first reported PBPV as a new method for treating PVS in 1982.
The main findings of this study indicate that PBPV is effective in the short- and medium-term follow-up with regard to safety and feasibility, as demonstrated by the immediate success rate of 92% and occurrence of restenosis in only 6.
PBPV can achieve satisfactory outcomes by relieving obstruction.
Similar to the results of our study, previous studies have reported the immediate effectiveness and safety of PBPV for different age groups.
carried out PBPV in 12 infants with critical PVS or pulmonary atresia with intact ventricular septum and reported two cases of guidewire perforation of the RVOT.
For those with isolated dome-shaped PVS, PBPV is recommended, as it is safe and minimally invasive.
To ensure the success of PBPV, it is crucial to select appropriate balloons.
29] Reoperation will encounter more problems including tissue adhesion, while PBPV can be repeated several times in the same patient.
