Homograft valved right ventricle to pulmonary artery conduit as a modification of the Norwood procedure.
BACKGROUND The use of a right ventricle to pulmonary artery (RV-PA) conduit in the Norwood procedure has been proposed to increase postoperative hemodynamic stability. A valve within the conduit should further decrease RV volume load. We report our clinical experience with this modification. METHODS AND RESULTS From February 2002 through August 2005, we performed 88 consecutive Norwood proced...
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...
متن کاملSevere calcification of a Shelhigh stentless valved conduit.
A 74-year old patient developed severe aortic valve regurgitation 11 years following root replacement using a stentless Shelhigh tube-graft. Computed tomography scan showed a heavily calcified aortic conduit (Fig. 1), although the company claims that detoxification process eliminates residual glutaraldehyde and ensures less calcification in the long term. The patient underwent successful transa...
متن کاملUse of a Valved-Conduit for Exclusion of the Infected Portion in the Prosthetic Pulmonary Valve Endocarditis
A 51-year-old male was admitted to the hospital with complaints of fever and hemoptysis. After evaluation of the fever focus, he was diagnosed with pulmonary valve infective endocarditis. Thus pulmonary valve replacement and antibiotics therapy were performed and discharged. He was brought to the emergency unit presenting with a high fever (>39℃) and general weakness 6 months after the initial ...
متن کاملReconstruction of right ventricular outflow with a valved homograft conduit.
Wheadey, D. J., Prusty, S., and Ross, D. N. (1974). Thorax, 29, 617-623. Reconstruction of right ventricular outflow with a valved homograft conduit. Since 1966 a conduit of homograft ascending aorta with its valve has been used for reconstruction of the right ventricular outflow. This technique has been applied to 123 operations for pulmonary autograft replacement of the aortic valve, 48 opera...
