Something to think about... While the below research may be 5 to 10 years away or may not pan out as still very early in it's testing, this is likely the future and will be here sooner than later... I am also aware of another stem cell project that is similar which will likely replace the need for pacemakers and the accompanying surgery. It is my understanding the pacemaker procedure may be made available within the next five years as they are just beginning human studies but have had very good success so far...
