Isolated anterior mitral leaflet cleft (not associated with atrio-ventricular septal defect) is a rare cause of congenital mitral regurgitation, and the treatment consists of direct suturing of the cleft. We present a clinical case with this entity.
Apresenta-se o caso de um homem de 62 anos de idade com um episódio de dispneia súbita que motivou estudo ecocardiográfico, o qual revelou uma massa na aurícula direita. A avaliação posterior demonstrou tratar-se de extensão de neoplasia do rim direito. A massa tumoral foi removida através duma abordagem multidisciplinar, com cirurgia torácica e abdominal. O estudo anatomopatológico mostrou tratar-se de um carcinoma de células renais.
Introdução: Existe alguma controvérsia respeitante ao tipo de revascularização a efectuar no contexto de angioplastia (PCI) primária no enfarte agudo do miocárdio (EAM). A presença de lesões coronárias adicionais, particularmente complexas, poderá ter impacto no prognóstico.
Objectivos: Avaliar o prognóstico a médio-prazo (1 ano) face à presença de lesões adicionais complexas após PCI primária.
População e Métodos: Estudaram-se retrospectivamente 138 doentes consecutivos admitidos na nossa Unidade por EAM com elevação do segmento ST e submetidos a PCI primária. Os doentes foram seguidos por um período de 1 ano e divididos em 2 grupos: sem lesões adicionais complexas (n=69, 61 ± 14 anos, 62% sexo masculino) e com lesões adicionais complexas (n=69, 65 ± 13 anos, 73% sexo masculino, p=NS). Avaliaram-se as características demográfic...
Introdução: O tratamento das Síndromes
Coronárias Agudas (SCA) sofreu várias
alterações muito rápidas nos últimos anos,
traduzido nas múltiplas propostas de
recomendações pelo ACC/AHA/ESC, baseados
na evidência clínica. Avaliamos a
implementação destas recomendações,
comparando uma população de doentes de 2002, com uma população de 2005.
Métodos: Estudo retrospectivo de 368 doentes
admitidos em 2002 e 420 doentes admitidos em 2005 por SCA (com e sem elevação do segmento ST). Analisaram-se características clínicas e estratégias de tratamento.
Resultados: Não se verificaram diferenças em
termos de idade, sexo masculino, factores de
risco para doença coronária ou história prévia de revascularização miocárdica. Verificou-se uma redução de doentes com antecedentes de enfarte do miocárdico e insuficiência renal e aumento da apres...
INTRODUCTION: The definition of subclinical hypothyroidism (SH) is an asymptomatic state in which free thyroxine (T4) is normal and thyroid-stimulating hormone (TSH) levels are elevated. Its relationship with coronary disease is not clear and has been the subject of recent interest. Current evidence is conflicting and there is a lack of studies supported by coronary angiography.
OBJECTIVE: To assess the relationship between SH and the presence and extent of coronary disease diagnosed by angiography.
METHODS: We prospectively studied 354 consecutive patients referred for elective coronary angiography. Those with known thyroid disease, documented coronary disease or previous myocardial infarction were excluded. Fasting blood specimens were collected to measure thyroid hormones, lipid profile, high-sensitivity C-reactive protein, fi...
Cardiovascular disease is among the main causes of mortality and morbidity worldwide. Despite significant advances in medical and interventional therapy, the prognosis of
conditions such as ischemic heart disease is still dismal. There is thus a need to investigate
new therapeutic tools, one of which is stem cell therapy. Hematopoietic stem cells are the
most studied type, and the fact that their biology is relatively well understood has led to their
being used in preclinical research and clinical trials. However, the results of some of these
studies have been controversial, which has opened the way for studies on other cell types, such
as mesenchymal stem cells. These cells have immunomodulatory properties which suggest that
they have therapeutic potential in cardiology. In the present article, the authors review the
state of t...
INTRODUCTION: Mitral regurgitation (MR) is the most common valvular disease and has recently become the target of a number of percutaneous approaches. The MitraClip is virtually the only device for which there is considerable experience, with more than 20,000 procedures performed worldwide.
OBJECTIVE: To describe our initial experience of the percutaneous treatment of MR with the MitraClip device.
METHODS: We describe the first six MitraClip cases performed in this institution (mean age 58.5 ± 13.1 years), with functional MR grade 4+ and New York Heart Association (NYHA) heart failure class III or IV (n=3), with a mean follow-up of 290 ± 145 days.
RESULTS: Procedural success (MR ≤ 2+) was 100%. Total procedure time was 115.8 ± 23.7 min, with no in-hospital adverse events and discharge between the fourth and eighth day, and consisten...
Apresenta-se o caso de um doente avaliado por sopro cardíaco contínuo, em que o estudo ecocardiográfico permitiu diagnosticar ruptura de aneurisma congénito do seio de Valsalva (SV) para a aurícula direita. Os autores fazem uma breve revisão sobre os aspectos clínicos desta patologia.
INTRODUCTION: Renal insufficiency (RI) is associated with higher morbidity and mortality in patients (P) with coronary artery disease and in P submitted to angioplasty. In ST-segment elevation acute myocardial infarction (STEAMI), this impact has not been well demonstrated.
AIM: To evaluate the impact of RI in P with STEAMI.
METHODS: We evaluated 160 P admitted with STEAMI, mean age of 62+/-14 years, 76% male. We determined creatinine levels on admission. RI was defined as a level >1.5 mg/dl. Analysis of clinical, electrocardiographic and laboratory variables was performed, in relation to the endpoint defined as the occurrence of death at 30-day follow-up.
RESULTS: There were 16 deaths (10%) at 30-day follow-up. P with RI (n=21) were older (68+/-11 vs 61+/-14 years, p<0.001), more often had diabetes (57 vs 24 %, p=0.004) and p...
