Eisenmenger Quality Enhancement Research Initiative

Approximately 200 male and female adult patients with a history of Eisenmenger will be
recruited from approximately 50 cardiology practices over a period of 18 months and will be
followed up every six months for the period of three years. Consecutive patients in each
practice meeting inclusion and exclusion criteria should be considered for the study.
Participating sites will be asked to maintain a screening log to identify which inclusion or
exclusion criteria was not met thus excluding them from the study.

Inclusion Criteria:

- Male and female patients

- Diagnosis of Eisenmenger syndrome based on right heart catheterization data

- Right to Left intra-cardiac shunting

- PAH

- Need for comprehensive management according to guidelines and peer-reviewed evidence

- Ability and desire to execute the consent for follow up

Exclusion Criteria:

- Poor mental function, drug, or substance (e.g.,alcohol) abuse, or unstable psychiatric
illness, which, in the opinion of the investigator, may interfere with optimal
participation in the study

- Prior inclusion in this program
