Purpose: The objective of this study is to validate a novel workflow for implementing patient-specific finite element (FE) simulations to virtually replicate the Transcatheter Aortic Valve Implantation (TAVI) procedure.
Methods: Seven patients undergoing TAVI were enrolled. Patient-specific anatomical models were reconstructed from pre-operative computed tomography (CT) scans and subsequentially discretized, considering the native aortic leaflets and calcifications.
Objective: The objective of this study is to investigate and address the question surrounding the determination of the optimal endograft length of coverage during TEVAR for type B aortic dissection (TBAD), with a particular emphasis on the distal landing zone (DLZ).
Data Sources: MEDLINE, Scopus, and Web of Science databases were used.
Methods: The PRISMA-ScR statement was followed.
Article Synopsis
- TAVI and TEVAR are quick and less invasive surgeries to fix aortic valve problems and aorta diseases.
- Researchers found that including aortic pre-stress in simulations helps predict how devices will work better than ignoring it.
- Ignoring aortic pre-stress can lead to big mistakes, like underestimating stress and pressure on the heart, so it's important to include it in practice.
Utilizing numerical simulations to prevent stent graft kinking during thoracic endovascular aortic repair.
J Vasc Surg Cases Innov Tech
September 2023
Numerical simulations of thoracic endovascular aortic repair (TEVAR) may be implemented in the preoperative workflow if credible and reliable. We present the application of a TEVAR simulation methodology to an 82-year-old woman with a penetrating atherosclerotic ulcer in the left hemiarch, that underwent a left common carotid artery to left subclavian artery bypass and consequent TEVAR in zone 2. During the intervention, kinking of the distal thoracic stent graft occurred and the simulation was able to reproduce this event.
