Evaluation of cell death markers in severe calcified aortic valves.
Degenerative aortic valve disease is the most frequent acquired valve disease. Especially in the elderly, its prevalence is increasing. Once the disease becomes symptomatic, it is rapidly fatal. The disease cannot be considered a result of aging alone. The condition is an active process, which occurs with rapid progression, especially when calcification can be documented. This calcification can be the end result of cellular mechanisms involving cell death pathways (such as autophagy) and cellular matrix remodeling. These processes are beginning to be unraveled in the initiation and propagation of the disease. Autophagy could be the common step through which these mechanisms lead to this pathway of cell death in this disease. Autophagy can be detected by procedures described hereafter.
