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 Metadata only Effects of levosimendan and dobutamine on systolic time intervals in patients with acute decompensated heart failure(2013-05-01T00:00:00Z) ÇAVUŞOĞLU, YÜKSEL; Nadir, AYDIN; MERT, KADİR UĞUR; Gencer, E.; MUTLU, FEZAN; ULUS, TANER; NADİR, AYDINPublication Metadata only Ivabradine treatment prevents dobutamine-induced increase in heart rate in patients with acute decompensated heart failure(2015-09-01T00:00:00Z) ÇAVUŞOĞLU, YÜKSEL; MERT, KADİR UĞUR; Nadir, AYDIN; MUTLU, FEZAN; Morrad, Bektas; ULUS, TANER; NADİR, AYDINBackground Ivabradine is a heart rate (HR)-lowering agent acting by inhibiting the I-f-channel. Dobutamine does increase the HR and has some deleterious effects on myocardium. So, we aimed to evaluate whether ivabradine treatment blunts a dobutamine-induced increase in HR.Publication Metadata only Native mitral valve causing left ventricular outflow tract obstruction in an adult with Ebstein-s anomaly(2011-11-01T00:00:00Z) ULUS, TANER; Nadir, AYDIN; Birdane, Alparslan; ATA, NECMİ; NADİR, AYDINPublication Metadata only Ivabradine treatment blunts dobutamine-induced increase in heart rate in patients with acute decompensated heart failure: a comparative study with beta-blocker therapy(2013-05-01T00:00:00Z) ÇAVUŞOĞLU, YÜKSEL; MERT, KADİR UĞUR; Nadir, AYDIN; MUTLU, FEZAN; Gencer, E.; ULUS, TANER; NADİR, AYDINPublication Metadata only Left anterior descending coronary artery originating from the distal right coronary artery: a previously unreported coronary artery anomaly(2012-01-01T00:00:00Z) Yazici, H.

It can be asymptomatic or cause myocardial infarction (MI). In this case we present a 53-year old man hospitalized with MI within one month after CABG and detected to have SVG aneurysms. He had triple CABG (one of them was internal mammarian artery, two of them were SVG) one month ago. His grafts were open and no thrombotic occlusion was detected in native vessels or grafts in control coronary angiography. In addition, the diameters of SVGs were aneurysmatic and a thrombus was detected within one. No cardiac event has developed over the six months of follow-up in the patient who was discharged after initiation of Warfarin therapy. In conclusion, SVG aneurysm may cause MI not related to thrombotic occlusion in the early period after CABG.

Previous studies have demonstrated accumulation of PEX material in the walls of blood vessels and myocardium. We aimed to investigate whether PEX is associated with cardiovascular involvement using carotid ultrasound measurements and myocardial tissue Doppler imaging (TDI).MethodsThirty-six PEX patients and 34 age-matched and sex-matched healthy controls who had no PEX material were included. Fasting blood samples were taken and the following data were obtained from all cases: myocardial TDI measurements, the mean carotid intima-media thickness (IMT), total carotid plaque area and number.ResultsThere were no significant differences between the groups regarding clinical and biochemical data. The peak systolic TDI velocities at the septal (septal S) and lateral annuli (lateral S), and the isovolumic contraction velocity at the lateral annulus [lateral isovolumic contraction velocity (IVC)] were significantly lower in patients with PEX, than in controls (P=0.001, <0.001 and 0.016, respectively) whereas IMT, total carotid plaque area and number were significantly higher (P=0.002, 0.035 and 0.033, respectively). In a logistic regression analysis including age, septal S, lateral S, lateral IVC, IMT, total carotid plaque area and number, septal S, lateral S and IMT were significantly associated with PEX, (P=0.035, 0.011 and 0.035, respectively).ConclusionPeak systolic TDI velocities were significantly lower and IMT was significantly increased in patients with PEX. However, PEX was weakly associated with carotid plaque measurements.
