Introduction: Ablation of ventricular tachycardias (VTs) in patients with structural heart disease (SHD) has been associated with advanced heart failure and poor survival.
Methods And Results: This matched case-control study sought to assess the difference in survival after left ventricular assist device (LVAD) implantation and/or heart transplantation (HTX) in SHD patients undergoing VT ablation. From the initial cohort of 309 SHD patients undergoing VT ablation (187 ischemic cardiomyopathy, mean age 64 ± 12 years, ejection fraction of 34 ± 13%), 15 patients received an LVAD and nine patients HTX after VT ablation during a follow-up period of 44 ± 33 months. Long-term survival after LVAD did not differ from the matched control group (p = 0.761), although the cause of lethal events was different. All post-HTX patients survived during follow-up.
Conclusion: In this matched case-control study on patients with SHD undergoing VT ablation, patients that received LVAD implantation had similar survival compared to the control group after 4‑year follow-up, while the patients with HTX had a significantly better outcome.

Same-day discharge strategy in a heart rhythm management clinic: The patient-reported experience.
Arch Cardiovasc Dis
December 2024
Heart Rhythm Management Department, Clinique Pasteur, Toulouse 31076, France. Electronic address:
Background: Same-day discharge (SDD) has been adopted for interventional cardiology procedures, however, data on patient experience are scarce.
Aims: To investigate patient-reported experience after various SDD electrophysiology procedures.
Methods: Consecutive patients undergoing electrophysiology procedures, who fulfilled pre-defined eligibility criteria for SDD, completed the questionnaire before discharge.

Department of Cardiology, Fujita Health University 1-98 Dengakugakubo, Kutsukake-cho, Toyoake, Aichi 4701192, Japan.
Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2is) reportedly decreased the new-onset atrial arrhythmias in patients with type-2 diabetes (T2DM) or heart failure (HF). This study examined the impact of SGLT2is on catheter ablation for atrial fibrillation (AF) in HF patients without T2DM.
Methods: Persistent AF (PeAF) and HF (N-terminal prohormone of brain natriuretic peptide, NT-proBNP ≥400 pg/ml) patients without T2DM undergoing catheter ablation were prospectively enrolled (n = 102).

Purpose: This study aims to evaluate the prognostic value of contrast-enhanced ultrasound (CEUS) combined with tumour markers in patients with hepatocellular carcinoma (HCC) undergoing microwave ablation (MWA).
Methods: MWA patients with HCC were divided into good prognosis (n = 75) and poor prognosis (n = 69) groups. The levels of alpha-fetoprotein (AFP), carbohydrate antigen (CA19-9), and carcinoembryonic antigen (CEA) before and after MWA were analysed using an independent sample t-test.
Glutathione accelerates the cell cycle and cellular reprogramming in plant regeneration.

The plasticity of plant cells underlies their wide capacity to regenerate, with increasing evidence in plants and animals implicating cell-cycle dynamics in cellular reprogramming. To investigate the cell cycle during cellular reprogramming, we developed a comprehensive set of cell-cycle-phase markers in the Arabidopsis root. Using single-cell RNA sequencing profiles and live imaging during regeneration, we found that a subset of cells near an ablation injury dramatically increases division rate by truncating G1 phase.

Research Department, Valley Vein Health Center, Turlock, CA, USA.
Purpose: Determine the rate of incidence, risk factors, and management for developing venous thromboembolism (VTE) in patients undergoing radiofrequency ablation (RFA) and ultrasound-guided foam sclerotherapy (UGFS) for varicose veins.
Methods: All charts of patients undergoing venous ablation from 2016 to 2023 were reviewed at a rural vein treatment clinic. The incidence of VTE was noted and a chart review was completed to identify risk factors for VTE, EHIT score, EFIT score, and management.
