Cardiac cath can be safely performed
It must be done in borderline cases
to assess operability
Response of pulmonary vasculature
to pulmonary vasodilators like 02,
tolazoline and nitric oxide should be
assessed
Limit the use of contrast agent to
minimal

those of iron deficiency Phlebotomy may result in iron deficiency
anemia and cerebrovascular accidents
Discourage routine phlebotomy

Avoidance of Pregnancy• Pregnancy is absolutely

Eisenmenger Syndrome
Management of Pregnancy• Prolonged bed rest after 20th wks
gestation
• Oxygen therapy
• Digoxin and diuretics if CHF present
• Prolonged use of anticoagulants -
Heparin
• Careful monitoring of volume status,
oxygen saturation and hematocrit is
necessary

Is generally established by 2-4 yrs of age
Accelerated onset in Down’s, Cyanotic CHD
Median survival is 40-45 yrs of age
Anesthesia, surgery, dehydration poorly tolerated
Pregnancy carries 30-50% maternal mortality
Closure of the defect is detrimental once obstructive PAH has developed

ConclusionPatients with Eisenmenger syndrome can live upto fifth and sixth decades with informed medical care, patient education and protection from special risks 20% of death are related to avoidable errors
