New Clinical Advances in Minimally Invasive Coronary Surgery

Abstract

Background: Minimally invasive coronary surgery (MICS) has emerged as an alternative approach in the surgical management of coronary artery disease (CAD), offering potential advantages such as reduced surgical trauma, shorter hospital stays, and faster recovery. While conventional coronary artery bypass grafting (CABG) remains the standard treatment for severe CAD, MICS has seen variable adoption due to concerns over procedural complexity, the risk of incomplete revascularization, and the increasing role of percutaneous interventional techniques. Objectives: This review examines recent clinical developments in MICS, analyzing its techniques, technological advancements, and the impact on patient outcomes, while also addressing its limitations. Methods: This narrative review incorporates studies from PubMed, tracing the evolution of coronary surgery, the refinement of minimally invasive approaches, and the innovations that have enabled the selective implementation of MICS. This review evaluates robot-assisted coronary surgery and totally endoscopic coronary revascularization, discussing their clinical indications and comparative outcomes. Results: Advances in imaging, surgical instrumentation, and anesthesia have improved procedural safety and precision, yet MICS remains a selectively utilized technique rather than a universally preferred alternative. Comparative studies demonstrate mixed clinical outcomes, highlighting both the recovery benefits and technical challenges associated with MICS. Discussion: Patient selection, preoperative planning, and individualized surgical strategies play a crucial role in optimizing the effectiveness of MICS. Challenges include technical complexity, integration into broader clinical practice, and the need for procedural refinement. While ongoing research continues to address these hurdles, the role of MICS in CAD management remains context-dependent, influenced by case complexity and institutional expertise. Conclusion: MICS presents an evolving surgical approach with defined benefits and limitations, requiring careful patient selection and procedural optimization for the best outcomes. This review provides a comprehensive evaluation of recent advances in MICS while acknowledging its challenges and selective application in coronary surgery.
