A Simple Doppler Echocardiography Method to Evaluate Pulmonary Capillary Wedge Pressure in Patients with Atrial Fibrillation

Abstract

Measuring E/E' ratio using the one-beat method is a simple and clinically accurate way to estimate wedge pressure in patients with AF.

Early Detection of Drug-Induced Renal Hemodynamic Dysfunction Using Sonographic Technology in Rats

“…Many sonographic studies have focused in cardiac applications; the kidney function assessments were often derived from measurements of cardiac status rather than a direct study of kidney [20][21][22][23][24][25] . We have established an imaging methodology to visualize anatomical and functional changes in kidney in real time.…”

Oznaczenia stężenia peptydów natriuretycznych są częścią diagnostycznej oceny HFpEF [222], ale stężenie peptydów natriuretycznych u pacjentów z AF również jest zwiększone, a optymalna diagnostyczna wartość progowa pozostaje nieznana [235].…”

The Role of Tissue Doppler Imaging in Predicting Left Ventricular Filling Pressures in Patients Undergoing Cardiac Surgery: An Intraoperative Study

“…The ratio of early transmitral filling velocity to the corresponding early mitral annular velocity (E/E′) has been shown to correlate strongly with pulmonary capillary wedge pressure (PCWP) in several studies, including cardiac patients in the nonsurgical setting. [11][12][13][14][15][16][17][18][19][20][21][22] Although previous TTE studies have validated that the ratio of E/E′ < 8 is predictive of normal LVFP (PCWP < 15 mmHg) and E/E′ > 15 is predictive of elevated LVFP (PCWP ! 15 mmHg), [11][12][13][14][15][16][17][18][19][20][21][22] little information exists on the use of transesophageal echocardiography (TEE) for this purpose.…”
