Summary
Artificial intelligence (AI) automated planning for transcatheter aortic valve replacement (TAVR) using Mimics for TAVR is accurate and efficient. This AI tool significantly reduces planning time compared to semi-automated methods.
Area of Science:
- Cardiology
- Medical Imaging
- Artificial Intelligence
Background:
- Preprocedural planning using multislice computed tomography (MSCT) is crucial for transcatheter aortic valve replacement (TAVR).
- Current planning methods are time-consuming and prone to interobserver variability.
- AI-driven automated planning offers a potential solution to improve efficiency and accuracy.
Purpose of the Study:
- To validate the clinical accuracy and efficiency of the AI-driven Mimics for TAVR planning tool.
- To compare Mimics for TAVR with existing semi-automated planning software.
- To assess the agreement of anatomical measurements derived from the AI tool.
Main Methods:
- Key pre-TAVR MSCT datasets from 126 patients were analyzed using Mimics for TAVR and a semi-automated software.
- Agreement between the two methods was evaluated using intraclass correlation coefficients (ICCs) and Bland-Altman plots.
- Planning time for each method was recorded and compared.
Main Results:
- Mimics for TAVR demonstrated high accuracy and excellent agreement for aortic annulus area (ICC: 0.976), left ventricular outflow (ICC: 0.970), and other key anatomical measurements.
- The AI tool significantly reduced analysis time per case (1.03 min vs. 9.55 min, p=0.001).
- Measurements included sinotubular junction, coronary heights, and membranous septum length with high ICCs.
Conclusions:
- The AI-driven Mimics for TAVR planner is an accurate and reliable alternative to current semi-automated TAVR planning platforms.
- This automated tool can significantly enhance overall workflow efficiency in TAVR procedures.
- Mimics for TAVR provides precise anatomical measurements, potentially improving TAVR outcomes.
