[Effect of flecainide on longitudinal and transverse conduction velocities in ventricular myocardium. An experimental study].
2007
It is known that the effect of flecainide on longitudinal and transverse ventricular conduction velocities depends on the coupling interval. If this is so, whether the longitudinal or transverse direction is predominantly affected could depend on the magnitude of the coupling interval. In order to investigate this hypothesis, we studied the effect of flecainide, 1 micromol/L, on conduction velocities in excised heart preparations from 11 rabbits using a basal cycle length of 250 ms and inserting two extrastimuli at a decreasing coupling interval. Flecainide significantly reduced both conduction velocities. However, the effect increased as the coupling interval decreased for only the longitu…
The Revolution in Heart Valve Therapy: Focus on Novel Imaging Techniques in Intra-Procedural Guidance
2021
Transcatheter valvular interventions have undergone significant progress over the last years with novel treatment options in even complex valvular conditions. In conjunction with this development, ...

Discrimination of early/intermediate and advanced/complicated coronary plaque types by radiofrequency intravascular ultrasound analysis
2002
Radiofrequency intravascular ultrasound (IVUS-RF) analysis, as an extension of conventional IVUS imaging, may provide more accurate plaque discrimination. Thirty-two autopsy atherosclerotic coronary arteries were investigated. Corresponding sectors in different plaques were matched by histologic and RF analysis. Histologic analysis utilized the American Heart Association plaque classification. The backscattered ultrasound RF signal was analyzed by fast-Fourier transform, providing the underlying frequency components of its power spectrum. The normalized backscattered signal power (in decibels [dB]) for frequencies between 15.3 and 40.3 MHz was then measured for plaque discrimination. Advanc…

276 Evaluation of cardiovascular risk and factors associated to risk under-evaluation in general practice
2011
Correlation between perceived cardiovascular risk (CVR) by physicians and real CVR is poorly known. Moreover, the underlying question of factors associated to risk misevaluation, especially for patients at high CVR and that could benefit of a lipid lowering therapy (LLT), remains unsolved. Objective and methodology This was an on-line non-interventional study conducted on a sample of 619 general practitioners. The aim was to describe the relation between physicians evaluated CVR and calculated CVR according to risk's scales. All consulting patients’ aged50 years old (YO) were included. Physicians had to complete a questionnaire and to assess patient's CVR on a 3 level scale (low, medium, an…

013 Pre-infarction angina and cardiovascular complications in non ST segment elevation myocardial infarction: Data from the RICO survey
2010
BackgroundThe presence of preinfarction angina (PIA) has been shown to confer cardioprotection after ST segment elevation myocardial infarction (MI). However, the impact of PIA in non ST segment elevation (NSTEMI) remains to be determined.Patients and MethodsFrom the obseRvatoire des Infarctus de Côte d’Or (RICO) survey, 1541 consecutive patients admitted in intensive care unit with a first NSTEMI were included in the study. Patients who experienced chest pain 1) and 30-day mortality were collected.ResultsAmong the 1541 patients included in the study, 693 patients presented PIA. Baseline clinical characteristics were similar for the 2 groups. There was no significant difference for the GRAC…
