Do I have option other than organ transplant?

This query can only be answered by the treating doctor depending upon medical condition and stage of damage of the organ. For example in a case of kidney failure, dialysis is an alternative treatment and for kidney failure patient transplant is usually not an emergency. Also, for a heart failure patient, some patients can be maintained on artificial cardiac assistive devices. Similarly for other organs criterias are different, that can be maintained on medical therapies for the time being.
