Aortic dissection after sutureless valve and chest compressions.

Area of Science:

• Cardiovascular Surgery
• Medical Device Complications
• Aortic Pathology

Background:

• Sutureless aortic valves, like the Perceval valve, offer procedural advantages and good long-term outcomes.
• Potential aortic complications linked to the self-expanding stent structure require further understanding.

Purpose of the Study:

• To report a case of early-onset localized ascending aortic dissection following sutureless aortic valve replacement.
• To investigate the potential mechanism of stent-aortic wall interaction causing dissection.

Main Methods:

• Case report of an 85-year-old female patient.
• Analysis of the location and extent of aortic dissection relative to the sutureless valve stent and aortotomy.

Main Results:

• The patient developed localized ascending aortic dissection shortly after aortic valve replacement with a sutureless valve.
• The dissection entry tear was identified at the stent edge, near the aortotomy suture line.
• The dissection was confined between the stent edge and the aortotomy.

Conclusions:

• Sutureless aortic valves may be associated with localized aortic dissection.
• External mechanical stress from stent-aortic wall interaction could trigger dissection.
• Further research is needed to fully understand and mitigate these risks.
