Key result
Doppler echocardiography combined with NTproBNP/BNP accurately identified pulmonary artery hypertension in patients with congenital heart disease (AUC 0.857; 95% CI 0.676-1; P<0.001).
Why the study?
Pulmonary artery hypertension is a common complication of congenital heart disease linked to worse outcomes, prompting evaluation of Doppler echocardiography combined with NTproBNP/BNP as a screening strategy.
Does Doppler echocardiography combined with NTproBNP/BNP improve the diagnosis of pulmonary artery hypertension in patients with congenital heart disease?

Background. Pulmonary artery hypertension (PAH) is a common complication of congenital heart disease (CHD) and is associated with worse outcomes and increased mortality. The Doppler echocardiography (DE) is a commonly used imaging tool for both diagnosis and follow‐up examination of PAH. Here is to evaluate the diagnostic performance of DE combined with NTproBNP/BNP as screening strategy in PAH patients with CHD. Methods. A retrospective study in 64 patients with CHD has been carried out to compare estimate pulmonary artery systolic pressure (PASP) measured with DE to that measured with right heart catheterization (RHC). The Pearson correlation analyses were used to calculate the correlation coefficients between RHC and DE. The Bland‐Altman analyses were carried out to assess the agreement between the two methods. ROC analyses were used to evaluate the diagnostic performance of DE, NTproBNP/BNP, and DE combined with NTproBNP/BNP. Results. Our data have demonstrated that a mild correlation (r = 0.4401, P < 0.01) was observed between PASP (78.1 ± 29.0 mmHg) measured during RHC and PASP (74.9 ± 19.7 mmHg) as estimated using DE. The Bland‐Altman analysis demonstrated that the bias for DE PASP estimates was 3.2 mmHg with 95% limits of agreement ranging from ‐49.53 to 55.90 mmHg. The results of DE showed an AUC of 0.848 (95% CI = 0.666‐1; P < 0.001), the sensitivity of which was 98.3% and the specificity was 77.8%. The AUC of NTproBNP/BNP for the identification of PAH was 0.804 (95% CI = 0.651‐0.956; P < 0.001), the sensitivity of which was 81.4% and the specificity was 87.5%. The AUC of DE combined with NTproBNP/BNP was 0.857 (95% CI = 0.676‐1; P < 0.001), of which sensitivity was 100% and specificity was 77.8%. The positive predictive value (PPV) and negative predictive value (NPV) were 96.6% and 100%, respectively. Conclusions. Our study shows that the Doppler echocardiography combined with NTproBNP/BNP has better diagnostic performance in pulmonary artery hypertension associated with congenital heart disease, especially when DE negative screening in PAH patients.
