AbstractAims: This study sought to explore right (RV) and left ventricular (LV) mechanics and ventricular–ventricular interaction in adolescents and young adults late after percutaneous balloon pulmonary valvoplasty (PBPV) for valvar pulmonary stenosis (PS). Methods and results: Potential late effects of PS despite PBPV on cardiac mechanics have not been well defined. Thirty-one patients aged 20.2 ± 7.6 years were studied at 18 ± 6 years after PBPV. Ventricular myocardial deformation was determined using speckle tracking echocardiography, while RV and LV volumes and ejection fraction as well as LV systolic dyssynchrony index were assessed by three-dimensional echocardiography. The results were compared with those of 30 controls. Pulmonary regurgitation, mostly trivial to mild, was present in 90% (28/31) of patients. Compared with controls, patients had significantly greater RV end-diastolic (P < 0.001), RV end-systolic (P < 0.001), and LV end-systolic (P = 0.04) volumes as well as lower LV ejection fraction (P < 0.001). For deformation, patients had significantly reduced RV longitudinal systolic strain (P = 0.004), decreased LV circumferential systolic strain (P < 0.001), and strain rate (P = 0.001) as well as greater LV mechanical dyssynchrony (P < 0.001). In patients, RV end-diastolic and end-systolic volumes correlated with LV circumferential strain (r = −0.47, P = 0.008 and r = −0.36, P = 0.049, respectively) and dyssynchrony (r = 0.53, P = 0.002 and r = 0.49, P = 0.005, respectively). Patients who had PBPV at age ≤1 year had ventricular deformation indices similar to those who had interventions beyond 1 year. Conclusion: Impaired RV and LV mechanics and adverse ventricular–ventricular interaction occur in adolescents and young adults late after balloon valvoplasty for isolated valvar PS.
