Left ventricular long-axis function in hypertrophic cardiomyopathy - Relationships between e`, early diastolic excursion and duration, and systolic excursion.

Autor: Roger E Peverill, Bon Chou, Lesley Donelan, Wai-Ee Thai

Publikováno v: PLoS ONE, Vol 15, Iss 10, p e0240296 (2020)

BackgroundThe peak velocity of early diastolic mitral annular motion (e`) is believed to provide sensitive detection of left ventricular (LV) diastolic dysfunction in hypertrophic cardiomyopathy (HCM), but other aspects of LV long-axis function in HC

Autor: Wai-ee Thai, Udo Hoffmann, E. Kevin Heist, Michael H. Picard, Jim W. Cheung, Quynh A. Truong, Jagmeet P. Singh, Bryan Wai, Jackie Szymonifka

Publikováno v: Heart Rhythm. 15:1206-1213

BACKGROUND: Dual-source computed tomography (CT) can evaluate left ventricular (LV) dyssynchrony, myocardial scar and coronary venous anatomy in patients undergoing cardiac resynchronization therapy (CRT). OBJECTIVE: We aim to determine if dual-sourc

Myocardial scar imaging by standard single-energy and dual-energy late enhancement CT: Comparison with pathology and electroanatomic map in an experimental chronic infarct porcine model

Autor: Teresa Cheng, Jagmeet P. Singh, Wai-ee Thai, Bryan Wai, Jim W. Cheung, James K. Min, Jonathan Beaudoin, Quynh A. Truong, Guanglei Xiong, Conor D. Barrett, Stephan B. Danik, Kevin Cordaro, Robert K. Altman

Publikováno v: Journal of Cardiovascular Computed Tomography. 9:313-320

Background Myocardial scar is a substrate for ventricular tachycardia and sudden cardiac death. Late enhancement CT imaging can detect scar, but it remains unclear whether newer late enhancement dual-energy (LE-DECT) acquisition has benefit over stan

Publikováno v: Heart Rhythm. 11:2167-2175

A significant minority of patients receiving cardiac resynchronization therapy (CRT) remain nonresponsive to this intervention.This study aimed to determine whether coronary sinus (CS) or baseline peripheral venous (PV) levels of established and emer

Assessment of Mitral Valve Adaptation With Gated Cardiac Computed Tomography

Autor: Robert A. Levine, Mark D. Handschumacher, Jonathan Beaudoin, Bryan Wai, Wai-ee Thai, Quynh A. Truong

Publikováno v: Circulation: Cardiovascular Imaging. 6:784-789

Background— Mitral valve (MV) enlargement is a compensatory mechanism capable of preventing functional mitral regurgitation (FMR) in dilated ventricles. Total leaflet area and its relation with closure area measured by 3-dimensional (3D) echocardio

Publikováno v: Acta radiologica (Stockholm, Sweden : 1987). 58(5)

Background Heavy coronary artery calcification (CAC) impairs diagnostic accuracy of coronary computed tomography angiography (cCTA) and is considered to be a major limitation. Purpose To investigate the effect of non-evaluable CAC seen on cCTA on cli
