Phantom study of an ultrasound guidance system for transcatheter aortic valve implantation
A guidance system for TAVI using ultrasound and magnetic tacking was developed. Eliminates the use of nephrotoxic contrast and ionizing radiation. In phantom experiment, similar accuracy in deployment depth as with fluoroscopy. A new delivery tool with integrated ICE further improves deployment accuracy.
