Do robotic systems and laser energy provide an effective, less-invasive alternative to traditional surgical ablation for atrial fibrillation?
Robotics and laser energy represent promising, less-invasive technological advancements for surgical ablation in atrial fibrillation.
Should not yet change AF ablation practice; leaves open the need for randomized trials of laser versus heat-based energy.
BACKGROUND: The future of medicine is tied-up in robotics and lasers. We've heard the hype for years, but only in the last 10 years has it actually started to come to fruition that robotic systems are beginning to play a role in surgery. METHODS: Multiple groups have reported over the past 10 years on increasingly complex cardiac surgical procedures being performed with the aid of robotic systems. With an increasing percentage of atrial fibrillation and with insight that atrial fibrillation results in poor long-term survival, attempts have been made to create a surgical cure. RESULTS: Much work has been done in the past several years to develop a less-invasive surgical option than the standard cut-and-sew Maze to achieve pulmonary vein ablation. Laser is a unique energy source for tissue ablation because it is a form of light. CONCLUSION: While traditional energy sources focus on applying heat-based elements to the tissue's surface allowing temperature to propagate across the thickness of the tissue laser is an innovative, tissue-specific energy for creating tissue ablation.

J. Michael Smith (2006) conducted a review in Atrial fibrillation. Laser tissue ablation and robotic systems vs. Traditional heat-based energy sources was evaluated. Laser energy represents an innovative, tissue-specific alternative to traditional heat-based sources for less-invasive cardiac tissue ablation in atrial fibrillation.
