[SEMİNER] Interventional Heart Catheterization under MRI: Is it possible or just a dream?

Tarih: 16.12.2011
Yer: Kandilli

Minimally invasive and catheter‐based therapies are targeting increasingly complex pathologies recently. This agenda requires better procedural image guidance. Real‐time MRI‐guided cardiovascular intervention proposes to use the superb tissue imaging afforded by MRI as a surrogate for direct surgical visualization. By providing multiple views and real‐time functional imaging without ionizing radiation exposure, MRI could guide traditional interventional procedures and enable novel ones especially for  children who are sensitive to long‐term toxicity from radiation exposure. There are limited availability of catheter devices that are safe and visible under MRI. Almost all X‐ray guidewires either are invisible or unacceptable for use during real‐time MRI procedures. Metallic guidewire cores cause imaging artifacts and obscure entire organs.Polymer‐only guidewires are not visible unless modified and often lack requisite mechanical performance. There are no commercially available “active” MRI guidewires incorporate electronics exploited by the MRI system itself to enhance visibility, which is why we have designed and developed one at NHLBI. This presentation summarizes basic medical device design principles that were applied during the clinical grade active guidewire development for heart catheterization under MRI.
