21.   Novoste has developed a catheter-based system similar to ones doctors use in balloon angioplasty.

22.   One hypothesis, then, is that the trauma of balloon angioplasty reactivates cytomegalovirus, which in turn, causes plaque to grow back in the artery.

23.   One trial will directly compare restenosis in patients treated by standard balloon angioplasty with that found in Rotablator patients.

24.   Other patients, he said, could be offered medical treatment or less invasive procedures like balloon angioplasty to open clogged vessels.

25.   Stents are used with balloon angioplasty, a procedure in which plaque build-up is dislodged by inflating a tiny balloon in the artery.

26.   Stents are used with balloon angioplasty, a procedure in which plaque is dislodged by inflating a tiny balloon in the artery.

27.   Stents help keep arteries wide after balloon angioplasty clears fatty buildup and restores full blood flow.

28.   Stents are usually implanted after balloon angioplasty, in which a small balloon-like device is threaded through the body to the site of a blocked coronary artery.

29.   Stents represent an alternative to balloon angioplasty because they remain open in the artery after the balloon catheter is inflated to dislodge the plaque build-up.

30.   The clogged artery was reopened by an increasingly common procedure called balloon angioplasty.
