Publication Metadata only Gender Differences in the Types and Frequency of Coronary Artery Anomalies(2011-12-01T00:00:00Z) AYDAR, YÜKSEL; Yazici, Huseyin U.; Birdane, Alparslan; Nasifov, Muharrem; Nadir, AYDIN; ULUS, TANER; Goktekin, Omer; GÖRENEK, BÜLENT; Unalir, Ahmet; NADİR, AYDINCoronary artery anomalies are rarely encountered in general population. Gender may play a role in the types and incidence of coronary artery anomalies, although the effect of gender is not well established. In the present study, we therefore aimed to investigate the frequency and location of various types of coronary artery anomalies and their correlation with gender. We assessed retrospectively the coronary angiography movies of 7,810 patients (2,214 females and 5,596 males), the method of which is distinct from the earlier studies with angiographic archive records. We defined and classified the coronary artery anomalies according to their origin, course (myocardial bridge), and termination (fistula). The incidence of coronary artery anomalies was 3.35% (262 of 7,810): 130 individuals with anomalous origin (1.66%), 105 individuals with myocardial bridges (1.34%), and 27 with fistulas (0.35%). The frequency of the coronary artery anomalies was significantly higher in the females than the males (p = 0.001). Of the coronary artery origin anomalies, the circumflex and the left anterior descending artery originating from separate ostia in the left aortic sinus were higher in the females compared to the males (P < 0.001). In contrast, the frequency of myocardial bridges was higher in the males (P = 0.01). No gender difference was detected in fistulas. Thus, gender affects the types of coronary artery anomalies, except for fistulas. The determination of the presence of the coronary artery anomalies during the coronary angiography is critical for the planning of the treatment and for the proper clinical follow-up of patients.Publication Open Access The prognostic value of fragmented QRS in patients undergoing transcatheter aortic valve implantation(2018-11-01) Ay, Nuray Kahraman; ENHOŞ, ASİM; AY, YASİN; Ozdemir, Razaman; NADİR, AYDIN; KARAÇÖP, ERDEM; ÇELİKKALE, İLKE; ULUGANYAN, MAHMUT; Goktekin, Omer; KAHRAMAN AY, NURAY; ENHOŞ, ASIM; AY, YASİN; BAKHSALIYEV, NIJAD; NADİR, AYDIN; KARAÇÖP, ERDEM; ÇELİKKALE, İLKE; ULUGANYAN, MAHMUT; ÖZDEMİR, RAMAZANBackground Although transcatheter aortic valve implantation (TAVI) can successfully correct aortic narrowing, pre-existing pathophysiological alterations in the left ventricle are still a concern in terms of long-term mortality. This study aimed to examine the predictive role of fQRS morphology on long-term prognosis in patients undergoing TAVI due to severe aortic stenosis. Methods A total of 117 patients undergoing TAVI due to severe aortic stenosis were included in this retrospective cohort study. Patients were assigned into two groups based on the presence (n = 36) or absence (n = 81) of fQRS. Predictors of long-term survival were estimated. Results In-hospital mortality was higher in fQRS group (5.5% vs. 1.2%, p = 0.0224). In the long-term, fQRS (OR: 3.06, 95% CI 1.29–7.27, p: 0.01), LVEF <50% (OR: 2.54, 95% CI 1.07–6.02, p: 0.03) and presence of atrial fibrillation (OR: 2.42, 95% CI 1.05–5.60, p: 0.03) emerged as significant independent predictors of short survival. Conclusion Presence of fQRS on ECG, an indirect indicator of myocardial fibrosis, seems to have the potential to be used as a prognostic marker after TAVI procedure. Large prospective studies are warranted.Publication Metadata only Relationship between significant coronary artery disease and coronary artery anomalies(2013-01-01T00:00:00Z) BİRDANE, ALPARSLAN; Yazici, Huseyin Ugur; AYDAR, YÜKSEL; Nadir, AYDIN; Senol, Utku; Tasal, Abdurrahman; Goktekin, Omer; ATA, NECMİ; NADİR, AYDINAim: In the present study we aimed to investigate the frequency and types of coronary artery anomalies (CAAs) and their correlation with coronary artery disease (CAD).
