MRI Fluoroscopy in Heart Catheterization with Passive Guidewires

This study investigates a new way to perform heart catheterization using MRI fluoroscopy instead of traditional X-ray guidance. Heart catheterization helps doctors measure the pressure inside the heart, but using X-rays can expose patients to radiation and doesn't show soft tissues clearly. This research is particularly important for people with heart issues because it explores a safer method that reduces radiation exposure while still providing detailed images. The study focuses on using special guidewires that won’t heat up during MRI, making it possible to perform the procedure safely. Participants in this study will undergo heart catheterization using MRI technology, where guidewires will help steer the catheters through the veins and arteries of the heart. The process involves using low-energy MRI techniques to guide the catheters without the need for X-rays. The study will evaluate how well this technique works by measuring heart function and responses during the procedure. By testing the safety and effectiveness of this method, researchers aim to refine the technique, which could eventually lead to new treatments for heart conditions without surgery.
