Abstract
Thirteen neonates with critical pulmonary valve stenosis/atresia underwent successful transcatheter balloon valvuloplasty using an umbilical artery "snare assisted" approach. This technique simplifies the procedure and avoids femoral artery injury by using the umbilical artery, reduces fluoroscopy exposure, and eliminates the need for a gradational approach which reduces costs.
