The primary results of the DELTA-HF trial demonstrate that the eLym System heart failure therapy provides a safe and effective method for interstitial decongestion. Managing fluid overload is often difficult in patients with acute decompensated heart failure (ADHF). Consequently, persistent congestion remains a significant risk factor for rehospitalization. However, this innovative endovenous axial pump targets the lymphatic system directly to enhance fluid removal.
The system facilitates drainage by creating a localized reduced-pressure zone at the venous angle. Specifically, the device utilizes an endovenous pump to lower pressure where the thoracic duct connects to the venous system. Furthermore, this mechanism supports the natural drainage of interstitial fluid back into the circulation. This approach differs from standard diuretics, which primarily target intravascular volume.
Notably, the trial achieved successful device deployment in all 40 participants. During the therapy period, patients lost an average of 3.6 kg. Furthermore, weight loss increased to 6.8 kg by the time of hospital discharge. Additionally, the median modified EVEREST Clinical Congestion Score improved significantly from 5.0 at baseline to 0.0 at discharge. Most importantly, kidney function remained stable throughout the treatment process.
Moreover, the study reported a low 90-day heart failure rehospitalization rate of only 9.5%. This finding is particularly encouraging compared to standard care. Consequently, the eLym system represents a promising adjunctive therapy for refractory congestion. Researchers look forward to further large-scale randomized controlled trials to confirm these benefits.
The system creates a low-pressure zone at the thoracic duct junction. This helps the lymphatic system move excess fluid from tissues into the bloodstream for excretion.
No, the DELTA-HF trial results showed that kidney function remained stable during and after the treatment. Creatinine levels and GFR did not change significantly.
In the trial, the mean therapy time was approximately 23.1 hours. Clinicians successfully deployed the device in every case with minimal complications.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
