Background: Despite fears of compromised oxygen delivery in patients with Eisenmenger syndrome during flight on commercial aircraft, a clinical study has shown no adverse effects, and many patients travel frequently.
Methods: The air travel history over the past decade of 53 patients with Eisenmenger syndrome and 48 acyanotic patients was obtained. Patients listed all flights and destinations, and any major adverse event or symptoms, including, specifically, headache, palpitations, oedema or need for supplemental oxygen.
