AB  - Mitral and aortic valve insufficiencies have been commonly reported in horses. 
      The objective of this study was to establish the use of acoustic cardiography 
      (Audicor((R))) in horses with aortic (AI) or mitral valve insufficiency (MI). A 
      total of 17 healthy horses, 18 horses with AI, and 28 horses with MI were 
      prospectively included. None of the horses was in heart failure. Echocardiography 
      and Audicor((R)) analyses were conducted. Electromechanical activating time (EMAT), 
      rate-corrected EMATc, left ventricular systolic time (LVST), rate-corrected 
      LVSTc, and intensity and persistence of the third and fourth heart sound (S3, S4) 
      were reported by Audicor((R)). Graphical analysis of the three-dimensional (3D) 
      phonocardiogram served to visually detect murmurs. Audicor((R)) snapshot variables 
      were compared between groups using one-way ANOVA followed by Tukey's 
      multiple-comparisons test. The association between Audicor((R)) snapshot variables 
      and the corresponding echocardiographic variables was investigated by linear 
      regression and Bland-Altman analyses. Heart murmurs were not displayed on 
      Audicor((R)) phonocardiograms. No significant differences were found between 
      Audicor((R)) variables obtained in clinically healthy horses and horses with 
      valvular insufficiency. The Audicor((R)) device is unable to detect heart murmurs 
      in horses. Audicor((R)) variables representing cardiac function are not markedly 
      altered, and their association with corresponding echocardiographic variables is 
      poor in horses with valvular insufficiency that are not in heart failure.
