1. GLA Gene Mutation in Hypertrophic Cardiomyopathy with a New Variant Description: Is it Fabry's Disease?
Resumo Fundamento: A doença de Fabry (DF) é uma doença de armazenamento lisossômico ligada ao cromossomo X, devido a mutações no gene da alfa galactosidase A (GLA), levando a deficiência enzimática de alfa-galactosidase (α-Gal A) e acúmulo de globotriaosilceramida (Gb3) e globotriaosilsulfingosina (liso-Gb3), causando disfunção de múltiplos ó

2. Human pulmonary dirofilariasis with secondary myocarditis
Abstract Dirofilariasis is a little-known zoonosis, with dogs and cats as definitive hosts. It is caused by nematodes and transmitted by mosquito bites. We report the case of a 67-year-old man with a consumptive syndrome with two subpleural pulmonary opacities. A transthoracic lung biopsy revealed a Dirofilaria worm. Myocardial nuclear magnetic resonance (NM

3. Development of a Multifunctional Needle for Percutaneous Heart Biopsy and Cell Therapy. A Technical Note
Abstract Validation of transendocardial injection as a method for delivering therapeutic agents to the diseased heart is increasing. Puncture heart biopsies should re-emerge as a possible alternative method to allow access to the myocardium and implantable biomaterial for cell therapy. Therefore, this work aims to present a percutaneous puncture device for b

4. HLA-DR3 antigen in the resistance to idiopathic dilated cardiomyopathy
Idiopathic dilated cardiomyopathy (IDC) has been hypothesized as a multifactorial disorder initiated by an environment trigger in individuals with predisposing human leukocyte antigen (HLA) alleles. Published data on the association between HLA-DR3 antigen and IDC risk are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis

5. Myocardic fibrosis associated with chronic mitral insuficiency. A magnetic resonance study / Fibrose miocárdica associada à insuficiência mitral crônica: estudo pela ressonância magnética
Introdução: A história natural da insuficiência mitral associa-se a décadas de remodelação ventricular esquerda com fibrose intersticial. A fronteira entre o processo adaptativo e a miocardiopatia dilatada demanda avaliação clínico-histológica. Atualmente, sabe-se que o melhor método empregado para quantificar as alterações decorrentes do remod

6. Collagen content, but not the ratios of collagen type III/I mRNAs, differs among hypertensive, alcoholic, and idiopathic dilated cardiomyopathy
Cardiac interstitial fibrosis may contribute to ventricular dysfunction and the prognosis of patients with dilated cardiomyopathy. The objective of the present study was to determine if total myocardial collagen content and collagen type III/I (III/I ratio) mRNAs differ in hypertensive, alcoholic, and idiopathic dilated cardiomyopathy subjects. Echocardiogra

7. Disfunção ventricular no pós-operatório da intervenção cirúrgica para correção dos defeitos congênitos da Tetralogia de Fallot: estudo de correção clínica e anatomopatológica / Ventricular dysfunction after the surgical repair of Fallot´s tetralogy: a clinical and anatomopathological study
It was investigate prospectively the histopathological myocardial remodeling in children submitted to surgical repair of Fallots tetralogy, in order to detect possible factors associated to postoperative (PO) echocardiographic findings of systolic or diastolic ventricular dysfunction. Patients and Methods: 23 consecutive Fallot patients (14 males), aged 12 t

8. O papel do acúmulo do colágeno miocárdico intersticial na sobrevida dos pacientes com miocardiopatia dilatada idiopática e chagásica / The role of myocardial interstitial collagen in the survival rate of patients with idiopathic and chagasic cardiomyopathy.
As miocardiopatias dilatadas representam 87% das miocardiopatias e apresentam evolução adversa com grande morbi-mortalidade. Vários marcadores de prognóstico são bem definidos, entretanto, um marcador estrutural se faz necessário. Estudamos através da realização da biópsia endomiocárdica e exame ecocardiográfico, 9 indivíduos sem doença estrutu

9. Apical aneurysm and left ventricular hypertrophy
A 59-year-old woman presented with an embolic transient ischemic attack and a history of controlled hypertension for 16 years. Both echocardiogram and MRI showed severe biventricular hypertrophy and an apical aneurysm with a thrombus. The occurrence of an apical aneurysm in the presence of cardiac hypertrophy is a rare finding and has been described in patie

10. Myocarditis confirmed by biopsy presenting as acute myocardial infarction.
Two cases of acute myocardial infarction occurred in association with myocarditis, which was confirmed by biopsy. The first patient suffered an anteroseptal and the second patient an inferior wall myocardial infarction shortly after an acute viral illness. In both patients, coronary angiography showed normal coronary arteries, and right ventricular endomyoca

11. Myocardial biopsy in diagnosis of endomyocardiopathy in patient with electro- and vectorcardiographic signs of myocardial infarction.
A 52-year-old woman is described with the clinical picture of congestive heart failure, electro- and vectorcardiographic evidence of myocardial infarction, combined with angiographically hypokinetic left ventricle, but with patent coronary arteries. Endomyocardial biopsy disclosed changes consistent with 'congestive cardiomyopathy'. Thus, the study shows tha

12. Ultrastructural artefacts in biopsied normal myocardium and their relevance to myocardial biopsy in man.
Biopsy specimens, as a source of myocardial tissue, are being used increasingly in the appraisal of various myocardial diseases. A study of myocardial tissue, biopsied and processed in various ways, and obtained from normal healthy experimental animals, showed that a variety of artefacts may be found. These artefacts develop in reactive, beating myocardium b
