Papillary fibroelastoma revealed by an acute coronary syndrome with transient ST segment elevation: a case report.

Cardiac papillary fibroelastoma is a rare, benign tumour, arising from the valvular endocardium, which could lead to life-threatening complications as myocardial ischemia. We report a case of a 54-year-old male patient who presented in the emergency room with an acute coronary syndrome with transient ST segment elevation. After ruling out coronary artery disease by coronarography, we established the diagnosis of papillary fibroelastoma by performing echocardiogram completed by computed tomography angiography. The reversible acute coronary syndrome has been caused by the prolapse of pedunculated coronary cusp tumour into the main left coronary ostium. The patient was scheduled for emergent surgery. The surgical management included a complete resection of the tumour sparing the aortic valve. The patient recovered well. A papillary fibroelastoma of the aortic valve can be revealed by an acute coronary syndrome with transient ST segment elevation. More investigations must be done to eliminate such diagnosis in the case of a normal coronarography.

Infective endocarditis following COVID-19 pneumonia: about two cases.

Coronavirus disease 2019 (COVID-19) has emerged as a pandemic and public health crisis across the world. The severity of this situation is escalating in certain populations, particularly when the COVID-19 diagnosis may delay the recognition of more dramatic illnesses such as infective endocarditis, which is a dreaded complication in patients with cardiac disease. We report the case of two patients who presented with infective endocarditis initially mistaken for COVID-19 pneumonia, which was responsible for a delay in diagnosis. We discuss the diagnostic difficulties as well as the management of this complication in the COVID-19 era. As a physician, one must remain alert to this dreaded complication, especially in patients with a cardiac history, in order to prevent it, detect it early, and manage it in time.

Co-existence of severe coarctation of the aorta and aortic valve stenosis in adulthood: a case report.

Aortic coarctation is a congenital heart disease that usually presents and is treated in the childhood. The aortic coarctation is often associated with concomitant cardiac pathologies, such as aortic stenosis and bicuspid aortic valve. We report the case of a 56-year-old man, admitted in our cardiologic unit, for sudden onset of chest pain, dyspnea and syncope. Aortic coarctation with aortic valve stenosis was diagnosed. The aortic valve was successfully replaced in the first stage; the coarctation had to be treated in a second time.

Acute Bilateral Renal Infarction: An Unusual Complication After Mitral Valve Replacement Surgery.

Bilateral renal infarction is an uncommon clinical condition that is frequently misdiagnosed. Its various mechanisms mainly include thrombotic and embolic. We report the case of a 51-year-old Moroccan woman, who presented with acute bilateral renal infarction three days following mitral valve replacement surgery of probable embolic origin despite curative heparin. Her renal function did not improve, and the patient developed chronic renal failure. Diagnosing bilateral renal infarction is challenging, especially in the postoperative period of mechanical mitral valve replacement surgery. Curative heparin therapy does not totally protect (100%) against this serious complication. This case study aimed to raise awareness of this rare clinical condition after cardiac surgery.

Surgical repair of a pseudocoarctation with cervical aortic arch complicated by multiple aneurysms of the aorta: a case report.

Aortic pseudocoarctation is a rare congenital anomaly characterized by elongation and deformity of the aortic arch and is known to be associated with aneurysmal formation. Several studies unite to say it leads to a surgical sanction as soon as symptomatic or associated with aneurysms of the aortic arch. Our patient is a 12 years old boy, followed since birth for a little tight pseudocoarctation with a cervical aortic arch and transverse aortic arch hypoplasia. Close clinical and paraclinical monitoring including angioscans, showed the gradual enlargement of the superior mediastinum, in relation with the appearance of three aneurysms of the aortic arch. The intervention, performed by sternotomy, has consisted of the resection of the aneurysmal area and the interposition of a Dacron tube to repair the aortic arch and the reimplantation of the left subclavian artery into the left carotid artery. The postoperative course was uneventful. Management of pseudocoarctation associated with cervical aortic arch and aneurysms remains surgical. Close monitoring of patients with pseudocorctation, seems to be essential to avoid fatal complications such as aneurysmal rupture.
