Anaesthesia for minimally invasive cardiac surgery

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Techniques

Background:

• Minimally invasive cardiac surgery (MICS) encompasses both extracardiac and intracardiac procedures.
• Extracardiac procedures like coronary artery bypass grafting are often performed on a beating heart.
• Intracardiac procedures utilize cardiopulmonary bypass and are accessed via minithoracotomy or ministernotomy.

Purpose of the Study:

• To review the techniques and challenges associated with minimally invasive cardiac surgery.
• To highlight the importance of patient selection for optimizing outcomes.
• To discuss management strategies for potential complications.

Main Methods:

• Review of extracardiac and intracardiac procedures.
• Discussion of surgical approaches including thoracoscopic video-assisted and port-access surgery.
• Analysis of challenges related to cardiopulmonary bypass, myocardial protection, and patient management.

Main Results:

• MICS requires specific positioning for cardiopulmonary bypass and may involve suction augmentation.
• Challenges include managing arrhythmia, hemostasis, myocardial protection, and de-airing due to limited exposure.
• Potential complications arise from prolonged single-lung ventilation and limited access for interventions.

Conclusions:

• Patient selection is critical to minimize intra-operative and post-operative complications.
• Management of challenges such as prolonged ventilation and limited access requires specific strategies.
• The need for versatile analgesic techniques is emphasized due to potential conversion to sternotomy or portal extension.
