The greatest danger to anyone with a failing heart that can only be treated with a transplant is that they will die before one becomes available.
Would it not be humane to allow people who have little or no chance of obtaining an human transplant that well may have dangerous viruses to have a pig one to see how real the problem is.
The chief concern seems to be that Porcine viruses could become endemic in the human sperm line but as yet there seems to be little evidence that this would happen from people who have received heart valves etc.
"A clinical trial study performed in 1999 sampled 160 patients who were treated with different living pig tissues and observed no evidence of a persistent PERV infection in 97% of the patients for whom a sufficient amount of DNA was available to PCR for amplification of PERV sequences. This study stated that retrospective studies are limited to find the true incidence of infection or associated clinical symptoms, however. It suggested using closely monitored prospective trials, which would provide a more complete and detailed evaluation of the possible cross-species PERV transmission and a comparison of the PERV "
This risk could be eliminated by sterilising recipients so that they cannot breed a small price to pay in return for the extra life a transport would bring.
