Long-term results of surgical valvuloplasty for congenital valvar aortic stenosis in children

Long-term outcome of congenital aortic valve stenosis: predictors of reintervention

“…The observation that the degree of aortic regurgitation increases over time is universal, and is common to all case series, whether related to catheter or surgical intervention. 14,[20][21][22][23]33,[39][40][41] In the literature, we observed a 7-19% increase in the degree of aortic regurgitation directly after intervention, 16,20,31,38 and a 10-45% incidence of significant aortic regurgitation at late follow-up. 8,14,[23][24][25]31,34,38,39 Although risk factors for increasing aortic regurgitation have not been fully defined, it has been speculated that this is an inevitable occurrence because of the intrinsically abnormal morphology of the aortic valve, reflecting the modified natural history of this disorder.…”

“…Congenital aortic valve stenosis is a progressive lesion and risk of reintervention after initial procedure on aortic valve stenosis is high. 20,21,23,33,36,41 Most series identify the higher residual gradients or a progressive and recurrent systolic pressure gradient after the first procedure as predictors for reintervention. 7,26,31,34,38,40,45 In our study, the outcome of the first intervention on aortic valve stenosis in terms of immediate gradient reduction is comparable to that reported by others.…”

Management of severe aortic valve stenosis in the neonate

“…(23,24) The pros and cons of each intervention have been the subject of many publications. (25,26,27,28,29,30) Many studies have been published comparing the results of SV vs.…”

“…(25,26) However, if some of these variables are correctable and biventricular repair is still feasible, the Ross/Ross-Konno operation is an option when the child is older. (25,28) …”

Valvar Aortic Stenosis

“…If neonates are excluded, early mortality ranges up to 12%. In many reports mortality was zero when infants were excluded [17,25,69,[186][187][188][189][190].…”
