Yayın Aortic root replacement (bentall procedure): Single surgeon experience(2003) Arsan S.Objective: This study was prompted in part by a theory based on the impression that aortic root replacement (ARR) in the elderly has a high morbidity and mortality. Methods: Retrospective analysis of 58 patients following ARR was carried out between 1996-2002. All the operations were performed by the author-an experienced surgeon. The choice of first assistant was based solely on availability; certified cardiovascular surgeon or experienced registered nurse. Patients were divided into two groups: group 1 patients were < 70 years of age and group 2 were > 70 years of age. The distribution of patients was similar in each group, as was the surgical strategy and concomitant surgical procedures. Results: The hospital mortality was 3 (8.3%) for group 1 patients and 2 (9.1%) for group 2 patients. The mortality and morbidity rates were dependent of the patient NYHA status, as were the cardiopulmonary bypass time, the aortic cross clamp time, blood loss, adjusted blood transfusion volume and concomitant procedures. Conclusion: ARR in the elderly is safe, the long term result is good and it remains the treatment of choice unless there is an absolute contraindication.Yayın Cor triatriatum in a 60-year-old woman became symptomatic after papillary cordae rupture(2002) Akgün S.; Yildirim T.; Türkmen M.; Arsan S.We describe a case of cor triatriatum in a 60-year-old woman. The diagnosis was initially made by transesophageal echocardiography after the presentation of the patient with pulmonary edema caused by papillary cordae rupture. The patient made an uneventful recovery after membrane resection and mitral valve replacement.Yayın How to avoid problems with reduction aortoplasty [4] (multiple letters)(2004) Arsan S.; Bauer M.; Grauhan O.; Hetzer R.…Yayın Interesting coronary artery aneurysm case [·Ilginç bir koroner arter anevrizmasi görüntüsü](2003) Yildirim T.; Kurtoglu N.; Arsan S.; Dindar I.…Yayın Isolation ratio and T-serotyping of group A streptococci from pediatric upper respiratory tract infections in Turkey(2005) Topkaya A.E.; Yildirim T.; Arsan S.Objective: Acute rheumatic fever can follow throat infections with group A streptococci. Certain serotypes of group A streptococci such as M1, M3, M5, M6, M14, M18, M19, M24 are associated with this disorder. Immunity to streptococci and to rheumatic fever depends on antibodies to the M proteins. Due to current scarcity of M-typing sera, many laboratories use T typing and opacity factor production for serotype identification of group A streptococci. In order to, investigate the most common serotypes of group A streptococci in our country in recent years we studied T-agglutination typing and opacity factor of 120 group A streptococci strains isolated from throat cultures of 930 children. Methods: Diffuse, stable suspensions of group A streptococci were tested with polyvalent antisera (T,U,W,X,Y) by slide agglutination. Microplate method was used for opacity factor detection. Results: T-protein -agglutination patterns U (2,4,6,28) were the most common among typeable strains. The rate of T-protein -agglutination patterns T (1,3,13, B3264) and X (8,14,25,lmp.19) were 20% and 18% respectively. Opacity factor production rate of isolated group A streptococci strains was 65%. Conclusion: To profit global assessment of rheumatic fever and rheumatic heart disease, more epidemiologic and serotyping research is required in our country.Yayın The role of surgery in iatrogenic dissection during in-stent restenosis treatment(2002) Civelek A.; Yildirim T.; Akgün S.; Isbir S.; Arsan S.In-stent restenosis (ISR) remains a challenging problem, and its optimal management is still unknown. Although redilatation has predominantly been used, unusual complication such as coronary artery dissection may occur. This report describes successful surgical treatment of a severe coronary artey dissection in the left anterior descending coronary artery after attempting eximer laser angioplasty for in-stent restenosis.
