We developed an expanded polytetrafluoroethylene (ePTFE) valved conduit for use in right ventricular outflow tract reconstruction, a procedure used in various congenital heart diseases with decreased pulmonary blood flow, particularly Tetralogy of Fallot.
Until more information is available regarding long-term performance of the pulmonary root when implanted as a neoaortic root, as well as improved results for reconstruction of the right ventricular outflow tract, the Ross procedure should be used rarely.
Reconstruction of the right ventricular outflow tract (RVOT) is a key procedure in repair of Tetralogy of Fallot (TOF).
Crucial for the outcome of this kind of last-resort procedure is establishing good outflow for the recanalized vessels.
Trabeculectomy has been proposed as a valuable procedure, to facilitate the outflow of aqueous humor, but is not very effective in congenital glaucoma.
This group of procedures focuses on the sinus outflow tract, and is designed to improve sinus function by restoring sinonasal physiology.
Surgical treatment can be separated into procedures that improve aqueous outflow through the drainage channels (goniosurgery such as goniotomy and trabeculotomy), treatments that by destroying the ciliary body reduce aqueous humor production (cyclodestruction), or surgical procedures that drain aqueous through an alternative way (trabeculectomy, glaucoma drainage devices) [ 131].
Pulmonary regurgitation (PR) that develops after right ventricular (RV) outflow reconstruction including the Rastelli and Norwood procedure may often result in serious cardiac events early after surgery.
A randomized prospective study was designed to compare the response of liver cells to ischemic-reperfusion injury during the application of two different ischemic procedures: inflow versus inflow plus outflow vascular occlusion of the liver.
In 127 patients (55.7%), an associated vascular procedure was performed to improve the outflow.
