Our aim was to compare speckle\u2010derived measures of cardiac function to measurements routinely obtained by cardiac catheterization in children.<\/jats:p><\/jats:sec>Methods<\/jats:title>Echocardiograms were performed on the day of cardiac catheterization. Using Tomtec 2D Cardiac Performance Analysis, longitudinal strain (LS<\/jats:styled-content>), longitudinal strain rate (LSR<\/jats:styled-content>), early diastolic LSR<\/jats:styled-content>, and ejection fraction (EF<\/jats:styled-content>) for the right and left ventricle (RV<\/jats:styled-content> and LV<\/jats:styled-content>) were calculated via speckle tracking. Global LS<\/jats:styled-content> and LSR<\/jats:styled-content> were calculated for the LV<\/jats:styled-content>. These results were compared to cardiac index, maximum ventricular dp\/dt (max dp\/dt), ventricular end\u2010diastolic pressure (EDP<\/jats:styled-content>), and pulmonary capillary wedge pressure (PCWP<\/jats:styled-content>) obtained by fluid\u2010filled catheters. A blinded observer performed all echo measurements.<\/jats:p><\/jats:sec>Results<\/jats:title>Fifty studies were performed on 28 patients ages 4\u00a0months to 20\u00a0years old. Their diagnoses included cardiac transplant (48 studies), repaired AV<\/jats:styled-content> septal defect (1), and dilated cardiomyopathy (1). RVEDP<\/jats:styled-content> ranged from 2 to 22\u00a0mm Hg (median=6) and PCWP<\/jats:styled-content> ranged from 6 to 32\u00a0mmHg (median 10). LV<\/jats:styled-content> global LS<\/jats:styled-content> and LV<\/jats:styled-content> 2\u2010chamber LSR<\/jats:styled-content> by speckle\u2010tracking negatively correlated with LV<\/jats:styled-content> max dp\/dt (LV<\/jats:styled-content> global LS <\/jats:styled-content>R<\/jats:italic>=\u2212.83, P<\/jats:italic>=.001; LV<\/jats:styled-content> 2\u2010chamber LSR <\/jats:styled-content>R<\/jats:italic>=\u2212.69, P<\/jats:italic>=.009). RV LS<\/jats:styled-content> weakly correlated with max dp\/dt (R<\/jats:italic>=.363, P<\/jats:italic>=.002). Early diastolic strain rate did not correlate with EDP<\/jats:styled-content> in either ventricle.<\/jats:p><\/jats:sec>Conclusion<\/jats:title>Speckle\u2010derived measurements of function in the LV<\/jats:styled-content> have stronger correlation than the RV<\/jats:styled-content> to catheter\u2010derived measures.
