Bovine (group B) and porcine valves (group P) were used in 342 and 199 patients, respectively. The median follow-up duration was 4.1\u2009years [interquartile range 1.2\u20139.0]. Inverse probability of treatment weighting analysis was performed for adjustment between the groups. Early and long-term clinical outcomes, including all-cause mortality, ischaemic stroke, haemorrhagic stroke, endocarditis and reoperation, were compared.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>In inverse probability of treatment weighting analysis, operative mortality and early clinical outcomes were comparable between the groups.

The cumulative incidence of cardiac death, ischaemic stroke, haemorrhagic stroke and endocarditis also demonstrated no significant differences between the groups (28.1% vs 25.9%, 7.1% vs 1.2%, 3.2% vs 4.2% and 9.7% vs 6.0% at 5\u2009years in group B versus group P, respectively).
