Comparative StudyQuantitative assessment of pulmonary insufficiency by Doppler echocardiography in patients with adult congenital heart disease.
We determined the utility of continuous wave (CW) Doppler for quantification of pulmonary insufficiency (PI) confirmed by pulmonary angiography in patients with postoperative adult congenital heart disease. A total of 41 patients with PI were divided into two groups on the basis of PI severity by pulmonary angiography: group A (n = 27) with severe PI and group B (n = 14) with mild or moderate PI. Nine patients in group A had pulmonic valve replacement and reverted to mild PI after surgery. ⋯ By binary logistic regression, NFT and PHT were the best predictors for severe PI. An NFT of 80 ms had 84% sensitivity and 93% specificity, and a PHT of 100 ms had 93% sensitivity and 93% specificity for identifying angiographically severe PI. CW Doppler accurately distinguishes severe from lesser degrees of PI in patients with postoperative adult congenital heart disease.

Comparative StudyAssessment of diastolic function during exercise echocardiography: annulus mitral velocity or transmitral flow pattern?
We hypothesize that the change in the left ventricular (LV) diastolic pattern (DP) may be measured with high reproducibility and correlates with exercise echocardiography (EE) better than the ratio of early LV inflow velocity to early diastolic annulus velocity (E/e' index). ⋯ E/e' does not allow further stratification in patients with exercise RP. We propose both measurement of E/e' and determination of the LV-DP (a quickly assessable variable) for the assessment of diastolic function during EE. However, when an RP persists or develops with exercise, further assessment may not be more informative.

Randomized Controlled TrialEffect of shunt type on echocardiographic indices after initial palliations for hypoplastic left heart syndrome: Blalock-Taussig shunt versus right ventricle-pulmonary artery conduit.
The study objective was to compare echocardiographic indices in infants with hypoplastic left heart syndrome (HLHS) randomized to different surgical pathways. ⋯ Right ventricle size and function do not appear significantly affected by surgical type of initial palliation for HLHS, and this correlates with early outcome. Echocardiographic Doppler findings correlate well with the expected physiologies of the different shunts as these infants progress through initial palliative strategies.
