What is cardiac catheterization used for?

Cardiac catheterization is primarily used to evaluate heart conditions by providing detailed information about the structure and function of the heart. During the procedure, a thin, flexible tube called a catheter is inserted into a blood vessel and guided to the heart. This allows for various diagnostic tests, such as imaging the coronary arteries to identify blockages, assessing the heart chambers, and measuring pressures within the heart. The data gathered during catheterization can help healthcare providers make informed decisions regarding treatment for various cardiac issues.

The other choices describe functions that are either not solely the purpose of cardiac catheterization or are misrepresentations of its capabilities. While cardiac catheterization may help in diagnosis and inform treatment for valve issues or damage, it does not permanently correct heart valve issues or heal damaged tissue itself. It also goes beyond simply measuring blood pressure, as it provides a comprehensive evaluation of heart health.
