The field of interventional cardiology has developed at an unprecedented pace on account of the visual and imaging power provided by constantly improving biomedical technologies. Transcatheter-based technology is now routinely used for coronary revascularization and noncoronary interventions using balloon angioplasty, stents, and many other devices. In the early days of interventional practice, the operating physician had to manually navigate catheters and devices under fluoroscopic imaging and was exposed to radiation, with its comcomitant necessity for wearing heavy lead aprons for protection. Until recently, very little has changed in the way procedures have been carried out in the catheterization laboratory. The technological capacity to remotely manipulate devices, using robotic arms and computational tools, has been developed for surgery and other medical procedures. This has brought to practice the powerful combination of the abilities afforded by imaging, navigational tools, and remote control manipulation. This review covers recent developments in navigational tools for catheter positioning, electromagnetic mapping, magnetic resonance imaging (MRI)-based cardiac electrophysiological interventions, and navigation tools through coronary arteries.
