Right lateral access robotic aortic valve replacement (RAVR) may represent a significant advancement in minimally invasive cardiac surgery. This review examines RAVR's development, technical specifications, clinical outcomes, and future trajectory in cardiac surgery. Multicenter RAVR experiences have demonstrated promising results with low rates of operative mortality (0.9%), stroke (0.9%), and permanent pacemaker placement (2.9%). In propensity-matched comparisons with transcatheter aortic valve replacement (TAVR), RAVR had significantly lower rates of paravalvular leak (0.7% 21.5%) and one-year mortality (1.4% 12.5%). With a 3-cm working incision at the level of the anterior axillary line, the lateral access approach offers distinct advantages including improved surgical visualization, reduced tissue trauma, and standardization potential across various cardiac procedures. While learning curve considerations exist, these are minimal for experienced robotic mitral teams. RAVR programs have expanded to include implementation of complex procedures such as aortic root enlargement. As robotic systems become more prevalent and surgical expertise grows, RAVR shows promise to evolve from an innovative technique to a standard therapeutic option in aortic valve surgery. This evolution, supported by growing clinical evidence and technological advancement, positions RAVR as a potentially transformative development in cardiac surgery, offering patients the benefits of minimally invasive approaches while maintaining the durability of traditional surgical valve replacement.
右侧入路机器人辅助主动脉瓣置换术(RAVR)可能代表了微创心脏手术的一项重大进展。本综述探讨了RAVR在心脏手术中的发展、技术规格、临床结果和未来发展轨迹。多中心RAVR经验显示出了令人鼓舞的结果,手术死亡率(0.9%)、中风(0.9%)和永久起搏器植入率(2.9%)较低。在与经导管主动脉瓣置换术(TAVR)的倾向匹配比较中,RAVR的瓣周漏发生率(0.7%对21.5%)和一年死亡率(1.4%对12.5%)显著更低。通过在前腋前线水平做一个3厘米的手术切口,外侧入路方法具有明显优势,包括改善手术视野、减少组织创伤以及在各种心脏手术中实现标准化的潜力。虽然存在学习曲线方面的考虑,但对于经验丰富的机器人二尖瓣手术团队来说这些影响很小。RAVR项目已扩展到包括实施诸如主动脉根部扩大等复杂手术。随着机器人系统变得更加普及且手术专业知识不断增长,RAVR有望从一种创新技术演变为主动脉瓣手术的标准治疗选择。这种演变在越来越多的临床证据和技术进步的支持下,使RAVR成为心脏手术中一项潜在的变革性发展,在为患者提供微创方法益处的同时,保持传统手术瓣膜置换的耐久性。
