Comparison of strain doppler echocardiography and radiologic left ventriculography for quantitative assessment of regional myocardial function.
OBJECTIVE
We aimed to study the comparison of strain and strain rate parameters with conventional left ventriculography derived regional function.


METHODS
Forty patients were included in the study. The study group was selected from patients who had undergone left ventriculography and coronary angiography for clinical indications. Regional myocardial function was assessed using the centerline method via ACOM PC Quantcor LVA measurement system. Patients were also evaluated with echocardiography. Strain and strain rate Doppler echocardiographic measurements were compared with conventional left ventriculography at anterobasal, anterolateral, inferior and posterobasal segments.


RESULTS
Radiological left ventricular radial shortening was found to correlate with longitudinal strain shortening in all ventriculographic segments examined (anterobasal, r = 0.771, P < 0.0001; anterolateral, r = 0.790, P < 0.0001; posterobasal, r = 0.861, P < 0.0001; inferior, r = 0.815, P < 0.0001). Correlation was persistent both in patients with or without coronary artery disease. The sensitivity of a peak systolic longitudinal strain >12.5% for prediction of patients with radial shortening >or=20% was 75%, with a specificity of 100%. However, no relationship could be demonstrated between radiological left ventricular radial shortening and strain rate measurements.


CONCLUSIONS
In our study it was shown that regional wall motion can be measured quantitatively via strain Doppler echocardiography with the left ventriculography as reference.
