Myocardial fibrosis in congenital heart disease

Area of Science:

• Cardiovascular Pathology
• Cardiac Physiology

Background:

• Myocardial fibrosis, characterized by excessive collagen deposition, is a key feature in various cardiovascular diseases, including congenital heart anomalies.
• Interstitial fibrosis significantly contributes to myocardial dysfunction by disrupting cardiac architecture and altering interstitial properties.

Purpose of the Study:

• To review the mechanisms and consequences of myocardial fibrosis in heart failure and arrhythmias.
• To evaluate current imaging and biomarker strategies for assessing myocardial fibrosis.
• To synthesize evidence on myocardial fibrosis in congenital heart diseases for research and treatment implications.

Main Methods:

• Literature review of existing research on myocardial fibrosis.
• Analysis of studies focusing on mechanisms, consequences, and assessment methods.
• Synthesis of data related to myocardial fibrosis in congenital heart disease subsets.

Main Results:

• Myocardial fibrosis is a significant contributor to myocardial dysfunction and adverse cardiac remodeling.
• Current imaging techniques and biomarkers show promise but require further validation for fibrosis assessment.
• Evidence highlights the presence and impact of myocardial fibrosis across diverse congenital heart disease types.

Conclusions:

• Understanding myocardial fibrosis mechanisms and consequences is crucial for managing cardiovascular diseases.
• Improved diagnostic tools are needed for accurate myocardial fibrosis detection and quantification.
• Targeting myocardial fibrosis presents a potential therapeutic strategy for improving outcomes in congenital heart disease.
