Situs inversus: understanding Catherine O’Hara’s mirrored anatomy

The Washington Post WellBeing piece explains situs inversus, a rare condition in which internal organs are mirrored from their usual positions. Catherine O’Hara was born with it, a condition sometimes manifested as dextrocardia (the heart on the right side). For most people with situs inversus, there are few or no symptoms and the condition is often discovered incidentally, with health implications varying depending on any associated anomalies.
