The CD133(+) bone marrow cell (BMC) population includes primitive multipotent stem cells which induce neoangiogenesis. Studies suggested transplantation of these cells to infarcted myocardium can have a favorable impact on tissue perfusion and contractile performance. We assessed the feasibility, safety and functional outcomes of autologus CD133(+) BMC(More)
BACKGROUND Transcatheter closure of atrial septal defect secundum (ASD-II) has become an alternative method for surgery. We sought to compare the two-dimensional transesophageal echocardiography (TEE) method for measuring atrial septal defect with balloon occlusive diameter (BOD) in transcatheter ASD-II closure. METHODS A total of 39 patients (71.1%(More)
BACKGROUND Many previous studies have evaluated the impact of mitral valve (MV) deformity scores on the percutaneous transvenous mitral commissurotomy (PTMC) outcome in patients with mitral stenosis; however, the relationship between mitral annulus calcification (MAC) and the PTMC result has not yet been established. The current study aimed to investigate(More)
BACKGROUND Left ventricular (LV) dyssynchrony is a prevalent feature in heart failure (HF) patients. The current study aimed to evaluate the prevalence of inter and intraventricular dyssynchrony in HF patients with regard to the QRS duration and etiology. METHODS The available data on the tissue Doppler imaging (TDI) of 230 patients with refractory HF(More)
Background: It is not clear whether the latest activation sites in the left ventricle (LV) are matched with infracted regions in patients with ischemic cardiomyopathy (ICM). We aimed to investigate whether the latest activation sites in the LV are in agreement with the region of akinesia in patients with ICM. Methods: Data were analyzed in 106 patients (age(More)
BACKGROUND Cardiomyopathies are myocardial disorders in which the heart muscle is structurally and functionally abnormal. Several mutations in sarcomere protein coding genes are responsible for different types of cardiomyopathies. ACTC1 is one of the main sarcomere components in heart muscle. Two mutations of E101K and M123V in this gene are shown to be(More)
BACKGROUND Several competing geometric and hemodynamic factors are suggested as contributing mechanisms for functional mitral regurgitation (MR) in heart failure patients. We aimed to study the relationships between the severity of MR and the QRS duration and dyssynchrony markers in patients with ischemic or dilated cardiomyopathy. METHODS We(More)
BACKGROUND Several echocardiographic markers have been introduced to assess the left ventricular (LV) mechanical dyssynchrony. We studied dyssynchrony markers and the latest LV activation site in heart failure patients with and without left bundle branch block (LBBB). METHODS Conventional echocardiography and tissue velocity imaging were performed for 78(More)
OBJECTIVES Transcatheter closure of a secundum atrial septal defect (ASD II) has become an effective alternative for surgical treatment. In this study we evaluated the correlation between the two-dimensional transoesophageal echocardiographic (2D TEE) sizing of ASDs and the actual diameter of occluders in patients undergoing device closure. METHODS The(More)
BACKGROUND The location of acute myocardial infarction (MI) is an important prognostic factor for risk stratification of patients with first ST-segment elevation MI (STEMI). The main goal of this study was to compare the severity and extension of coronary involvement in inferior and anterior MI. METHODS This study reviewed angiographic reports of 579(More)
