Abstract
Transcatheter
pulmonary-valve implantation has revolutionized therapy for right ventricular
outflow tract dysfunction. Bonhoffer et al were the first to describe implantation
of a stented bovine jugular venous valve in animals [1] and humans [2,3]. Since
then, the Melody valve has been implanted in thousands of patients with
pulmonary homograft dysfunction [4]. The Edwards-Sapien valve, originally
designed for aortic valve dysfunction, has also been utilized in patients with
pulmonary valve dysfunction, with or without a
homograft [5–7]. Until
recently, only 23 and 26 mm Sapien valves were available. Edwards Lifesciences (Irvine,
CA) recently received approval for the use of lower profile Sapien XT valves,
including a 29-mm valve. In this report, we describe implantation of a 29 mm
Sapien XT valve in the pulmonary position of a pediatric patient, using a new
low-profile sheath and delivery system.
