Background Speckle tracking echocardiography analysis (STE) has recently allowed an in-depth analysis of right ventricular (RV) performance. The aim of the study was to observe RV function by STE in patients with advanced heart failure before and after left ventricular assist device (LVAD) implantation. Methods A transthoracic echocardiogram was performed in 19 patients referred for LVAD implant at baseline and with serial echocardiograms after LVAD implantation (Jarvik 2000). All echocardiographic images were analyzed off line by an independent operator to calculate with STE the RV free wall longitudinal strain (RVLS). Results All the patients, except 4, showed a progressive increase of RVLS after LVAD implant. However, 4 patients, who presented the lowest RVLS values at baseline, presented a further RV failure in the postoperative. The value of -11% represented the empirical preoperative cutoff able to identify patients at greater risk of postimplant RV failure. Conclusions RV myocardial deformation may have important clinical implications for the selection and management of LVAD patients. It can be used to evaluate RV function before LVAD implantation, to drive decisional strategy regarding the management of this type of patients, and after LVAD implant for the follow-up.
