Comparison of Bovine jugularvein conduit and homograft in right ventricular outflow tract reconstruction / 中华胸心血管外科杂志

ABSTRACT

Objective To compare the clinical efficacy of BalMedic bovine jugular vein conduit (BalMedic) with homograft in right ventricular outflow tract reconstruction.Methods Totally 10 patients were implanted homograft to reconstruct right ventricular outflow tract,while 14 patients were implanted BalMedic from January 2003 to July 2009,and the function of the implanted conduit was evaluated by Doppler echocardiography one year after operation.Results 9 patients in group Homograft were cured,while 1 patient died of multiple organ failuie caused by infective endocarditis,which was confirmed associated to the conduit.13 patients in group BalMedic were cured,while 1 patient died of heart failure 2 days after operation,which no independent with the conduit.No stenosis of the pulmonary valve and further stoma had been found in both two groups,and they were no significant different( P ＞0.05 ).There were no thrombus aud aneurysm in both two groups.Two patients in group Homograft had low-grade regurgitation with pulmonary valve,while one had middle-grade regurgitation.And 4 patients in group BalMedic had low-grade regurgitation with pulmonary valve,no else became worse.Conclusion Both homograft and BalMedic can be used in reconstruction of right ventricular outflow tract.BalMedic may have better prospect.
