Excimer,
Thanks for the interesting post.
I had never heard of this technique prior to your post, and thus the delay in my response. This is not a technique we use at CCF. I don't know what the reasoning is for not using it, but will find out tomorrow (9/15/03).
I can tell you that this technique is very new. There is only one report that I could find in a first tier cardiology journal. In fact, only 14 references were found by me in Medline.
The first tier report was the following:
"Comparison of effectiveness of excimer laser angioplasty in patients with acute coronary syndromes in those with versus those without normal left ventricular function.
Topaz O, Minisi AJ, Bernardo N, Alimar R, Ereso A, Shah R.
Cardiac Catheterization Laboratories, Division of Cardiology, Medical College of Virginia Hospitals, Medical College of Virginia, Virginia Commonwealth University, Richmond 23249, USA. ***@****"
This group looked at 100 patients. They were able to demonstrate plaque vaporization and improvement in blood flow. I did not see a description of improvement in angina symptoms. It might be worth emailing the address I listed above for further inquiry.
I hope that helps -- I'll try to comment tomorrow with additional information.

Conversations with the interventional cardiologists here at CCF indicate that they have a less than favorable impression of the laser technology for treatment of atherosclerosis.
They tell me that the restenosis rates are higher than that for simple balloon angioplasty. Most interventionalists think that this is because of the heat produced by the procedure.
They further tell me that this technology has been around since the early 1990s, and has not caught on despite extensive study.
Good luck.
