title: Robotic resection of dual accessory mitral valve tissue in an adult patient.
abstract: The presence of isolated accessory mitral valve tissue (AMVT) is extremely rare in adults. We successfully performed robot-assisted resection of dual AMVT that was attached to the papillary muscle and anterior mitral leaflet. Echocardiography was invaluable for identifying the most suitable approach. The short-axis view on echocardiography revealed the precise location where the AMVT was attached. The robotic operation enabled fine visualization; we clearly observed the AMVT and removed its entire extra structure. The patient recovered well and was discharged 3 days after the operation. To the best of our knowledge, this is the first report of successful robotic AMVT resection.
