• To identify novel technologies and remaining challenges for clinical translation.

Main Methods:

• Review of existing literature on whole heart bioengineering techniques.
• Analysis of decellularization, cell sourcing, repopulation strategies, and maturation processes.
• Discussion of scaling-up strategies from small to human-sized organs.

Main Results:

• Significant progress has been made in whole heart bioengineering, moving closer to clinical application.
• Key stages involve successful decellularization, effective cell repopulation, and organ maturation.
• Novel technologies are emerging, but challenges remain for full clinical translation.

Conclusions:

• Whole heart bioengineering is a promising frontier for treating cardiac failure.
• Further advancements in technology and overcoming current hurdles are necessary for clinical success.
• The field is evolving rapidly, with potential for future life-saving therapies.
