Randomized studies have reported low rates of atrial fibrillation (AF) after patent foramen ovale (PFO) closure (6%) but have relied on patient-reported symptomatic episodes, so the true incidence and timing of AF after PFO closure remain unknown.The aim of this study was to prospectively determine the incidence, timing, and determinants of supraventricular arrhythmia following PFO closure on the basis of loop recorder monitoring.Cardiac monitoring was proposed to all patients after PFO closure from June 2018 to October 2021 at a single center by means of implantable loop recorder monitoring in patients considered at higher risk for AF (age ≥ 55 years, associated cardiovascular risk factors, prior palpitations, or documented supraventricular ectopic activity) or 4-week external loop recorder monitoring in other patients. The primary endpoint was the incidence of AF, atrial flutter, or supraventricular tachycardia lasting30 seconds within 28 days of the procedure. Determinants of the primary endpoint were assessed using a stepwise logistic regression model.A total of 225 patients were included. The primary endpoint occurred in 47 patients (20.9%), including 13 (9.9%) and 24 (28.9%) among patients monitored with external loop recorders and implantable loop recorders, respectively. Overall, the median delay from procedure to arrhythmia was 14.0 days (IQR: 6.5-19.0 days), and one-half of these patients reported symptomatic episodes. Determinants of the primary endpoint were older age (adjusted OR: 1.67 per 10-year increase; 95% CI: 1.18-2.36), device left disc diameter ≥25 mm (adjusted OR: 2.67; 95% CI: 1.19-5.98) and male sex (adjusted OR: 4.78; 95% CI: 1.96-11.66).Using loop recorder monitoring for ≥28 days, supraventricular arrhythmia was diagnosed in 1 in 5 patients, with a median delay of 14 days, suggesting that this postprocedural event has so far been underestimated.

We read with great interest the pooled analysis by Garcia-Garcia et al. ([1][1]) on the impact of periprocedural biomarker elevation on mortality following elective percutaneous coronary intervention. Data were obtained from 5 randomized controlled trials and 1 registry (13,452 patients). Creatine

Decisions on antiplatelet therapy may appear increasingly complex, and vary according to the clinical situation. Concerning P2Y12 antagonists, drug choice, administration route, timing of administration, and duration of therapy need to be factored into the decision making. There are less evidence

ObjectivesThis study sought to assess the consequences of switching prasugrel to clopidogrel on platelet inhibition and clinical outcomes after an acute coronary syndrome (ACS).BackgroundMany ACS patients are switched from prasugrel to clopidogrel within the recommended 1-year duration of treatment.MethodsPlatelet reactivity was measured with the VerifyNow P2Y12 assay (Accumetrics, San Diego, California) in 300 ACS patients treated for 15 days with prasugrel 10 mg. Patients displaying low on-treatment platelet reactivity (LPR) and/or at high risk of bleeding were switched to clopidogrel 75 mg and tested again 15 days later. The rate of patients with high on-treatment platelet reactivity (HPR), P2Y12 reaction units (PRU) >208, and LPR (PRU

Objectives: This study sought to determine whether the pharmacokinetic (PK) and pharmacodynamic (PD) responses to high or standard clopidogrel loading doses (LDs) differ according to CYP2C19*2 alle...
