"Cardiac catheterization &amp;amp;#150; an invasive diagnostic procedure that allows doctors to see the vessels and arteries leading to the heart and its chambers &amp;amp;#150; is performed thousands of times in the United States each year and, in some cases, can be the best method to diagnose heart problems. Still, the procedure is costly and may pose risks to certain patients, so determining when the benefits of performing the procedure outweigh the risks is essential. A new report issued today by the American College of Cardiology Foundation (ACCF) and the Society for Cardiovascular Angiography and Interventions (SCAI) in collaboration with a dozen other professional societies provides detailed criteria to help clinicians determine when cardiac catheterization is a reasonable option for the evaluation of patients for heart disease."^^<http://www.w3.org/2001/XMLSchema#string>
