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: no population prevalence; any figure shown is a proxy (incidence, registry proportion or criteria positivity). 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.

The landmark trials in each condition, drawn to the same kind of scale by number of participants: Key studies.
