Device That Clears Debris From Artery Aids Blood Flow in PCI
Date:3/30/2008

Better clinical results with Export Aspiration Catheter hold up at one year

CHICAGO, March 30 /PRNewswire/ -- Use of a special catheter that sucks out, or aspirates, bits of plaque and blood clot that break loose during percutaneous coronary intervention (PCI) significantly enhances blood flow deep in the heart muscle in patients who are experiencing a heart attack, according to a recently published study. Now, a new analysis of the Thrombus Aspiration during Percutaneous Coronary Intervention in Acute Myocardial Infarction (TAPAS) study has shown that the link between deep myocardial perfusion and better clinical outcomes that was apparent at 30 days is still strong after one year.

The one-year results of the TAPAS study, which focused on patients suffering from a type of heart attack known as ST-elevation acute myocardial infarction (STEMI), are being reported today in a Late-Breaking Clinical Trials session at the SCAI Annual Scientific Sessions in Partnership with ACC i2 Summit (SCAI-ACCi2) in Chicago. SCAI-ACCi2 is a scientific meeting for practicing cardiovascular interventionalists sponsored by the Society for Cardiovascular Angiography and Interventions (SCAI) in partnership with the American College of Cardiology (ACC).

PCI is considered the best treatment for STEMI when it is delivered in a timely fashion by experienced clinicians, because it can rapidly and reliably open an artery on the surface of the heart that has been blocked by a blood clot. However, bits of atherosclerotic plaque and blood clot can break loose during angioplasty and stenting, traveling downstream to occlude the tiny vessels, or microcirculation, that supply blood deep into the heart muscle. When this happens -- even if the surface artery has been successfully opened during PCI -- the amount of tissue damaged by the heart attack tends to be greater, recovery of heart function reduced, and the risk of death higher.
