Surgical approaches for single ventricle palliation

Area of Science:

• Congenital heart disease
• Pediatric cardiology
• Cardiac surgery

Background:

• Univentricular heart (UVH) encompasses complex cardiac malformations with a functionally single ventricle.
• Surgical management of UVH has evolved significantly, aiming for improved outcomes in complex pediatric cases.

Purpose of the Study:

• To discuss the evolution of surgical management for univentricular hearts.
• To outline indications, selection criteria, and operative approaches for staged palliation in UVH.
• To describe specific surgical techniques, including bidirectional cavopulmonary anastomosis and total cavopulmonary connection.

Main Methods:

• Review of the evolution of surgical techniques for univentricular hearts.
• Description of staged palliation strategies.
• Detailed explanation of the technique for bidirectional cavopulmonary anastomosis.
• Explanation of total cavopulmonary connection using an extracardiac conduit.

Main Results:

• The document outlines a comprehensive approach to the surgical management of univentricular hearts.
• Specific techniques for staged palliation are described, offering insights into operative methods.
• The use of extracardiac conduits in total cavopulmonary connection is detailed.

Conclusions:

• Staged palliation offers a viable surgical strategy for complex univentricular heart malformations.
• The described techniques, including bidirectional cavopulmonary anastomosis and total cavopulmonary connection, represent advancements in UVH surgical management.
