Worldwide Chronic Retrieval Experience of Helix-Fixation Leadless Cardiac Pacemakers.

Background: The growing use of leadless pacemaker (LP) technology requires safe and effective solutions for retrieving and removing these devices over the long term.

Objectives: This study sought to evaluate retrieval and removal of an active helix-fixation LP studied in worldwide regulatory clinical trials.

Methods: Subjects enrolled in the LEADLESS II phase 1 investigational device exemption, LEADLESS Observational, or LEADLESS Japan trials with an attempted LP retrieval at least 6 weeks postimplantation were included.

Reimplantation of Thymus at the First Superior Cavo-Pulmonary Anastomosis and Its Outcome.

During bidirectional cavo-pulmonary anastomosis (bidirectional Glenn; BDG), the thymic tissue is often excised to facilitate the exposure of the superior vena cava and its junction with the innominate vein. Subsequently, it is discarded. Since the last two decades, the lead author (ST) has pursued anchoring the excised thymus in its position by suturing it to the opposite unexcised thymic lobe.

Percutaneous Coronary Intervention (PCI) in Patients of Rheumatoid Arthritis(RA): A Systematic Review and Meta-Analysis.

Aim: The present study aims to investigate the outcomes of Percutaneous coronary intervention (PCI) in patients with Rheumatoid arthritis (RA).

Methods: A systemic search was conducted from electronic databases (PubMed/Medline, Cochrane Library, and Google Scholar) from inception to 15 September 2023. All statistical analyses were conducted using Review Manager 5.

Comparing pulsed field ablation and thermal energy catheter ablation for paroxysmal atrial fibrillation: a cost-effectiveness analysis of the ADVENT trial.

Background: Pulsed field ablation (PFA) has emerged as an effective technology in the treatment of paroxysmal atrial fibrillation (AF).

Objective: To evaluate the cost-effectiveness of PFA vs. thermal ablation from a US healthcare payer perspective using data from a randomized trial.

Primitive Myxoid Mesenchymal Tumor of Infancy: A Lost Battle.

Primitive myxoid mesenchymal tumor of infancy (PMMTI) is a low to intermediate-grade, poorly differentiated myofibroblastic tumor and is characterized by its tendency to recur locally. It commonly occurs in the 1 year of life and is predominantly seen in the axial skeleton and rarely in the retroperitoneum. We report one such case of PMMTI, which is the second case reported in English literature.
