What
is it? |
A cardiac ablation catheter is a long,
thin tube that is threaded into or onto the heart to destroy
(ablate) an area of heart tissue that is causing abnormal
heart rhythms. |

When
is
it used? |
Cardiac ablation catheters are
used to treat abnormally rapid heartbeats that cannot be controlled
with medication, or in patients that cannot tolerate these medications.
They are used most often to treat abnormal rhythms that begin
in the upper heart chambers (atria). Some examples are:
- Supraventricular tachycardia (SVT)
- Atrial Tachycardia
- Atrial Flutter
Less often, ablation can be used to treat heart rhythm disorders
of the lower heart chambers (ventricles).

How
does
it work? |
The cardiac ablation catheter
is inserted into a blood vessel (artery or vein), usually
through a site in the upper leg or neck. The tube is advanced
through the blood vessels until it reaches the heart. The
catheter is navigated by images created by fluoroscopy –
a type of x-ray machine.
In the heart, electrodes at the catheter tip gather data
that pinpoint the location of faulty tissue in the heart (electrical
mapping). Once the site is identified, the device delivers
either radiofrequency energy (RF ablation) or intense cold
(cryoablation) to destroy the small section of tissue. |

What
will it accomplish? |
Cardiac catheter ablation is a
relatively non-invasive procedure that can restore a normal
heart rhythm. It can eliminate the need for open-heart surgery
or long-term drug therapies. |

What
are
the risks? |
During catheter insertion,
the heart or a blood vessel may be perforated or damaged.
Other potential complications include interruption of normal
impulse conduction, stroke, heart attack, and death.
Your doctor will tell you more about the risks associated
with cardiac ablation. |

When
should
it not be used? |
Catheter ablation should not
be used in patients who have a blood infection or in patients
who can not tolerate certain catheter placement approaches.
