OBJECTIVES Dissipative energy loss derived from vector flow mapping represents the viscous dissipation of turbulent blood flow. We aimed to determine the left ventricular (LV) energy loss in patients with end-stage renal disease (ESRD). METHODS Patients with ESRD and a preserved LV ejection fraction, who consisted of a group receiving peritoneal dialysis,(More)
Atrial septal defect (ASD) is a common type of congenital heart disease, which is defined as any communication through atrial septum. Several studies have revealed that genetic factors may influence the susceptibility of ASD. Recent studies have shown that reticulon 4 (RTN4) gene might be involved in some processes relevant to heart development, such as(More)
We report a case of a 52-year-old patient with dilated cardiomyopathy who presented with worsening heart failure. Two-dimensional transthoracic echocardiography and real-time three dimensional transthoracic echocardiography showed severe dilated cardiac chambers, impaired ejection fraction and a mobile right atrial thrombus 2.6 × 1.0 cm in size, traversing(More)
We sought both to evaluate the clinical value of transesophageal echocardiography in minimally invasive surgical closure of ventricular septal defects and to evaluate the feasibility, safety, and efficacy of the surgical occlusion procedure. We selected 49 pediatric patients who had perimembranous ventricular septal defects as determined by preoperative(More)
In this paper, we propose a geometric features extraction approach for RGB-D image and its application in intrinsic scene properties recovery. Our approach extracts geometric features, and make use of both 3D shape information from depth map and edge information from RGB image. Geometric features are categorized as occlusion edges and fold edges. The(More)
OBJECTIVES In nonvalvular atrial fibrillation (NVAF) patients, the effect of left atrial appendage (LAA) morphology, structure, and hemodynamic characteristics evaluated by real-time 3D transesophageal echocardiography (RT3D-TEE) on thromboembolic risk has not been elucidated. METHODS A total of 444 NVAF patients who underwent clinically indicated(More)
The aim of our study was to investigate the potential association of mRNA expression and plasma levels of the LIM domain 7 (LMO7) gene with the pathogenesis of dilated cardiomyopathy (DCM). Two SNPs of the LMO7 gene were genotyped in 310 patients with DCM and 415 controls. Our results showed that SNP rs7986131 (p = 0.002, OR = 1.38, 95% CI = 1.12-1.71), but(More)
The present study aimed to investigate the impact of hypothyroidism on left ventricular systolic function using real-time three-dimensional speckle tracking imaging (RT3D-STI). Thirty hypothyroidism patients and forty healthy volunteers were recruited and received RT3DSTI measurement of global longitudinal strain (GLS), global circumferential strain (GCS),(More)
The aims of this study were i) to evaluate mitral and aortic annuli excursion, and aortomitral angle (AMA) during the cardiac cycle in healthy adults using two-dimensional speckle tracking echocardiography, ii) to assess two annuli dynamics and coupling behaviors as an integral, and iii) to detect the relation between two annuli and left ventricular(More)
