Automated assessment of the aortic root dimensions with multidetector row computed tomography

Area of Science:

• Cardiology
• Radiology
• Medical Imaging

Background:

• Accurate aortic root measurements are vital for transcatheter aortic valve implantation (TAVI) preoperative planning.
• Standardization of measurements can improve procedural success and reduce complications.
• Evaluating novel automated software for aortic root assessment in TAVI candidates is necessary.

Purpose of the Study:

• To evaluate the accuracy and reproducibility of the 3mensio Valves software for aortic root assessment in TAVI candidates.
• To compare automated measurements with manual measurements using multidetector row computed tomography (MDCT).

Main Methods:

• Ninety patients with aortic valve disease underwent 64-row and 320-row MDCT.
• Aortic valve annular size, aortic root dimensions, and coronary ostia height were measured using 3mensio Valves software.
• Measurements were compared to manual assessments using Vitrea2 software.

Main Results:

• Automated assessment of aortic valve annulus and root dimensions was feasible in all patients.
• Excellent agreement (ICC 0.97-0.99) and minimal bias were found between automated and manual MDCT measurements.
• The automated software demonstrated superior interobserver reproducibility and reduced postprocessing time.

Conclusions:

• The 3mensio Valves software enables reliable, reproducible, and automated assessment of aortic root dimensions and spatial relationships.
• This automated tool has significant clinical implications for preoperative TAVI assessments.
• Automated MDCT postprocessing software enhances the accuracy and efficiency of TAVI planning.
