Yes, if necessary, more than one cardiac catheterization can be done in one week. More than one in one or two days may be dangerous, however, because the dye used during the test can cause kidney damage in susceptible people.

Some examples of why more than one cardiac catheterizations may need to be performed could be re-occlusion of an angioplastied or stented vessel, vessel aneurysm or dissection, or another myocardial infarction within that time period.
