1 Robotic Resection of Dual Accessory Mitral Valve Tissue in an Adult Patient 
Shojiro Yamaguchi, MD, PhD, Norihiko Ishikawa, MD, PhD, Shigeyuki Tomita, MD, PhD, Hiroshi Ohtake, MD, PhD, Ryuta Kiuchi, MD, Yuji Nishida, MD, Kenichi Muramatsu, MD, Go Watanabe, MD, PhD  The Annals of Thoracic Surgery  Volume 98, Issue 3, Pages (September 2014) DOI: /j.athoracsur Copyright © 2014 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 (A) Long-axis view on transthoracic echocardiography, showing accessory mitral valve tissue (AMVT) protruding into the left ventricular outflow tract. (B) Short-axis view on transthoracic echocardiography, clearly revealing the dual AMVT.

3 Fig 2 (A) Accessory mitral valve tissue (AMVT) of the anterolateral side. (B) AMVT of the anterolateral side, forming a cystlike structure. (C) AMVT of the anterolateral side attached to the papillary muscle. (D) AMVT of the anterolateral side removed with a dick tendon.

4 Fig 3 (A) Accessory mitral valve tissue (AMVT) of the posteromedial side, first view. (B) AMVT of the posteromedial side appeared like a parachute. (C) AMVT of the posteromedial side attached to the anterior leaflet. (D) AMVT of the posteromedial side resected by use of the daVinci surgical system.
