- Commercial 4-dimensional echocardiography for murine heart volumetric evaluation after myocardial infarctionPosted by Cody Rutledge, George Cater, Brenda McMahon, Lanping Guo, Seyed Mehdi Nouraie, Yijen Wu, Flordeliza Villanueva and Brett A. Kaufman on March 12, 2020 at 12:00 am
Traditional preclinical echocardiography (ECHO) modalities, including 1-dimensional motion-mode (M-Mode) and 2-dimensional long axis (2D-US), rely on geometric and temporal assumptions about the heart for volu... […]
- Echocardiographic evidence of left ventricular untwisting-filling interplayPosted by Amir Hodzic, Damien Garcia, Eric Saloux, Paula A. B. Ribeiro, Amélie Ethier, James D. Thomas, Paul Milliez, Hervé Normand and Francois Tournoux on February 19, 2020 at 12:00 am
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 u... […]
- Global peak left atrial longitudinal strain assessed by transthoracic echocardiography is a good predictor of left atrial appendage thrombus in patients in sinus rhythm with heart failure and very low ejection fraction – an observational studyPosted by Jacek Kurzawski, Agnieszka Janion-Sadowska, Lukasz Zandecki, Lukasz Piatek, Dorota Koziel and Marcin Sadowski on February 15, 2020 at 12:00 am
Peak left atrial longitudinal strain (PALS) can help identify left atrial appendage thrombus (LAAT) in patients with atrial fibrillation. Nevertheless, few studies have been performed in patients in sinus rhyt... […]
- Incremental value of three-dimensional echocardiography for evaluating left atrial function in patients with coronary slow flow phenomenon: a case control studyPosted by Jun Li, Yonghuai Wang, Cuiting Zhao, Qing Zhu, Guangyuan Li, Jun Yang, Dalin Jia and Chunyan Ma on February 13, 2020 at 12:00 am
Coronary slow flow phenomenon (CSFP) involves the delayed opacification of the coronary distal vessel, in the absence of an obstructive lesion in the epicardial coronary artery during angiography. Since the li... […]
- The impact of different geometric assumption of mitral annulus on the assessment of mitral regurgitation volume by Doppler methodPosted by Wugang Wang, Zhibin Wang, Junfang Li, Kun Gong, Liang Zhao, Guozhang Tang and Xiuxiu Fu on January 31, 2020 at 12:00 am
Mitral regurgitation volume (MRvol) by quantitative pulsed Doppler (QPD) method previously recommended suffers from geometric assumption error because of circular geometric assumption of mitral annulus (MA). T... […]
