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)
Coronary artery fistulae are rare disorders. Only 2 reports in the medical literature discuss the use of vascular plugs to occlude coronary fistulae, and the same device-the Amplatzer Vascular Plug-was deployed via different techniques to treat those patients. The safety, the feasibility, and the standard approach to deployment have yet to be established.(More)
BACKGROUND Echocardiographic measurements of time-to-peak systolic velocities (Ts) are helpful for assessing the degree of cardiac asynchrony. We assessed the degree of ventricular asynchrony in structurally normal heart according to Ts by tissue Doppler imaging. METHODS We performed conventional echocardiography and tissue velocity imaging for 65 healthy(More)
In 258 patients with left main tract disease, the atherosclerotic risk factors were compared between patients with ostial and nonostial lesions of the left main coronary artery. Also, it was done for patients with ostial right coronary artery. Women were more likely to have ostial left main coronary artery and/or ostial right coronary artery. A multivariate(More)
OBJECTIVES To quantify the normal peak mean systolic velocities and strain rate parameters in the left ventricle (LV) and right ventricle (RV) and define their regional differences in normal adult hearts. METHODS Sixty-nine healthy volunteers (42% male; mean age ± SD, 30.03 ± 5.35 years) underwent color tissue Doppler and strain rate imaging. The first(More)
BACKGROUND The implantation of a CD133+ bone marrow cell population into an ischemic myocardium has emerged as a promising therapeutic modality for myocardial regeneration and restoration of ventricular contractility. While previous studies have documented the short-term safety and efficacy of CD133+ cell transplantation in patients with acute myocardial(More)
OBJECTIVES It is not clear whether the presence and degree of chronic ischemic mitral regurgitation (IMR) in patients with left ventricular (LV) dysfunction are related to LV dysfunction, local LV remodeling or mitral valve deformation. We sought to establish the strongest determinants of IMR severity in patients with LV dysfunction and IMR. METHODS We(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 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 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)
