Anomalous coronary origin: From suspicion to surgical revascularization

Congenital anomalies of the coronary arteries are uncommon and can present a diagnostic challenge. The authors present the case of a patient with recurrent chest pain during exertion admitted for acute coronary syndrome. Coronary angiography revealed no coronary lesions but showed that the right coronary artery originated from the anterolateral aortic wall, above the sinuses of Valsalva, leading to suspicion of...

Síndrome Febril e Coma. Considerações a Propósito de Um Caso Clínico

A endocardite infecciosa é relativamente pouco frequente na idade pediátrica, mas a sua morbilidade e mortalidade são elevadas.Os autores descrevem um caso clínico de endocardite infecciosa aguda por Staphylococcus aureus numa criança de 5 anos de idade, sem factores de risco conhecidos, diagnosticada na sequência de complicações neurológicas (degradação súbita do estado de consciência e sinais neurológicos foc...

Adventitious root formation in olive (Olea europaea L.) microshoots: anatomical...

Trials were performed using in vitro-cultured microshoots of the olive (Olea europaea L.) cultivar ‘Galega vulgar’, as initial explants, to identify histological events and modifications in peroxidase and polyphenol oxidase activities during adventitious root formation. Explant bases were submitted to a 10 s quick-dip treatment to promote rooting, using a sterile solution of 14.7 mM indole-3-butyric acid (IBA)....

Ischemic rupture of the anterolateral papillary muscle

We describe the case of a 59-year-old man who presented with chest pain and ST-segment elevation in the inferior leads, R>S in V1 and ST depression in the anterior leads due to proximal occlusion of the first obtuse marginal. Primary coronary angioplasty and stenting of this artery were performed. Twelve hours later the patient became hemodynamically unstable and severe mitral regurgitation due to rupture of on...

A rare cause of pericardial disease

Among cardiovascular diseases, pericardial disease has specific characteristics. Its etiology, diagnosis and medical management are not as well understood as in coronary and valvular heart disease. In most cases, its cause is benign, although the proportion decreases with more severe clinical presentation. The authors present the case of a 35-year-old man with no relevant past medical history, who went to the e...

Takotsubo cardiomyopathy: a rare, but serious, complication of epileptic seizures

Mesalamine-induced myocarditis following diagnosis of Crohn's disease: a case r...

Mesalamine is a common treatment for Crohn's disease, and can be rarely associated with myocarditis through a mechanism of drug hypersensitivity. We present the case of a 19-year-old male who developed chest pain two weeks after beginning mesalamine therapy. The electrocardiogram showed slight ST-segment elevation with upward concavity in the inferolateral leads; blood tests demonstrated elevated troponin I and...
