RESUMO
Myxoma is the most common type of primary tumors of the heart in adults. The majority of patients with myxomas may experience symptoms due to central or peripheral embolism or intracardiac obstruction, while in some cases, they may be completely asymptomatic. Rarely, patients develop unusual symptoms that complicate the diagnostic evaluation. Herein, we describe the case of a 70-year-old patient with a long-lasting low-grade fever due to a large left atrial myxoma revealed during a transthoracic echocardiography.

Spontaneous coronary artery dissection (SCAD) represents a rare cause of acute coronary syndromes with complex pathohysiology. We briefly describe a 50-year-old woman, without traditional cardiovascular risk factors, hospitalized for an acute ST-elevation myocardial infarction and treated with thrombolytic therapy. Notably, the patient was on oral contraceptives for the past 10 years. Coronary angiography showed a dissection of the distal left anterior descending artery. She was treated conservatively and her clinical status improved without evidence of continuing ischemia, while a repeated catheterization 6 months later showed a complete resolution of the dissection. It has been speculated that the female hormones may be responsible for the increased incidence of SCAD among women particularly during the peripartum period or during the exogenous administration of such agents. A systematic review of the literature revealed 4 further cases reporting an association of SCAD with oral contraceptive use.
