Atrial septal defect and concomitant significant pulmonic stenosis in an adult patient
An adult male had persistent hypoxemia and erythrocytosis after repair of hemodynamically significant pulmonic valve stenosis. A large ostium secundum atrial septal defect was subsequently found as the cause of these symptoms. This sequence of events warrants review of his workup at his initial visit and follow-up visit and of the diagnosis and treatment of his pulmonic stenosis and atrial septal defect. The onset of new symptoms in an adult with a history of congenital heart disease indicates that additional cardiac evaluation is needed. This particular patient had an undiagnosed right-to-left shunt through an atrial septal defect.
