A valve within the conduit should further decrease RV volume load. We report our clinical experience with this modification.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Methods and Results\u2014<\/jats:italic>\n            <\/jats:bold>\n            From February 2002 through August 2005, we performed 88 consecutive Norwood procedures using RV-PA conduits. We used composite valved conduits made from cryopreserved homograft and polytetrafluoroethylene (PTFE) in 66 cases (54 pulmonary, 12 aortic homografts), other valved conduits in 14, and unvalved PTFE in 8 cases. Hospital survival was 88.6% overall and increased to 93.1% after the initial year. Early interventions were required in 18 patients (16 for cyanosis). Prestage II cardiac catheterization was performed at a mean age of 126 days. Mean Qp\/Qs was 1, with mean aortic saturation 71%, mean O\n            <jats:sub>2<\/jats:sub>\n            extraction 24%, and mean right ventricular end-diastolic pressure 9 mm Hg. Patient weight, use of an aortic homograft valve in the conduit, stage I palliation within the first year of our experience, and low O\n            <jats:sub>2<\/jats:sub>\n            extraction and high transpulmonary gradient prestage II were risk factors for overall death. Early interventions were more frequent in aortic valve conduits compared with all other conduits.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Conclusions\u2014<\/jats:italic>\n            <\/jats:bold>\n            The valved RV-PA conduit was associated with low early mortality after the Norwood procedure. The majority of these patients had normal cardiac output and well-maintained RV function. There may be a higher risk for early conduit interventions and death when aortic valve homografts are used in the RV-PA conduit.\n          <\/jats:p>","DOI":"10.1161\/circulationaha.105.001438","type":"journal-article","created":{"date-parts":[[2006,7,7]],"date-time":"2006-07-07T01:56:58Z","timestamp":1152237418000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":18,"title":["Homograft Valved Right Ventricle to Pulmonary Artery Conduit as a Modification of the Norwood Procedure"],"prefix":"10.1161","volume":"114","author":[{"given":"Olaf","family":"Reinhartz","sequence":"first","affiliation":[{"name":"From the Divisions of Pediatric Cardiothoracic Surgery and Pediatric Cardiology, Stanford University School of Medicine, Stanford, Calif."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V.
