Atrial Secondary Tricuspid Regurgitation: Insights Into the EuroTR Registry.
JACC Cardiovasc Interv

Article Synopsis
- Atrial secondary tricuspid regurgitation (A-STR) is a subtype of secondary tricuspid regurgitation (STR) that is often treated with transcatheter tricuspid valve edge-to-edge repair (T-TEER), showing distinct patient characteristics and treatment outcomes.
- A study involving 641 patients revealed that 31% had A-STR, which was linked to better heart function, a higher presence of atrial fibrillation, and more effective TR reduction post-procedure compared to nonatrial STR patients.
- A-STR patients experienced improved survival rates and lower symptomatic burdens after treatment; only 38% remained symptomatic (NYHA class ≥III) after 2 years, compared to 46
Aims: Conventional parameters of right ventricular (RV) function are load-dependent and therefore do not accurately reflect contractility in patients with relevant tricuspid regurgitation (TR). RV adaptability to load has been characterized using the Dandel's index in patients with heart failure, but its prognostic value in patients undergoing tricuspid transcatheter edge-to-edge repair (T-TEER) has not been investigated so far.
Methods And Results: From the EuroTR registry (2019 to 2022), patients with complete datasets and a minimum of 2-years of follow-up were included.
Article Synopsis
- The study aimed to compare the quality of life (QoL) between prostate cancer patients who recover testosterone levels after androgen deprivation therapy (ADT) and those who do not.
- The analysis involved 494 patients from a Phase III trial, looking at QoL measurements over time, with findings showing that patients with testosterone recovery reported a significantly better QoL compared to those without recovery.
- Results indicated that testosterone recovery occurred faster in patients who underwent a shorter 18-month ADT regimen, and this recovery was linked to improvements in various QoL measures.
To gain further insight into the conformational properties of small cyclic peptides that bind to the G-protein coupled receptor C5aR1, we report here for the first time the elucidation of three peptide solution conformations using residual dipolar couplings and NMR temperature coefficients. Each of these peptides varies by at least one amino acid, adopts a different intramolecular hydrogen bonding pattern, and has a different solution conformation. The solution conformations were used in combination with a homology structure of C5aR1 as a design template for increasing the potency of peptide leads for the C5a receptor.
