Heart Surgery in India
A new preventative treatment for heart attacks could cut repeat problems in
victims and save lives, doctors believe. In heart operations, patients are usually fitted with a stent - a thin mesh
tube - in the artery that triggered the heart attack to restore the blood flow,
a treatment known as angioplasty.
It is common for other arteries to narrow in heart attack patients. Under
the new technique, all narrowed arteries are opened with stents to prevent
future problems. Medical guidelines recommend that specialists only treat the
artery which is blocked.
The preventative technique found that patients with stents placed in all
narrowed arteries were 64% less likely to die, suffer another serious heart
attack or have severe angina over the next two years. The trial involved 465
patients in four specialist heart units between 2008 and this year.
Currently, following a heart attack, patients undergo an emergency operation
called an angioplasty. During this procedure a stent is inserted into the
blocked artery to restore normal blood. However, around half the patients also
have significant narrowings in other arteries which could cause another heart
attack in the future. The trial showed some of the most striking results for a
treatment that I have ever seen. The results of this trial really challenge
clinical practice.
Heart specialists want a larger study to further test the new treatment. The
trial shows very clearly that patients have a much better outcome if these
other narrowed arteries are stented at the same time as the one that triggered
the attack. This strategy is also much more cost effective for the health
service.
Interventional Cardiology Procedures for HeartDiseases
Stents
- Approximately 70% of angioplasty procedures
also involve stenting, which is the insertion of a small metal cylinder called
a stent into a blood vessel. In this procedure, a collapsed stent is placed
over the balloon at the tip of the catheter. When the balloon inflates, the
stent pops open and reinforces the artery walls. The balloon and catheter are
then withdrawn and the stent inside permanently. In a few weeks, tissue from
the artery lining grows over the stent.There are two types of stents.
Bare-metal stents are plain, untreated metal cylinders. Drug-eluting stents
(also called drug-coated stents) are coated with medication before they are
placed in the artery.
Balloon
Angioplasty - Balloon Angioplasty is a
procedure in which a narrowed heart valve is stretched open in a way that
does not require open heart surgery.It is a procedure in which a thin tube
(catheter) that has a small deflated balloon at the tip is inserted through
the skin in the groin area into a blood vessel, and then is threaded up to
the opening of the narrowed heart valve. The balloon is inflated, which
stretches the valve open. This procedure cures many valve obstructions. It is
also called balloon enlargement of a narrowed heart valve.

Rotablation (Percutaneous Transluminal Rotational Atherectomy or PTRA) - A special catheter, with an acorn-shaped, diamond-coated
tip, is guided to the point of narrowing in the coronary artery. The tip
spins around at a high speed and grinds away the plaque on the arterial
walls. This process is repeated as needed to treat the blockage and improve
blood flow. The microscopic particles are washed safely away in your blood
stream and filtered out by your liver and spleen.

Drug-Eluting Stents - A drug-eluting stent (DES) is a coronary stent (a
scaffold) placed into narrowed, diseased coronary artery. It slowly releases
a drug to block cell proliferation. This prevents fibrosis that, together
with clots (thrombus), could otherwise block the stented artery, a process
called restenosis. The stent is usually placed within the coronary artery by
an Interventional cardiologist during an angioplasty procedure.
