“…Moreover, echocardiographic assessment of PAAT values can assist in the evaluation of PH patients in routine followup and may reduce costs by decreasing the number of more advanced investigations such as cardiac magnetic resonance imaging. 34 A limitation of PAAT determination in CHD is the impaired reliability in patients with left-to-right shunts. 25 Therefore, patients with shunts and persistent ductus arteriosus were excluded from our study.…”

Background-Pulsed-wave Doppler determination of the pulmonary artery acceleration time (PAAT) as a surrogate for pulmonary artery pressure was found to be of clinical value for assessment of pulmonary hypertension (PH) with studies to date exclusively performed in adults. This study aims to provide representative, normal reference values for PAAT in children of all ages. Moreover, we validated abnormal PAAT values in 54 children with PH. Methods and Results-We conducted a prospective echocardiographic study in 756 healthy children (aged 1 day to 18 years) and in 54 children with PH. Possible associations of age, body length, body weight, body surface area, and heart rate on PAAT were investigated. The PAAT correlated positively with age (r=0.848), body length (r=0.871), body surface area (r=0.856), and body weight (r=0.825) and negatively with heart rate (r=−0.906). PAAT increased with age (neonates: median: 81 ms, range: 53-104; 18th year of life: median: 151 ms, range: 107-187). Receiver operating characteristic analysis for detecting PH patients using age-specific z scores showed an excellent performance of PAAT (P<0.001; area under the curve, 0.98; 95% confidence interval, 0.97-0.99) with a best cutoff score according to Youden index of -1.565 (sensitivity: 92%, specificity: 96%). PAAT values of PH patients negatively correlated (ρ=−0.497) with pulmonary vascular resistance. Conclusions-The PAAT normal reference values and z scores we provide here will be useful to identify children with a shortened PAAT. Abnormal PAAT values with scores <−2 were predictive of PH.

“…115 The RV area has been shown to correlate with the cardiac magnetic resonance-derived RV volume and can serve as a semiquantitative surrogate for the identification of RV dilatation. 116,117 The 3D echocardiographically derived RV volume is the most accurate echocardiographic method to estimate the RV volume compared with cardiac magnetic resonance. Compared with 2D techniques, 3D echocardiography results in better reproducibility and less underestimation of the RV volume.…”

“…Some have explored correlation between Doppler indicators of PR severity and regurgitant fraction calculated by MRI . Others have evaluated echocardiographic parameters of the right ventricle and their agreement with volumes and function estimated by MRI . There is an increasing interest in functional assessment including strain imaging that may add complimentary information and reveal subclinical disease.…”

Echocardiographic assessment of pediatric semilunar valve disease

et al. 2017

We reviewed echocardiography literature for the assessment and management of semilunar valve disease in children. A search was performed within the National Library of Medicine using the keywords aortic stenosis (AS), aortic regurgitation, pulmonary stenosis (PS), and pulmonary regurgitation in children. The search was further refined adding the keywords-pediatric, neonates, echocardiographic definition, classification, evaluation. Thirty-eight studies were included. For stenotic lesions, there were sufficient consistencies between Doppler and invasive gradients (especially for PS), while other quantitative parameters used in adults showed significant limitations when applied to children. Heterogeneities remain in the range of Doppler measurements utilized to define mild vs moderate vs severe AS/PS, and to guide management. There is sufficient consensus regarding indications for interventions. In regurgitant lesions, there is weak evidence supporting the use of quantitative or semiquantitative parameters after correction for body surface area; clear indications for intervention are lacking. Because adult echocardiographic recommendations cannot be simply translated to the pediatric age, more specific pediatric guidelines and standards for the assessment of semilunar valve disease are needed.
