Robotic Mitral Valve Repair With Using Artificial Chordae And Standardized Chordal Length Measurement System
OBJECTIVE: This video presentation describes usage of a standardized chordal length measurement system during robotic mitral valve repair with using artificial chordae
METHODS: The Davinci XI or SI systems were used for operations. The classical set up for robotic mitral operations was described before. A 3 cm incision was made between the anterior axillary line and midclavicular line at the 4th intercostal space. Peripheral cannulation was used. A complete ring with a chordal guiding system was used for both anterior and posterior (or bileaflet prolapses) with using routine artificial chordae.
RESULTS: This system has been used in 15 patients. There was no need for intraoperative reintervention for sizing of artificial chordaes. The step for implantation of artificial chordae was straightforward in all patients. There was no mitral insufficiency at the transeesophageal examination performed after the completion of cardiopulmnonary bypass.
CONCLUSIONS: This system enables a safe mitral valve repair with a standardized artificial chordal length measurement during robotic operations.
