BACKGROUND The aim of this study was to assess the impact of hypertension with or without diabetes on left ventricular (LV) remodeling in rural Chinese population. METHODS A total of 10,270 participants were classified into control group, hypertension without diabetes (HT) group, and hypertension with diabetes (HT + DM) group. We compared clinical characteristics and echocardiographic paramet...

A congenital coronary artery fistula (CCAF) combined with giant aneurysm (CAA) is a rare cardiac abnormality. We reported an 8-year-old patient who underwent transcatheter closure of both inlet and outlet proximal left (LCA)-to-left ventricular (LV) CAA 41 mm × 28 in diameter, during which acute occlusion anterior descending (LAD) occurred immediately after device implantation at the fistula. m...

Background Rheumatoid arthritis (RA) is associated with increased incidence of cardiovascular disease (CVD) and heart failure (HF) compared to the general population. CMR studies in the general population demonstrate that increases in left ventricular (LV) mass and early LV structural changes are predictors of HF in asymptomatic patients. Previous studies have reported conflicting data on LV ge...

  Introduction: Although left ventricular(LV) function parameters measured by gated myocardial perfusion SPECT (GSPECT) have been validated, experimental data have revealed that the calculated the LV function parameters using GSPECT are affected by patient populations as well as particular acquisition and processing conditions. We tried to determine the normal values ...

The effects of alterations in the diastolic filling pressure of the right ventricle on left ventricular (LV) geometry and filling pressure were studied in six isolated, supported canine hearts. This experimental preparation permitted graded increments in right ventricular (RV) end-diastolic pressure while LV cardiac output, heart rate, and mean aortic pressure were held constant. Endocardial ra...

A 29 year-old male without any risk factors for coronary artery disease presented with symptomatic sustained ventricular tachycardia. 2-Dimensional (2D) Transthoracic Echocardiogram (TTE) did not reveal any abnormality. When we did a 3-Dimensional (3D) echocardiogram, a small Left Ventricular (LV) aneurysm was detected near the outflow tract. After catheter ablation, the patient was discharged ...

Introduction Left ventricular (LV) twist is believed to store potential energy and plays an important role in generating diastolic suction. Recent advances in echocardiography techniques have allowed quantification of LV twist. The aim of the present study was to compare LV twist and torsion in healthy human subjects determined by velocity vector imaging (VVI) and tissue Doppler imaging (TDI) a...

Background—Expansion of an acute myocardial infarction predicts progressive left ventricular (LV) dilatation, functional deterioration, and early death. This study tests the hypothesis that restraining expansion of an acute infarction preserves LV geometry and resting function. Methods and Results—In 23 sheep, snares were placed around the distal left anterior descending and second diagonal cor...

to evaluate the prognostic significance of clinicopathological measurement in the diagnosis of acute myocardial infarction (mi) in sheep, acute mi was induced by ligation of left anterior descending coronary artery (lad). for this purpose, twenty four healthy sheep were divided into the sham-operated or control group (group i, thoracotomy without mi) and the experimental group (group ii, with m...
