Because of its compatibility with human body. The research is decades old, For centuries humans knew there are lot of similarities in various systems of human body with pigs.The question is that why, out of all animals, pig's heart suits human being, as a transplant?
This is a new question before the Ummah and there needs to be a discussion and a consensus on that matter. My personal take is that it is not halal to put it in your stomach, how come it becomes halal to put it in your chest and mix its blood with your blood.
Instead of pig, if there was a goat heart, that may be a more acceptable option.

Its beauty of nature. Science is only the tool that goes with facts.
There shouldn't be any religious discussion on scientific matters. Already we have eaten ourselves and we are doomed because of unnecessary fatwas. If we had qualified "ulemas" who are well versed in religions and at the same time pHds in sciences, they would never get us into such nonsense fatwas. Its clearly mentioned only eating is prohibited and even that is allowed as a medicine (if neccessary). Why need discussion for totally scientific & medical stuff.. religion shouldn't be dragged into it.
..... alcohol has no benefit nutritionally and causes organ failure
It is a new incident with no history in science or religion and second, it is about a haram animal. There should be discussions to understand what is Islamic guidance on this matter.
Take another example if you may, if you lose your tooth, will you put a pig's teeth in your mouth, or pig's tongue replace your own? How about injecting pig's blood into your veins along with your own? This sounds wrong, doesn't it? Since Muslims do not eat pigs, my take is most wouldn't be willing to accept any of its body parts.
Now between you and me, there is a difference of opinion and we're discussing. The same discussion is required at the country level and collectively at the Ummah level. You are right that qualified Ulemaa would be required to make a call on it and as Allah Kareem has said that Ummah wouldn't be wrong as a whole, it is a glad tiding for us and we can rely on the collective conclusion of Ummah Alhamdolillah. May Allah help us make the right call on it.
Dragging religion in scientific & medical discoveries is the recipe for disaster.
Secondly, the argument for tongue or teeth isn't valid as its not for life saving. That particular patient couldn't get a human heart transplant. Only option was genetically modified pig's heart. It was die or live using pig's heart. Its experimental procedure with no guarantee for longevity. But medical community and we hope it works as it can save countless lives. Any sane person will not find excuses or fatwas at this point where there is no other option at all. Humans doesn't require religion for common sense, The discussion would have had any point if the transplant is non-life saver. For example hair transplants, some beautification and you are getting PIG's parts then yes you may do discussion on whether its Haram or Halal. But for life-saving procedure and only option... there is no point at all for any discussion. Can religious community or Fatwa producers will offer any other alternative to dying person ?. Can their Dam / darood / Dua's will give guarantee to dying person that he won't die ?... Nope!.. Be practical!. Embrace science & technology with open hands.
