Undiagnosed ventricular septal defect with resultant Eisenmenger syndrome presenting with diplopia

Ventricular septal defect (VSD) is the most common congenital heart lesion among children. In most cases, however, it is identified and corrected in childhood, before long-term sequelae such as pulmonary hypertension develop. In this case report, we present a young man with an undiagnosed VSD with consequent Eisenmenger syndrome who initially presented to medical attention with diplopia found to be caused by cerebral infarcts.
