Table 3 Preoperative and postoperative hemodynamic parameters

From: Preoperative scallop-by-scallop assessment of mitral prolapse using 2D-transthoracic echocardiography

Variable Before surgery After surgery Relative reduction P value
Mean PAPs ± SD (mmHg) 42 ± 10.6 34 ± 6.6 19% <0.00001
Mean LVEDV ± SD (ml) 144.8 ± 42.5 107.1 ± 37.2 26% <0.00001
Mean Ejection Fraction ± SD (%) 63.9 ± 7.7 54.6 ± 8.6 14.5% <0.00001
MV mean gradient ± SD (mmHg) - 3.9 ± 1.5 - -
  1. MV, mitral valve; PAPs, systolic pulmonary artery pressure; LVEDV, left ventricle end diastolic volume.
