Retrograde cardioplegia: when and how. A review

Area of Science:

• Cardiovascular Surgery
• Cardiac Anesthesia
• Myocardial Protection

Background:

• Retrograde cardioplegia is increasingly utilized due to advancements in delivery techniques.
• Balloon catheters now enable blind transatrial cannulation of the coronary sinus for retrograde delivery.
• This approach presents specific technical benefits in certain surgical scenarios.

Purpose of the Study:

• To highlight the growing popularity and technical advantages of retrograde cardioplegia.
• To explore potential benefits for specific patient subgroups, particularly those with severe coronary stenoses or occlusions.
• To position retrograde cardioplegia as a valuable addition to cardiac surgical techniques.

Main Methods:

• Utilizes balloon catheters for transatrial cannulation of the coronary sinus.
• Facilitates retrograde delivery of cardioplegic solutions.
• Describes technical advantages and potential patient benefits.

Main Results:

• Retrograde cardioplegia offers distinct technical advantages in various surgical situations.
• Potential benefits for patients with severe coronary stenoses/occlusion are suggested, though not yet clinically documented.
• The technique is considered a valuable addition to the cardiac surgeon's toolkit.

Conclusions:

• Retrograde cardioplegia is a valuable technique in cardiac surgery.
• Its utility is enhanced by advancements in cannulation methods.
• Further clinical documentation may solidify its role, especially in complex coronary artery disease cases.
