BackgroundThere is no fully recommended methodology for surgery for Barlow's disease. Various methods have been proposed. The aim of this study was to investigate the effectiveness of transesophageal echocardiography (TEE) measurements for selecting the optimal annuloplasty ring size and determining the length of artificial chordae in patients with Barlow's disease who underwent robot-assisted mitral valvuloplasty (R-MVP).MethodsTen patients were included. Before R-MVP, the anesthesiologist used TEE to predict the optimal annuloplasty ring size and artificial chordae lengths that would reduce mitral regurgitation. The anesthesiolosist's predict ring size was not presented to the surgeon intraoperatively.ResultsIn 70% (7/10) of cases, the surgeon performed mitral valve repair in full match with the anesthesiologist's repair plan. Mitral regurgitation was controlled in 85% (6/7) of cases. In three cases, the predict annuloplasty ring size and artificial chordae length were not match between anesthesiologist and surgeon. After the operation, 90% (9/10) of patients had no residual mitral regurgitation.ConclusionsAnesthesiologist's TEE measurements were useful for selecting the optimal annuloplasty ring size and artificial chordae length during R-MVP. TEE can play an important role in robot-assisted, minimally invasive cardiac surgery for mitral regurgitation with extensive and complex prolapse, such as in Barlow's disease.
