Intracardiac Ultrasound (ICE)
Why
is the doctor performing this test?
To view the
inner lining of the heart, including the heart valves. Intracardiac
ultrasound allows detailed evaluation of the inner surface of the heart and
valves to determine if there is abnormal anatomy, vegetation (infection),
or any abnormalities of the inner lining of the heart. Sometimes intracardiac ultrasound is used during other
cardiovascular procedures (such as pulmonary vein ablation or atrial septal closures) to
provide constant monitoring of the heart structures and pulmonary blood
flow throughout the procedure.
What
is the test?
Intracardiac ultrasound is an invasive diagnostic test
using a catheter with a sound transducer (or sound probe) on the end. The
catheter is threaded thru the vein in the groin and up into the heart.
High-frequency sound waves are used to create precise images of the
interior heart surface. The catheter with the ultrasound tip attached is
carefully removed, and then pressure is applied over the groin area to stop
any bleeding.
Where
is the test performed?
In the
Cardiac Catheterization Lab.
How
long does this test take?
Intracardiac ultrasound usually takes thirty to sixty
minutes.
