  • Data are presented as mean ± standard deviation.

  • LVEF, left ventricular ejection fraction; LVEDP, left ventricular end‐diastolic pressure; LVEDV, left ventricular end‐diastolic volume; MVOP, mitral valve opening pressure; E/A, ratio of Epeak and Apeak.

  • * LVEF determined by ventriculography.
