“…Right ventricular-pulmonary artery coupling (RV-PA coupling) refers to the relationship between RV contractility and RV afterload. The ratio between TAPSE and pulmonary artery systolic pressure (PASP) measured on echocardiography can serve as a non-invasive surrogate for invasively estimated RV-PA coupling (the ratio between RV end-systolic elastance and pulmonary arterial elastance, Ees/Ea), based on the assumption that TAPSE provides an estimate of RV contractility and PASP an estimate of RV afterload [10][11][12][13][14][15][16]. Normal RV-PA coupling means an appropriately matched RV function and pulmonary vascular resistance.…”

Background The recognition ability of right ventricular-pulmonary artery (RV-PA) coupling for coronary artery lesions (CAL) in children with Kawasaki disease (KD) has not been well characterized. This study aimed to determine whether RV-PA coupling is an independent the risk factors for CAL in children with KD. Methods Between October 2021 and August 2023, RV-PA coupling was assessed in 59 KD children using the ratio between echocardiographic tricuspid annular plane systolic excursion and pulmonary artery systolic pressure (PASP). Multivariable logistic regression analysis was used to identify the independent risk factors for CAL among the demographic, clinical, laboratory and echocardiographic data. Results Twenty-nine of 59 KD children had CAL according to the diagnostic criteria of echocardiography. There were significantly different white blood cell count, C-reactive protein, erythrocyte sedimentation rate, left ventricular ejection fraction, PASP and RV-PA coupling at admission, and significantly different acute/subacute phase ratio of RV-PA coupling between KD children with and without CAL (P < 0.05). Multivariate logistic regression analysis identified that acute/subacute phase ratio of RV-PA coupling (OR = 26.800; 95% CI, 1.276–562.668; P = 0.034) was an independent risk factor for CAL in children with KD. The area under receiver operating characteristic curve for the acute/subacute phase ratio of RV-PA coupling was 0.715 (95%CI: 0.624 - 0.825) to predict CAL in KD children (P < 0.05), with a sensitivity of 81.25% and a specificity of 62.57% at the optimal cutoff value of 0.839. Conclusion The acute/subacute phase ratio of RV-PA coupling was an independent risk factor for CAL in KD children.

“…Normal RV-PA coupling means an appropriately matched RV function and pulmonary vascular resistance. Decrease or increase in either RV contractility or RV afterload will result in change in RV-PA coupling, and RV-PA uncoupling portends a poor prognosis [10][11][12][13][14][15][16][17][18][19].…”
