Article Synopsis
- Device-related thrombosis (DRT) occurs frequently after left atrial appendage closure (LAAC), with notable differences in diagnosis timing and outcomes between men and women.
- Women make up 34.7% of DRT patients in the study and tend to be older and have fewer comorbidities compared to men, but DRT in women is diagnosed significantly later.
- Both genders have similar treatment outcomes and overall mortality rates, indicating that treatment strategies are equally effective regardless of sex.
Article Synopsis
- Device-related thrombus (DRT) after left atrial appendage closure (LAAC) increases the risk of serious outcomes like ischemic stroke and systemic embolism (SE), with limited data on risk factors for these events.* -
- A study involving 176 patients revealed that 14.2% experienced stroke/SE related to DRT, often occurring within 198 days of DRT diagnosis, with significant occurrences within a month before or after diagnosis.* -
- Patients with symptomatic DRT showed lower heart function and a higher prevalence of atrial fibrillation, but the challenge remains in effectively identifying clear risk factors for stroke/SE, indicating a need for future research.*
Background: The subcutaneous implantable cardioverter-defibrillator (S-ICD) has been designed to overcome lead-related complications and device endocarditis. Lacking the ability for pacing or resynchronization therapy its usage is limited to selected patients at risk for sudden cardiac death (SCD).
Objective: The aim of this single-center study was to assess clinical outcomes of S-ICD and single-chamber transvenous (TV)-ICD in an all-comers population.
Background: Data on Device-related Thrombus (DRT) after left atrial appendage closure (LAAC) remain scarce. This study aimed to investigate risk factors for DRT from centers reporting to the EUROC-DRT registry.
Methods: We included 537 patients (112 with DRT and 425 without DRT) who had undergone LAAC between 12/2008 and 04/2019.
Introduction: Visually guided laser balloon (LB) catheter has been an established modality dedicated for pulmonary vein (PV) isolation in patients with atrial fibrillation. The newly updated version of this novel device has technically evolved recent years.
Areas Covered: This review will summarize the contemporary technical evolution of LB catheter.
Background: The endoscopic ablation system (EAS) is an established ablation device for pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF). The novel X3 EAS is now equipped with a contiguous circumferential ablation mode (RAPID mode).
Aim: To determine the feasibility of single-shot fashioned ablation using X3.
Background: The second- and third-generation endoscopic ablation systems (EAS2 and EAS3) have been launched in recent years. We aimed to assess the lesion durability as well as gap localization using the multigenerational novel technologies in patients with recurrent atrial fibrillation (AF).
Methods: Consecutive patients who underwent second ablation for recurrent AF following the initial pulmonary vein isolation (PVI) with EAS2 or EAS3 were retrospectively investigated.
Background: Left atrial appendage closure is an established therapy in patients with atrial fibrillation. Although device-related thrombosis (DRT) is relatively rare, it is potentially linked to adverse events. As data on DRT characteristics, outcome, and treatment regimen are scarce, we aimed to assess these questions in a multicenter approach.
