Experience in using three different minimally invasive approaches in cardiac operations

Area of Science:

• Cardiac Surgery
• Minimally Invasive Procedures
• Thoracic Surgery

Background:

• Review of clinical experience with three minimally invasive cardiac surgery approaches: inferior partial median sternotomy, right anterolateral minor thoracotomy, and right parasternal approach.
• Comparison against traditional sternotomy for cardiac operations.

Purpose of the Study:

• To evaluate the clinical outcomes and feasibility of different minimally invasive approaches in cardiac surgery.
• To compare the efficacy and safety of minimally invasive cardiac operations versus sternotomy.

Main Methods:

• Retrospective analysis of 2431 sternotomy cases and 323 minimally invasive cardiac surgery cases.
• Evaluation of operative parameters including incision length, postoperative drainage, operative time, and cardiopulmonary bypass time.
• Assessment of postoperative complications associated with minimally invasive approaches.

Main Results:

• Inferior partial median sternotomy provided good exposure except for the ascending aorta. Right anterolateral minor thoracotomy and right parasternal approach offered similar exposure, primarily to the right heart structures and mitral valve.
• Minimally invasive approaches demonstrated statistically significant reductions in incision length and postoperative drainage compared to sternotomy, with no significant difference in operative or cardiopulmonary bypass times.
• The overall incidence of complications for minimally invasive cardiac surgery was 5.3%, including air embolism, chest pain, chest wall malacia, and fractures.

Conclusions:

• Minimally invasive cardiac surgery approaches can achieve satisfactory clinical results.
• Proper selection and execution of minimally invasive techniques are crucial for successful outcomes in cardiac operations.
