Perfusion techniques for minimally invasive valve procedures

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Cardiac Procedures
• Perfusion Techniques

Background:

• Minimally invasive cardiac surgery offers advantages over traditional sternotomy.
• Standard cardiopulmonary bypass requires specific adaptations for minimally invasive approaches.
• Efficient perfusion is critical for patient outcomes in cardiac valve surgery.

Purpose of the Study:

• To present a simplified perfusion technique for minimally invasive cardiac valvular procedures.
• To detail the methodology and application of this technique in a clinical setting.
• To evaluate the safety and efficacy of the described perfusion strategy.

Main Methods:

• Direct cannulation of the ascending aorta for arterial return.
• Percutaneous venous cannula insertion into the femoral vein.
• Antegrade delivery of crystalloid cardioplegia via a flexible aortic cross-clamp applied percutaneously.

Main Results:

• The simplified perfusion technique was successfully applied in 200 cardiac minimally invasive valvular procedures.
• Procedures were performed via a right lateral mini-thoracotomy.
• No technical complications were reported related to the perfusion method.

Conclusions:

• The simplified perfusion technique is safe and effective for minimally invasive cardiac valvular surgery.
• This approach facilitates cardiopulmonary bypass through a right lateral mini-thoracotomy.
• The technique offers a viable alternative for perfusion in selected cardiac procedures.
