Hi, its abhishek here, we recently found that my dad's got a hole in the heart. His age is around 50 now and we are extremely worried and concerned about the same. What should be the ideal course of action? Now i realise that the symptoms have been visible for quite a while now. He easily gets short tempered & gets angry in a whiff. Please help me out in the same.
