Objective: Coronary artery bypass grafting is one of the most commonly performed surgical procedures in cardiovascular surgery with a steadily evolving minimally invasive approach.
Methods: Conventional coronary artery bypass grafting (CABG) is performed traditionally via midline sternotomy. Exciting advancements in technology and engineering over the last two decades have resulted in the transition from conventional to minimally invasive CABG including robotically assisted surgery.
Results: The minimally invasive techniques are continuously striving to promote coronary revascularization into the arena of minimally invasive surgery. Examination of 10 previously completed studies with relevant follow-up periods enables an insightful vision into the outcomes and pitfalls surrounding robot-assisted CABG (RACAB) as explored in this review. Studies indicate that RACAB is associated with decreased postoperative complications such as major adverse cardiac or cerebrovascular events without compromise in survival rates. Despite this, certain drawbacks such as incurring costs and technical complexity of the procedure cannot be dismissed.
Conclusion: There exist patient-related benefits from minimally invasive techniques such as decreased certain postoperative complications. Furthermore, with experience and a specialized stepwise program, it is possible to perform the entire procedure from the console. However, certain pitfalls involving increased expenses, steep learning curve and the lack of proper haptic feedback currently withhold the worldwide expansion of RACAB and limit it to specialized institutions only.
