Electrophysiology Study / Catheter Ablation
Explanation of procedure.
The aim of the procedure is to look for any abnormal heart rhythms or abnormal electrical
pathways within the heart and in most cases use heat or cold to kill off destroy the area
involved. It is performed using thin tubes inserted into the blood vessel/(s), usually at the
top of your leg, through which fine wires are passed up into your heart with the help of Xrays. Once in the heart these wires are used to bring on your palpitations try to start the
abnormal rhythm so that any abnormal area can be found. Sometimes medication is given
through a drip in your arm to help try and start up your palpitations speed up the heart.
Once the abnormal area is found it can be destroyed using hot or cold energy delivered
down a special wire also slid up inserted into the heart, usually through the same blood
vessel.
The intended benefits of this procedure
To test for abnormal heart rhythms
To treat your identified abnormal heart rhythm
Serious or frequently occurring risks:
Less than 1 in 100 risk of serious or life threatening complications such as:
 blood clots which could cause a stroke or heart attack;
 puncture of the blood vessels or heart wall which could lead to a collection of blood
in the sac surrounding the heart and which could lead to an emergency operation to
repair.
Less than 1 in 100 risk of needing a permanent pacemaker due to unintentional damage to
the conduction system in your heart.
1-5 in 100 risk of bruising or swelling (false aneurysm) where the wires have been
removed from the vein after the procedure.
5-10 in 100 risk of having to undergo a re-do procedure if radiofrequency (heat) energy is
used
10-15 in 100 risk of having to undergo a redo procedure if cryo (freezing) energy is used.
Any extra Additional procedures which may become necessary during or after the
procedure:


Transeptal puncture. Passing a wire through the thin muscle wall between the top
two chambers of the heart in order to reach the left hand side of the heart.
Pericardiocentesis. Removal of blood from the sac surrounding the heart if a
puncture of the blood vessels or heart occurs.
I have discussed what the procedure is likely to involve, the benefits and risks of any
available alternative treatments (including no treatment) and any particular concerns of this
patient. (as per other forms)
