    Asymptomatic and isolated accessory mitral valve tissue in adult population: three case reports and review of the literature.
    (2012) Cil H.; Atilgan Z.A.; Islamoglu Y.; Yavuz C.; Tekbas E.O.
    Accessory mitral valve tissue is a rare congenital cardiac anomaly and commonly it may cause left ventricular outflow tract obstruction (LVOTO). This anomaly occurs as a part of other congenital cardiac anomalies. However, it may be seen isolated. Structures in LVOT such as tumor, vegetation, cysts may have attention for differential diagnosis. The number of cases is increasing with the routinely using of two-dimensional echocardiography. Accessory mitral valve tissue is detected first early in children with symptoms of LVOT and is very rarely diagnosed in adults. One third of cases may asymptomatic, but commonly significant left ventricular outflow tract gradient can be detected in these cases, especially adult period. Optimal treatment of this anomaly is surgery if there is a significant LVOTO. In this report, we presented the three asymptomatic adult cases with accessory mitral valve tissue, without increased gradient in LVOT. Surgical excision was recommended to the first case in another hospital with diagnosis of cardiac cyst. Two cases are presented.

    General features of infective endocarditis in the South-eastern and Eastern anatolia: A retrospective, multicenter study
    (2012) Islamoglu Y.; Aksakal E.; Kaya Z.; Atilgan Z.; Kayan F.; Sunbul S.; Kalkan K.
    The present study aimed to evaluate general features of infective endocarditis (IE) in multiple tertiary university hospital. The study included 44 patients (23 women, 21 men; mean age 44±19 years; range 15 to 85 years) who were diagnosed as having definite IE, according to the modified Duke criteria, between June 2007 and June 2011. Data were reviewed on age, sex, underlying heart disease, echocardiographic and microbiological findings, treatment, complications, and mortality. Infective endocarditis developed on a native valve in 30 (72.7%), a mechanical prosthetic valve in 12 (27.3%). Prosthetic valves 12 (27.3%) were the most common preexisting valvular abnormality. The mitral valve was the most commonly affected valve in both native valves (50%) and prosthetic valves (66.6%). The most frequent symptom was fever (n = 27, 61.4%). Electrocardiography showed abnormal findings in 22 cases (50%). Transthoracic and/or transesophageal echocardiography showed a vegetation in 41 cases (93.2%), and absce 3 cases (6.8%). Staphylococci (29.6%) and streptococci (25%) were the most common causative agents ,and Brucella were 15.9%. Cultures were negative in 7 cases (15.9%). Nine patients (20.4%) underwent surgical treatment. Embolic events (n = 6, 35.3%) were the major complications. In-hospital mortality occurred in 6 cases (13.6%). The data reflect epidemiological, clinical, and microbiological profile of IE in multiple tertiary hospital located in the South-eastern and Eastern Anatolia.
