Evaluation of the Effect of Transcatheter Aortic Valve Implantation on Left Ventricular Function by 4-Dimensional Echocardiography.

Objective: Bene���cial e���ects of transaortic valve implantation on left ventricular hemodynamics and prognosis of patients have been demonstrated. Although left ventricular systolic and diastolic function following transaortic valve implantation procedure have been examined in previous studies, 4-dimensional echocardiographic parameters have not been extensively studied, especially in patients with preserved ejection fraction aortic stenosis. In our study, we planned to evaluate the e���ect of transaortic valve implantation on myocardial deformation using 4-dimensional echocardiography.

Relationship between serum homocysteine levels and structural-functional carotid arterial abnormalities in inactive Behçet's disease.

Background: Behçet's disease (BD) is a chronic autoimmune disorder with symptoms manifesting from an underlying vasculitis. Since the disease activity is correlated with characteristic vascular endothelial dysfunction, BD places individuals at increased risk of cardiovascular diseases, such as atherosclerosis. Hyperhomocysteinaemia is an independent risk factor for arteriosclerotic vascular diseases.

Assessment of left atrial volume and mechanical functions using real-time three-dimensional echocardiography in patients with mitral annular calcification.

Objective: Mitral annular calcification (MAC) is degeneration of the fibrous annular ring of the mitral valve. Left atrial (LA) function and volume have been evaluated by many methods; however, none have used real-time three-dimensional echocardiography (RT3DE) in patients with MAC. Our study is the first to evaluate LA volume and mechanical function using RT3DE in patients with MAC.

Evaluation of Electrocardiographic T-peak to T-end Interval in Subjects with Increased Epicardial Fat Tissue Thickness.

Background: The association between periatrial adiposity and atrial arrhythmias has been shown in previous studies. However, there are not enough available data on the association between epicardial fat tissue (EFT) thickness and parameters of ventricular repolarization. Thus, we aimed to evaluate the association of EFT thickness with indices of ventricular repolarization by using T-peak to T-end (Tp-e) interval and Tp-e/QT ratio.

Increased epicardial adipose tissue thickness on transthoracic echocardiography in patients with Behçet disease.

Objectives: Owing to the fact that the potential frequency of endothelial dysfunction and early atherosclerosis might be higher in Behçet disease, characterized by acute and chronic inflammatory attacks, it may lead to impairment in flow-mediated dilatation and an increase in epicardial adipose tissue thickness. Therefore, we aimed to evaluate whether epicardial adipose tissue thickness and brachial artery flow-mediated dilatation as markers of early atherosclerosis and endothelial dysfunction were associated with Behçet disease.

Methods: Thirty-five patients with Behçet disease and 35 healthy volunteers were included in this study.

The effects of Ramadan fasting on heart rate variability in healthy individuals: a prospective study.

Objective: Ramadan fasting is one of the five fundamental rituals of Islam. Heart rate variability (HRV) is an independent predictor of increased mortality of patients with myocardial infarction and congestive heart failure. Although many patients in this region fast once a year, the effects of fasting on the HRV, which has a prognostic significance for patients with myocardial infarction and congestive heart failure, are not known.

Methods: We evaluated 57 patients (mean age: 36.

Assessment of atrial electromechanical delay in patients with polycystic ovary syndrome in both lean and obese subjects.

Aim: Even though polycystic ovary syndrome (PCOS) is characterized by increased inflammatory activity and insulin resistance, there is no clinical data about whether risk of atrial fibrillation are increased in these patients. We aimed to evaluate atrial conduction parameters predicting atrial involvement in this patient group.

Methods: The study population comprised 50 women 18-40 years of age who had been diagnosed with PCOS.

Comparision of pain levels of transradial versus transfemoral coronary catheterization: a prospective and randomized study.

Objective: The aim of the present study was to assess access site pain levels of patients undergoing coronary catheterization via transradial route.

Methods: We performed a prospective and randomized study in which 408 patients underwent coronary angiography (CAG) and/or percutaneous coronary intervention (PCI) via transradial approach (TRA) and 428 patients underwent CAG and/or PCI via transfemoral approach (TFA). Pain levels of patients were assessed with Visual Analog Scale (VAS) after catheterization and at 30 days.

Endothelial nitric oxide synthase levels and their response to exercise in patients with slow coronary flow.

Background: Endothelial dysfunction plays a key role in the aetiopathogenesis of slow coronary flow (SCF) even if there is no obstructive epicardial lesion. Reduced plasma levels of endothelial nitric oxide synthase (eNOS) are an important indicator of endothelial dysfunction. We aimed to determine plasma levels of eNOS and their relationship with exercise in patients with SCF.
