Like angioplasty, coronary stents (a stainless steel mesh tube) physically
open the channel of diseased arterial segments, relieve the recurrence
of chest pain, increase the quality of life, and reduce other complications
of heart disease.
Coronary stenting opens up the diseased segment into a rounder, bigger
and smoother opening compared to
angioplasty, producing a more predictable and satisfactory result. Stents can also
keep an artery open that was torn or injured during angioplasty, and decreases
the chance of recurrence of the blockage (restenosis) by nearly 50 percent.
Since it is performed through a needle-sized hole in the groin or the arm,
(called a “percutaneous procedure”) it is much less invasive
than surgery, and can be repeated should the patient develop disease in
the same, or another, artery in the future.
