abstract = {Background: Limited data are available on performance of the left ventricular (LV) mass equation when there is a dynamic change to LV load. We aimed to test this equation in the immediate post-operative period following aortic valve replacement (AVR) for aortic regurgitation (AR) to see if it would reliably demonstrate stable LV mass before and after surgery. Since LV mass would be unlikely to change in the immediate postoperative period, we hypothesized that a decrease in LV diameter postoperatively would be accompanied by concomitant increases in LV wall thickness as predicted by the LV mass equation.
Methods: We reviewed echocardiograms of adult patients with AR who underwent AVR from 2007–2017 at Montefiore Medical Center (n=28). Three independent readers performed septal wall thickness (SWT), posterior wall thickness (PWT) and left ventricular internal diameter (LVID) measurements on pre-operative and post-operative echocardiograms. LV masses were calculated using the American Society of Echocardiography (ASE) equation.
Results: Post-operatively, LVID decreased from 5.7±1.2 to 4.9±1.0 cm, P},
