ABSTRACT
PURPOSE:
This study was done to compare the parameters of left ventricular (LV) function obtained by multidetector computed tomography coronary angiography (MDCT-CA) using 64-slice equipment with those obtained using twodimensional echocardiography (2D-SE) considered as reference standard. MATERIALS ANDMETHODS:
Between April 2008 and September 2009, 116 consecutive patients were studied with both techniques. We analysed the parameters commonly sampled in echocardiography and related them with those retrieved with MDCT-CA septal thickness, posterior wall thickness, diameter of ascending aorta, diameter and volumes in end-systolic and end-diastolic phase, ejection fraction, stroke volume, cardiac output and heart mass.RESULTS:
Good correlation was found measuring septal thickness (r=0.470; p=0.001), and diameters of the ascending aorta. Correlation between systolic and diastolic diameters obtained with the two techniques was good. Poor correlation was attained measuring thickness of the posterior wall (r=0.243; p=0.104). MDCT-CA consistently overestimated the average volumes; diastolic and systolic volumes showed significant correlation (r=0.0456; p= 0.002; r=0.640; p<0.001). Ejection fraction agreement showed a significant correlation (r=0.626; p<0.001).CONCLUSIONS:
MDCT-CA provides parameters of cardiac function comparable to those found in echocardiography. MDCT-CA although used primarily for coronary noninvasive imaging can provide additional information on ventricular function useful to the diagnostic workup of cardiac patients.
