Robotic VT Ablation in a Rastelli Patient. Robotically assisted catheter ablation has been proven feasible in patients with a variety of atrial arrhythmias. The potential to provide improved catheter tip maneuvering and stability potentially makes it ideal for complex ablation procedures. We present the case of a patient with complex congenital heart disease with previous Rastelli repair and recurrent ventricular tachycardia (VT) who underwent robotically assisted mapping and ablation for right ventricular VT, utilizing substrate mapping techniques. © 2009 Wiley Periodicals, Inc.




“A novel internal thoracic artery harvesting technique via subxiphoid approach – For the least invasive coronary artery bypass grafting.”

We have performed 12 cases of robotically assisted coronary artery bypass grafting (CABG) to accomplish less invasive revascularization. In this report, we describe a new method of robotically assisted internal thoracic artery (ITA) harvesting via subxiphoid approach, using the da Vinci surgical system. A 22-year-old man with three-vessel coronary artery disease due to Kawasaki disease was referred to our institution for coronary artery revascularization. A small subxiphoid incision was made, and the xiphoid process at the lower end of the sternum was excised. A U-shaped hook was inserted into the retrosternal space, and the lower sternum was lifted. A 30° angle-up camera was inserted under the U-shaped hook, bilateral ITAs were harvested in a totally skeletonized fashion endoscopically. The required time for right ITA harvesting was 50 min, and that for the left was 20 min. After bilateral ITAs were harvested, composite grafts were made, and then the distal anastomoses were made. The patient was discharged six days after the operation. We performed a new robotically assisted bilateral ITA harvesting technique via sub-xiphoid safely and with excellent results. This method might be an evolutionary step of minimally invasive direct coronary artery bypass (MIDCAB) using the da Vinci surgical system.
