In brief: Depends
Depends on what is being done.
For a simple left heart diagnostic cath, about 20 minutes. If it's a left and right heart diagnostic cath, about 40 minutes. If an angioplasty and stent are also placed, about 60-90 minutes. If there are technical problems, it can sometimes take longer.

In brief: Depends
The procedure itself, if just a diagnostic coronary angiogram, may be over within a half hour, but if there are interventions, or valvular or congenital abnormalities in question, other additional procedures may be part of the catheterization procedure adding perhaps another hour. The time in the lab itself is longer because of the prep time and post-test assessment and ensuring no complications.
