Summary
Isolated perfused heart models offer reproducible methods for studying cardiovascular diseases (CVDs) and testing therapies. Ex vivo heart perfusion (EVHP) also enhances donor heart preservation for transplantation.
Area of Science:
- Cardiovascular Research
- Physiology
- Transplantation Biology
Background:
- Isolated perfused hearts, used since the 19th century, are valuable tools for studying cardiovascular diseases (CVDs).
- These models are crucial for investigating cardiac function, metabolism, and electrophysiology.
- They are also used for testing novel therapeutic strategies and modeling various CVDs.
Approach:
- This review traces the historical development of isolated perfused heart techniques.
- It highlights their diverse applications in understanding cardiac mechanisms.
- The review also discusses the emerging role of ex vivo heart perfusion (EVHP) in cardiac transplantation.
Key Points:
- Isolated perfused hearts provide cost-effective and reproducible experimental models.
- Applications include therapy testing, metabolic and electrophysiological studies, and CVD modeling (e.g., ischemic heart disease, arrhythmias).
- Ex vivo heart perfusion (EVHP) shows promise for extending donor heart viability and reconditioning.
Conclusions:
- Isolated heart models are versatile tools in cardiovascular research.
- Understanding their capabilities aids in investigating complex CVD mechanisms.
- EVHP represents a significant advancement in cardiac preservation and transplantation strategies.
