Öğe Arterial myocardial revascularization using bilateral radial artery - 17 years after right pneumonectomy(Texas Heart Inst, 2004) Erdil, N; Nisanoglu, V; Toprak, HI; Erdil, FA; Kuzucu, A; Battaloglu, BWe report the case of a 51-year-old man who underwent arterial myocardial revascularization with the use of bilateral radial arteries, 17 years after undergoing a right pneumonectomy. We used a fast-track anesthesia protocol for the procedure. There was no perioperative complication, and postoperative recovery was uneventful. The patient was discharged from the hospital 5 days after the operation.Öğe A case of left atrial myxoma associated with atrial septal defect(Wiley, 2005) Kosar, F; Erdil, N; Gullu, H; Sahin, I; Nisanoglu, V; Battaloglu, BCardiac myxoma is the most frequent primary tumor of the heart. However, it is rarely associated with congenital cardiac anomalies such as atrial septal defect in the literature. We present a 72-year-old woman referred to the emergency department with loss of consciousness and finally diagnosed as a pedinculated mobile left atrial myxoma and concomitant occurrence of an ostiurn secundum type atrial septal defect. The mass was successfully excised, and atrial septal defect was safely repaired by primary suture, The patient is currently well after surgery. Atrial myxoma should be considered in the differential diagnosis when patients present with neurological consequences of systemic embolization.Öğe Complete left-sided absence of the pericardium in association with buptured type A aortic dissection complicated by severe left hemothorax(Texas Heart Inst, 2005) Nisanoglu, V; Erdil, N; Battaloglu, BWe report an unusual clinical presentation of an acute type A aortic dissection as a left hemothorax in a patient with a congenital pericardial defect. Although the pericardial defect was diagnosed preoperatively, we could not exclude the possibility of a ruptured descending aorta until we discovered the site of the rupture during operation. The presence of a pericardial defect would at first appear to be a fatal disadvantage in such a situation as this, due to massive bleeding into the pleural space; but we believe that in our patient spontaneous drainage of blood into the pleural cavity prevented severe cardiac tamponade. The only reason for his deteriorating hemodynamic status was hypovolemia, which was corrected with volume replacement.Öğe Does cardiopulmonary bypass alter plasma level of tumor markers? CA 125 and carcinoembryonic antigen(Georg Thieme Verlag Kg, 2002) Battaloglu, B; Kaya, E; Erdil, N; Nisanoglu, V; Kosar, F; Ozgur, B; Yildirim, BBackground: In addition to malignant diseases, acute and chronic inflammations may elevate plasma levels of tumor markers CA 125 and carcinoembryonic antigen (CEA). Cardiopulmonary bypass (CPB) causes a generalized inflammatory response. In this study, we have investigated the effect of CPB on plasma levels of CA 125 and CEA. Methods: We measured plasma levels of CA 125 and CEA in patients undergoing coronary artery bypass grafting (CABG) with CPB (Group 1, n = 21), and in patients who underwent off-pump CABG, that is, without CPB (Group 2, n = 16). Blood samples were collected preoperatively, and on postoperative days 1, 6, and 12. Results: Within both groups, CEA plasma levels were not significantly influenced in any samples. Comparing with preoperative values, CA 125 values elevated significantly on postoperative days 6 and 12 within both groups. It was observed that the elevation of CA 125 plasma levels in these samples were significantly higher in Group 1. Conclusions: The results indicate that CPB elevated plasma level of CA 125. However, clinical importance of this finding needed further evaluation.Öğe Effect of posterior pericardiotomy on early and late pericardial effusion after valve replacement(Blackwell Publishing, 2005) Erdil, N; Nisanoglu, V; Kosar, F; Erdil, FA; Cihan, HB; Battaloglu, BObjective: Pericardial effusion (PE) after cardiac surgery is frequent. It is more frequently seen after valve replacement or other types of heart surgery. Oral anticoagulants and antiplatelet agents may induce effusion development after open heart surgery. Our objective was to determine the efficiency of posterior pericardiotomy (PP) after cardiac valve operation for reducing the incidence of early and late PE and tamponade. Methods: This prospective randomized study was carried out in 100 consecutive patients undergoing mechanical valve replacement between August 2001 and May 2003 in our institution. Patients were divided into two groups; each group consisted of 50 patients. Longitudinal incision was made parallel and posterior to the left phrenic nerve, extending from the left inferior pulmonary vein to the diaphragm in Group 1. Posterior pericardiotomy was not done in Group 2. Results: Early PE was detected in four patients (8%) and in 19 patients (38%) in Group 1 and Group 2, respectively (p < 0.001). No late PE effusion was developed in Group 1 despite nine (18%) late PE developing in Group 2 (p < 0.003). The rate of delayed pericardial tamponade was lower in Group 1, but this difference was not statistically significant (0% vs 10%; p < 0.056). Conclusion: These findings suggest that PP is an easy, feasible, and beneficial technique for reducing both the occurrence of early and late PE or pericardial tamponade in patients undergoing valve replacement.Öğe Effects of coronary revascularization and concomitant aneurysmectomy on QT interval duration and dispersion(Churchill Livingstone Inc Medical Publishers, 2006) Kosar, F; Nisanoglu, V; Aksoy, Y; Colak, C; Erdil, N; Battaloglu, BA reduction in QT dispersion (QTd) has been previously shown in patients receiving thrombolytics and undergoing coronary artery bypass grafting (CABG). The purpose of the present study was to investigate changes occurring in corrected QT intervals or QT dispersion after CABG and concomitant aneurysmectomy in the same session. The study population included 43 patients with coronary artery disease with left ventricular aneurysm (LVA). The control group included 32 patients with coronary artery disease without LVA. The study patients underwent CABG and aneurysmectomy in the same surgical session. Corrected maximum and minimum QT interval duration (QTcmax and QTcmm) and corrected QT dispersion (QTcd) were measured in the study patients before and after surgery. QTcmax and QTcd in the patients with LVA were significantly higher than in the patients without LVA (P < .001 and P < .001, respectively). QTcmax and QTcd in the patients with LVA were significantly shortened after surgery (P < .001 and P < .001, respectively). This study showed that QTcmax and QTcd values are significantly reduced after CABG and concomitant aneurysmectomy. We have suggested that coronary revascularization and left ventricular reconstruction in the same session have beneficial effects on QT interval duration and dispersion.
