Rv Pa Conduit Change

In total correction the vsd is closed and rv pa conduit is interposed between the rv and the distal pulmonary artery which was excised from the truncal artery b in ross procedure 2 aortic valve replacement is performed with a pulmonary autograft and a valved conduit is used as a substitute for it fig.

Rv pa conduit change.

Rv pa conduits are also part of a many complex surgeries for congen ital heart disease including the ross 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. In conclusion multiple rv pa conduit revisions were required in patients who survived to adulthood with many replacements taking place during adolescence. Comparisons between rv pa and bts groups showed no difference for weight gestational age prenatal diagnosis hlhs variant associated diagnoses ascending aortic size ventricular function av valve function and pulmonary venous obstruction.

Methods and results from february 2002 through august 2005 we performed 88 consecutive norwood. Freedom from conduit reoperation after conduit 2 called conduit 3 was 80 at 5 years and 39 at 10 years. Cove point contains comprehensive information on all congenital heart defects including atrial septal defect asd ventricular septal defect vsd hypoplastic left heart syndrome hlhs and tetralogy of fallot tof. We report our clinical experience with this modification.

The rv pa was constructed with a 5 mm conduit. They can be placed for a variety of heart defects including tetralogy of fallot pulmonary atre sia or pulmonary stenosis. A valve within the conduit should further decrease rv volume load. A right ventricle to pulmonary artery rv pa conduit is a means to supply blood flow to the lungs.

Most conduits in this adult cohort met size criteria for ppvi thereby offering these patients a potential alternative to surgical intervention for conduit failure. The cove point foundation congenital heart resource center is the world s largest resource for information on pediatric and adult congenital heart disease. The journey started in 1964 when rastelli and coworkers inserted a non valved pericardial tube as the first right ventricle to pulmonary artery rv pa conduit in a child with pulmonary atresia valved conduits were first used by ross and soon after by rastelli and since then have remained the mainstay of the treatment of rv pa discontinuity. Patients in the bts group received a 4 mm shunt.
