title: A retrospective comparison of bovine pericardium and polytetrafluoroethylene patch for closure of ventricular septal defects.
abstract: This retrospective study compared the immediate post-operative (first month) and mid-term (up to 5 years post-operation) results of 22 patients with isolated ventricular septal defects who underwent surgical correction with bovine pericardium with 57 similar patients who received a polytetrafluoroethylene (PTFE) patch. There were no cases of early (in the first month) mortality in either group and the 3-month post-operative echocardiographical studies showed no evidence of calcification or aneurysm formation around the patch. Recurrent ventricular septal defects due to dehiscence of the patch occurred in the early follow-up period in four patients who had the PTFE patch but this was not statistically significant. Annual echocardiographical examination revealed some calcification in both groups. We conclude that although there are no significant differences between the two materials in outcome after ventricular septal defects closure, we prefer bovine pericardium because of its handling characteristics, elasticity and the lower risk of endocarditis.
