We present the unusual case of an AMI STEMI, complicated by ventricular fibrillation, in a 26 years old caucasic male patient, affected by necrotizing and granulomatous aortitis, in the context of a primary immunodeficiency. Initially the patient was referred to the Cardiology Unit for worsening dyspnea and fatigue. In his medical history he has primary immunodeficiency complicated by multiple opportunistic infections. We performed an echocardiography that revealed an aneurismatic ascending aorta (58 mm) with associated significant aortic valvular regurgitation. He was later referred to heart surgery OR where Bentall-De Bono operation was performed. Two years later he developed a lateral STEMI, complicated by ventricular fibrillation. The coronary angiography, performed in foreign country, showed total occlusion of the circumflex coronary artery with diffuse aneurismatic coronary disease, granulomatosis and ulcerative lesions. A percutaneous revascularization approach was tried, but ineffective. Actually the patient, during follow up, presents dilatative post-ischemic cardiopathy with moderate ejection fraction reduction, initial aortic bioprosthesis failure. We noted at follow up echocardiograms early dilatation of the native aortic arch (35 mm), suggesting a progressive disease. In conclusion, AMI's etiology includes many non atherosclerotic mechanisms that should be considered alongside common causes. This case shows a rare cause of STEMI in a very young male patient, and teaches us that aortitis is a progressive and complex pathology, often involving multiple arteriosus districts, that needs close follow-up and integrated management.

Abstract:The effect of a position measurement on one component of a two-particle wave packet in a regularized space-momentum entangled state is analyzed. The wave packet interacts in the physical space with a potential barrier. When a position or momentum measurement is performed on one particle, a consequent strong modification of the dynamics of the other particle occurs.

This case describes a cardiac tamponade in systemic lupus erythematosus (SLE), an uncommon but life-threatening condition that needs prompt recognition. A 33-year-old woman with therapy-resistant SLE presented to the Emergency Department with chest pain and fever for 3 days. She was hemodynamically stable, the ECG showed signs of pericarditis and echocardiography showed a minimal pericardial effusion. Pericarditis was diagnosed and the patient was admitted to the Cardiology Ward. Seven hours later her symptoms deteriorated, presenting hemodynamic instability with hypotension and tachycardia. The ECG showed low QRS voltage and electrical alternans, echocardiography confirmed cardiac tamponade. The patient underwent an emergency pericardiocentesis with 220 mL of serous citrine liquid removed and immediate regression of symptoms. The cytology exam revealed inflammatory cells with no evidence of malignancy, blood culture and effusion fluid's tests came back negative. A Thoraco-abdominal CT revealed also bilateral pleural effusion (not present at the admission) and ascites. Signs, symptoms and medical history suggested SLE flare-up and high-dose oral glucocorticoid therapy was started. Our report highlights a rare presentation of life-threatening polyserositis in SLE flare-up. Although pericarditis and pericardial effusion are frequently-reported SLE's cardiovascular complications, rapid development of cardiac tamponade is far from common. Acute cardiac tamponade, like in our case, is an indication for emergency pericardial drainage to restore an adequate cardiac output. We describe an out of ordinary case of a patient in whom an accurate and timely diagnosis of SLE–related cardiac tamponade has been live–saving.
