Endomyocardial biopsy (EMB) has been established in parallel with the development of percutaneous catheter technology for the diagnosis of cardiac diseases. It was developed in the early 1960 s in Japan by Drs. Konno, Sakakibara and Sekiguchi of Tokyo Women's Medical University. EMB is a valuable and useful, but invasive, modality for making a definite diagnosis in diseases such as myocarditis and secondary cardiomyopathies, which are often difficult to diagnose by imaging modality alone. In the field of heart transplantation, the histology of EMB helps monitor rejection to allografts...

A 29-year-old man with a history of seizures, was admitted due to an episode of unconsciousness recovered and hypertension with renal disfunction. The electrocardiogram mimicked a hypertrophic cardiomyopathy, but, by Doppler echocardiography, this was discarded because it suggested endomyocardial fibrosis which was confirmed by cardiac magnetic resonance imaging with late enhancement. Since the episode of unconsciousness, brain imaging studies were performed showing vascular sequelae and microangiopathic lesions...

Endomyocardial fibrosis (EMF) is the most common cardiac abnormality in hyeperosinophilic syndrome (HES), sometimes complicated with mitral valve disease. Mitral valve disease without ventricular manifestation is very rare, however. Case reports link HES to prosthetic valve thrombosis (PVT), but the optimal type of prosthetic valve in HES is not known. Herein is reported the case of a young female HES patient with secondary mitral valve degeneration and severe regurgitation. A mechanical prosthetic valve was implanted six months after she was diagnosed with HES, but despite anticoagulation and antiplatelet therapy she developed PVT three months later...

BACKGROUND: Galectin (Gal)-3 is a β-galactoside-binding lectin and currently intensely studied as a biomarker in heart failure. Gal-3 also exerts proinflammatory effects, at least in extracardiac tissues. Objective of this study was to characterize the relationship of plasma and myocardial Gal-3 levels with cardiac fibrosis and inflammation in patients with nonischemic dilated cardiomyopathy and inflammatory cardiomyopathy (iCMP). METHODS AND RESULTS: Endomyocardial biopsies and blood samples were obtained from patients with newly diagnosed cardiomyopathy and clinical suspicion of myocarditis...

The heart may be affected directly or indirectly by a variety of protozoa and helminths. This involvement may manifest in different ways, but the syndromes resulting from impairment of the myocardium and pericardium are the most frequent. The myocardium may be invaded by parasites that trigger local inflammatory response with subsequent myocarditis or cardiomyopathy, as occurs in Chagas disease, African trypanosomiasis, toxoplasmosis, trichinellosis and infection with free-living amoebae. In amoebiasis and echinococcosis, the pericardium is the structure most frequently involved with consequent pericardial effusion, acute pericarditis, cardiac tamponade or constrictive pericarditis...

BACKGROUND: Matrix metalloproteinase 8 (MMP-8) is the most potent type-I collagen protease. Such collagen mainly constitutes the transient fibrosis in takotsubo cardiomyopathy (TTC) endomyocardial biopsies. High MMP-8 and tissue-inhibitor of matrix metalloproteinase-1 (TIMP-1) levels are implicated in acute coronary syndrome (ACS). We compared MMP-8 and TIMP-1 levels in consecutive TTC and ACS patients, and their association to TTC severity. METHODS AND RESULTS: In 45 acute serum samples of TTC, 2072 ACS and 1000 controls, TIMP-1 differed between ACS 146...

OBJECTIVE: Myocardial fibrosis is associated with alterations in the cross-linking and deposition of collagen type I (CCL and CD, respectively). We aimed to evaluate whether the combination of circulating biomarkers of CCL [the carboxy-terminal telopeptide of collagen type I to matrix metalloproteinase-1 ratio (CITP : MMP-1)] and CD [the carboxy-terminal propeptide of procollagen type I (PICP)] identifies myocardial fibrosis phenotypes with distinct clinical outcome in hypertensive patients with heart failure...

BACKGROUND: Adverse fibrotic remodeling is detrimental to myocardial health and a reliable method for monitoring the development of fibrotic remodeling may be desirable during the follow-up of patients after heart transplantation (HTx). Quantification of diffuse myocardial fibrosis with cardiovascular magnetic resonance (CMR) has been increasingly applied and validated histologically in adult patients with heart disease. However, comparisons of CMR findings with histological fibrosis burden in children are lacking...

BACKGROUND: Severe aortic stenosis (AS), leads to pathological left ventricular remodeling that may worsen with concomitant overweight and obesity (OW/O). METHODS: We aimed to prospectively analyze the impact of OW/O on ventricular remodeling in severe AS, by evaluating the percentage of intraendomyocardial fibrosis (PIEF) and the percentage of infiltrating intraendocardial lipid vacuoles (PIELV) and its relationship to global longitudinal strain (GLS) in patients with OW/O...

