Early Deterioration of the Right Ventricular Pacing Threshold Predicts the Increase in His‐Bundle Pacing Threshold During the Chronic Phase: A Single‐Center Retrospective Study

Journal of Arrhythmia, Volume 41, Issue 4, August 2025.
We observed that an increase in the right ventricular (RV) pacing threshold tended to precede that of the His‐bundle threshold. Multivariate analysis identified two predictors of chronic threshold deterioration: an RV pacing threshold ≥ 3.0 V/0.4 ms at 1 week after implantation and the lead shape at the time of implantation.

Rotating Frame Relaxation Time Mapping for the Visualization of the Sinoatrial Node Without Contrast Agent

NMR in Biomedicine, Volume 38, Issue 8, August 2025.
In this study, we have found that SAN structure displays higher relaxation time compared to remote myocardium. TRAFF2 and T1ρ are highly correlated with SAN size determined by histology. TRAFF2 and T1ρ relaxation time maps are feasible non‐invasive methods to visualize SAN structure.

The Beneficial and Harmful Effects of Perioperative Clonidine: Protocol for a Systematic Review With Meta‐Analysis

Acta Anaesthesiologica Scandinavica, Volume 69, Issue 7, August 2025.
ABSTRACT Background Moderate to severe postoperative pain is frequent in patients undergoing surgery and is associated with increased morbidity and prolonged hospitalisation. Therefore, sufficient pain management should be prioritised. Clonidine, an alpha‐2 agonist with analgesic properties, may represent a relevant option in postoperative pain ...

Clinical Results for Cardiovascular Xenografts Treated With Novel Anticalcification Protocols

Artificial Organs, Volume 49, Issue 8, Page 1307-1313, August 2025.
This study demonstrates the safety, efficacy, and clinical performance of the tissue‐engineered Periborn bovine pericardial scaffold treated with our novel anticalcification protocols for surgical repair of a variety of cardiovascular diseases. The overall probability of freedom from Periborn‐related reoperation was 95.4% ± 3.2% at 9 years.
