Summary
Pericardial valves are typically used in older patients to avoid anticoagulation and calcification. However, this case shows early calcification in a Sorin pericardial aortic valve.
Area of Science:
- Cardiovascular surgery
- Biomaterials science
- Medical device engineering
Background:
- Pericardial valves are frequently chosen for older patients due to reduced anticoagulation needs.
- These bioprosthetic valves are generally considered less prone to calcification in elderly recipients compared to younger ones.
Observation:
- A case of premature calcification was observed in a Sorin pericardial valve.
- The affected valve was implanted in the aortic position.
Findings:
- Early and significant calcification occurred in the pericardial valve.
- This finding challenges the established understanding of bioprosthetic valve durability in specific patient demographics.
Implications:
- This case highlights the potential for early bioprosthetic valve failure due to calcification, even in older patients.
- Further research is needed to understand the mechanisms and risk factors for early calcification in pericardial valves.
- Clinical surveillance protocols may need to be re-evaluated for patients receiving pericardial valves.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
