Aortic wrapping and personalised external aortic root support (PEARS) prevent aortic expansion. CT scans show gaps in wrapping, unlike PEARS, which offers a tighter fit for better aortic dissection prevention.
Area of Science:
- Cardiovascular Surgery
- Medical Imaging
- Biomaterials
Background:
- Ascending aortic expansion increases risks of dissection and rupture.
- Aortic wrapping and PEARS are surgical techniques to reinforce the aorta.
- CT imaging is crucial for evaluating these aortic interventions.
Discussion:
- Plonek et al. systematically report CT findings of aortic wrapping.
- Residual spaces between the aorta and wrap are observed in wrapping cases.
- Personalised External Aortic Root Support (PEARS) demonstrates intimate contact with the aorta due to its custom design and porous mesh.
Key Insights:
- CT imaging reveals gaps between the aorta and the wrapping material.
- PEARS achieves superior aortic apposition compared to wrapping.
- Wrapping offers intraoperative flexibility, usable in emergencies, unlike elective PEARS.
Outlook:
- Further research into optimizing aortic wrapping techniques to minimize gaps.
- Investigating the long-term efficacy and integration of PEARS.
- Comparing clinical outcomes and patient benefits of both aortic interventions.

Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
