Clinical context and technological evolution
Robotic surgery represents a paradigm shift in the face of the limitations of conventional laparoscopy and thoracoscopy: rigid instrumentation, restricted degrees of freedom, and 2D imaging. In cardiac surgery, the precision of intracardiac manipulations and the complexity of reconstructions demand an agility that only robotic systems — via their articulated instruments, tremor filtration, and immersive 3D visualization — can offer today. While adoption in this specialty was initially slower due to extreme technical and reproducibility requirements, the discipline is now reaching a major clinical inflection point.
Review objectives and hypotheses
This study aims to detail the evolution of current surgical platforms as well as the clinical trial data validating their use. The central hypothesis is that the transition from experimental feasibility to robust clinical validation now allows for the extension of minimally invasive techniques to complex procedures, such as aortic valve replacement (AVR) or heart transplantation, previously considered inaccessible via endoscopic ports. The review explores how the accumulation of outcome data and recent innovations, such as haptic feedback and integrated data analysis in the da Vinci 5 system (FDA approved in 2026), are transforming standards of care in cardiac surgery.
Methodology
This narrative review synthesizes the technological and clinical evolution of robot-assisted cardiac surgery. The authors analyze the development of surgical platforms based on a chronological examination of systems (AESOP, ZEUS, da Vinci) and the evaluation of emerging devices (Versius, Hugo, Senhance).
The summary of clinical performance is based on the compilation of data reported in the literature for various procedures:
- Mitral pathologies: Analysis of prospective series (n=300, Chitwood et al.) and comparative cohorts (n=759, Mihaljevic et al.; n>500, Une et al.), as well as a meta-analysis of 14 studies.
- Coronary revascularization: Evaluation of TECAB and hybrid procedures on cohorts ranging from initial feasibility (n≈45) to mature series (n>200).
- Aortic Valve Replacement (AVR): Analysis of results from a multicentre registry of 212 patients (Wei et al., 2024).
The analysis protocol integrates the technical characteristics of the platforms (leader-follower architecture, modularity, haptic feedback) and their regulatory status, including the July 2025 CE marking and the 2026 FDA approval for the da Vinci 5 system. The review also evaluates the training frameworks and institutional models required for the implementation of these programmes.
Clinical validation and performance of robotic platforms
Compiled data demonstrate a transition from technical feasibility to robust clinical validation, particularly for the da Vinci system. Initial feasibility studies, such as those by Boyd et al. (2000, n≈45) and Mohr et al. (1999, n>100), established the foundations for robotic coronary surgery (TECAB). The maturity of the technique is confirmed by larger series and multicentre registries.
| Author (Year) | Procedure | Sample (n) | Key results |
|---|---|---|---|
| Chitwood et al. (2008) | Mitral repair | 300 | Mortality < 1 %, durable repair |
| Mihaljevic et al. (2011) | Mitral comparison | 759 | Reduction of Length of Stay (LOS) |
| Une et al. (2014) | Mitral surgery | 500+ | Faster postoperative recovery |
| Wei et al. (2024) | Aortic Valve Replacement (AVR) | 212 | Mortality 0.9%, zero conversion |
Technological evolution is marked by the approval of the da Vinci 5 system (CE marking in July 2025, FDA 510(k) in 2026). This platform introduces haptic force feedback and integrated data analysis via digital recording of surgical movements. Comparatively, emerging platforms show a lower level of evidence in cardiac surgery:
- Versius (CMR Surgical): Modular architecture, but limited clinical data in cardiothoracic surgery (mainly general and gynecological use).
- Hugo™ RAS (Medtronic): Increasing international use in urology, but specific evidence for cardiac surgery remains rare (investigational status).
- Senhance (Asensus Surgical): Distinguishes itself through its reusable instruments and haptic feedback, targeting a different economic model.
Comparative studies, notably that of Mihaljevic et al. on 759 patients, highlight that while clinical outcomes are similar to sternotomy, the robotic approach significantly reduces perioperative morbidity and accelerates the return to normal activity.
Robotic inflection: from feasibility to clinical validation
This review highlights a decisive turning point: robotic cardiac surgery is no longer an experimental curiosity. Data accumulated over two decades confirm that the totally endoscopic approach now allows for the performance of complex procedures, particularly mitral repairs and coronary artery bypass grafting, with a precision unattainable by conventional laparoscopy. The major advantage lies in the removal of physical constraints: where rigid instrumentation limited the maneuver, articulated systems with tremor filtration offer superior intra-cardiac freedom of movement.
Technological evolution, marked by the arrival of the da Vinci 5 system, directly addresses one of the historical criticisms of robotics: the lack of tactile sensation. The integration of haptic feedback and digital data analysis allows the surgical gesture to be transformed into an analytical recording. This advancement, coupled with optimized ergonomics, suggests an improvement in surgical control, although adoption in our specialty remains slower than in other disciplines due to the extreme technical requirements of intracardiac surgery.
The main limitation identified remains the disparity between platforms. While the modularity of new systems is attractive for operating room organization and thoracic access, the historical system remains the only one benefiting from reproducible multi-institutional validation. The success of a robotic program therefore does not depend solely on the machine, but on the implementation of rigorous training frameworks and institutional models, essential pillars for ensuring high-quality results.
Synthesis
This review confirms that robotic cardiac surgery is reaching an inflection point, with established clinical validation for mitral repairs and coronary procedures. Current technological evolution, marked by the integration of haptic feedback and data analysis, aims to remove the final barriers to widespread adoption.
In concrete terms, for the practitioner:
- Prioritize technological precision: Use articulated instruments to secure complex intracardiac reconstructions, where 3D vision and tremor filtration are critical for the clinical outcome.
- Adopting haptic feedback: The arrival of platforms with force feedback makes it possible to compensate for the lack of tactile sensation, a major asset for the safety of tissue manipulation and the precision of sutures.
- Harnessing data-driven surgery: Use the digital motion capture capabilities of new systems to audit your surgical protocols and accelerate team training through data analysis.
Technical lexicon of robotic cardiac surgery
Leader–follower architecture: The operational core of the system; a configuration where the follower arms instantaneously replicate commands from the leader console, ensuring fluid and intuitive responsiveness.
Haptic force feedback: Sensation feedback; an innovation of the da Vinci 5 that artificially recreates tissue resistance under the instrument, finally bridging the tactile gap inherent to telesurgery.
EndoWrist: Augmented agility; these articulated instruments transcend the limits of rigid laparoscopy by offering degrees of freedom and a range of motion superior to the human wrist.
Tremor filtration: Absolute stability; a critical algorithm that neutralizes the practitioner's physiological micro-tremors to ensure unalterable surgical precision on millimetric structures.
Motion scaling: Multiplied precision; this technology converts large manual movements into surgical micro-gestures, optimizing control finesse during delicate reconstructive phases.
Totally endoscopic procedures: The ultimate minimally invasive approach; complex cardiac procedures performed exclusively via millimetric ports, eliminating the need for sternotomy or open thoracotomy.
Cardiopulmonary bypass: The historical foundation; an extracorporeal circulation system used to maintain systemic oxygenation while immobilizing the heart to allow intracardiac procedures.
