[Cardiovascular disorders in patients infected with 2019 novel coronavirus]. / Atteintes du système cardiovasculaire chez les patients atteints de maladie à coronavirus 19.

The coronavirus disease 2019 (COVID-19) outbreak has become a worldwide public health concern. Cardiovascular complications are relatively frequent, reaching 20% of COVID-19 patients and 43% of COVID-19 patients admitted in Intensive Care Unit. Cardiac injury mechanisms are multiple, including hyperinflammation, pro-coagulant and pro-thrombotic states, sepsis related cardiomyopathy, hypoxia in relation with lung severity, hemodynamic instability, cytokine storm, critically illness, direct myocardial insult by acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and stress cardiomyopathy. The authors report a narrative review about cardio-vascular complications and predictive factors of mortality in patients infected with COVID-19.

[Multicentric experience with the use of Sheathless 6.5 French-size catheter in coronary angioplasty for bifurcation lesions: feasibility and safety]. / Expérience multicentrique de l'utilisation du Sheathless 6.5 French dans l'angioplastie coronaire des lésions de bifurcation : faisabilité et sécurité

BACKGROUND: Transradial intervention of coronary lesion is increasing in frequency and is associated with lower major vascular access site complications. However, the small size of the radial artery is a major limitation of this technique, especially for bifurcation lesions, because 6-French guiding catheters are necessary to optimize the technique. A Sheathless guiding catheter has recently been introduced, optimizing a large lumen with a small size. OBJECTIVES: The aim of this study is to report our preliminary experience performing bifurcated transradial interventions using a 6.5 French Sheathless guide catheter. PATIENTS AND METHODS: From March 2009 to February 2012 in three hospitals, 46 consecutive patients were enrolled in this study who underwent transradial approach (TRA) for percutaneous bifurcation coronary interventions using the 6.5 French Sheathless Eaucath guiding catheter system because of small radial artery caliber. RESULTS: In this study, 46 patients were enrolled with mean age of 72.13 ± 16.41 years. The majority of patients were females with sex-ratio 0.53. Procedural success using the 6.5 French Sheathless guide catheter system was 100 % with no cases requiring conversion to a conventional guide and catheter system. During procedures, adjunctive devices used in this cohort included IVUS (2 patients), 35 bifurcated lesions were treated with a kissing-balloon technique in the group of 46 patients undergoing bifurcation PCIs, one patient required rotational atherectomy, thrombus-aspiration catheters had used in four patients, FFR-guided angiography in four patients. We report one case of chronic total occlusion bifurcated lesion successfully treated using this hydrophilic catheter. There were no radial artery site complications. CONCLUSION: The treatment of coronary bifurcation lesions with 6.5 French Sheathless guiding catheter by transradial approach is feasible and appears safe in this multicenter study.
