Cardiac robotics: a review and St. Mary's experience

Area of Science:

• Cardiovascular Surgery
• Medical Robotics
• Minimally Invasive Surgery

Background:

• Laparoscopic surgery advanced surgical procedures, enabling keyhole incisions with outcomes similar to open surgery.
• Challenges in laparoscopy, including depth perception and tactile feedback, spurred the development of robotic surgical tools.
• Robotics in surgery emerged as a solution to overcome the limitations of minimally invasive techniques.

Purpose of the Study:

• To review the history and applications of robotic surgery in cardiac procedures.
• To explore the use of robotic manipulation in mitral valve repair and coronary artery surgery.
• To assess the feasibility and outcomes of robotic cardiac surgery.

Main Methods:

• A literature search was conducted on PubMed and Medline for studies on cardiac robotic surgery.
• Twenty-one articles focusing on robotic applications in mitral valve repair and coronary artery surgery were selected.
• The review included the history, applications, telemedicine aspects, and future prospects of robotic surgery.

Main Results:

• A total of 102 robotic cardiac surgery cases were performed over 4 years.
• The mean hospital stay was 3.1 days (SD 1.4 days).
• No mortality was reported in the series, with morbidity details provided.

Conclusions:

• Minimally invasive cardiac surgery using robotics is feasible and achieves results comparable to conventional surgery.
• Robotic cardiac surgery presents a technically demanding modality for surgeons.
• Further multicenter studies are required to establish the efficacy of robotic cardiac surgery.
