Why the study?

Does transthoracic three-dimensional echocardiography accurately assess right ventricular volume and mass compared to magnetic resonance imaging in patients with normal or enlarged right ventricles?

Population

16 patients

Comparison

Transthoracic three-dimensional echocardiography vs Magnetic resonance imaging

Design

Cross-sectional

Discussion

Implication

3D echocardiography may aid right ventricular end-diastolic volume assessment; leaves open reliability for systolic volumes and mass pending validation.

Key Points

This research aims to assess and compare right ventricular volume and mass using transthoracic echocardiography against magnetic resonance imaging.
Measurements of right ventricular volumes performed on datasets acquired by transthoracic echocardiography and compared to magnetic resonance imaging.
Volumes measured during end systole and end diastole; ejection fraction calculated.
Manual outlining of 2 mm thick slices of the ventricle, with volumes calculated by multiplying slice areas by thickness.
End diastolic volume correlation: r = 0.95 (limits of agreement -3.5 to 12.5 ml).
End systolic volume correlation: r = 0.87 (limits of agreement -4.0 to 16.4 ml).
End systolic right ventricular mass correlation: r = 0.81 (limits of agreement -7.0 to 20.6 g), indicating difficulties in mass measurement.

Structured PICO

Does transthoracic three-dimensional echocardiography accurately assess right ventricular volume and mass compared to magnetic resonance imaging in patients with normal or enlarged right ventricles?

Population

16 patients (3 with normal hearts, 3 after surgical repair of coarctation of the aorta, 9 following repair of tetralogy of Fallot, and 1 with Mustard atrial repair of complete transposition of the great arteries)

Intervention

Transthoracic three-dimensional echocardiography

Comparator

Magnetic resonance imaging (performed on the same day)

Outcome

Right ventricular volume (end systole and end diastole) and right ventricular mass (end systole)surrogate

Transthoracic 3D echocardiography is acceptably accurate for measuring end-diastolic right ventricular volumes compared to MRI, but less reliable for end-systolic volumes and mass.
