Correlation between papillary muscle approximation to parametric improvements. A parametric improvement was defined as a beneficial Δ between preoperative and 5-year postoperative values.The correlation magnitude was evaluated with Spearman’s rho. The magnitude of correlation was high for improvements of the α and β angles, and of the tenting area. The magnitude of correlation was moderate for improvements of the LVEDD and LVESD.The magnitude of correlation was low for improvements of the PAP. Acronyms: LVEDD = left ventricular end diastolic volume; LVESD = left ventricle end systolic diameter; PAP = (systolic) pulmonary artery pressure
