Background:

Congenital heart defects often require complex surgical interventions.
Repair or replacement of atrioventricular valves in infants presents significant challenges.
Decellularized extracellular matrix (ECM) is a promising biomaterial for tissue engineering.

Observation:

A handmade left atrioventricular valve using decellularized ECM was previously feasible for 3 months.
This study reports the successful 9-month use of an ECM mitral valve in an infant with an unrepairable congenital valve malformation.
The ECM valve functioned effectively without the need for anticoagulation.

Findings:

The ECM mitral valve demonstrated excellent short-term durability and function in a pediatric patient.
The patient expired due to non-cardiac complications related to a fibrillin gene defect, not valve failure.
This case expands the application of ECM valves to the systemic ventricle.

Implications:

Decellularized ECM holds potential for creating functional, durable cardiac valves for pediatric patients.
Further research into ECM valve technology could lead to improved treatments for congenital heart disease.
The use of ECM valves may reduce the need for long-term anticoagulation in certain patient populations.
