Liver stiffness obtained by ElastPQ ultrasound shear wave elastography independently determines mean right atrial pressure

Purpose We aimed to investigate the relationship between right atrial pressure (RAP) and liver stiffness (LS) determined by liver elastography (LE) during cardiac resynchronization therapy (CRT) in patients with heart failure (HF) and conventional pacemaker (PM) implantation in patients without HF....

Description
Summary:Purpose We aimed to investigate the relationship between right atrial pressure (RAP) and liver stiffness (LS) determined by liver elastography (LE) during cardiac resynchronization therapy (CRT) in patients with heart failure (HF) and conventional pacemaker (PM) implantation in patients without HF. Methods 60 patients with HF who underwent CRT and 60 patients without HF who underwent PM were enrolled. Routine echocardiography and laboratory examinations were performed. Systolic, diastolic, and mean RAP measurements were performed inversely during PM implantation and LS measurement with ElastPQ technique. Results Systolic, diastolic, and mean RAP, left ventricular (LV) systolic-diastolic, right ventricular (RV) diastolic and left atrial diameters, tricuspid regurgitation pressure gradient, and RV-myocardial performance index (MPI) values were significantly higher in patients with HF ( p   10 mmHg with 89.6% sensitivity and 87.5% specificity. Conclusions The non-invasive LS value determined by LE independently determines the mean RAP in patients with and without HF. According to our study results, > 7 kPa value for LS determined in liver US may be predictive for increased mean RAP.
