What Other Terms are Used to Describe Percutaneous Transluminal Coronary
Angioplasty?
- Balloon Angioplasty
- Angioplasty
- PTCA
Why is an Angioplasty Done?
- A PTCA is a procedure that opens narrowed arteries to
increase blood flow.
- A PTCA may be done instead of coronary artery bypass
surgery depending upon the type and location of the narrowing, the extent of the disease
and the risk involved.
- The rate of restenosis (renarrowing) is 25-80 % within
the first six months.
How is A Balloon Angioplasty Done?
- This procedure is nonsurgical and is performed under
X-ray guidance in the Cardiac catheterization lab.
- A PTCA may be done immediately following a cardiac
catherization or sometime later.
- The patient is given a mild sedative to help him relax
but remains awake during the procedure to allow him to answer questions regarding his
comfort level, any chest pain or shortness of breath.
- A small area of the groin or arm is shaved and cleaned
where the catheter is inserted.
- Medication is used to anesthetize (numb) the area so a
small incision can be made where the catheter will be inserted.
- A catheter with a deflated balloon on the tip is
inserted through the artery in the groin or arm. X-ray is used to guide the catheter up
into the heart.
- The catheter is threaded up into the narrowed artery of
the heart. The balloon is then inflated and deflated several times to squeeze the plaque
deposits against the wall of the artery.
- The test takes 1-2 hours.
What Symptoms May be Experienced During the
Procedure?
- A slight burning or stinging from the medicine used to
numb the catheter insertion site.
- Slight discomfort or pressure as the catheter is being
inserted.
- Slight nausea and or, extra heartbeats.
- Chest pain may occur as the balloon catheter is being
inflated, but it is temporary.
What Happens After the Procedure is Completed?
- After X-rays are taken, the balloon and catheter are
removed, but the sheath (IV) will remain in place.
- A sheath (IV) is usually left in place in the leg
overnight until the blood thinning medications are discontinued and your clotting time
returns to normal.
- A bandaid or pressure dressing will be placed over the
area where the catheter was inserted.
- You will be admitted to a special cardiac care unit
(POU or ICCU) to monitored closely.
- When the sheath is removed from the groin firm pressure
is applied to the sheath insertion site for 15-30 minutes until the bleeding stops.
- If an artery in the arm is used, pressure will be
applied over sheath insertion site for 15-30 minutes also.
- The insertion site will be checked frequently for signs
of bleeding.
- Blood pressure and the pulse in the leg (or arm) used
will be checked frequently.
- A knot may occur under the skin where the catheter was
inserted. This is only temporary.
- Bruising may occur in the area of the leg/groin where
the catheter was inserted and may spread down the leg and is only temporary.
- Most patients are discharged 8 hours after the sheath
is removed with minimal activity restrictions.
What
Precautions Should Be Observed Following the Procedure?
- Avoid bending the leg at the hip (groin area) for 6-8
hours after the catheter is removed.
- Hold the bandaid firmly if you need to cough or sneeze.
- Avoid bending or using the arm for several hours if it
was used for the insertion of the catheter.
What Signs and Symptoms Should Be Reported Immediately?
- Discomfort or sudden pain at the insertion site.
- A warm, moist and sticky feeling, or bleeding.
- Any discomfort in chest, neck, jaw, arms or upper back,
shortness of breath, weakness or dizziness.
What Follow Up Can Be Expected?
- The patient will continue to have routine follow-up
visits with the cardiologist after this procedure.
What Preparation is Needed?
- Nothing to eat or drink after midnight.
- It is important for the patient to ask his doctor:
- How to adjust insulin and food intake prior to the test
if he is a diabetic
- If he should take his regular medications the morning
of the test
- If taking blood thinners (ie. Coumadin), should they be
withheld and, if so, how long prior to the procedure
- Leave all valuables at home.
- Plan to be admitted to the hospital overnight.
- Make arrangements to be driven home the following day.
