Total Artificial Heart vs Left Ventricular Assist Device and Biventricular Assist Device.

Area of Science:

• Cardiology and Mechanical Circulatory Support
• Heart Transplantation and Artificial Organs

Background:

• Biventricular heart failure presents significant challenges in end-stage cardiomyopathy patients.
• Right ventricular failure is a major complication of durable left ventricular assist devices (LVADs), impacting patient outcomes.
• Evolving heart transplant allocation systems influence the use of mechanical circulatory support.

Purpose of the Study:

• To review current practice patterns in mechanical circulatory support for biventricular failure.
• To discuss strategies for bridge to heart transplantation in patients with complex heart failure.
• To highlight challenges in direct device comparisons and the potential role of artificial intelligence.

Main Methods:

• Review of current literature and practice patterns regarding mechanical circulatory support devices (ECMO, temporary VADs, durable VADs).
• Analysis of strategies for managing biventricular failure in the context of heart transplantation.
• Discussion of challenges in device implementation and the potential impact of emerging technologies.

Main Results:

• Significant shifts in practice patterns for mechanical circulatory support in biventricular failure.
• Difficulties in direct device comparisons due to provider and institutional learning curves.
• The field is rapidly evolving, with potential for artificial intelligence to accelerate progress.

Conclusions:

• Biventricular heart failure management requires careful consideration of mechanical circulatory support options.
• Right ventricular failure remains a critical concern with durable LVADs.
• Continued evolution and technological advancements, including AI, are expected in this field.
