Background: Cardiac hydatidosis is a rare manifestation of Echinococcus infection. It represents 0.5 to 2% of hydatic disease (Mustafa et al., Can J Cardiol 22:2, 2006). The most common localization is the myocardium of the left ventricle but can also touch the right ventricle, atrium, pericardium, interventricular septum, and pulmonary artery. Clinical presentation is varied ranging from clinical latency or minor symptoms to cardiogenic shock and sudden death. The present case describes a primary pericardial hydatid cyst, a very exceptional localization of cardiac hydatidosis, which can lead to a delayed diagnosis or to an erroneous treatment that can expose the life of the patient to complications and death if it is not considered. Diagnosis can be established by cardiac imaging and hydatid serology. Therapy management should combine both surgery and medical treatment by albendazole or mebendazole. Case presentation: We report a 70-year-old woman from Sale, who was admitted for dyspnea New York Heart Association (NYHA) class IV evolving in a febrile context with signs of right heart failure related to a rupture of a primary pericardial hydatid cyst with pre-tamponade. The diagnosis was confirmed by echocardiography, computed tomography scan (CT scan), and hydatic serology, and the patient was operated and put on albendazole for 3 months with favorable clinical course. Conclusions: The aims of this article are to consider the diagnosis of cardiac hydatid cysts in the presence of pericardial effusion, especially if there is a prior history of hydatid disease, a contact with animals, or when it occurs in an endemic country, and to be able to make a differential diagnosis with cardiac imaging in order to avoid its complications and to guide the management.

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndromes (ACS) that mainly occurs in young women with no risk factors and no coronary atherosclerosis. Diagnosis is made by invasive coronary angiography (CA), computed tomography coronary angiography (CTCA), intravascular ultrasound (IVUS) and optical coherence tomography (OCT). The rarity of this entity as well as the complications of invasive treatment make it difficult to choose therapy between conservative management, percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). We report a case of a 36-year-old woman presented with non ST elevation myocardial infarction (NSTEMI) related to spontaneous dissection of coronary arteries (left main trunk, left anterior descending artery and left circumflex artery) treated medically with spectacular results at 2 months, controlled by CTCA.

The ductus arteriosus, an essential fetal structure, normally closes spontaneously soon after birth. Its persistence into late adulthood is considered to be rare; infective endarteritis (IE) complicating a patent ductus arteriosus (PDA) is an even rarer event. The clinical picture of an infected PDA could be subtle, and the diagnosis is frequently delayed. We present the case of a young woman who presented with prolonged fever for whom we made the diagnosis of a PDA complicated by IE, with vegetations in both pulmonary and aortic walls with mycotic aneurysms of the descending aorta. She underwent surgery and the post-operative course was uneventful. To our knowledge, this is the first reported case of a PDA complicated with both pulmonary and aortic endarteritis.
