Echocardiographic versus angiographic measurement of the aortic valve annulus in children undergoing balloon aortic valvuloplasty: method affects outcomes.

Objective: Operators are mindful of the balloon-to-aortic annulus ratio when performing balloon aortic valvuloplasty. The method of measurement of the aortic valve annulus has not been standardised.

Methods And Results: Patients who underwent aortic valvuloplasty at two paediatric centres between 2007 and 2014 were included.

Premounted stents for branch pulmonary artery stenosis in children: A short term solution.

Objective: Define outcomes of premounted stent implantation (PMS) for branch pulmonary artery stenosis (BPAS).

Background: PMS for BPAS in children raises concern of long term viability, with limited maximal expansion.

Methods: We reviewed our cardiac database over an 11-year period ending in 2013.

Relation of Aortic Valve Morphologic Characteristics to Aortic Valve Insufficiency and Residual Stenosis in Children With Congenital Aortic Stenosis Undergoing Balloon Valvuloplasty.

Aortic valve morphology has been invoked as intrinsic to outcomes of balloon aortic valvuloplasty (BAV) for congenital aortic valve stenosis. We sought to use aortic valve morphologic features to discriminate between valves that respond favorably or unfavorably to BAV, using aortic insufficiency (AI) as the primary outcome. All patients who underwent BAV at 2 large-volume pediatric centers from 2007 to 2014 were reviewed.
