We report the case of a 36 years-old male, who was admitted to the cardiology department for prolonged fever, NYHA II Dyspnea and asthenia. Clinical examination found a febrile patient (39.2 °C) with diffuse purpiric spots and a 4/6 diastolic murmur in the Aortic area. Blood tests revealed high C-reactive protein level (236 mg/L) and procalcitonin(4.6 mg/L), in addition to hyperneutrophilia (18000/mm3), Anemia of Inflammation (Hb= 7.1 g/dL) and thrombopenia (98000/mm3). Renal function was altered ( GFR(MDRD)= 37 mL/min), Urine tests found high proteinuria (3g/24h) and hematuria. Transthoracic Echocardiography (TEE) was performed and showed tickened Aortic Valves with two large vegetations on the ventricular side of the Aortic cuspis measering 22x16mm and 12x17mm respectively, associated to a severe acute aortic regurgitation and a suspected sievers type 1 Bicuspid Aortic Valve (BAV). Moreover, a restrictive Ventricular Septal Defect (VSD) of 5 mm was found, in addition to an important tricuspid insufficiency and a transvalvular gradient estimated to 57 mmHg. Repeated Blood cultures were sterile, thus, empirical antibiotherapy including Vancomycin and Gentamicin was initiated and the patient underwent surgery with Aortic Valve Replacement and Tricuspid annuloplasty. The Sievers I/LR BAV was confirmed in peroperative findings. Post-operative period was marked with a favorable evolution with apyrexia, inflammation markors normalization and no residual vegetation in the post-operative TTE. The patient was discharged from hospital as he was asymptomatic and was regularily followed-up.
