A limited experience with an initial series of nine patients operated upon for tricuspid atresia using a modified superior vena cava to right pulmonary artery anastomosis is presented. The modified technique is described and illustrated. It avoids permanent disruption of pulmonary artery continuity and the high incidence of superior vena cava syndrome. In short, the right pulmonary artery is not severed, the azygos vein is always ligated, the superior vena cava is not mass ligated and is subjected to delayed interruption.Analysis of the results shows an operative and overall mortality of 33 %. The advantages of this modified surgical approach are outlined.
The St Jude Hydrodymanic plus (Hp) and Sorin Bicarbon valves had similar performance and a better hemodynamic trend when compared to the Carbomedics-R valve in patients with large body surface areas. The Carbomedics-R valve shows a ineffective use of the total area of the prosthesis both at rest and after exercise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
