Left atrial function in uraemic patients: Four‐dimensional automatic left atrial quantitative technology study

ESC Heart Failure, Volume 12, Issue 2, Page 1316-1325, April 2025.
Abstract Objective This study aimed to evaluate the utility of left atrial volume and function in uraemic patients using four‐dimensional automatic left atrial quantification (4D auto LAQ) technology. Methods Thirty‐four undialysed uraemic patients (U‐ND group), 60 dialysed uraemic patients (U‐D group), and 32 healthy volunteers (N group) were enrolled

Assessment of Regional Myocardial Displacement via Spectral Tissue Doppler Compared with Color Tissue Tracking [PDF]

Journal of Tehran University Heart Center, 2008
Background: The recent developments in tissue Doppler imaging (TDI) now more than ever permit the quantification of the myocardial function. In the current systems, tissue tracking or displacement curves are generated from color tissue Doppler data ...

Multiple coronary artery-left ventricular microfistulae in a patient with apical hypertrophic cardiomyopathy: a demonstration by transthoracic color Doppler echocardiography.

Yonsei medical journal, 2003
Among the congenital coronary artery fistulae, multiple coronary artery microfistulae arising from the left and right coronary artery and emptying into the left ventricle are very rare and little is known of their anatomic and clinical features ...

Echocardiographic evidence of left ventricular untwisting-filling interplay

Cardiovascular Ultrasound, 2020
Background Left ventricular untwisting generates an early diastolic intraventricular pressure gradient (DIVPG) than can be quantified by echocardiography. We sought to confirm the quantitative relationship between peak untwisting rate and peak DIVPG in a
