Comparison of safety and effectiveness of different sheaths in ablation of focal atrial tachycardia: a retrospective study.

Background: A novel visualized steerable sheath, referred to as the Vizigo sheath, has been utilized in clinical interventions. The objective of this study was to evaluate and contrast the efficacy and safety of the Vizigo sheath with other sheaths in the catheter ablation (CA) for focal atrial tachycardia (FAT).

Methods: A retrospective cohort study was conducted on consecutive patients with CA for FAT from March 2019 to February 2022.

Leveraging green finance and technological innovations for sustainable urban development: A comparative study of Chinese mega-cities.

Being worlds' largest population, China is the biggest consumer of natural resources and causes the highest Carbon emissions due to its energy needs for economic development. This research aims to analyze the relationship between green finance, natural resources, carbon releases, and foreign direct investment on China's efforts towards durable economic sustainability. Difference-in-Difference frameworks are utilized to analyze the statistics acquired from 270 Chinese cities between 2002 and 2022.

Association of left atrial wall thickness with recurrence after cryoballoon ablation of paroxysmal atrial fibrillation.

Background: Transmural injury plays a role in successful atrial fibrillation ablation. The effect of left atrial wall thickness (LAWT) on the efficacy of radiofrequency ablation has been identified, but data on the relationship between LAWT and cryoballoon for paroxysmal atrial fibrillation (PAF) are lacking. We aim to explore the relationship between LAWT and recurrence after cryoballoon ablation (CBA).

Left Atrial Appendage Closure for Atrial Fibrillation in the Elderly >75 Years Old: A Meta-Analysis of Observational Studies.

Background: Left atrial appendage closure (LAAC) is an established therapy for patients with atrial fibrillation (AF); however, there is a limited understanding of LAAC in elderly patients (≥75 years old). We conducted a meta-analysis to investigate the procedural complications and long-term outcomes after LAAC in the elderly versus the non-elderly. Methods: We screened PubMed, EMBASE, Cochrane Library, and Web of Science.

Metastatic patterns and prognosis of young lung cancer patients: a population-based study by age.

Background: We aimed to examine the different metastatic patterns and corresponding survival outcomes between all ages of young (aged <60 years) and elderly lung cancer patients.

Methods: Lung cancer patients from the Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2015 were divided into a young and elderly group. The young group was subdivided into four consecutive subgroups.
