Study Notes
Aortic Stenosis due to Calcification of the Aortic Valve
- Calcification of the aortic valve is caused by dystrophic calcification, which is the deposition of calcium following cellular injury.
- Cellular injury can result in calcium deposition in heart valves, leading to conditions such as aortic stenosis.
- This type of calcification is distinct from metastatic calcification, which is associated with increased serum calcium levels and can be caused by factors such as Paget disease, cancer with metastases, or excess vitamin D.
- Metastatic calcification can also be caused by phosphate retention, leading to calcium deposits.
- In the context of aortic stenosis, dystrophic calcification is the primary mechanism of calcification, rather than metastatic calcification.
Test your knowledge on a 68-year-old male client with aortic stenosis secondary to calcification of the aortic valve. Identify key aspects of the client's condition and potential contributing factors.
