Hi there, Thanks for writing in. I am a qualified and certified cardiologist. I read your question with diligence. If your doctor has examined it and diagnosed it as right sided disease with no surgical option that makes it right side cardiomyopathy. Prognosis even at this stage is not all that gloomy. Please take whatever medicines which has been prescribed regularly. Keep the right legs slightly elevated put some thing for legs to rest while sitting down and a pillow beneath the ankles while lying down if it does not increase shortness of breath. Do not let him to injure his swollen feet as infection will produce more problems, avoid cold exposure. In addition, during winter months washing and maintaining good foot and leg hygiene is important. With these measures you can give much relief to the patient. Unfortunately, surgery is not panacea and if it is not feasible here that does not mean that other care would be less effective. Good Luck. With Best Wishes. Dr Anil Grover
