Introduction:Radiofrequencycatheter ablation therapy has been used to treat arrhythmia such assupraventricular and/or ventricular tachycardia. Increased waist circumferenceis important in assessing central obesity and may be an important factor forradiation injury. Therefore, this article describes the association betweenwaist circumference and fluoroscopic exposure time during cardiacradiofrequency catheter ablation procedures for symptomatic drug-resistanttachycardia.Patientsand Methods: From August 2011 to March 2015, 214 (136 women, 78 men)consecutive patients with symptomatic drug-resistant atrioventricular nodalre-entrant tachycardia (174 patients), atrioventricular re-entrant tachycardia(12 patients), Wolf-Parkinson-White syndrome (5 patients), atrial tachycardia(8 patients), atrial flutter (7 patients), right ventricular outflow tracttachycardia (5 patients), and atrial fibrillation (3 patients) underwent aninvasive electrophysiological study and radiofrequency catheter ablation. Thefluoroscopic exposure time, radiofrequency catheter ablation time, and waistcircumference were measured during the electrophysiological study.Results: Althoughage was significantly higher in women than in men, body weight, body height,waist circumference, and radiofrequency catheter ablation time weresignificantly higher in men than in women. There was a correlation betweenwaist circumference and fluoroscopic exposure time (p= 0.04, r= 0.13).Conclusion: The study showed thatthere was a positive correlation between waist circumference and fluoroscopicexposure time in patients with antiarrhythmic drug-refractory tachycardia whounderwent radiofrequency catheter ablation. This finding could help preventradiation injury, especially increased waist circumference duringradiofrequency catheter ablation., Giriş: Radyofrekans kateter ablasyon tedavisi supraventriküler ve/veyaventriküler aritmilerin tedavisinde kullanılmaktadır. Artmış bel çevresisantral obeziteyi değerlendirmede önemli bir yöntemdir, aynı zamanda radyasyonhasarı için de önemli bir faktör olabilir. Bu nedenle bu makale semptomatikilaca dirençli taşikardi nedeni ile yapılan kardiyak radyofrekans kateterablasyonu sırasındaki floroskopi maruziyet süresi ile bel çevresi arasındakiilişkiyi irdelemektedir.Hastalar ve Yöntem: Ağustos 2011 ila Mart 2015tarihleri arasında semptomatik ilaca dirençli; atriyoventriküler nodalre-entran taşikardi (174 hasta), atriyoventriküler re-entran taşikardi (12hasta), Wolf Parkinson White sendromu (5 hasta), atriyal taşikardi (8 hasta),atriyal flutter (7 hasta), sağ ventriküler çıkış yolu taşikardisi (5 hasta),atriyal fibrilasyon (3 hasta) nedenleri ile invaziv elektrofizyolojik çalışmave radyofrekans ablasyon uygulanan 214 (136 kadın, 78 erkek) ardışık hastaçalışmaya dahil edildi. Floroskopi maruziyet süresi, radyofrekans ablasyonzamanı ve bel çevresi işlem sırasında ölçüldü.Bulgular: Kadınların yaşı anlamlı olarak erkeklerden yüksek olsada vücut ağrılığı, boy, bel çevresi ve radyofrekans ablasyon süresi erkeklerdekadınlara göre daha anlamlı olarak yüksekti. Bel çevresi ile floroskopimaruziyet süresi arasında bir korelasyon mevcuttu (p= 0.04, r= 0.13).Sonuç: Çalışmamız göstermiştirki,antiaritmik ilaç dirençli taşikardi nedenli radyofrekans kateter ablasyonuygulanan hastalarda floroskopi maruziyet süresi ile bel çevresi arasındapozitif bir korelasyon mevcuttur. Bu bulgu özellikle artmış bel çevresi olan hastalardaradyofrekans kateter ablasyon sırasında radyasyon hasarını önlemek için faydalıolabilir.

Hepatit Cvirüsü (HCV) tedavisinde peginterferon (Peg-IFN)2b ve ribavirin tedavisi konvansiyonel interferon veribavirin tedavisinden daha etkilidir. Peg-IFN ve ribavirin tedavisinin önemlietkilerinin yanında ateş, halsizlik, heyecan, huzursuzluk, nötropeni ve trombositopenigibi bir çok yan etki görülebilir. Ayrıca kardiyak aritmiler ve senkop gibinadir olaylar da Peg-IFNtedavisine bağlı gelişebilir. Bizler bu çalışmada Peg-IFN ve ribavirin tedavisi sırasında presenkop atağı vereenteran taşikardilerin en sık formu olan atriyoventriküler nodal reenterantaşikardi gelişen bir yoğun bakım hastasını sunuyoruz., Thetreatment of hepatitis C virus (HCV) with peginterferon (Peg-IFN) α2b andribavirin is more effective than with conventional interferon and ribavirin.Despite the important effects of Peg-IFN and ribavirin therapy, many sideeffects, such as fever, fatigue, anxiety, irritability, neutropenia andthrombocytopenia, may be observed. In addition, cardiac arrhythmias and syncopeare rare consequences of Peg-IFN therapy. In this study, we report an intensivecare unit patient who developed atrioventricular nodal reentrant tachycardia(AVNRT), which is the most common type of reentrant supraventriculartachycardia, and presyncopal attack during Peg-IFN and ribavirin therapy.

Introduction: We aimed to develop a classification method to discriminate ventricular septal defect and atrial septal defect by using severalhemodynamic parameters.Patients and Methods: Forty three patients (30 atrial septal defect, 13 ventricular septal defect; 26 female, 17 male) with documentedhemodynamic parameters via cardiac catheterization are included to study. Such parameters as blood pressure values of different areas,gender, age and Qp/Qs ratios are used for classification. Parameters, we used in classification are determined by divergence analysismethod. Those parameters are; i) pulmonary artery diastolic pressure, ii) Qp/Qs ratio, iii) right atrium pressure, iv) age, v) pulmonary arterysystolic pressure, vi) left ventricular sistolic pressure, vii) aorta mean pressure, viii) left ventricular diastolic pressure, ix) aorta diastolicpressure, x) aorta systolic pressure. Those parameters detected from our study population, are uploaded to multi-layered artificial neuralnetwork and the network was trained by genetic algorithm.Results: Trained cluster consists of 14 factors (7 atrial septal defect and 7 ventricular septal defect). Overall success ratio is 79.2%, andwith a proper instruction of artificial neural network this ratio increases up to 89%.Conclusion: Parameters, belonging to artificial neural network, which are needed to be detected by the investigator in classical methods,can easily be detected with the help of genetic algorithms. During the instruction of artificial neural network by genetic algorithms, boththe topology of network and factors of network can be determined. During the test stage, elements, not included in instruction cluster, areassumed as in test cluster, and as a result of this study, we observed that multi-layered artificial neural network can be instructed properly,and neural network is a successful method for aimed classification.

Cardiac tamponade is a life-threatening condition requiring urgent intervention. It may either be drained surgically or percutaneously. Percutaneous drainage of pericardial effusion bears the risk of laceration and perforation of the myocardium and the coronary vessels, air embolism, pneumothorax, dysrhythmias, puncture of the peritoneal cavity and abdominal viscera, internal mammary artery fistula, acute pulmonary edema, and purulent pericarditis. Here, we report an easy and safe approach for pericardiocentesis under the guidance of agitated saline contrast injection through a Seldinger needle before inserting guidewire and catheter. This cheap, easy, feasible, and comfortable method of injection of agitated saline contrast before the insertion of guidewire and catheter may prevent the undesired complications.
