Ultrasound is frequently used for guidance of minimally invasive cardiovascular interventions, such as cardiac ablations and structural heart interventions. Intracardiac echocardiography (ICE) has the ability to provide high resolution images from within the heart, but has primarily been limited to 2D ultrasound imaging.
We developed a 10F ICE catheter and system received FDA 510k clearance and is capable of generating 2D side-viewing cross-sectional images and 3D volume renderings as well as 2D color doppler. The transducer rotates 360 degrees within the catheter and can tilt from a side viewing orientation to a forward viewing orientation to sweep through a 3D forward-looking volume. Pre-clinical images were collected under a local Animal Care Committee approved protocol in porcine models. Clinical images were acquired under an REB-approved protocol and a Health Canada Investigational Testing Authorization.
Pre-clinical and clinical images of the IVC, SVC, all four cardiac chambers, valves, fossa ovalis, pulmonary veins, left atrial appendage (LAA), atrial septum, coronary sinus and devices have been collected. The left figure panel is a 2D cross-sectional clinical image of the left atrium (LA), right atrium (RA) and septal tenting. The middle panel is one of several 2D images used to generate a 3D image (Figure 1C) of left-sided structures within one second, including the left atrial appendage (LAA) and left superior pulmonary vein (LSPV).
Imaging with this new rotational ICE platform is feasible and may create new options for guidance of minimally invasive procedures.
