 Eisenmengers syndrome presents as a severe clinical picture of polymorbidity that constitutes a great burden at the individual as well as the familial and social level. The combination of critically increased pulmonary vascular resistance, progressive pressure load of the right ventricle and disturbance of pulmonary gas exchange result in long-term polymorbidity. While the patients ability to care for him- herself gets lost over time, the financial burden due to the need for medical consultations and hospital stays increases. This is distressing to both the patient and the family. Usually, death results from cardiac decompensation in the presence of gradually increasing pulmonary vascular resistance and hypoxic lesion of organs including the myocardium Hopkins, AJC 2002.
