Samenvatting

Optimal left ventricular assist device (LVAD) functioning and preservation of right ventricular (RV) function are major survival determinants in destination therapy (DT)-LVAD recipients, Currently, the indication for routine pump speed optimization in stable patients and its effect on RV function at follow-up remain underexplored, Hemodynamically stable patients (N = 17, age 61 [interquartile range {IQR} 51-66] years; 13 [77%] male) underwent a routine speed ramp test, Echocardiographic images were obtained at incremental speed settings to determine optimal pump speed, In 8 patients (47%), LVAD speed could be optimized, In these patients, RV fractional area change (26% [IQR 23-31] to 35% [IQR 27-45], p = 0.04) and RV longitudinal peak systolic strain (-13% [IQR -16 to -9] to -17% [IQR -18 to -11], p = 0.02) at 3 months follow-up improved without RV dilatation, Furthermore, N-terminal pro-brain natriuretic peptide level decreased (3,162 [IQR 1,336-4,487] ng/L to 2,294 [IQR 1,157-3,810] ng/L, p = 0.02),
