This study, called REBIRTH, is looking at two ways to do a heart procedure called cardiac catheterization. This procedure helps doctors see inside the heart and blood vessels. The study compares two methods for accessing the heart: radial access (using an arm artery) and state-of-the-art femoral access (using a leg artery). People who join will be randomly placed in one of these two groups, like flipping a coin. Doctors are trying to find out which method causes less bleeding and fewer problems.

Key Points:

• The study involves random assignment to one of two groups: radial or femoral access.
• Only adults who qualify, and do not have certain health conditions, can join the study.
• If you join, you must agree to the procedure and several follow-up visits.

Participants need to be at least 18 years old and agree to be part of the study. They should not have certain heart conditions or be pregnant. This study is not for people who need urgent heart procedures right away. Joining the study means you will help doctors learn more about the safest ways to perform heart procedures.
