Left ventricular inflow propagation velocity for diastolic function testing: head-to-head comparison between velocity-encoded MRI and color M-mode Doppler echocardiography
Background The inflow propagation velocity (Vprop) of the early filling wave has been proposed as an accurate marker of left ventricular (LV) diastolic function [1]. Traditionally, Color M-mode echo Doppler is used for Vprop-assessment. However, this method has not been validated against an alternative modality such as velocity-encoded (VE) MRI for assessing Vprop. The purpose of this study was...
متن کاملHigh-temporal velocity-encoded MRI for the assessment of left ventricular inflow propagation velocity: head-to-head comparison with Color M-mode echocardiography
Methods 43 patients with ischemic heart failure (61±11years) and 22 healthy volunteers (29±13years) were included. Vp by Color M-mode echocardiography (Vp-echo), was measured according to current recommendations (Figure 1). VE-MRI was performed on a 1.5 or 3.0 Tesla MRI system during free breathing, with single-direction in-plane velocity-encoding in phase-encoding direction, angulated parallel...
متن کاملWhat parameters affect left ventricular diastolic flow propagation velocity? in vitro studies using color m-mode doppler echocardiography
BACKGROUND Insufficient data describe the relationship of hemodynamic parameters to left ventricular (LV) diastolic flow propagation velocity (Vp) measured using color M-mode Doppler echocardiography. METHODS An in vitro LV model used to simulate LV diastolic inflow with Vp measured under conditions of varying: 1) Stroke volume, 2) heart rate (HR), 3) LV volume, 4) LV compliance, and 5) trans...
متن کاملRatio of left ventricular peak E-wave velocity to flow propagation velocity assessed by color M-mode Doppler echocardiography in first myocardial infarction: prognostic and clinical implications.
OBJECTIVES To determine the ability of the ratio of peak E-wave velocity to flow propagation velocity (E/Vp) measured with color M-mode Doppler echocardiography to predict in-hospital heart failure and cardiac mortality in an unselected consecutive population with first myocardial infarction (MI). BACKGROUND Several experimental studies indicate color M-mode echocardiography to be a valuable ...
متن کاملComparison between M-Mode and Doppler echocardiography in diagnosis
Introduction: Patent ductus arteriosus (PDA) is the persistence of a normal fetal structure between left pulmonary artery and descending aorta. Persistence of this fetal structure beyond 10 days of life is considered abnormal. In this study we compared M-Mode and Doppler echocardiography in diagnosis of PDA in children at Aliasghar Hospital in Zahedan and Children hospital in Bandar Abbas for...
