Net atrioventricular compliance (Cn) below 2.31 ml/mmHg predicts persistent postoperative pulmonary hypertension after mitral valve replacement in severe mitral stenosis.
Does net atrioventricular compliance correlate with postoperative pulmonary artery pressure in adult patients with severe mitral stenosis undergoing surgical mitral valve replacement?
A net atrioventricular compliance cut-off of 2.3 ml/mmHg estimated by echocardiography can predict persistent pulmonary hypertension following surgical mitral valve replacement for severe mitral stenosis.

. This single-center prospective observational study aimed to assess the correlation of net atrioventricular compliance (Cn) with pulmonary artery pressure in 26 adult patients with severe mitral stenosis (MS) undergoing surgical mitral valve replacement (MVR). Cn was estimated by doppler echocardiography, and pulmonary artery pressures measured by pulmonary artery catheter. Early outcomes including duration of intensive care unit (ICU) stay, mechanical ventilation duration, and vasoactive inotropic scores (VIS) were recorded. Cn showed moderate to strong negative correlation with systolic, diastolic, and mean pulmonary artery pressures at all time points. Receiver operating characteristic (ROC) curve analysis determined a cut-off of 2.31 to predict postoperative pulmonary artery systolic pressure. Cn with a cut-off value of 2.3 ml/mmHg serves as an indicator of persistent pulmonary hypertension following MVR surgery.
