The Heart Center at St. Rita's Medical Center operates two cardiac
catherization labs and is currently building a third, which is scheduled to
open in the summer of 2004. Staffed with highly qualified nurses and physicians,
cardiac catherizations are done to determine how well the heart muscle, heart
valves and coronary arteries are functioning. The catheterization is done to
precisely identify a problem that may have been indicated in previous tests.
During the procedure, a very thin tube (catheter) is inserted
into an artery in the groin and threaded into the heart. Once in place, a dye
is injected into the arteries of the heart. The flow of the dye throughout
the heart and coronary arteries is recorded so the physician can determine
the function of the heart muscle, the flow of blood through the heart valves
and the presence of any narrowing of the coronary arteries that nourish the
heart muscle. The catheter can also measure the pressure of blood pumped by
the heart. With this information, the physician can prescribe the proper treatment
for any abnormality found.
Coronary angioplasty, stent placement and rotoblation all involve
placing a catheter into the groin and threading it into the specific artery.
An angioplasty uses a balloon threaded through the catheter and inserted into
the narrowed artery. The balloon is inflated to open up the blocked area and
smooth the material (plaque) back against the wall of the artery.
A stent is a small metal tube inserted into the narrowing of
an artery and expanded to further push open the artery and help keep it open.
This is used when the material (plaque) in the artery is rough and does not
smooth down. Some newer stents are coated with a drug that is used to help
prevent a blockage from forming. These are called drug eluting stents and your
particular clinical situation will determine if a drug eluting stent is warranted.
Rotoblation is used to burrow through hard rough plaque and is
often followed with angioplasty and/or a stent to smooth down the hard material.
All procedures performed in the cardiac catherization lab are
safe and relatively painless although some discomfort may be present once the
procedure is finished. Procedures are performed under a local anesthetic so
the patient will not feel anything. The cath lab is backed by the complete
medical care provided by St. Rita's Medical Center if complications should
occur.
