Insights
External aortic clamping poses risks for patients with atherosclerosis. The Heartport Endoaortic Clamp offers a novel solution for cardiac arrest management during surgery in these high-risk individuals.
Area of Science:
- Cardiovascular Surgery
- Medical Device Technology
Background:
- External aortic clamping in atherosclerotic ascending aorta surgery increases risks of embolic events and aortic injury.
- Limited management options exist for cardiac arrest during operations in these patients.
Observation:
- The Heartport Endoaortic Clamp (Heartport, Redwood City, CA) was utilized as an alternative approach.
Findings:
- The Heartport Endoaortic Clamp provides a potential solution for managing cardiac arrest in patients with atherosclerotic ascending aortas.
Implications:
- This approach may reduce embolic and traumatic risks associated with traditional clamping.
- Further research is warranted to validate the safety and efficacy of the Endoaortic Clamp in this patient population.
Abstract:
Application of an external cross-clamp to an atherosclerotic ascending aorta increases the risk of an embolic event and traumatic injury of the aorta. Currently, there are limited management options in these patients when the clinical situation requires cardiac arrest during an operation. We present our approach to these patients using the Heartport Endoaortic Clamp (Heartport, Redwood City, CA).
