How Is Eisenmenger Complex Treated?

Eisenmenger Complex is often diagnosed when a patient reports with a distinctive heart murmur, cyanosis, hypertrophy (thickened walls) of the left ventricle, enlarged pulmonary artery, and/or a somewhat enlarged heart. The patient will be examined through the use of electrocardiography (producing an ECG, or electrocardiogram), chest x-ray, and/or echocardiography (producing an echocardiogram). Angiography may also be used in some cases, but is usually avoided because it may be unsafe for patients with PVOD. In some cases, a cardiac catheterization procedure may be necessary to determine the size of the VSD and to take measurements in the heart.

Surgical closure of the defect may benefit some patients. The repair of large VSDs in infancy is the best way to avoid the development of Eisenmenger Complex. This is currently done whenever possible. However, in the past VSD closure was often deferred and excessive pulmonary blood flow was checked by the insertion of a band around the pulmonary artery. Once pulmonary hypertension has developed, it cannot be reversed and VSD closure is often not an option as the mixing of blood it allows is necessary to ensure adequate cardiac output.
