My uncle been feeling breathless since 2 weeks. We got eco and other essential tests done. We got notified that his heart is enlarged and a bit weak and is working to 20%-25% of it's ability. And also his one artery is blocked and has leakage. He's 35 and has no BP or diabetes issue. We're very concerned. We got to many doctors some say surgery is the best option, other say surgery is risky to death as heart working rate is low and condition is very critical. Please suggest the right option.
