Summary
Tilting disc valve thrombosis is a serious complication occurring years after mitral or aortic valve replacement. Prompt recognition of symptoms and diligent anticoagulation are crucial to prevent fatal outcomes.
Area of Science:
- Cardiovascular Surgery
- Biomaterials Science
- Clinical Medicine
Context:
- Mechanical heart valves, specifically tilting disc valves (Björk-Shiley and Lillehei-Kaster), are used for valve replacement.
- Valve thrombosis is a known complication following mechanical heart valve implantation.
Purpose:
- To report on the incidence and outcomes of valve thrombosis in patients with tilting disc heart valves.
- To emphasize the importance of anticoagulation and timely surgical intervention for suspected valve thrombosis.
Summary:
- Nine patients (7 female, 2 male, average age 46) developed valve thrombosis 0.5-5.5 years post-mitral (n=6) or aortic (n=3) valve replacement.
- Reoperation was required in eight cases, often as an emergency, with a high mortality rate (6/9 patients died).
- Key symptoms include loss of valve click and cardiac insufficiency, particularly with irregular anticoagulation.
Impact:
- Highlights the significant risk of late valve thrombosis with specific mechanical valve designs.
- Underscores the critical role of strict anticoagulation management in preventing thrombotic events.
- Stresses the need for immediate cardiac surgical consultation upon suspicion of valve thrombosis to improve patient survival.
