Ventriculography (LV Gram) - The Merck Manuals
Ventriculography (LV Gram) A catheter (center) is inserted into the left ventricle (LV). Contrast is then injected into the LV under fluoroscopy and the ejection fraction is visually estimated.
Management of Patients at Risk for and With Left Ventricular …
2022年9月15日 · Pathophysiology. A commonly accepted paradigm (based on Virchow’s triad of thrombogenesis) posits the pathogenesis of LV thrombus as occurring as a result of the interplay of 3 factors: (1) stasis attributable to reduced ventricular function, (2) endocardial injury, and (3) inflammation/hypercoagulability (Figure 1).

Approaches to Echocardiographic Assessment of Left Ventricular …
2016年2月2日 · Left ventricular mass (LVM) is a well-established measure that can independently predict adverse cardiovascular events and premature death. 1-3 Population-based studies have revealed that increased LVM and left ventricular hypertrophy (LVH) as assessed by two-dimensional (2D) M-mode echocardiography measurements provide prognostic information be...
Assessing LV Systolic Function: From EF to Strain Analysis
2020年10月13日 · LV GLS is useful to detect future cardiotoxicity among patients receiving cardiotoxic chemotherapy, and to detect subclinical LV systolic dysfunction among family members of patients with heritable cardiomyopathies.
ARE ROUTINE LEFT VENTRICULOGRAMS NECESSARY DURING …
Left ventriculography (LVG) and echocardiography both provide similar information about left ventricular function and mitral regurgitation (MR). LVG carries the additional risk of contrast induced nephropathy. We assessed whether echocardiography might be an adequate substitute for LVG and obviate contrast risk. Methods.
NORMAL VALUES OF LEFT VENTRICULAR LONGITUDINAL AND …
Normal ranges of layer specific strain (longitudinal and circumferential) are provided in this meta-analysis according to 3 vendors: EchoPAC, Toshiba and VVI. Layer specific strain decrease from the endocardial to the epicardial layer in both longitudinal and circumferential strain.
Optimal use of left ventriculography at the time of cardiac ...
2014年11月4日 · Left ventriculography has gone from the status of prima ballerina to understudy in the ballet of left ventricular assessment. Critics argue that it adds to the cost and risk of cardiac catheterization and may be replaced by noninvasive imaging 1.
Left Ventricular Structure and Risk of Cardiovascular Events: A ...
2015年9月15日 · Greater left ventricular mass (LVM) and lower left ventricular (LV) systolic function, measured by echocardiography, are associated with excess adverse cardiovascular disease (CVD) events including coronary heart disease, 1 heart failure (HF), 2 – 4 stroke, 5 and both CVD and all-cause mortality. 6 – 10 Lower LV systolic function shown by ...
Assessment of Left Ventricular Function by Echocardiography:
The volume-based measurement of left ventricular ejection fraction (LVEF) is fundamentally different from direct measurement of myocardial motion by tissue Doppler imaging and myocardial deformation, and the reliability and precision of these measurements are also different.
