In future, please set out your work as I have done below. If you don't, it makes it difficult for us to check.

Once a valve is damaged beyond repair, as happens with recurrent attacks of a rheumatic fever, the only way to save the patient would be to replace it.
Almost all replacements ……(used are?) ……(do) today using mechanical devices. Among the earliest ……?……(be) the ball-and-cage valve which was invented in 1961 by Albert Sterr, a surgeon of Portland, Oregon, USA and his collaborators M. Lowell Edwards. It had a plastic ball in a stainless steel or titanium cage. But the device had several disadvantages. The presence of the ball caused severe turbulence and cavitation which also caused damage to red blood cells leading to the risk of clot formation. It was therefore necessary to put the patient on a long term anticoagulant therapy.

Once a valve is damaged (correct) beyond repair, as happens with recurrent attacks of a rheumatic fever, the only way to save the patient, would be (possible, but there is a much more likely answer) to replace it.
Almost all replacements ……(used are?)…(You haven't used part of the verb given)…(do) today using mechanical devices. Among the earliest ……?……(be) the ball-and-cage valve ...

The others are correct.

Thank you

vivekp, I have inserted your suggested answers into the paragraph which, as we said, makes it much easier to read than just a list of answers. They are all correct except the two I have marked in red which, whilst not wrong, are not (in my opinion) the best choice. As 5jj said in his first response, "would be" is "possible but not the most likely choice". What else could you put there?
