• Age 16 years onwards• ~ 85% survival to 16 years (better medical and 85% survival to 16 years (better medical and surgical therapies over the past 20 years)

l l i• Prevalence 3.2 per 1000 population• The ACHD population in Wales is currently p p yestimated at 8,500 (~185,000 in the U.K)
• The ACHD population is expected to expandThe ACHD population is expected to expand at a rate of ~ 10% per year
• So GPs and secondary care physicians will start• So GPs and secondary care physicians will start to see more pts with ACHD.
• Plus, many ACHD patients wish to start a family...

Complex:Complex:e.g. Single ventricle e.g. with Fontan‐type palliation,p

Initial Management of Congenital Heart Disease
• Aim = to restore cardiac anatomy to as near normal as possible at as early an age as possible (i.e. as neonates/infants).
• Many patients undergo correction of the defect(s) e.g. ASD closure.
• Some disease is so complex e.g. a single ventricle that palliative surgery is the only option, which leaves the patient with gross anatomical distortions.
• Occasionally defects are not operable due to complexity or irreversible pulmonary hypertension at ti f di itime of diagnosis.

ACHD managementACHD management
ll i h ld b d l b• All patients should be assessed at least once by a specialist in ACHD and a management plan f l t dformulated
• Currently Dr Dirk Wilson, Dr Nav Masani, myself (Dr Helen Wallis) aim to provide a ACHD service across SW but as yet there is no full time ACHD
i li i W lspecialist in Wales. • A few patients will be discharged with advice, most will require lifelong FU.
• Correction of a defect does not equate to a ‘cure’.q

• The right ventricle is the systemic ventricle i.e. has to pump blood around the body
• The RV is not designed to cope with high pressure, therefore, over time the RV dilates andpressure, therefore, over time the RV dilates and then function declines
