We report our experience of percutaneous valve insertion in pulmonary position in
Over the past 40 years, prosthetic conduits have been developed to surgically establish
continuity between the right ventricle and the pulmonary artery. However, stenosis
and insufficiency of the conduit due to valvular degeneration or panus ingrowth frequently
occur, limiting patients' lifespan. Percutaneous stenting of conduits has recently
emerged as a technique for delaying surgical replacement, but it creates a pulmonary
regurgitation when crossing the valve.
Seven children and one adult with stenosis and/or insufficiency of the pulmonary graft
underwent percutaneous implantation of a bovine jugular valve in pulmonary position.
Percutaneous pulmonary valve (PV) replacement was successful in all patients. No complications
occurred in early follow-up. Angiography, hemodynamic studies and echocardiography
after the procedure showed no significant regurgitation of the implanted valve. Implantation
was effective in relieving the obstruction in five patients. All patients showed improvement
in their clinical status at the latest follow-up (mean 10.1 months).
Non-surgical insertion of the PV is possible without any major complications. This
new technique may have an important role in the management of conduit obstructions
and pulmonary regurgitation.
