Des Plaines, IL --According to IMV's recent census of cath labs in the U.S., an estimated 3.75 million patient cases were performed at 2,020 cardiac cath lab sites in 2008, including both cardiac and non-cardiac patient cases.

Between 2002 and 2006, cath lab patient cases increased about 9% from 3.85 million to 4.21 million, for an average annual growth rate of about 2% per year over the period. However, starting in 2007, the total number of patient cases declined about 10% from 4.21 million in 2006 to 3.80 million in 2007, with a slight decrease of 1% to 3.75 million in 2008.

"This slowdown in patient cases handled by cath labs is due to the convergence of several factors that have primarily affected both diagnostic and therapeutic coronary cases," observed Lorna Young, Senior Director, Market Research at IMV.

"With the advent of CT coronary angiography procedures (CTA), the volume of diagnostic cath procedures appears to have declined. It is possible that a controversy in the use of drug eluting stents that developed in 2005/06 resulted in a reduction in therapeutic coronary cases. In addition, the increased use of pre-authorization policies by third party insurers may be at play. Taken together with the current economic downturn, the market for cath lab purchases will be slow over the next few years."

"However, the cath labs are not standing still. At the same time that coronary case volume has slowed, we are seeing increased volume of other types of cardiac procedures between 2006 and 2008, such as electrophysiology procedures and cardiac device placements being performed in the cath lab, as well as an increase in non-cardiac cases, such as carotid, iliac, femoral, run-off, renal and extremity studies. And going forward, 25% of the cath lab sites are planning to purchase intravascular ultrasound systems, which is up from five years ago."

IMV's 2008 Cardiac Cath Lab Market Summary Report describes trends in patient cases, cath lab imaging systems, diagnostic review stations, electrophysiology, intravascular ultrasound, hemodynamic systems, device utilization, contrast
media utilization, power injectors for cath contrast, capital and consumables budgets and site operations characteristics.

Highlights include:
-38% of the cath lab sites had one room, 35% had two rooms, and 27% had three or more rooms.
- At least 89% of the planned cath lab purchases over the next three years will have flat panel image digital detectors.
-The proportion of cath labs having dedicated electrophysiology rooms in the department has increased from 23% to 33% over the past decade.
-In addition to cardiologists performing non-cardiac cases in the cath labs, endovascular surgeons are the second most likely to be performing non-cardiac cases in cath labs, doing so at 35% of the sites, and interventional radiologists are performing non-cardiac cases in 18% of the cath lab sites.
