RESUMO
Infective endocarditis (IE) is a rare, polymorphic disease in children. Mycotic aneurysm is a rare condition that complicates about 2.5 to 10% of cases of endocarditis. It is responsible for significant morbidity and mortality [1,2]. Mycotic aneurysms are often asymptomatic, physical examination is poor, but the diagnosis should be considered with the triad including fever, abdominal pain, and abdominal mass beating. Abdominal ultrasound and computed tomography are the most useful for the identification of the aneurysmal mass. However, angiography is an interesting addition to confirm the diagnosis and implement a treatment procedure [3]. The treatment of SMA aneurysms is largely surgical. IE treatment is based on antibiotic therapy combined with surgical repair. We report the case of a 15-year-old patient, first operated for an SMA aneurysm complicating the course of IE, who secondarily underwent mitral valve repair. We review the epidemiology, diagnosis, and care principles of mycotic aneurysms of the SMA.

Aneurysm of the superior mesenteric artery is a rare finding. The risk of rupture is difficult to predict and manage. We report the case of a young woman who developed an aneurysm of the superior mesenteric artery in a context of bacterial endocarditis. Surgical resection without revascularization was successful.

BACKGROUND: Aortic valve replacement improves clinical symptoms and left ventricular systolic function in patients with chronic aortic regurgitation despite a higher surgical risk. The objective of this study is to determine if left ventricular function will be normalized after surgery. PATIENTS AND METHOD: This retrospective study included 40 patients (nine females and 31 males) with chronic aortic regurgitation and left ventricular systolic dysfunction who were evaluated by echocardiography Doppler. Were included patients with left ventricular ejection fraction less or equal to 45%. Ages ranged from 18 to 77 years (mean = 46.4 ± 12.6 years). Preoperatively, six patients (15%) were asymptomatic, ten (25%) were in NYHA II, half (50%) in NYHA III and four (10%) in NYHA IV. The mean preoperative ejection fraction (EF) was 36.2 ± 2%. The mean end systolic and diastolic dimensions were 61.7 ± 8.5 mm and 78.9 ± 9.7 mm respectively. Aortic regurgitation was quantified grade III in sixteen patients (40%) and grade IV in twenty-four (60%). RESULTS: Thirty-seven patients underwent aortic valve replacement and three Bentall operations. Hospital mortality was 7.5% (3/40). The mean follow-up period was 69.7 months. All survivor patients were investigated. Out of these, five were lost and 32 were controlled. Symptomatic improvement was noted in most of the survivors. Sixty percent (24/40) were severely symptomatic before and only 6.25% (2/32) during follow-up. The ejection fraction increased significantly after surgery (36.2 ± 2% in preoperative period vs. 55.2 ± 10% in postoperative period, P < 0.02). Left ventricular diameters decreased significantly also. Survival rates were 3-year 94%, 5-year 91% and 7-year 89%. CONCLUSION: Despite reduced left ventricular systolic function, aortic valve replacement in chronic aortic regurgitation was associated with acceptable operative risk. Surgery improves functional status, symptoms and ejection fraction in most patients.
