QUOTE: what is inferoseptal wall ischemia and what are the treatment here
>>>>The septum is the wall that separates the right and left heart chambers. Ischemia is the medical term for a lack of blood flow. So your question is stating there is reduced blood flow the septum and inferoseptal is the location of the lack of blood flow.
Treatment would be to open a pathway for a better blood supply, medication, etc. Or the condition may not be any problem depending on the degree of occlusion and area deficit of blood oxygen.
Hope this answers your queston, and if you have any followup questions you are welcome to respond. Take care.
