Is the duration of dual antiplatelet therapy (DAPT) excessive in post-angioplasty in chronic coronary syndrome? Data from the France-PCI registry (2014-2019).

Background: while the duration of dual antiplatelet therapy (DAPT) following coronary angioplasty for chronic coronary syndrome (CCS) recommended by the European Society of Cardiology has decreased over the last decade, little is known about the adherence to those guidelines in clinical practice in France. Aim: To analyze the real duration of DAPT post coronary angioplasty in CCS, as well as the factors affecting this duration. Methods: Between 2014 and 2019, 8.836 percutaneous coronary interventions for CCS from the France-PCI registry were evaluated, with 1 year follow up, after exclusion of patients receiving oral anticoagulants, procedures performed within one year of an acute coronary syndrome, and repeat angioplasty. Results: Post-percutaneous coronary intervention (PCI) DAPT duration was > 12 months for 53.1% of patients treated for CCS; 30.5% had a DAPT between 7 and 12 months, and 16.4% a DAPT ≤ 6 months. Patients with L-DAPT (>12 months) were at higher ischemic risk [25.0% of DAPT score ≥2 vs. 18.8% DAPT score ≥2 in S&I-DAPT group (≤12 months)]. The most commonly used P2Y12 inhibitor was clopidogrel (82.2%). The prescription of ticagrelor increased over the period. Conclusions: post-PCI DAPT duration in CCS was higher than international recommendations in the France PCI registry between 2014 and 2019. More than half of the angioplasty performed for CCS are followed by a DAPT > 12 months. Ischemic risk assessment influences the duration of DAPT. This risk is probably overestimated nowadays, leading to a prolongation of DAPT beyond the recommended durations, thus increasing the bleeding risk.

[Incidence and evolution of thrombotic images within the internal jugular vein following Swan-Ganz catheter insertion in cardiac surgery]. / Incidence et évolution des images thrombotiques dans la veine jugulaire interne après cathétérisme de Swan-Ganz en chirurgie cardiaque.

OBJECTIVES: Insertion of Swan-Ganz catheter for a few days may be necessary in cardiac surgery. This study was aimed at determining the incidence and the evolution of thrombotic images within the internal jugular vein as well as assessing their association with the presence of a prolonged fever at postoperative day 7 in the lack of any documented infection. MATERIAL AND METHODS: All the patients undergoing cardiac surgery had a two-dimensional ultrasonography of internal jugular veins preoperatively, at discharge (day 7) and at postoperative day 90 if thrombotic images were seen at day 7. RESULTS: Sleeve-like and compact thrombotic images have been observed in site of venipuncture in 52 patients (70.3%). None had any residual thrombotic image 90 days after the operation. No clinical thromboembolic migration has been observed. There was no statistical association between the presence of a thrombotic image at the ultrasonography and the duration of catheterization. Moreover, there was no association between the anticoagulation before, during and after the surgery and the presence of a thrombotic image. We found a non-significant association between fever at day 7 and the presence of a thrombotic image within the internal jugular vein. CONCLUSION: Thrombotic images in the internal jugular vein after catheterization are frequent and disappear at day 90. The limited sample size of this study does not provide strong evidence of the role of jugular thrombi in the prolongation of fever after cardiac surgery.

[Night cardiac rhythm and conduction disturbances revealing obstructive sleep apnoea syndrome]. / Trouble de conduction atrioventriculaire paroxystique nocturne révélant un syndrome d'apnée du sommeil.

There is a strong prevalence of sleep apnoea syndrome in general population. Cardiac arrhythmia and conduction disturbances during sleep may complicate this syndrome. We report the case of a 73-year-old patient to whom the sleep apnoea syndrome was diagnosed after varied heart blocks during the sleep. A treatment by continuous positive airway pressure (CPAP) permitted to correct these conduction disturbances and to avoid pacemaker implantation.

We report a 29-year-old woman with an acute myocarditis documented by MRI as presenting manifestation of a pheochromocytoma, and we review the literature.
