Novel Management for Stuck Mechanical Aortic Valve Leaflet Following Bentall With Bovine Aortic Arch.

ABSTRACT:

Background

Mechanical heart valves offer long-term durability but carry a risk of thrombosis, even with therapeutic anticoagulation.

Case summary

We present a case of a patient with a history of Bentall procedure and bovine aortic arch who developed a thrombotic stuck mechanical aortic valve. Despite therapeutic international normalized ratio and administration of thrombolytics, the obstruction persisted. Given the patient's high surgical risk, a novel percutaneous interventional approach was used, resulting in restoration of valve function and a favorable clinical outcome.

Discussion

Mechanical valve thrombosis is a rare but life-threatening condition with an incidence of 0.1% to 5.7%. Although subtherapeutic international normalized ratio is a common cause, cases ma
