Heart Valves

Heart Valves

The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Background:

Valvular heart disease is a major global health concern.
Transcatheter heart valve replacement offers minimally invasive options but uses bioprostheses prone to degeneration.
Tissue engineering presents a potential solution for durable, living heart valves.

Purpose of the Study:

To provide an overview of transcatheter tissue engineered heart valves (tTEHVs).
To explore the integration of minimally invasive techniques with living valve generation.
To summarize current preclinical data on tTEHVs.

Main Methods:

Review of existing literature on transcatheter techniques and tissue engineering for heart valves.
Analysis of preclinical data regarding the development and testing of tTEHVs.
Conceptualization of a combined approach for valve generation and implantation.

Main Results:

Transcatheter techniques enable minimally invasive delivery of engineered heart valves.
Tissue engineering offers the potential for autologous, living valves that may resist degeneration.
Preclinical studies show promise for tTEHV concepts.

Conclusions:

Transcatheter tissue engineered heart valves represent a promising future therapy for valvular heart disease.
This approach merges minimally invasive implantation with living, autologous valve creation.
Further preclinical development is essential to advance tTEHVs towards clinical application.
