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.

Successful Ethanol Infusion of Vein of Marshall With Bridge Collateral Using the Double‐Balloon Technique Incorporating a Wedged Berman Catheter

Journal of Arrhythmia, Volume 41, Issue 4, August 2025.
We describe a novel double‐balloon technique incorporating a wedged Berman catheter to manage distal collateral drainage from the vein of Marshall (VOM) via a bridge collateral to the great cardiac vein, thereby enabling effective ethanol infusion. This technique may represent a viable alternative for anatomically challenging VOM ethanol infusion cases.

Incidence of Rapid Rate Non‐Sustained and Sustained Ventricular Tachycardia in Implantable Cardioverter‐Defibrillator Recipients and Its Correlation With Heart Failure Guideline‐Directed Medical Therapy Compliance

Journal of Arrhythmia, Volume 41, Issue 4, August 2025.
Among heart failure with reduced ejection fraction (HFrEF) patients with ICD implants, over one‐third experienced rapid rate NSVT events despite guideline‐directed medical therapy (GDMT) compliance; however, sustained VT occurrence was significantly reduced with compliance—a study highlighting the protective impact of GDMT against life threatening ...

Optimization of Coronary Sinus Pacing Site Based on Cardiac Contractility Detected by a Right Atrial Lead–Embedded Accelerometer

Journal of Arrhythmia, Volume 41, Issue 4, August 2025.
A narrow QRS duration does not necessarily correlate with a high SonR value. To identify the optimal pacing site, comprehensive evaluation of all available parameters, including the use of MPP, may be necessary.

Short‐Term Results of the SONCAR Study: Optimized Neoadjuvant Chemoradiotherapy in Locally Advanced Rectal Cancer Patients

MedComm, Volume 6, Issue 8, August 2025.
This study investigates whether adding four cycles of CapOX to standard neoadjuvant chemoradiotherapy improves overall survival in patients with locally advanced rectal cancer. The results show that this combination significantly increases complete tumor response rates, particularly for tumors close to the anal verge, with manageable toxicity ...
