The management of right heart failure during durable left ventricular assist device (LVAD) support remains an unsolved issue so far. We had a 44-year-old male patient who was diagnosed with arrhythmogenic right ventricular cardiomyopathy and received HeartMate 3 LVAD (Abbott, USA) implantation as a bridge-to-transplant indication. The pump speed was adjusted as low as 4500 rpm to avoid the left ventricular narrowing and interventricular septal leftward shift.

Background: The remote dielectric sensing (ReDS) system is a recently introduced non-invasive technology used to easily estimate the degree of lung fluid volume without any expert techniques. In the previous literature, ReDS values had a moderate correlation with invasively measured pulmonary artery wedge pressure (PAWP), the gold standard for representing left heart preload. Considering the mechanism of ReDS technology, ReDS values may be inappropriately elevated in the presence of pleural effusion (PE), and the ability of the ReDS system to estimate PAWP may decrease in such a situation.

Article Synopsis
  • Remote dielectric sensing (ReDS) is a non-invasive technology used to measure lung fluid levels, and the study explored its correlation with the six-minute walk test (6MWT) in patients with severe aortic stenosis awaiting valve replacement.
  • 25 hospitalized patients (average age 85) underwent both ReDS and 6MWT measurements, revealing a moderate inverse relationship between 6MWD and ReDS values, indicating that less walking distance was associated with higher lung congestion.
  • The findings suggest that ReDS can effectively indicate pulmonary congestion, as patients with a ReDS value ≥30% displayed significantly shorter 6MWD, thus providing a potential tool for assessing exercise capacity in this
