MS-0401

A 2-year-old toddler is brought to the cardiology clinic by her mother due to concerns of episodes of turning blue, especially when laughing or crying. During the examination, the toddler is observed to have clubbing of the fingernails and confirmed to be cyanotic. Further investigation with an echocardiogram reveals a large ventricular septal defect, leading to a diagnosis of Eisenmenger’s syndrome. What is the ultimate treatment for this condition?
