A Unique Case of Eisenmenger Syndrome Treated With Interventional Surgery.

Atrial septal defect (ASD) is a common congenital heart disease. According to previous views, once Eisenmenger syndrome develops, the opportunity for surgical treatment is lost. This article reports a case of ASD combined with pulmonary valve stenosis (PS) in a patient who had experienced right-to-left shunting through the ASD for 40 years. What distinguishes this patient from other Eisenmenger syndrome patients is the presence of severe PS. We attempted to first relieve the severe PS and then perform ASD closure. Ultimately, the patient benefited from surgical treatment.
