MRI-Guided Technique for Cardiac Ablation

The study, reported in the August issue of Circulation, was conducted by a team of researchers from the departments of radiology and cardiology at the Johns Hopkins University School of Medicine (JHU, Baltimore, MD, USA).

The new technique utilizes a miniature internal coil developed by Surgi-Vision (Columbia, MD, USA) and cleared by the U.S. Food and Drug Administration (FDA) last year. The benefits of using MRI instead of x-rays, says Surgi-Vision, are the elimination of ionizing radiation exposure, greater accuracy in therapy titration, and the facilitation of the creation of linear, contiguous, and transmural lesions.

"This approach represents a shift away from x-ray guided techniques and establishes the feasibility of performing cardiovascular intervention under MRI guidance,” said lead author Albert C. Lardo, Ph.D.

Surgi-Vision is an emerging medical device company formed to manufacture and market specialized imaging products based on research conducted at JHU. The company is developing a range of devices for the MRI-guided diagnosis and treatment of various disorders.
