What is considered a large ASD?

In this video, Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks, will explain about large ASD. A small ASD of less than 6mm can wait for 5 years for its spontaneous closure. Moderate ASD is 6-8 mm in diameter and large ASD is more than 8 mm in diameter. Large ASD usually requires correction as it will not close spontaneously.
