Eur Heart JPublished

  • Systematic review and meta-analysis of observational studies
  • prespecified protocol

Authors' conclusion

Screening family members of people with BAV can identify a cohort substantially enriched for the presence of bicuspid valve, aortic enlargement, or both.

Study context

Population
First-degree relatives of people with bicuspid aortic valve (BAV) screened for BAV and aortic dilatation
Participants
6,054 relatives · 23 studies
Outcome
Screened prevalence of BAV and aortic dilatation among relatives

Pooled result

As reported in the abstract

Prevalence of BAV among relatives, overall

7.3% (95% CI 6.1%-8.6%)

Prevalence of BAV per family

23.6% (95% CI 18.1%-29.5%)

Prevalence of aortic dilatation among relatives

9.4% (95% CI 5.7%-13.9%)

Further pooled results

Aortic dilatation prevalence by relative's valve type (subgroup)

Relatives with BAV
29.2% (95% CI 15.3%-45.1%)
Relatives with tricuspid valves, higher than in the general population
7.0% (95% CI 3.2%-12.0%)
Aortic dilatation with tricuspid valves more frequent overall, as many more relatives had tricuspid valves
