Abstract:
Objective To discuss the factors that maybe related to the analysis of results of percutaneous balloon pulmonary valvuloplasty (PBPV) and the changes of cardiac morphology after PBPV. Methods Multiple linear regression was used to study peak gradient, balloon-anulus ratio (BAR), pulmonary orifice area and time of inflation before and after PBPV. One hundred and thirty-eight patients (age between 6 months and 28 years old, mean 8.34?0.81). T test was used to study the diameter and thickness of the right ventricle (RV), and Rv 1 of ECG before and during the follow-up. F test was used to determine peak gradient before and after PBPV and during the follow-up. Results There was a notable reduction in the peak to peak gradient from 13.55?0.69 kPa to 4.51?0.41 kPa (P
