Summary
The Valiant Navion stent graft system shows promising safety and efficacy for thoracic endovascular aortic repair in Asian patients. This study highlights its versatility in treating various aortic pathologies with high technical success rates.
Area of Science:
- Cardiovascular Surgery
- Medical Devices
- Endovascular Therapy
Background:
- The Valiant Navion stent graft system is a third-generation endograft for thoracic endovascular aortic repair (TEVAR).
- This study presents the initial Asian experience with this device in an all-comers population.
Purpose of the Study:
- To evaluate the safety and efficacy of the Valiant Navion stent graft system in Asian patients undergoing TEVAR.
- To report on the outcomes of TEVAR using this new stent graft in a diverse group of patients with various aortic pathologies.
Main Methods:
- A prospective recruitment and retrospective analysis of 21 patients undergoing TEVAR between May 2019 and October 2020.
- Evaluation of clinical and device-related outcomes, including survival, technical success, complications, endoleaks, and hospital stay.
Main Results:
- The most common indications were penetrating aortic ulcers and aortic transection/rupture.
- 100% deployment accuracy and 94.7% technical success rate were achieved.
- No major vascular or neurological complications were observed; 30-day survival was complete.
Conclusions:
- The Valiant Navion stent graft system demonstrated versatility, safety, and efficacy in this Asian cohort.
- This case series supports the use of the Valiant Navion stent graft for TEVAR in Asian patients with diverse aortic conditions.
