AIMS We sought to develop and validate a multiparametric algorithm by applying previously validated criteria to predict cardiac resynchronization therapy (CRT) response in a multicentre study. Thirty per cent of patients treated by CRT fail to respond to the treatment. Although dyssynchrony by echocardiography has been used to improve the selection of(More)
AIMS The choice of resynchronization therapy between with (CRT-D) and without (CRT-P) a defibrillator remains a contentious issue. Cause-of-death analysis among CRT-P, compared with CRT-D, patients could help evaluate the extent to which CRT-P patients would have additionally benefited from a defibrillator in a daily clinical practice.

AIMS Whole body imaging with (18)F-fluorodeoxyglucose positron-emission tomography/computed tomography (FDG PET/CT) has proven useful in various infectious diseases. The purpose of this pilot study was to assess the diagnostic yield of FDG PET/CT in patients with cardiac implantable electronic device (CIED) infection. METHODS AND RESULTS A total of 21(More)
BACKGROUND There are limited data describing sex specificities regarding implantable cardioverter defibrillators (ICDs) in the real-world European setting. METHODS AND RESULTS Using a large multicenter cohort of consecutive patients referred for ICD implantation for primary prevention (2002-2012), in ischemic and nonischemic cardiomyopathy, we examined(More)
Some ligand-receptor couples involve spare receptors, which are apparent when a maximal response is achieved with only a small fraction of the receptor population occupied. This situation favours cross-reactions with low-affinity ligands, which may be detrimental for cell signaling. In the case of the adenosine A2A receptors (A2AR), which have an(More)
Head-up tilt test is useful for exploring neurally mediated syncope. Adenosine is an ATP derivative implicated in cardiovascular disturbances that occur during head-up tilt test. The aim of the present study was to investigate the impact of hyperoxia on adenosine plasma level and on hemodynamic changes induced by head-up tilt testing.Seventeen healthy male(More)
