The robotic revolution in cardiac surgery

摘要

Robotic-assisted cardiac surgery (RACS) is revolutionizing the landscape of cardiovascular interventions through technological precision, minimally invasive techniques, and improved clinical outcomes. Despite its rapid expansion, significant gaps remain regarding standardization, cost-efficiency, surgeon learning curves, and patient-centered outcomes. The study critically examines current innovations, evaluates comparative clinical and economic impacts, and synthesizes key trends and contradictions from 26 recent studies. The objective is to assess the clinical efficacy, scalability, and systemic implications of RACS across diverse procedures, such as mitral valve repair, coronary artery bypass grafting, and emerging robotic heart and congenital surgeries. Employing a mixed-methods approach, including qualitative analysis of patient experiences and quantitative evaluation of national databases and long-term outcomes, the review integrates systematic reviews, case studies, and meta-analyses for a comprehensive comparative synthesis. Findings highlight superior perioperative outcomes, faster recovery, and reduced complication rates in RACS compared to the conventional surgery. Robotic proficiency correlates strongly with surgical volume, institutional infrastructure, and interdisciplinary training, while economic evaluations remain mixed, indicating higher upfront costs but potential long-term savings. Notably, patient satisfaction is consistently high due to reduced invasiveness and faster rehabilitation yet concerns about accessibility and healthcare equity persist. Contradictory evidence surrounds the cost-benefit balance in low-volume centers and the influence of patient complexity on the learning curve, although emerging evidence suggests that these factors are becoming less prohibitive with experience and technological refinement. The review identifies gaps in multicenter longitudinal studies, standard training frameworks, and integration of Internet of Robotic Things (IoRT) in clinical workflows. It recommends expanding global data-sharing platforms, refining robotic surgical curricula, and enhancing AI-driven support systems for precision guidance. The implications span patient care quality, surgical education, healthcare economics, and future robotic innovations. Limitations include potential publication bias and underrepresentation of low-resource settings. Future research should focus on longitudinal, multicentric trials evaluating robotic outcomes across different demographics, procedures, and healthcare infrastructures. In conclusion, the robotic revolution in cardiac surgery promises transformative advances, yet requires coordinated global efforts to bridge disparities, optimize training, and validate its long-term value in complex cardiovascular care.
