Robotics in valvular surgery: 2003 and beyond.

PURPOSE OF REVIEW: Currently, cardiac surgery is an evolving field. Not only has there been a technologic explosion, but there is also a strong interest in minimally invasive operations. Mitral valve surgery can now be performed with the use of sophisticated robotic systems through small incisions, and a review of recent advances is warranted. RECENT FINDINGS: Various groups have now documented that robotic valve surgery is feasible and safe. Despite an initial learning curve, facility with the procedure is gained with increasing experience. SUMMARY: Robotic mitral valve surgery is a procedure that is gaining widespread popularity. The patient of today and the future will demand minimally invasive operations. Initial clinical experience with robotic systems will allow further developments. Ultimately, this may result in completely endoscopic heart surgery.

Robot-assisted sutureless minimally invasive mitral valve repair.

Our institution has performed over 100 robot-assisted mitral valve repairs. The procedure has shown many advantages to conventional sternotomy-based repair. However, the robotic approach leads to longer cross-clamp and bypass times than conventional sternotomy. As a result of the increased risk of myocardial damage and arrhythmias from lengthy arrest times, nitinol U-clips have been used in the laboratory and currently in patients for the tissue-annuloplasty ring approximation. The technology replaces the time-consuming task of knot tying, as well as provides better visualization during placement of the annuloplasty ring. The animal studies show excellent tissue incorporation. Short-term echocardiographic imaging shows durability without evidence of mitral stenosis or regurgitation. Further studies are ongoing in our patient population, and the data suggest shorter, more efficient and effective robot-assisted mitral valve repairs.

The evolution of and early experience with robot-assisted mitral valve surgery.

Cardiac surgeons have embraced minimally invasive surgery with warranted enthusiasm. The acceleration of technological advances in optics, instrumentation, and cardiopulmonary bypass has allowed safe, effective, efficient minimally invasive cardiac procedures. In this article we review the evolution of and early experience with robot-assisted mitral valve surgery. Articles by leaders in the field of minimally invasive cardiac surgery, both American and European, are reviewed to describe the development of cardiac robotic surgery. The current state of robotic mitral surgery is described.
