..To determine whether persistent versus early or delayed T wave normalisation of negative T waves after acute myocardial infarction is determined by the myocardial state, the treatment strategy, or both...

..Acute mitral regurgitation may cause pulmonary edema, but the pathogenetic role of chronic ischemic mitral regurgitation, a dynamic condition, has not yet been characterized...

..Mitral valve repair--undersized annuloplasty--can be useful but the indications are still controversial. Percutaneous annul loplasty is feasible. The first implantation in the world of one of the devices has been performed in CHU Liège...

..This study sought to evaluate the safety and efficacy of arbutamine echocardiography in identifying contractile reserve and predicting functional improvement early after acute myocardial infarction (AMI)...

..Some patients are good candidates for cardiac resynchronization therapy that may reduce the amount of regurgitation. New therapeutic targets are under investigation...

..However, they are not always consistent due to the lack of randomized data and it appears that, frequently, there is a gap between the existing guidelines and their effective application...

..However, the determinants of exercise PHT have not been evaluated. The aim of this study was to identify the echocardiographic predictors of exercise PHT and the impact on symptoms...

..Significant exercise-induced increases in MR unmask patients at high risk of poor outcome...

..Further studies are required to determine whether surgery should be recommended in the presence of an abnormal exercise echocardiogram in severe asymptomatic aortic stenosis...

..Management is not strictly codified due to the small number of observed cases. We report the case of a 78 year-old man in whom the diagnosis has been performed lately during an echocardiography...

..We review the criteria for the use of anti-vitamin K as well as its daily management in patients with atrial fibrillation...

..Thanks to the improvement of the Doppler signal quality, quantification of the regurgitant volume variations can be obtained in a reproducible manner at rest and during effort by applying the "PISA" method...

..This study assesses the Doppler echocardiographic determinants of a positive exercise test in a cohort of asymptomatic patients with AS...

....

..In this setting, the extent of left ventricular (LV) dyssynchrony contributes to exercise symptoms. Whether exercise-induced changes in LV dyssynchrony might be a trigger of BNP release has never been investigated...

....

..The present study sought to assess the effect of global left ventricular (LV) afterload on LV myocardial systolic function in patients with aortic stenosis (AS) and preserved LV ejection fraction...

..It is crucial to provide standards that aim at establishing a baseline list of measurements to be performed when assessing regurgitation...

..The present document aims to provide standards for the assessment of mitral and tricuspid regurgitation...

..We sought to evaluate prognostic markers of clinical outcome in asymptomatic patients with moderate to severe aortic stenosis (AS)...

..Indications for implantable cardiac defibrillator are still debated. A global and multidisciplinary approach of the patient and of his family is mandatory...

..In patients with asymptomatic valvular aortic stenosis, exercise testing may help to stratify the clinical risk. However, data are limited, and the role of quantitative exercise Doppler echocardiography has never been investigated...

..The aim of this study was to define normal regional strain rate and strain values for both radial and deformation longitudinal myocardial deformation during supine bicycle...

..Enrolment began in November 2006 and is expected to end by early 2008...

..The impact of dynamic MR on long-term mortality, hospital admission for heart failure, and major adverse cardiac events has never been investigated...

..Pulmonary hypertension, a marker of poor prognosis in heart failure, may develop or increase during exercise. We sought to examine the determinants of pulmonary hypertension at rest and during exercise in heart failure patients...

..This operation allows to fix the aortic root pathology, whilst preserving the native aortic valve. The technical aspects, surgical indications, and potential benefits of this operation are reviewed...

....

..However, myocarditis could not be completely ruled out...

....

..As the reduction in left ventricular systolic pressure contributes to the decrease in regurgitant volume, the preoperative quantitative assessment of MR should best be performed by measurement of the ERO...

..The pathogenesis and identification of the underlying disease process are essential for optimal medical approach. The aetiology is multiple...

..We then present factors influencing prescription or non prescription of heart failure drugs and emphasize the importance of a team management programme and patients pathways...

..Alternative methods for assessing ULF spectral power using data from commercial Holter analysers were studied. Different heuristics for ULF calculation were compared with standard research software-based determination of ULF...

..The implicated genes encode cardiac ion channel subunits or proteins involved in modulating ionic currents. The diagnosis of LQTS can be complex in borderline cases. Etiology, pathogenesis, diagnosis and treatment are discussed...

..Active LA dysfunction is related to the severity of AS and late left ventricular diastolic function...

..This review will show how exercise-induced changes in dyssynchrony and severity of mitral regurgitation and the role of preserved contractile reserve may help to better identify potential responders...

..For all forms of stress both pSR and pVel increased linearly, whereas pepsilon response was biphasic as a result of the reduced filling at higher HRs...

..For most interventions, it is recommended to continue antiplatelet therapy. It is particularly important in patients who benefited from drug-eluting stents where the thrombotic risk is major...

..QT dispersion changes during the test are the most accurate parameter...

..To assess polymorphonuclear neutrophils activation after stenting in acute coronary syndromes studied by myeloperoxydase, lactoferrin and elastase release in this clinical setting...

....

..In conclusion, in stable coronary artery disease, inflammation is associated with long-term adverse events, but the magnitude of the inflammatory reaction after PCI appears more predictive than the baseline value...

..Treatment with corticosteroids exacerbates and extends the course of recurrent pericarditis and attenuates the efficacy of colchicine...

..The most important parameter for prognosis and requiring aggressive management is a structural heart disease. Patient without cardiopathy presenting multiple episodes may be candidate for tilt testing and loop EKG recorder...
