Öğe Akut miyokard enfarktüsü sonrası gelişen geniş ventriküler septal rüptürün başarılı tedavisi(Aves, 2007) Kaya, Ahmet; Kaya, Yasemin; Ordu, Serkan; Özkökeli, Mehmet; Özhan, Hakan; Dağlar, Bahadır; Yazıcı, MehmetPostinfarct ventricular septal rupture (VSR) is a rare but mortal complication of acute myocardial infarction (MI). VSR must be diagnosed earlier and the correct treatment must be applied immediately. Abrupt surgical repair is the choice of treatment, which decreases early mortality and improves long term survival. Septal rupture occurs more frequently with anterior than with other types of acute myocardial infarction. VSR occurs usually within 2 weeks after infraction. We describe here a 76-year-old woman with a giant VSR with little hemodynamic disturbance that developed twenty days after anterior myocardial infarction. She was successfully treated with abrupt surgical closure.Öğe Association between BNP and in Stent Restenosis in Patients who had Undergone Coronary Angioplasty(Aves, 2007) Kaya, Ahmet; Kaya, Yasemin; Ordu, Serkan; Albayrak, Enver Sinan; Satilmisoglu, M. Hulusi; Erkan, Melih Engin; Ozhan, HakanIntroduction: Brain natriuretic peptide (BNP) is a highly sensitive and specific diagnostic tool used in prediction of cardiovascular events in patients with ischemic and non-ischemic cardiovascular heart disease. In this study, we sought to test the efficacy of BNP in predicting restenosis rate in patients who had undergone PCI. Materials and Methods: Seventy-three consecutive stable angina and acute coronary syndrome patients who were admitted to cardiology department and performed percutaneous coronary intervention (PCI) were included in this study. The study was performed in Duzce University School of Medicine, Dept of Cardiology between 2006 and 2008. Pre and post PCI BNP levels were measured in all the patients. The patients were followed up for stent restenosis. Results: Sixteen out of 23 patients who were screened for restenosis with coronary angiography were found to have restenosis. The differences between the mean BNP levels measured before and after PCI were not statistically significant. Conclusion: BNP measured before and after PCI could not predict restenosis.Öğe A case successfully treated giant ventricular septal rupture after acute myocardial infarction(Springer, 2007) Kaya, Ahmet; Kaya, Yasemin; Ordu, Serkan; Özkökeli, Mehmet; Özhan, Hakan; Dağlar, Bahadır; Yazıcı, MehmetVSR occurs in 1-3 % of all MI cases, usually within 2 weeks after infraction. 50-80% of partients die within the first week after the rupture unless they are surgically treated.Öğe A closed interatrial septal aneurysm mimicking a tumor in the left atrium(Texas Heart Inst, 2006) Akdemir, Ramazan; Duran, Sadık; Bulur, Serkan; Kaya, Ahmet; Sözen, Serhat Bahadır; Bilir, Cemil; Arınç, HüseyinA56-year-old woman presented with a congenital atrial septal aneurysm (ASA) that was found incidentally on routine echocardiographic evaluation. The echocardiographic images mimicked a left atrial tumor. She had hypertension, and she had been taking amlodipine for 5 years. There was no audible murmur. The chest radiograph and electrocardiogram were normal. Two-dimensional echocardiography showed rheumatic valvular disease and a mobile mass in the left atrium that resembled a cyst or cor triatriatum sinister. Further evaluation by other echocardiographic views confirmed the ASA.Öğe Correlation of plasma B-type natriuretic peptide with shunt severity in patients with atrial or ventricular septal defect(Springer, 2007) Özhan, Hakan; Albayrak, Sinan; Uzun, Hakan; Ordu, Serkan; Kaya, Ahmet; Yazıcı, MehmetThe goal of this study was to test the utility of bedside plasma concentration of B-type natriuretic peptide (BNP) assay as a screen for large shunts in pediatric patients with atrial septal defects (ASDs) and ventricular septal defects (VSDs). Thirty-five children at a mean age of 70 +/- 129 weeks with ASD or VSD were included in the study. Nine patients had VSD and 26 had ASD. Plasma BNP values were compared with the Q(p)/Q(s) ratios derived from quantitative Doppler flow measurements. Mean BNP was 29 +/- 42 pg/ml, with a range between < 5 pg/ml and 208 pg/ml. Sixteen patients had Q(p)/Q(s) values > 1.5 and 19 had values < 1.5. The difference of mean BNP in these patient groups was statistically significant (45 +/- 56 vs 14 +/- 17, p = 0.03). BNP was positively correlated with shunt significance. Receiver operating characteristic curve analysis revealed a sensitivity of 69% and a specificity of 79% at a plasma BNP cut-off level of >= 20 pg/ml. Bedside measurement of BNP correlates with magnitude of ASD and VSD in children. BNP can provide information for the management of children with ASD or VSD. It can be used as part of the evaluation of a child with a preliminary diagnosis of a congenital defect.Öğe Deer horn image in the liver associated with giant right atrium(Le Jacq Ltd, 2007) Akdemir, Ramazan; Yıldız, Ahmet; Bulur, Serkan; Kaya, Ahmet; Bilir, Cemil; Uyan, CihangirA 65-year-old man was brought to the hospital complaining of massive bilateral leg swellmurmur in the xiphoid and mesocardiac regions. His electrocardiogram revealed atrial fibrillation, while his chest x-ray showed cardiomegaly.Öğe Performance of Bioelectrical Impedance Analysis in the Diagnosis of Metabolic Syndrome(Bmj Publishing Group, 2012) Ozhan, Hakan; Alemdar, Recai; Caglar, Onur; Ordu, Serkan; Kaya, Ahmet; Albayrak, Sinan; Turker, YasinObjective: Central obesity is a prerequisite for the diagnosis of metabolic syndrome (MetS). Precise measurement of visceral fat by bioelectrical impedance analysis (BIA) has been validated. The aim of this study was to investigate the diagnostic performance of BIA in MetS and validate the best cutoff in a large adult cohort. Materials and Methods: The study was performed on the MELEN Study cohort-a prospectively designed survey on the prevalence of cardiometabolic risk factors in Turkish adults. The final cohort consisted of 2219 participants. Weight and visceral body composition were measured without shoes in light indoor clothes using a bioimpedance analyzer (Omron BF 510; Omron Corp, Kyoto, Japan). Plasma concentrations of cholesterol, insulin, fasting triglycerides, high-density lipoprotein cholesterol, glucose, and other biochemical variables were measured. The diagnostic performance of visceral fat measurement by BIA in patients with MetS was assessed. Results: Metabolic syndrome was detected in 751 participants (520 women and 231 men with a mean age of 55 [12] years; 34% of the whole study population). Total body fat and visceral fat levels were higher in subjects with MetS. Correlation analyses showed that there were significant correlations between anthropometric and BIA measurements. Receiver operating curve characteristics of visceral adiposity revealed the best cutoff values as greater than 12% for men and greater than 9% for women. The diagnostic performance was good in both sexes (the sensitivity/specificity and area-under-the-curve values were 76%/75% and 0.83 for men and 83%/67% and 0.81 for women, respectively). Conclusions: Visceral fat measured with BIA is an easily applicable and useful method for identifying people with MetS. The best cutoff values were higher than 12% for men and higher than 9% for women.Öğe Pulmonary embolism during echocardiography: Thrombus in transit(2006) Özhan, Hakan; Kaya, Ahmet; Yazıcı, Mehmet; Albayrak, Sinan; Erbilen, Enver; Bulur, Serkan[No Abstract Available]
