How is Eisenmenger’s syndrome defined?
pulmonary HTN with reversed or bi-directional shunt. (end pathology for uncorrected congenital heart defects)
what are some signs and symptoms of Eisenmenger’s?
DOE Palpitations Syncope Cyanosis Angina Hemoptysis Systolic murmur
what are the 3 main shunt locations for patients with Eisenmenger’s?
Aorta (aortico-pulmonary septal defect)
Atrial (total anomalous pulmonary return)
Ventricular (VSD, Tricupid atresia, PS)
describe the course of development in terms of pathophysiology?
L -> R shunt
Increased PVR and Pulmonary HTN
R -> L shunt
