Percutaneous pulmonary valve implantation

Percutaneous pulmonary valve implantation Percutaneous pulmonary valve implantation has the elite distinction that it was first percutaneous intervention for a regurgitant lesion in humans [1]. Bonhoeffer P et al described the development of a system for percutaneous stent implantation combined with valve replacement for right ventricle to pulmonary artery prosthetic conduit with valve dysfunction [2]. They used it in a 12 year old boy with stenosis and regurgitation of a prosthetic conduit from right ventricle to pulmonary artery. Percutaneous implantation of bovine jugular valve in the conduit was achieved successfully in 2000. Echo, angio and hemodynamic assessment showed no residual regurgitation and partial relief of conduit stenosis. There were no complications and patient was in good physical condition at one month follow up. A report of 58 patients with a mean age of 16 years was published in 2005 [3]. Majority had variants of tetralogy of Fallot or transposition of great arteries with ventricular sepal defect and pulmonary stenosis. They had undergone right ventricular outflow tract reconstruction in infancy with valved conduit and presented in later life for reintervention for pulmonary regurgitation and stenosis. There was significant fall in right ventricular pressure, right ventricular outflow tract gradient and pulmonary regurgitation. There was no mortality in the series. Data on 155 patients was published in 2008 [4]. Follow up was up to 83.7 months. Freedom f...
