Ross operation and right ventricular outflow tract reconstruction with stentless xenografts.
نویسندگان
چکیده
Traditionally a homograft valve is used as a pulmonary replacement device for the Ross operation. Right ventricular outflow tract reconstruction during aortic valve replacement with an autograft was performed with stentless xenograft valves in nine patients. Hemodynamic performance is satisfying, but, long term evaluation is needed.

Magnetic resonance imaging of stentless xenografts for reconstruction of right ventricular outflow tract.
The objective was to overcome allograft shortage during the Ross operation; stentless xenografts were carefully evaluated for hemodynamic behavior and valve deterioration during medium term follow-up. Between January 10, 1994 and January 4, 1996 nine adult patients (age 31-51 years) underwent aortic valve replacement with an autologous pulmonary valve and right ventricular outflow tract reconst...
متن کاملAlternative to pulmonary allograft for reconstruction of right ventricular outflow tract in small patients undergoing the Ross procedure.
OBJECTIVES Small pulmonary allografts are difficult to obtain, thus we now use a tailor-made right ventricle to pulmonary artery (RV-PA) conduit for the Ross procedure, consisting of a fresh non-treated autologous pericardial (AP) patch for the posterior wall and expanded polytetrafluoroethylene (ePTFE) monocusp patch for the anterior wall. Long-term durability and RV function were assessed. ...
متن کاملThe role of transesophageal echocardiography during the Ross procedure.
Pulmonary autograft replacement of the aortic valve, the “Ross procedure,” involves transplantation of the native pulmonary valve into the aortic position and reconstruction of the right ventricular outflow tract with a cryopreserved pulmonary or aortic homograft. In any surgeon’s hands this operation is technically challenging and successful performance of the Ross procedure requires strategie...
متن کاملInfectious false aneurysm of the right ventricular outflow tract after repair of congenital heart defect treated with Freestyle aortic bioprosthesis.
OBJECTIVES False aneurysm of the right ventricular outflow tract (RVOT) is one of complications after surgery of congenital heart disease. It is controversial about materials for reconstruction of RVOT in this setting, when associated with pulmonary hypertension or bacterial infection. Pulmonary homograft seems to be the first choice, but its availability is extremely limited in Japan. METHOD...
متن کاملModified Ross procedure using a conduit with a synthetic valve.
OBJECTIVE In the Ross procedure, a homograft conduit is commonly used in place of an autotransplanted pulmonary valve. Homograft availability may be a problem and has resulted in a search for alternatives. We performed a modified Ross procedure for right ventricular outflow tract reconstruction with a synthetic valved conduit as an alternative to homograft. Our early results of valvular and rig...
