Prevalence of inherited cardiac conditions

Circle area is proportional to prevalence in the general population; a range is drawn at its midpoint; circles that would fall below 6 px radius are drawn at 6 px.

Dashed circles carry a figure that is not a population prevalence (an incidence, a proportion of a registry, or criteria positivity), or none; bicuspid aortic valve, at 1–2% of the population, is not drawn.

Figures are the ones quoted on each condition page and derive largely from referral cohorts and registries.
