Hello

Bsc in Cardiac technology or bsc in cardiopulmonary perfusion technology both are best career options and you will get good opportunities in that

But as per your query according to me you can do bsc cardiac perfusion technology because

in Cardiac technology you can assist physician in test but in Cardiac perfusion technology you can surgeon in surgeries.

cardiac perfusion technologist has greater salary package than cardiac technologist

cardiac perfusion technologist , surgeon and anesthetist are three main important person in surgeries.

after all that it totally depends on you you can work where you are really interested and enjoy your work.Both fields are good.

I hope this helps you
