Study Overview
Brief Summary
The INTELICE trial is a prospective, multicenter, 1:1 randomized controlled non-inferiority study. It aims to compare a novel intracardiac echography (ICE) catheter and combined ultrasound system with existing commercial ones. The evaluation will be conducted on patients undergoing planned intracardiac interventional process.
Detailed Description
This randomized controlled trial will enroll adult patients undergoing cardiac interventions, who will be randomly assigned to either the experimental device group or the control group.
The main endpoint of the INTELICE trial is the image quality rate of intracardiac echocardiography, which will be evaluated by three experienced sonographers from the core laboratory, while the operator's image quality assessment serves as a secondary endpoint. In addition, secondary endpoints include clinical success rate, technical success rate, procedure time, and evaluation for the experimental devices.

- •Other exclusive circumstances determined by the investigators, where the subject is deemed unsuitable for enrollment.
Outcomes
Primary Outcomes
Image quality
Time Frame: Up to 6 months
The image quality will be assessed by three cardiac sonographers. Sonographers will score based on image parameters such as image clarity, penetration, temporal and spatial resolution, blood flow, etc. The evaluation with utilize a 1-5 scale scoring system. A score of 5 indicates that the images are excellent and suitable for clinical needs, while a score of 4 suggests good quality. 3 indicates that the image has flaws but still meets the clinical needs. Scores of 1 and 2 signify poor or bad image quality, which can affect clinical diagnosis and treatment.
Secondary Outcomes
- Procedure time(Up to 24 hours)
- Technical success(Up to 24 hours)
- Image quality(Up to 48 hours)
- Procedure success(Up to 24 hours)
