Right ventricular subclinical dysfunction in high-burden idiopathic outflow tract premature ventricular contraction population.
J Interv Card Electrophysiol
January 2025
Divison of Arrhythmia, Cardiology and Vascular Department, St. David's Medical Center, Austin, TX, USA.
Background: The relationship between premature ventricular contractions (PVC) and right ventricular (RV) function is not widely known. Left ventricular (LV) dysfunction due to PVC is known as PVC-induced cardiomyopathy (PIC) and suppressing the PVC substrate would improve LV function. The effect of PVC ablation on changes in RV function in patients with subtle RV subclinical dysfunction remains unknown.

To assess the efficacy and safety of "one-stop" procedures combining radiofrequency catheter ablation and left atrial appendage closure by guidance of intracardiac echocardiography(ICE) in elderly patients with atrial fibrillation. A retrospective cohort study was conducted on patients who underwent ICE-guided "one-stop" procedures at the Department of Cardiology, General Hospital of Northern Theater Command between December 2020 and January 2023. Patients were divided into elderly group (age≥60 years old) and non-elderly group (age 18-59 years old).

Atrial fibrillation (AF), the most common type of heart arrhythmia, is recognized as an independent risk factor for stroke. Fortunately, catheter ablation (CA) offers an effective treatment option for AF patients. However, numerous studies have reported suboptimal outcomes, as AF recurrence rates often remain elevated even after CA.

Department of Radiology, Universidade Federal de São Paulo (UNIFESP), Rua Dr. Ovidio Pires de Campos, 75, Cerqueira César, São Paulo, SP, 05403-010, Brazil.
Purpose: To evaluate the feasibility, safety, and short-term (3-month) results of transperineal prostate thermal ablation (TPTA) as a minimally invasive outpatient treatment for benign prostatic hyperplasia (BPH).
Materials And Methods: A prospective nonrandomized study of 25 patients with lower urinary tract symptoms secondary to BPH seeking care at 2 interventional radiology centers between March and July 2024. TPTA was performed using a 17G radiofrequency needle with a 10-mm active tip under unconscious sedation combined with bilateral perineal and periprostatic nerve blocks.
Pulmonary artery denervation by noninvasive stereotactic radiotherapy: a pilot study in swine models of pulmonary hypertension.

Department of Cardiology, Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, Shanghai, China.
Catheter-based pulmonary artery denervation (PADN) has achieved promising outcomes to treat pulmonary hypertension (PH). We herein present stereotactic body radiotherapy (SBRT) as a novel noninvasive approach for PADN. A single fraction of 15 Gy, 20 Gy or 25 Gy was delivered for PADN in a thromboxane A2 (TxA2) - induced acute PH swine model.
