Global longitudinal strain in prosthesis-patient mismatch: relation to left ventricular mass regression and outcomes

This study was designed to investigate the association between the baseline global longitudinal strain (GLS) and the postoperative LVMR, and its relation to adverse outcomes. Methods A total of 316 patients with aortic stenosis undergoing isolated mechanical prosthesis implantation were screened, and data from 91 patients with aortic PPM and 165 non-PPM patients were retrospectively collected. All 256 patients underwent measurement of GLS by two-dimensional speckle-tracking echocardiography preoperatively, and were followed up for postoperative changes of LV mass index (LVMi) and other clinical outcomes. Results During the follow-up, LVMi in PPM patients decreased significantly from 139.6 ± 20.8 to 119.6 ± 26.5 g/m2 (P
