Abstract
<p style="text-align:justify"><span style="font-size:medium"><span style="font-family:"Times New Roman",serif"><span style="color:#000000"><strong><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Introduction:</span></span></strong><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"> TAVI planning with dedicated CT software is a key component of any TAVI program. The Pie Medical 3mensio software suite is the most commonly used system. Some competitors are also available. However, all this software is limited by very significant costs, both upfront and regarding updates. As a result, open source or more affordable software would be ideal in order to reduce the costs of TAVI and increasing availability. We aimed to develop an open-source software plugin for TAVI sizing, comparing its results with the gold standard, 3mensio. </span></span></span></span></span><span style="font-size:medium"><span style="font-family:"Times New Roman",serif"><span style="color:#000000"><strong><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Methods:</span></span></strong><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"> A python plugin for the open-source software 3D Slicer was written by an Interventional Cardiologist with python coding knowledge, aided by artificial intelligence coding assistants. The software requires the input of the 3 cusps nadir and marking reference points of the aortic ring, similarly to the 3mensio software. From there, the fluoroscopic angles and ring measurements are made automatically (figure 1). 50 consecutive successful TAVI cases were selected. Measurements had been carried out by Interventional Cardiologists proficient in TAVI using the 3mensio software. Measurements were then carried out in the 3D slicer plugin. The results of the aortic annulus measurements were then compared between the two software methods (perimeter, area, area derived diameter, mean diameter, maximum diameter, minimum diameter), using the t-test for assessing differences. </span></span></span></span></span><span style="font-size:medium"><span style="font-family:"Times New Roman",serif"><span style="color:#000000"><strong><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Results: </span></span></strong><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">A total of 50 measurements carried out with 3mensio software revealed a mean minimum diameter of 21.1 </span></span><span style="font-size:11pt"><span style="font-family:Symbol">±</span></span><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">2.68 mm; mean maximum diameter of 26.465 </span></span><span style="font-size:11pt"><span style="font-family:Symbol">±</span></span><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"> 2.92 mm, mean perimeter of 75.26 </span></span><span style="font-size:11pt"><span style="font-family:Symbol">±</span></span><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"> 8.62mm and mean area of 442.07 </span></span><span style="font-size:11pt"><span style="font-family:Symbol">±</span></span><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"> 99.63 mm<sup>2</sup>.

The comparison of the two measurements revealed that only the perimeter was significantly different between the 2 tools (p value <0.001), with an absolute mean difference of 1.21 mm. </span></span></span></span></span><span style="font-size:medium"><span style="font-family:"Times New Roman",serif"><span style="color:#000000"><strong><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Conclusions: </span></span></strong><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><span style="color:black">Our plugin produced measurements for aortic annulus dimensions that were highly comparable to those generated by the gold standard Trimensio software, with no significant differences observed for most parameters. The only exception was the perimeter, which showed a statistically significant but small absolute difference of 1.21 mm. Despite being statistically significative, this difference is probably not clinically relevant. The open-source plugin may offer a viable alternative for TAVI sizing, potentially reducing software-related costs and increasing accessibility to TAVI programs. </span></span></span></span></span></span></p>
