Right ventricular outflow tract reconstruction with bicuspid valved polytetrafluoroethylene conduit.
BACKGROUND In general, all conduits available for right ventricular outflow tract (RVOT) reconstruction eventually become stenotic or insufficient. Owing to the lack of an ideal conduit and with the hope of reducing the incidence of reoperations, we have developed and utilized a bicuspid valved polytetrafluoroethylene (PTFE) conduit for the reconstruction of the RVOT. The purpose of this study ...
متن کاملIn vitro evaluation of right ventricular outflow tract reconstruction with bicuspid valved polytetrafluoroethylene conduit.
Conduits available for right ventricular outflow tract (RVOT) reconstruction eventually become stenotic and/or insufficient due to calcification. In order to reduce the incidence of reoperations we have developed and used a bicuspid valved polytetrafluoroethylene (PTFE) conduit for the RVOT reconstruction. The purpose of this study is to investigate the hemodynamic performance of the new design...
متن کاملThermal treatment of expanded polytetraflu-oroethylene (ePTFE) membranes for reconstruction of a valved conduit.
The unique micro porous structure of expanded polytetrafluoroethylene (ePTFE) that allows bio-integration for fixation, as well as overall mechanical integrity make it used successfully in a number of biomedical and clinical applications, which include the reconstruction of the pulmonary valve in in right ventricular outflow tract reconstruction (RVOT) operations. The objective of this study wa...
متن کاملSurgical outcomes after superior vena cava reconstruction with expanded polytetrafluoroethylene grafts.
OBJECTIVES Graft occlusion is a problem after superior vena cava (SVC) reconstruction for thoracic malignancy. Expanded polytetrafluoroethylene (ePTFE) is considered to be an optimal material for venous reconstruction. METHODS We reviewed the hospital records of 13 patients who underwent complete resection of thoracic malignancy invading the SVC, including SVC reconstruction with ePTFE grafts...
متن کاملCardiovascular effects of right ventricle-pulmonary artery valved conduit implantation in experimental pulmonic stenosis.
Right ventricle (RV)-pulmonary artery (PA) valved conduit (RPVC) implantation decreases RV systolic pressure in pulmonic stenosis (PS) by forming a bypass route between the RV and the PA. The present study evaluates valved conduits derived from canine aortae in a canine model of PS produced by pulmonary artery banding (PAB). Pulmonary stenosis was elicited using PAB in 10 conditioned beagles ag...
