Full textComplications of atherosclerosis are responsible for the two leading causes of death worldwide. These two causes alone account for more than 20% of deaths worldwide. They concern in France and around the world, in particular the industrialized countries, a growing population. The scanner is an imaging modalities allowing the diagnosis of cardiac disease, however its use is now limited to the detection of stenosis significantly obliterating the vessel lumen. In this thesis, the objective was to , on the one hand, exploit the potential of dual energy scanner developed by Siemens Healthcare for a better characterization of the atherosclerotic plaque by developing an image processing program in postreconstruction, and on the other hand, the implementation of a numerical deformation code developed in the laboratory for analysis of the biomechanical impact of atherosclerotic plaque through obtaining various parameters of left ventricular function both global and regional (global parameters: global ejection fraction, sphericity index; regional parameters : lagrangian strain, strain rate, natural movement, segmental ejection fraction). Finally, the main goal is to make available to the clinician a diagnostic tool complementary to current techniques

Full textMechanical ventilation induces cyclic changes in left ventricular stroke volume. These changes are related to the expiratory decrease in left ventricular preload following the inspiratory decrease in right ventricular filling and ejection. The magnitude of respiratory changes in left ventricular stroke volume reflects the sensitivity of the heart to the mechanical insufflation-induced changes in ventricular preload. In clinical practice, respiratory changes in left ventricular stroke volume can be assessed by analysis of the arterial pressure wave form (arterial catheter) or of aortic blood velocity (Doppler). In ventilated patients with acute lung injury, the respiratory changes in arterial pulse pressure predict the hemodynamic effects of positive end-expiratory pressure (Study # 1). In septic patients with acute circulatory failure, the respiratory changes in arterial pulse pressure (Study # 2) and in aortic blood velocity (Study # 3) predict the hemodynamic effects of volume expansion. These dynamic parameters are better predictors of fluid responsiveness than static indicators of right and left ventricular preload (Study # 4)

Full textAortic stenosis is the most common valvular heart disease in developed countries. Approximately, 5 to 10 % of patients with severe aortic stenosis have a low cardiac output with impaired left ventricular ejection fraction (LVEF). The presence of a low cardiac output can distort the assessment of the severity of the aortic stenosis and thus lead to non-adequate therapeutic decision. Two main challenges are posed by these patients. The first is to differentiate a truly severe AS from a pseudo-severe AS, i.e. a failing left ventricle unable to fully open valve slightly or moderately stenotic. This distinction is crucial because the aortic valve replacement will be beneficial only in the case of true-severe AS. The second challenge is to accurately quantify myocardial damage. To this effect, the contractile reserve is important to assess because patients who do not have contractile reserve have a high risk of operative mortality following AVR. Unfortunately, traditional parameters derived from rest or stress echocardiography that are used to assess the severity of AS and myocardial dysfunction are not adequate in low flow state. Therefore, quantification of the disease severity and the ensuing therapeutic management may not be appropriate in a large proportion of these patients. The main objective of this project is to determine the usefulness of left ventricular longitudinal deformation measured at rest and during stress echocardiography with dobutamine for risk stratification and its impact on prognosis and management of patients with low-gradient aortic stenosis with impaired LVEF. Our hypothesis is as follows: The left ventricular global longitudinal strain is superior to the LVEF to predict mortality in patients having LF-LG AS with low EF included in the TOPAS study.

Full textMitral regurgitation is the most frequent valvular disease in western countries. Organic mitral regurgitation is a progressive disease associated with worse prognosis and reduced survival. Surgical intervention (mitral valve repair or replacement) and transcatheter mitral valve procedure are the only available therapies for severe mitral regurgitation. However, the optimal timing of mitral valve surgery in asymptomatic patients with severe mitral regurgitation remains controversial. Some studies concluded that, with a rigorous follow-up and a prompt surgery when the surgical criteria described in the guidelines occur, patients with a severe mitral regurgitation had a similar survival as the rest of the population. Several studies suggested that, in patients with severe mitral regurgitation, an early surgery after the diagnosis improved the prognosis compared to a “watchful waiting” strategy. There is probably no universal strategy for every patient in every hospital. We need to improve individualized risk stratification in patients with organic mitral regurgitation, so we can improve the follow-up of the patients and the selection of the optimal timing of the surgery. There is an important proportion of the patients who will never need to be operated because they will never meet surgical criteria and never develop symptoms. However, we are currently unable to determine which patients will develop left ventricular systolic in the postoperative period, despite the fact that they have no surgical criteria in the pre-operative period. The actual surgery criteria in the guidelines are: the occurrence of symptoms, a left ventricular systolic dysfunction (established by a left ventricular ejection fraction <60% or a left ventricular end-systolic diameter >40mm), the occurrence of a new onset of atrial fibrillation and the occurrence of a new onset of pulmonary hypertension. The objective of this master project was to identify the echocardiographic factors that improve risk stratification in patient with an asymptomatic mitral regurgitation. Our main hypothesis was that the forward left ventricular ejection fraction, calculated by Dumesnil method, is more sensitive than the total left ventricular ejection fraction to detect left myocardial dysfunction and predict event (mitral surgery or death) in patients with an organic mitral regurgitation without surgical criteria.
