A US man has become the first person in the world to get a generic viagra cheap heart transplant from a genetically-modified pig.
David Bennett is doing well three days after the experimental seven-hour procedure in Baltimore.
The transplant was considered the last hope of saving Mr Bennett’s life, though it is not yet clear what his long-term chances of survival are.
Doctors at the University of Maryland Medical Center were granted a special dispensation by the US medical regulator to carry out the procedure, on the basis that Mr Bennett would otherwise have died.
