Abstract
Intracardiac echocardiography (ICE) provides real-time ultrasound imaging of the heart anatomy from inside, guiding interventions like valve repair, closure of atrial septal defects (ASD) and catheter-based ablation to treat atrial fibrillation. With its better image quality and ease of use, ICE is becoming the preferred imaging modality over transesophageal echography (TEE) for structural heart interventions. The existing commercial ICE catheters, however, offer a limited 2-D or 3-D field of view despite catheters utilizing large number of wires. In these catheters, each element in the ICE array is connected to the backend data-acquisition channel with a separate wire, which is a critical barrier for improving image quality and widening the field of view. In order to use ICE catheters under MRI instead of the ionizing X-ray radiation-based angiography, the number of interconnect wires in the catheter should be minimized to reduce RF-induced heating. Furthermore, reducing the number of wires improves the flexibility and lowers the cost of the single-use ICE catheters.
