P5614Diagnostic accuracy of echocardiographic estimation of left ventricular filling pressure in a community-hospital setting

Echocardiographic Estimation of Left Ventricular Filling Pressure: Fact or Fiction?*

AORTO-LEFT VENTRICULAR TUNNEL. A CASE REPORT WITH AORTIC PRESSURE AND ECHOCARDIOGRAPHIC FINDINGS

A seven-year-old girl with clinical diagnosis of aortic insufficiency underwent echocardiographic and hemodynamic evaluation and referred for surgery with the same diagnosis. However, at surgery, aorto-Ieft ventricular tunnel was found and repaired successfully. Review of echocardiogram and catheterization data revealed interesting findings to differentiate this rare entity from congenital...

Echocardiographic estimation of left ventricular filling pressures in patients with mitral valve stenosis

BACKGROUND Estimation of left ventricular end-diastolic pressure (LVEDP) among patients with mitral valve disease may help to explain their symptoms. However, conventional Doppler measurements have limitations in predicting LVEDP in this group of patients. The aim of this study was to construct a Doppler-derived LVEDP prediction model based on the combined analysis of transmitral and pulmonary ...

Echocardiographic assessment of left ventricular filling after mitral valve surgery.

In order to investigate the functional effects of mitral valve surgery, echocardiograms showing left ventricular dimension were recorded and digitised in 14 normal subjects and 129 patients after mitral valve surgery. Measurements were made of peak rate of increase of dimension (dD/dt) and duration of rapid filling, studies on left ventriculograms in 36 patients having shown close correlation b...

Accuracy of echocardiographic estimates of left ventricular mass in mice.

Genetically modified mice have created the need for accurate noninvasive left ventricular mass (LVM) measurements. Recent technical advances provide two-dimensional images adequate for LVM calculation using the area-length method, which in humans is more accurate than M-mode methods. We compared the standard M-mode and area-length methods in mice over a wide range of LV sizes and weights (62-21...
