60 year old fairly fit male. now all 4 of my heart valves are leaking severely, my heart is enlarged now to push more blood. my heart is performing at a 20% capacity. all this seem to come on suddenly when I started to struggle for oxzgen. what are the normal procedures medicaly that probably will take place
Simultaneously leaking all four valve and that too severe, is very unlikely, mostly you had dilated cardiomyopathy leading to separation of valve leaflets which are normal and sever leak. So medication should help.  However, if still in compensated because you are fit surgical replacement is the treatment of choice, mostly they would replace mitral and aortic.  Also, as I said your understanding of your heart condition is not adequate.  You may send me the 2 d echo report and I would be able to guide you better, you may send a direct query to me @ Chat Doctor.  Hoping I could help, regards
