Rv Pa Conduit Change

At our institution transcatheter conduit dilation and or stenting is often performed in an effort to relieve rv pa conduit obstruction and to minimize rv work before referral for conduit reoperation.

Rv pa conduit change.

In conclusion multiple rv pa conduit revisions were required in patients who survived to adulthood with many replacements taking place during adolescence. 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 rv pa was constructed with a 5 mm conduit. Freedom from conduit reoperation after conduit 2 called conduit 3 was 80 at 5 years and 39 at 10 years.

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. A valve within the conduit should further decrease rv volume load. Methods and results from february 2002 through august 2005 we performed 88 consecutive norwood. Rv pa conduits are also part of a many complex surgeries for congen ital heart disease including the ross procedure.

Patients in the bts group received a 4 mm shunt. The cove point foundation congenital heart resource center is the world s largest resource for information on pediatric and adult congenital heart disease. 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. 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.

They can be placed for a variety of heart defects including tetralogy of fallot pulmonary atre sia or pulmonary stenosis. 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. The question of the ideal rv pa conduit has been extensively investigated and needless to say a perfect rv pa conduit does not exist. 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.
