Abstract

Robotic assisted aortic valve surgery is still challenging and debatable. We retrospectively reviewed our cases of robotic assisted aortic valve replacement utilizing sutureless aortic valve with following surgical technique: 3 ports, 1 for endoscope and 2 for the robotic arms were inserted in the right chest and da Vinci Si robotic system (Intuitive Surgical, Sunnyvale, CA, USA) was adapted to these ports. Cardiopulmonary bypass was initiated through peripheral cannulations. A vent cannula was placed through the right superior pulmonary vein and a cardioplegia cannula in the ascending aorta. After cardioplegic arrest following aortic cross-clamp, the aortic valve was exposed through a clam shell aortotomy. Valvectomy along with decalcification was performed. Next using 3 guiding sutures the Perceval S valve (LivaNova, London, UK) was parachuted down and deployed. After confirming valve position, the aortotomy was closed. There were no major complications during the procedures and no conversion to sternotomy. Exposure of aortic valve was of high quality. Valvectomy required assistance with long scissors by the bedside surgeon for excision of the severely calcified valve cusps and effective decalcification of annulus. Postoperative convalescence was uncomplicated except for postoperative atrial fibrillation in 1 patient. Robotic assistance in aortic valve procedure enabled excellent exposure of the aortic valve and improved manipulation and suturing of the aortic annulus and aorta. There needs to be improvement of instrumentation for valve debridement and removal of calcium from the annulus. In addition, the sutureless valve technology contributes to the feasibility and the efficacy of this procedure.
