New intra-operative mitral regurgitation is an unusual complication of tricuspid annuloplasty and maybe ischemic in etiology as a consequence of right coronary artery distortion. We report the case of a woman in whom this was treated by mitral valve annuloplasty with ensuing hemodynamic instability and ventricular arrhythmia secondary to a new left circumflex occlusion. Injury/distortion to either of the coronary arteries running in the atrio-ventricular groove is rare, and described only several times. To our knowledge, concurrent right coronary artery and circumflex artery injury/distortion has not been reported previously.
