Which of the following represent features of a stent and its use in cardiology? Check all of the boxes that apply.

It is delivered to the heart through a catheter, a long, thin tube, and this procedure can avoid major bypass surgery. Stents are generally left in the body, so F is incorrect; they also typically allow a faster recovery than bypass surgery, making C incorrect.
