BACKGROUND quantitative assessment and validation of left ventricular (LV) volumes and mass in neonates and infants with complex congenital heart disease (CHD) is important for clinical management but has not been undertaken. We compared matrix-array 3D echocardiography (3D echo) measurements of volumes, mass, and ejection fraction (EF) with those measured by cardiac MRI in young patients with ...

BACKGROUND Myocardial infarct scars are usually imaged by delayed-enhanced cardiac magnetic resonance (DE-cMR). In this study, we tested the hypothesis that the detection and quantification of myocardial scars can be evaluated by 3D echocardiography (3D-echo). METHODS AND RESULTS Fifty patients with a healed myocardial infarction (>3 months) and 10 controls underwent 3D echo and DE-cMR within...

gestational choriocarcinoma usually occurs following an intrauterine pregnancy. we report a case of metastatic choriocarcinoma to the left kidney and lungs with long term intermittent amenorrhea and vaginal bleeding after a normal vaginal delivery. a 43 year old rural woman presented with three years intermittent amenorrhea and vaginal bleeding following normal vaginal delivery. she also compla...

We compared the follow-up data on loop diuretic use and renal function, as assessed by serum creatinine levels, and the estimated glomerular filtration rate (eGFR), of two groups of consecutive ambulatory HF patients: 1) the clinically-guided group, in which management was clinically driven based on the institutional protocol of the HF Unit of the Cardiovascular and Thoracic Department of Pisa ...

An accurte echocardiographic (E) method for determination of left ventricular mass (LVM) was derived from systematic analysis of the relationship between the antemortem left ventricular echogram and postmortem anatomic LVM in 34 adults with a wide range of anatomic LVM (101-505 g). No subject had massive myocardial infarction, ventricular aneurysm, severe right ventricular volume overload or hy...

Introduction: A theoretical MR model has been proposed that separately quantifies dispersed (soluble, ferritin-like) and aggregated (insoluble, hemosiderin-like) iron by distinguishing their effects on R2 relaxation curves. Recently, this model has been validated in agarose phantoms using MnCl2 and iron oxide microspheres to mimic ferritin and hemosiderin iron, respectively. Here, we directly m...

This investigation examined the anabolic-hormone response to carbohydrate (CHO) supplementation at rest and after resistance exercise. Nine recreationally trained men randomly underwent 4 testing conditions: rest with placebo (RPL), rest with CHO (RCHO), resistance exercise with placebo (EPL), and resistance exercise with CHO (ECHO). The resistance-exercise protocol was four sets of Smith machi...

[1] Smerdon et al. [2008] correctly conclude that the initial regridding method used by Mann et al. [2007] (hereafter M07) to map ECHO-g output to the resolution of surface observation data resulted in enhanced variability of the Northern Hemisphere (NH) mean series compared to the original model output (Figure 1a of Smerdon et al. [2008]). They also correctly conclude that the gridding method ...
