Magnetic navigation in percutaneous coronary and non-coronary interventions

There is no question that Percutaneous Coronary Intervention has revolutionized the way we manage coronary artery disease. Over the past two decades we have witnessed maturity in several techniques and equipment enabling the interventional cardiologist to manage lesions that have previously been entirely in the domain of the cardiac surgeon. Despite these remarkable achievements there still remain lesions that are complex enough to create a challenge in the most experienced hands.The inherent tortuosity in complex vascular anatomies, branching segments and chronically occluded vessel have been all associated with lower procedural success and higher complication rates when compared to the “straight forward vessels”. The Magnetic Navigation System (MNS) is a novel and versatile technology that allows the re-orientation of a wire within the patient’s body. This unique ability means that the “trial and error” method of externally re-shaping the tip of the wire and re-engaging the vessel can be effectively eliminated. As such previously “unreachable areas” in the heart or within the vascul
