Robotic-assisted left atrial ligation for stroke reduction in chronic atrial fibrillation: a case report.

Patients with atrial fibrillation are at significant risk for sustaining a thromboembolic stroke. More than 90% of thromboemboli form in the left atrial appendage. Ligation of the left atrial appendage to reduce the risk of stroke is often performed in connection with other cardiac surgical procedures. As a stand-alone procedure, however, left atrial ligation has generally been deemed too invasive and has gained little support as an alternative therapeutic option. We report a case of port-access robotic-assisted left atrial ligation as a stand-alone procedure in a patient with chronic atrial fibrillation in whom anticoagulation was a contraindication. To our knowledge, this is the first reported case of stand-alone robotic-assisted left atrial ligation in the literature.

Computer-enhanced telemanipulation in mitral valve repair: preliminary experience in Canada with the da Vinci robotic system.

BACKGROUND: Investigation into the surgical application of robot technology continues to expand. We report on the first case series of robotic-assisted mitral valve (RAMV) repair in Canada with use of the da Vinci telemanipulation system (Intuitive Surgical, Sunnyvale, Calif.). METHODS: Between February 2004 and August 2004, 10 patients with normal left ventricular function and severe mitral valve regurgitation underwent RAMV repair with use of the da Vinci system. Peripheral cardiopulmonary bypass, transthoracic aortic cross-clamping and antegrade cardioplegia were used in all cases. A minithoracotomy in the fourth intercostal space and 2 ports in the third and fifth intercostal spaces allowed surgical access. All mitral valve valvuloplasties and band annuloplasties were done endoscopically with robotic assistance. RESULTS: Nine of 10 patients had successful valve repair, and 1 had conversion to mitral valve replacement due to persistent regurgitation. There were no deaths, strokes or need for sternotomy. One patient required re-exploration for bleeding. CONCLUSION: Minimally invasive RAMV repair is feasible and safe with promising early postoperative results when performed by experienced surgical personnel accomplished in both mitral valve procedures and robotic techniques.

Concurrent robotic hybrid revascularization using an enhanced operative suite.

Hybrid myocardial revascularization combines coronary surgery with percutaneous intervention as an alternative therapy for ischemic heart disease. The order and sequence of the hybrid approach is not yet clearly defined. We report on the benefits of an enhanced surgical suite equipped with a carbon fiber operating table and digital C-arm for robotic-assisted hybrid revascularization in a single operative sequence. To our knowledge, this is the first reported case of concurrent robotic-assisted hybrid revascularization utilizing an enhanced operative suite.
