Insights
Calcific aortic valve disease (CAVD) lacks medical treatments. Understanding CAVD
Area of Science:
- Cardiovascular Biology
- Pathology
- Molecular Medicine
Background:
- Calcific aortic valve disease (CAVD) is the most prevalent heart valve disorder.
- Currently, no medical interventions exist to prevent or reverse CAVD progression.
- A deeper understanding of CAVD's underlying mechanisms is crucial for therapeutic development.
Purpose of the Study:
- To review the molecular mechanisms driving fibrosis and mineralization in CAVD.
- To explore the roles of lipid retention, inflammation, phosphate signaling, and osteogenic transition in CAVD pathogenesis.
- To discuss the interplay between these processes and their clinical relevance.
Main Methods:
- Literature review focusing on molecular and cellular processes in CAVD.
- Analysis of recent advancements in understanding CAVD pathobiology.
- Synthesis of information on key regulatory pathways involved in valve disease.
Main Results:
- Lipid retention, inflammation, phosphate signaling, and osteogenic transition are key molecular drivers of CAVD.
- Complex interplays exist between these processes, influencing disease progression.
- Understanding these pathways offers potential targets for novel pharmaceutical therapies.
Conclusions:
- Elucidating the molecular underpinnings of CAVD, including fibrosis and mineralization, is essential.
- Targeting lipid retention, inflammation, phosphate signaling, and osteogenic transition may lead to new treatments for CAVD.
- Further research into these pathways holds promise for developing effective pharmaceutical interventions.
Abstract:
Calcific aortic valve disease (CAVD) is the most common heart valve disorder. There is no medical treatment to prevent and/or promote the regression of CAVD. Hence, it is of foremost importance to delineate and understand the key basic underlying mechanisms involved in CAVD. In the past decade our comprehension of the underpinning processes leading to CAVD has expanded at a fast pace. Hence, our understanding of the basic pathobiological processes implicated in CAVD might lead eventually to the development of novel pharmaceutical therapies for CAVD. In this review, we discuss molecular processes that are implicated in fibrosis and mineralization of the aortic valve. Specifically, we address the role of lipid retention, inflammation, phosphate signalling and osteogenic transition in the development of CAVD. Interplays between these different processes and the key regulation pathways are discussed along with their clinical relevance.
