Summary
Background:
- Currently, heart catheterization procedures are guided by X-rays. Researchers are
developing new techniques to perform heart catheterization without the use of X-rays by
investigating possible uses of magnetic resonance imaging (MRI) scans. To study these uses,
researchers are interested in performing a part of the standard X-ray catheterization
procedure using MRI on individuals who are scheduled to have heart catheterization.
Objectives:
- To examine the safety and feasibility of right-heart catheterization using MRI-guided
catheters.
Eligibility:
- Individuals at least 21 years of age who are undergoing a medically necessary heart
catheterization procedure.
Design:
- The research MRI procedure will be performed either before or after standard X-ray
guided heart catheterization.
- Participants will be transferred from an X-ray table onto an MRI table and advanced
into the scanner. Under MRI guidance, a MRI-compatible catheter will be used to measure
blood pressure and blood oxygen levels in the heart, and MRI scanning will be performed
for approximately 30 minutes.
