Novel intraoperative evaluation for mitral valve regurgitation: retrograde cardioprotective beating test.

Author information

  • 1Department of Cardiovascular Surgery, Sapporo Medical University School of Medicine, Sapporo, Japan.


In mitral valvuloplasty, the saline injection test is commonly employed. However, discrepancies in regurgitation between the naked eye findings during the saline injection test and the postoperative echocardiographical findings are noted. Here, we describe a technique that allows direct transatrial evaluation of the valve in the fully loaded, beating heart without the risks of air embolism. Physiological systolic mitral valve movement is reproduced under aortic cross-clamping. This novel evaluation enables a complete and safe mitral valve repair.
