Is it? How?

Anyone please?

How?
Very carefully...

You can't actually bypass anything by catheterising it. You can unblock an artery and introduce a stent to keep it open, but a bypass is by definition a grafted section of vessel, usually harvested from the saphenous vein, that is cut and stitched in, just like building a bypass road.

Perhaps the question is whether there are less-invasive techniques than the traditional "open up your whole chest cavity" method?

Arguably feasible, but knife-and-fork CABG has been remarkably successful in this area so you would need to kill a lot of pigs and chimpanzees before inviting humans into a trial of anything else.
Which raises another interesting point. Butchers kill millions of pigs every day in order to provide food that humans are not evolved to digest and may even be carcinogenic, and nobody grumbles. Your local butcher is a good bloke, welcome in the pub and the cricket team.... But experimental surgery that could save human lives, raises howls of protest and death threats.

Your local butcher is a good bloke,
That's not a universal opinion (albeit, that it's a view I share).

Where did you get the 'humans have not evolved to eat meat' from?
I don't recall humans were forced to eat meat, by scarcity of vegetables or by any other reason.

We don't have the requisite teeth and claws for killing fresh meat, and are very prone to disease from eating carrion. No other animal needs to cook its food, and evolved carnivores such as dogs, cats and vultures have considerably stronger stomach acids in addition to their natural weapons.
It's no big deal. We weren't evolved to fly, and no other animal (apart from dung beetles) uses wheels. But it's worth bearing in mind when looking at the ethics of killing.
