System. You will be given a detailed description of the procedure, your
doctor will discuss the risks associated with the procedure and the
Sensor, your doctor will respond to any questions you have, and you
will be asked to sign an informed consent.
Inform your doctor of any infections, arrhythmias, or bleeding that
occurs before the implant procedure.
The Implant Procedure
During a right heart catheterization, the Cordella Sensor is
permanently implanted in a blood vessel that carries blood from the
heart to the lungs. This catheterization is a standard procedure used
to measure the pressures in the heart and PA.
The Cordella Sensor is the length of a $0.01 coin (19.3mm x 3.8mm x
1.9mm) and has two wire loops extending off either end which hold it
in place in the vessel. The Cordella Sensor is tied down on a catheter
that is skillfully navigated to your PA by your doctor.
The steps of the implant procedure are:
1.
You may be mildly sedated to start but your doctor will likely
need you awake during certain parts of the procedure to
follow instructions.
2.
A nurse will clean the access site and will numb it with a local
anesthetic.
3.
You will be monitored by an electrocardiogram with sensors
on different areas of your body to measure electrical activity
of your heart. These patches will be attached to wires to
monitor your heart during the procedure.
4.
Once the anesthetic has numbed the access site, your doctor
will make a small incision and insert a small tube called a
pulmonary catheter. The pulmonary catheter will be
threaded through your vein while your doctor looks at a
screen with a live x-ray
—
called a fluoroscope
—
of your veins
and heart. Your doctor will navigate this catheter through
your veins to your heart and then to your PA.
5.
Your doctor will take a few pictures with the fluoroscope at
this point by injecting dye through the end of the catheter
that is still outside your body. These pictures will give your
