AI Article Synopsis
- The study assessed how daily ECG self-recordings affect the detection and treatment timing of recurrent atrial fibrillation (AF) or atrial flutter (AFL) in patients undergoing specific treatments.
- A total of 238 patients were divided into a control group receiving standard care and an intervention group using a mobile ECG device, revealing that the intervention group had a higher likelihood of detecting recurrence.
- Results indicate that while mobile ECG devices facilitate earlier detection of AF/AFL recurrences, they also showed that control patients had a shorter time from detection to treatment.
Article Abstract
Objective: This study evaluated the impact of daily ECG (electrocardiogram) self-recordings on time to documented recurrent atrial fibrillation (AF) or atrial flutter (AFL) and time to treatment of recurrent arrhythmia in patients undergoing catheter radiofrequency ablation (RFA) or direct current cardioversion (DCCV) for AF/AFL.
Background: AF recurrence rates after RFA and DCCV are 20% to 45% and 60% to 80%, respectively. Randomized trials comparing mobile ECG devices to standard of care have not been performed in an AF/AFL population after treatment.
Methods: Of 262 patients consented, 238 were randomized to either standard of care (123) or to receive the iHEART intervention (115). Patients in the intervention group were provided with and trained to use an AliveCor KardiaMobile ECG monitor, and were instructed to take and transmit daily ECG recordings. Data were collected from transmitted ECG recordings and patients' electronic health records.
Results: In a multivariate Cox model, the likelihood of recurrence detection was greater in the intervention group (hazard ratio = 1.56, 95% confidence interval [CI]: 1.06-2.30, P = .024). Hazard ratios did not differ significantly for RFA and DCCV procedures. Recurrence during the first month after ablation strongly predicted later recurrence (hazard ratio = 4.53, 95% CI: 2.05-10.00, P = .0006). Time from detection to treatment was shorter for the control group (hazard ratio = 0.33, 95% CI: 0.57-2.92, P < .0001).
Conclusions: The use of mobile ECG self-recording devices allows for earlier detection of AF/AFL recurrence and may empower patients to engage in shared health decision-making.

RSV vaccine clinical trials reported higher frequencies of atrial fibrillation in intervention groups compared to control. In this large, population-based, propensity-matched study, we found RSV vaccine was not associated with increased risk of new-onset or recurrent atrial fibrillation within 1-42 days compared to influenza or Tdap vaccines.

Aims: Cavotricuspid isthmus (CTI) ablation is the current ablation treatment for typical atrial flutter (AFL). However, post-ablation atrial tachyarrhythmias, mostly in the form of atrial fibrillation (AF), are frequently observed after CTI ablation. We aimed to evaluate the effectiveness and safety of concomitant or isolated pulmonary vein isolation (PVI) in patients with typical AFL scheduled for ablation.

Article Synopsis
- Primary liver cancer, mainly hepatocellular carcinoma (HCC), is a major cause of cancer deaths, and tumor thrombus (TT) in major vessels worsens patient outcomes.
- Four male HCC patients (average age 57) with TT in the inferior vena cava or right atrium underwent surgery to remove the tumors, followed by targeted and immunotherapy.
- All cases show positive outcomes post-treatment, with some patients remaining disease-free for up to 74 months, suggesting that combining surgery with therapy could improve survival rates in advanced HCC patients.