Loeffler endomyocardial fibrosis is a rare restrictive cardiomyopathy due to chronic eosinophilic exposure (Loeffler endomyocarditis). Loeffler endomyocarditis is associated with different eosinophilic disorders, including eosinophilic granulomatosis with polyangiitis (EGPA). These images recapitulate all typical findings that can be observed in patients presenting with heart failure attributable to this specific cardiomyopathy associated with EGPA, a systemic medical condition that can be easily detectable just putting together different diagnostic elements...

A 32-year-old pregnant woman, diagnosed with Behçet's disease 6 months earlier, presented with recent mild hemoptysis and exertional dyspnea. Transthoracic echocardiography showed an enlarged dysfunctional right ventricle. A large hypoechoic triangular-shaped mass was seen attached to the inner right ventricular wall, filling the cavity. No change in the size of the mass was noted after anticoagulant administration, and right heart failure progressed. Surgery was performed to remove the mass and repair the tricuspid valve...

Endomyocardial Fibrosis (EMF) is a form of progressive restrictive cardiomyopathy of unclear aetiology prevalent in areas within 15(0) of equator including coastal areas of Kerala a few decades back. It inflicts young adults and carries a poor prognosis due to limited options for treatment. Fortunately, the incidence of cases is now declining due to improvement in health and hygiene standards. Here, we review the aetiology and pathogenesis of EMF and report a case of a young male from Mumbai (non-endemic area) presenting with progressively worsening breathlessness and signs of heart failure unresponsive to conventional medical treatment...

Left ventricular reverse remodeling (LVRR) is reported in dilated cardiomyopathy (DCM) patients (pts). However, numerous definitions of LVRR exist. Measurements of serum markers of fibrosis provide insight into myocardial fibrosis. The relationship between LVRR and fibrosis is poorly understood. From July 2014 until October 2015, we included 63 consecutive DCM pts (48 ± 12.1 years, EF 24.4 ± 7.4%) with completed baseline and 3-month follow-up echocardiograms. LVRR was assessed on the basis of four differing definitions...

Behçet's disease (BD) is a multisystem inflammatory disorder. Intracardiac thrombus (ICT) formation is an uncommon but important complication of BD. Of the cases of Behçet's disease, we selected those with ICT. All patients fulfilled the diagnostic criteria of the International Study Group of Behçet's disease. The ICT in each case was confirmed by ultrasonography, computed tomography and MRI. Clinical features and laboratory parameters were determined. Among our 518 patients with BD, 8 were diagnosed as having intracardiac thrombus (ICT)...

BACKGROUND: Recently, several studies revealed a much higher prevalence of later onset Fabry disease (FD) than previously expected. It suggested that later onset FD might present as an important hidden health issue in certain ethnic or demographic populations in the world. However, the natural history of its phenotype has not been systemically investigated, especially the cardiac involvement. OBJECTIVES: The study analyzed a large-scale newborn screening program for FD to understand the natural course of later onset FD...

BACKGROUND: Few centers for open heart surgery (OHS) are in Sub-Saharan Africa. Lack of OHS results is also noted. By reporting our African experience on OHS, the aim of this study was to fill the gap. METHODS: It is a retrospective study on 2,612 patients who were subject to an OHS between 1978 and 2013. Data were collected from demographical, clinical, investigative studies, surgical and outcomes parameters. RESULTS: There were 1,475 cases of rheumatic heart diseases (RHD), 126 endomyocardial fibrosis (EMF), 741 congenital heart diseases (CHDs) and 270 various affections...

REVIEW
Andrea Beaton, Ana Olga Mocumbi
Endomyocardial fibrosis (EMF) remains an important cause of restrictive cardiomyopathy worldwide. Patients cluster in specific geographic locations and are almost universally living in extreme poverty. Specific etiology remains elusive and is likely multifactorial. Untreated EMF has a very poor prognosis. Medical management can mitigate symptoms for a time but has no curative benefit. Early surgical interventions may improve survival but are not readily available in most EMF-endemic regions. Increased awareness, advocacy, and research are needed to further understand this neglected tropical cardiomyopathy and to improve survival of those affected...

A 48-year-old man from West Africa was evaluated for dyspnea. Echocardiography showed an echolucent mass at the left ventricular apex surrounded by a dense ridge of tissue, suggesting endomyocardial fibrosis (EMF). Doppler echocardiography showed restrictive hemodynamics and intramyocardial coronary blood flow at the hypertrophied apex, suggesting apical hypertrophic cardiomyopathy (ApHCM) with calcified thrombus. Cardiac magnetic resonance imaging showed a thickened myocardium with apical cavity obliteration and endomyocardial calcification, and gadolinium contrast demonstrated marked bright subendocardial and diffuse patchy intramyocardial hyperenhancement in the hypertrophied apical wall segment, confirming coexistence of EMF and ApHCM...
