-up at age 35years but whose symptoms gradually progressed over the next 14years. Right ventricular biopsy showed extensive fibrosis of the endocardial tissue, and right heart catheterization revealed right heart failure and a low cardiac output state...

UNLABELLED: Aim of the study was to elucidate nosological nature of "idiopathic" arrhythmias by means of right ventricular endomyocardial biopsy (EMB) and to assess effect of etiotropic and pathogenetic treatment. MATERIAL AND METHODS: We included into this study 19 patients (mean age 42.6 +/-11.3 years, 9 women) with atrial fibrillation (AF, n = 16), supraventricular (n = 10) and ventricular (n = 4) extrasystoles (SVE and VE), supraventricular (n = 2) and ventricular (n = 1) tachycardia (SVT and VT), left bundle branch block (LBBB, n = 2), atrioventricular block (n = 2) without structural changes of the heart...

Cardiac involvement in Churg-Strauss syndrome (CSS) is a major cause of mortality. Here we report a case of a 75-year-old woman with eosinophilic endomyocarditis due to CSS. An electrocardiogram showed intraventricular conduction delay, and echocardiography showed an impaired relaxation pattern and biventricular apical thickening. Magnetic resonance imaging revealed subendocardial delayed enhancement with biventricular apical thrombi. Endomyocardial biopsy showed perivascular eosinophilic infiltration. Despite resolution of the hypereosinophilia after steroid therapy, her left ventricular (LV) diastolic function worsened into a restrictive pattern and she died with a ventricular escape rhythm on her 14th day in the hospital...

We report a case of a 43-year-old woman, who presented with thoracic interscapular pain at a peripheral hospital. In addition, the patient reported retrosternal pain, which had occurred only hours before-after an upsetting telephone call. The CT imaging ruled out an aortic dissection but revealed a huge sinus valsalva aneurysm (SVA) while the laboratory parameters showed slightly elevated troponin T value. Echocardiography showed an akinesia of the midventricular and apical left ventricular wall, accompanied by normal basal contractility...

Hypereosinophilic syndromes are rare diseases; however, cardiac involvement is frequently seen. When diagnosed promptly, the prognosis is relatively good; however, a final diagnosis is made by ruling out many conditions leading to secondary eosinophilia. We present a case of Loeffler's endomyocarditis primarily misdiagnosed as an acute coronary syndrome, complicated by low output heart failure and cardiac arrest. After hypereosinophilic syndrome was confirmed and treatment with prednisone initiated, the patient responded well to therapy, and her further recovery was complete and uneventful...

BACKGROUND: The pathway from viral myocarditis to end-stage heart failure is commonly accepted, but diagnosis of virus-mediated myocardial injury remains challenging. Virus persistency in the myocardium may accelerate ventricular failure; thus, a precise diagnosis of virus persistency may prevent the development of end-stage heart failure. METHODS: We performed a systematic investigation on the sampling error of viral diagnostics in heart transplant recipients: Transmural samples from 5 regions of the explanted hearts from recipients during heart transplantation were amplified using entero-, adeno-, and herpesvirus sequences and histologic examinations performed...

Cardiac involvement is the main cause of morbidity and mortality in hypereosinophilic syndrome. In a patient with hypereosinophilia and a normal echocardiography, cardiac magnetic resonance imaging (CMR) helped confirm early cardiac involvement by demonstrating a typical pattern of left ventricular subendocardial and papillary muscle involvement. The use of CMR facilitated prompt institution of aggressive therapy and was useful in monitoring response to treatment.

Eosinophilic endomyocarditis is a manifestation of hypereosinophilic syndrome, characterized by prolonged (>6 months), unexplained peripheral blood eosinophilia (>1,500 cells/mm(3)) with end-organ damage in unknown causes. We report a case of a 42-year-old patient who developed eosinophilic endomyocarditis following upper respiratory tract symptoms for 2 months. Additionally, endomyocarditis was combined with massive pleural effusion and pericardial effusion, which have not been reported in Korea.
