Mini- and Micro-Invasive Approaches in Cardiac Surgery: Current Techniques, Outcomes, and Future Perspectives

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Techniques
• Interventional Cardiology

Background:

• Cardiac surgery has evolved from sternotomy to minimally invasive (MICS) and micro-invasive approaches.
• These techniques aim to reduce trauma, pain, and recovery time while maintaining therapeutic efficacy.
• MICS is now standard for various procedures, including valve surgery and bypass grafting.

Purpose of the Study:

• To review the evolution and current state of minimally and micro-invasive cardiac surgery.
• To highlight advancements and their impact on patient outcomes and recovery.
• To discuss the challenges and future directions in the field.

Main Methods:

• Review of randomized trials and observational studies on MICS and transcatheter interventions.
• Analysis of technological advancements like sutureless valves, robotics, and imaging.
• Discussion of hybrid procedures and patient selection criteria.

Main Results:

• MICS demonstrates comparable mortality and morbidity to conventional surgery, with benefits for high-risk patients.
• Transcatheter interventions (TAVI, mitral repair/replacement) offer alternatives for non-surgical candidates.
• Advancements improve precision, recovery, and cosmetic outcomes.

Conclusions:

• Minimally and micro-invasive cardiac surgery represent a paradigm shift towards patient-centered care.
• These approaches offer reduced physiological burden and improved functional recovery.
• Continued innovation in technology and patient selection will further integrate these techniques into standard practice.
