Respiratory distress in a patient with Klinefelter syndrome: a suspicion of COVID-19 hiding severe pulmonary embolism.

Klinefelter syndrome is the most common congenital abnormality causing primary hypogonadism and predisposing to a state of hypercoagulability. We report the case of a 37-year-old man, of Algerian nationality, diagnosed with Klinefelter syndrome admitted to the hospital via the emergency room for acute chest pain and dyspnea. The patient arrived in Tunisia 36 hours ago.

[Sudden cardiac death of rhythmic origin in athletes: literature review].

The sudden death in athletes is, in the vast majority of cases, related to ventricular fibrillation, often in a subject with unknown cardiovascular abnormality; this dramatic event has a significant impact on society and the medical profession. We conducted through a literature review an analysis of data on sudden cardiac death of rhythmic origin in athletes; sudden death may be cardiovascular in 95.3% of cases and related to ventricular arrhythmia in 88% cases.

[A rare cause of myocardial infarction: carbon monoxide intoxication].

We describe a 34-year-old man who suffered an acute myocardial infarction after carbon monoxide domestic exposure. The coronary angiogram was normal. The necrosis is explained in part by a severe coronary spasm.

[Congenital coronary aneurysm. Three case reports].

Congenital coronary aneurysms are an unusual anatomical entity. Their prognosis appears to be particularly dependent on the presence or absence of aneurysm thrombosis. We report three cases of congenital coronary aneurysms, diagnosed in one case after myocardial infarction.

[Left main coronary stenosis: clinical and paraclinical aspects].

The authors report a retrospective study about 20 cases of left main coronary disease admitted during 7 years. The mean age is 60 years with a large predilection for men (65% cases). The left main coronary stenosis generally presented as instable angina in 45% cases, myocardial infarct in 40% cases and left ventricular dysfunction in 10% cases.
