Why the study?

How does magnetic resonance velocity mapping compare to Doppler echocardiography for measuring mitral valve flow in patients with ischemic heart disease?

Population

19 patients with known coronary artery disease (mean age 62 years, 11 with previous myocardial infarction)

Comparison

Magnetic resonance velocity mapping of blood… vs Doppler echocardiography

Design

Cross-sectional

Discussion

Implication

MR velocity mapping should not replace echocardiography for atriosystolic assessment in ischemic disease; leaves open its utility for early diastolic filling.

Key Points

To compare mitral valve flow measurement using MR velocity mapping with Doppler echocardiography in patients with ischemic heart disease.
Nineteen patients with known coronary artery disease underwent cine MR velocity mapping and Doppler echocardiography.
Measurements included early filling velocity and early deceleration using both techniques.
The mean peak early filling velocity was 60.1 cm/sec with MR vs 59.4 cm/sec with echocardiography (P = .732).
Atrial filling velocity was significantly lower with MR (51 cm/sec) compared to echocardiography (62 cm/sec, P = .002).
MR velocity mapping accurately measures early diastolic filling but underestimates atrial systolic filling.

Structured PICO

How does magnetic resonance velocity mapping compare to Doppler echocardiography for measuring mitral valve flow in patients with ischemic heart disease?

Population

19 patients with known coronary artery disease (mean age 62 years, 11 with previous myocardial infarction)

Intervention

Magnetic resonance (MR) velocity mapping of blood flow across the mitral valve

Comparator

Doppler echocardiography

Outcome

Peak early filling velocity, early deceleration, and peak atriosystolic velocitysurrogate

MR velocity mapping provides accurate measurements of early diastolic filling but underestimates atriosystolic filling velocity compared to Doppler echocardiography.
