Advances in risk factors for restenosis after percutaneous balloon pulmonary valvuloplasty for congenital pulmonary valve stenosis
Congenital pulmonary valve stenosis(PS)is a common congenital heart disease.Simple PS makes up approximately 8％～10％of congenital heart disease,and 20％of complex congenital heart disease complicated with PS.Percutaneous balloon pulmonary valvuloplasty(PBPV),which has undergone nearly 40 years of continuous improvement,has emerged as the preferred treatment for PS due to its superior safety and less trauma.However,residual stenosis was found in some patients during long-term follow-up,and repeat PBPV or even surgical repair was required.Identifying the risk factors for postoperative restenosis will further improve postoperative outcomes and reduce the probability of reintervention in the future.This article reviews the risk factors for restenosis of PS after PBPV including age,severity,morphologic characteristics of the valve leaflets and the choice of the balloon.
