RESUMO
BACKGROUND: The syndrome of mitral valve prolapse (MVP) is the most common form of valvular heart disease. CASE REPORT: The case of a 16-year-old girl with mitral valve prolapse, atrial flutter and syncope is presented. The patient was admitted to the clinic complaining of atypical chest pain, palpitations, breathlessness at physical efforts, fatigue, and a feeling of fogginess. Electrocardiogram showed the presence of the common-type atrial flutter with 3:1 ventricular responses. Echocardiography showed mitral valve prolapse with mild mitral regurgitation. The patient reported to have had these symptoms for about nine months. She was not aware of heart disease before. CONCLUSIONS: A young female patient with combined mitral valve prolapse, atrial flutter, and syncope is presented.

BACKGROUND: Acute myocardial infarction is a rare complication of mitral stenosis. Acute myocardial infarction in the setting of severe unrecognized mitral stenosis has not been described. CASE REPORT: A 47-year-old-woman was admitted to our department for chest pain typical of myocardial infarction. Electrocardiogram showed ST segment elevation in leads II, III, and aVF and atrial fibrillation. Creatine kinase level was elevated to 268 U/L. The diagnosis of acute myocardial infarction of the inferior wall was established. The patient reported breathlessness after physical exertion over the last 2 years; however, she had not sought medical help and was unaware of her heart disease. Transthoracic echocardiography showed severe mitral stenosis (surface mitral valve area <1 cm2) and inferior wall akinesia. CONCLUSIONS: We present a case of acute myocardial infarction in a patient with unrecognized severe mitral stenosis and atrial fibrillation. Our suggestion is that acute myocardial infarction in this patient with no risk factors for coronary atherosclerosis was of thromboembolic origin, from left atrial thrombi.

We present the case of a 71-year-old woman with a 7-year history of a giant left atrial myxoma. The myxoma was attached to the atrial septum and occupied almost the entire left atrial cavity. The patient was hospitalized 4 times because of dyspnea on exertion, palpitations, fatigue, general asthenia, and weight loss. During prior hospitalizations, the patient had refused cardiac surgery. She developed several complications, including atrial fibrillation, mitral and tricuspid regurgitation, mesenteric embolism, pulmonary edema, and thrombotic stroke. We herein describe the natural history of left atrial myxoma in an elderly patient over a 7-year period.
