What is a Contegra conduit?
The Contegra® Conduit is an integrated valved conduit for reconstruction or replacement of the natural right ventricular outflow tract (RVOT) or replacement of a failed homograft or composite pulmonary conduit in patients.
What is a pulmonary valve conduit?
Children and adults with pulmonary valve disease may have narrowed pulmonary valves and may need surgery for placement of a right ventricular outflow tract (RVOT) pulmonary conduit or surgical valve. A pulmonary conduit is a tube that connects the heart to the lungs.
What is bovine jugular vein?
The bovine jugular vein: a totally integrated valved conduit to repair the right ventricular outflow. J Heart Valve Dis.
What is a contegra valve?
Contegra is a glutaraldehyde-crosslinked, heterologous bovine jugular vein with a competent tri-leaflet venous valve. The device is available in 6 sizes in even increments between 12 and 22 mm inside diameter, measured at the inflow end.
What is contegra graft?
Abstract. Introduction: The Contegra® bioprosthetic valved conduit, a glutaraldehyde-preserved valve-containing bovine jugular vein graft (Contegra, Medtronic Inc., Minneapolis MN, USA) introduced for clinical trials in 1998, is used for reconstruction of the right ventricular outflow tract (RVOT), mainly in children.
How long does a heart conduit last?
Many repair operations for congenital heart defects involve the replacement of valves and/or the insertion of conduits (basically tubes) to redirect blood flow. Most surgically implanted valves or conduits will last 10-20 years before they wear out, become obstructed, or lose efficiency.
Where is the jugular vein in cattle?
Position the needle over the jugular groove cranial to where your thumb is raising the vein. Hold the needle at an angle of about 45 degrees to the skin surface. Push the needle through the skin and into the jugular vein following the direction of jugular with the needle.
Where is jugular vein?
neck
jugular vein, any of several veins of the neck that drain blood from the brain, face, and neck, returning it to the heart via the superior vena cava.
What is a Melody valve?
The Melody Transcatheter Pulmonary Valve (also known as a “Melody valve”) is a replacement pulmonary heart valve. It’s used to replace a blocked or leaky valve that has been previously repaired to correct congenital heart defects present at birth.
What does Rvot mean?
Of the outflow tract tachycardias, the right ventricular outflow tract tachycardias (RVOT) are the most common. These tachycardias have a typical characteristic ECG appearance with a left bundle branch block appearance and are positive in the inferior leads of the ECG.
How long does a bovine pulmonary valve last?
Reports suggest that the average lifetime of a cow valve replacement is about 10 to 15 years.
Where does the contegra valved conduit come from?
Derived from a bovine jugular vein, the Contegra Conduit has no discontinuity between the lumen of the conduit and the trileaflet venous valve it incorporates. It is designed to allow the passage of blood across a continuous tissue interface and natural valve sinus.
How is the contegra conduit derived from a bovine vein?
Natural Derived from a bovine jugular vein, the Contegra Conduit has no discontinuity between the lumen of the conduit and the trileaflet venous valve it incorporates. It is designed to allow the passage of blood across a continuous tissue interface and natural valve sinus.
What is an integrated valved conduit for RVOT?
The Contegra® Conduit is an integrated valved conduit for reconstruction or replacement of the natural right ventricular outflow tract (RVOT) or replacement of a failed homograft or composite pulmonary conduit in patients.
How is a bovine valve similar to a heart valve?
bovine valve is similar to the human heart valve. The Contegra conduit is used to allow surgical correction or reconstruction of the natural rVoT and to provide and/or restore pulmonary valve function — enabling blood to flow
