XFM: (X-ray Fused With MRI) Guided Cardiac Catheterization

This study will evaluate the use of x-ray fused with MR images as an imaging tool to help guide catheter tools during diagnostic and therapeutic cardiac catheterization procedures.

Cardiovascular interventional procedures are currently conducted under the guidance of X-ray fluoroscopy. Magnetic resonance imaging (MRI) can provide increased soft tissue information about the cardiovascular system. By combining the familiar X-ray environment with superior magnetic resonance imaging, the investigator hopes to enhance and expand the capabilities of cardiac catheterization techniques. The investigator will conduct cardiac catheterization procedures using XFM guidance in pediatric research patients who are undergoing medically necessary procedures. The investigator aims to decrease the exposure of these patients to the routine hazards of ionizing radiation and contrast exposure compared to the standard of care approach.

X-ray images and MRI roadmaps are aligned, during the medically indicated catheterization procedure, both conventional X-ray and investigational XFM images are displayed side-by-side. The operator may choose to be guided by either.
