Comparative Study[Vascular approaches and closure devices for percutaneous coronary intervention].
The choice of a transradial or transfemoral approach remains a pivotal decision in percutaneous coronary angioplasty. We discuss here the varying criteria leading to a rational choice in the arterial access choice. Since the emergent transradial approach in France has led to a dramatic reduction in local vascular complications, we also discuss the remaining place of femoral approach and the usefulness of femoral percutaneous closure devices.

Case Reports[Left ventricular assist devices in the catheterisation laboratory].
Mechanical cardiac support represents a large spectrum of devices. The duration of assistance may vary from a few hours in the cath lab to several weeks. The goals for a temporary support by percutaneus assistance are: improve end-organ perfusion; decrease pulmonary capillary wedge pressure; decrease myocardial oxygen consumption. The potential indications are: acute left ventricular dysfunction; "bridge to recovery": acute myocarditis, acute myocardial infarction, valve disease bridge to surgery; "bridge to implantable LVAD"; "bridge to transplant"; high risk PCI and surgery.

Comparative Study[Platelet responsiveness to clopidogrel in patients with coronary syndrome. Comparison of platelet aggregation induced by ADP and flow cytometric analysis of intraplatelet VASP phosphorylation].
Although antiplatelet therapy with ASA-clopidogrel reduces the risk of cardiovascular episodes after PCI, a substantial number of events occur during follow-up. Sustained platelet reactivity under dual antiplatelet therapy was recently associated with increased risk of recurrent atherothrombotic events after PCI. Whereas it appears significant to determine clopidogrel responsiveness, the accurate platelet function assay is still under investigation. ⋯ During coronary syndrome, impaired platelet responsiveness to clopidogrel was observed in a large proportion of patients whatever the platelet function assay used. VASP analysis was found insensitive to GPIIbIIIa or aspirin administration. Possible mechanisms linking clopidogrel "resistance" measured by VASP assay and enhanced thrombogenicity remain to be characterized. Indeed, clopidogrel "resistance" defined by VASP analysis was not associated with higher platelet aggregation.

Multicenter Study[Influence of percutaneous coronary intervention in non ST-elevation acute coronary syndromes on prescription of secondary prevention medications. Data from the S-Témoin Registry].
The interaction between the use of percutaneous coronary intervention (PCI) for non-ST-elevation acute coronary syndromes and the use of secondary prevention medications was analysed in the French S-Témoin Registry. ⋯ Patients not treated with PCI are less likely to receive appropriate secondary prevention medications after non ST-elevation acute coronary syndromes. Specific efforts should be directed towards these patients, in particular as regards the prescription of dual antiplatelet therapy.

Review[Pacemakers and defibrillators: what should we know about home monitoring?].
Cardiac stimulators and defibrillators dispose of diagnostic capabilities. Home monitoring permits to have information about the cardiac rhythm of the patient and about the function of the pacemaker or the defibrillator. Technical aspects, safety and legal issues of home monitoring are discussed in this article.
