F.; Yilmaztepe, M. A.; Taylan, G.; Altay, S.Aims: This study aims to review the influence of gender-specific differences and patient demographics on cardiac device and pacing mode selection over a 10-year period. Methods: We retrospectively reviewed patients who underwent first implantation of the cardiac device between January 1, 2006 and June 31, 2016. Results: During the study period, 704 patients underwent first cardiac device implantation. Number of patients undergoing pacemaker was 452 and number of patients undergoing implantable cardioverter defibrillator/cardiac resynchronization therapy and defibrillator (ICD/CRT-D) was 252. Patients undergoing pacemaker were 49.9% female with mean age 72.36+11.1. The most common indication was atrioventricular block (AVB) (84%) in both genders. The most frequently used pacing modes were VVI (70.8%), but over a 10-year period pacemaker selection shifted from VVI to DDD pacemakers. Patients undergoing ICD/CRT-D were 19.7% female with mean age 62.5+10.8. The most common indications for ICD/CRT-D was ischemic cardiomyopathy (ICMP) (55.0%). The rate of male patients was higher in patients who have received device therapy for dilated cardiomyopathy (DCMP) or ICMP, whereas the rate of female patients was higher in hypertrophic cardiomyopathy (HCMP) patients. The most common used implanted system was VVI-ICD (60.6%). Conclusions: The present study demonstrated that there was no significant difference between female and male patients in pacing mode selection, mostly VVI pacing mode was chosen; however, over a 10-year period pacemaker selection shifted from VVI to DDD pacemakers. Female patients had less ICD/CRT-D implantation than male patients.Öğe PERICARDITIS RELATED THROMBOTIC THROMBOCYTOPENIC PURPURA(Elsevier Ireland Ltd, 2011) Barutcu, A.; Aktoz, M.; Altun, A.; Alicik, G.[Abstract Not Available]Öğe Pulmonary microvascular permeability and gas exchange in patients with syndrome X(Lithographia, 2012) Durmus-Altun, G.; Vardar, S. A.; Salihoglu, Y. S.; Aktoz, M.; Dirlik, B.; Altun, A.Aim: This clinical study was planned to assess pulmonary microvascular permeability in patients with Syndrome X (SX) by using a functional imaging tool, technetium-99m-diethyltriaminepentaaceticacid (Tc-99m-DTPA) lung clearance scintigraphy, and the pulmonary functions test, which includes diffusion capacity of the lung for carbon monoxide (DLCO). Methods: The study population consisted of 22 non-smoker subjects divided into two groups. First group comprised 12 patients (4 male, 8 female, mean age: 48 +/- 4 years, range 36 to 65) with SX. Ten healthy subject (4 men, 6 female, mean age: 45 +/- 3 years, range 34 to 58) were served as control group. Volumetric pulmonary functions, including DLCO were also performed before lung scintigraphy. Alveolar epithelial permeability was assessed by measuring the pulmonary clearance of an inhaled Tc-99m-DTPA using a gamma camera. Results: Spirometric data was comparable in both groups. Although volumetric pulmonary measurements were similar, DLCO values of SX patients were lower than those in control (20.9 +/- 1.7 ml/min/mmHg vs. 27.8 +/- 1.3 ml/min/mmHg, p=0.002). The mean clearance rate of Tc-99m-DTPA in control subjects was 106 +/- 6 min, and this value was lower than patients with SX (179 +/- 19 min; p=0.0001). Conclusion: We conclude that lung is a target organ for SX. The pulmonary gas exchange and microvascular permeability, which is measured by 99mTc-DTPA scintigraphy, are restricted without change of volumetric pulmonary functions in patients with SX. Hippokratia 2012; 16 (2): 113-117Öğe A retrospective study of angiographically determined anomalous coronary arteries in 12,844 subjects in Thrace region of Turkey(Lithographia, 2012) Sivri, N.; Aktoz, M.; Yalta, K.; Ozcelik, F.; Altun, A.Background: Congenital anomalies of the coronary arteries are rarely encountered in patients undergoing cardiac catheterization. In patients undergoing coronary angioplasty or cardiac surgery, angiographic recognition of coronary anomalies is important for the proper management of these patients. Method: We retrospectively reviewed the records of 12,844 patients who had previously undergone coronary angiography in the catheterization laboratory of Trakya University Cardiology Department over the past 14 years. We tried to investigate the presence of a variety of coronary anomalies in these patients to determine the prevalence of various types of anomalies and their anatomic variation in a selected population of the European part of Turkey. The potential association between coronary atherosclerosis and congenital coronary anomalies was also investigated. Results: Among these patients, 95 patients were found to have major coronary anomalies that predominantly comprised anomalous aortic origin of coronary arteries. Among the major anomalies, anomalous aortic origin of the left circumflex (LCX) artery from the right sinus of Valsalva or right coronary artery (RCA) was found to be the the most prevalent (46 out of 95 patients) outnumbering the second most common anomaly that was anomalous aortic origin of the RCA (32 out of 95 patients). In the present study, the incidence of major coronary arterial anomaly was found to be 0.74 %. However, only about one third of the patients (31 out of 95, 32.6%) with major anomaly had significant coronary atherosclerotic lesions among whom nine were found to involve the LCX artery with a posterior course. Conclusion: The incidence of congenital coronary anomalies in a selected population of the European part of Turkey is similar to those of other populations. Congenital coronary anomalies generally present as isolated anomalies and are not associated with an increased risk of coronary atherosclerosis in this series. Cardiologists and surgeons should be familiar with these entities for the proper management of patients undergoing cardiac surgery or coronary angioplasty.
