BACKGROUND Diastolic suction is a major determinant of early left ventricular filling in animal experiments. However, suction remains incompletely characterized in the clinical setting. METHODS AND RESULTS First, we validated a method for measuring the spatio-temporal distributions of diastolic intraventricular pressure gradients and differences (DIVPDs)(More)
BACKGROUND Ejection intraventricular pressure gradients are caused by the systolic force developed by the left ventricle (LV). By postprocessing color Doppler M-mode (CDMM) images, we can measure noninvasively the ejection intraventricular pressure difference (EIVPD) between the LV apex and the outflow tract. This study was designed to assess the value of(More)
OBJECTIVE To describe postdischarge survival rates and late complications in non-intravenous drug users (non-IVDUs) after treatment of infective endocarditis (IE). PATIENTS AND METHODS This prospective study consists of consecutive cases of IE in non-IVDUs seen between January 1, 1994, and August 31, 2005. Patient treatment (ie, pharmaceutical and/or(More)
BACKGROUND AND AIM OF THE STUDY Because the hemodynamic basis of aortic valve area (AVA) has never been validated in vivo, several alternative indices have been proposed to quantify the severity of aortic stenosis (AS). This study was designed to assess the fluid-dynamics of aortic valve stenosis in order to clarify which index best accounts for disease(More)
OBJECTIVES This study was designed to evaluate the usefulness of transesophogeal echocardiography (TEE) for detecting cardiac damage after blunt chest trauma (BCT). BACKGROUND Multiple methods have been used to detect cardiac damage after a BCT, but none has been demonstrated to be sensitive, specific, and feasible enough. METHODS This multicenter(More)
OBJECTIVE To asses the feasibility, usefulness and clinical rentability of the transesophageal echocardiography (TEE) in the evaluation of patients suffering a severe blunt chest trauma as well as to correlate the TEE findings with those provided by the conventional electrocardiogram (ECG), cardiac isoenzymes assay and transthoracic echocardiography (TTE).(More)
AIMS The aim of this study was to determine the utility of pulsed wave Doppler tissue imaging in the evaluation of regional left ventricular diastolic function in patients with ischaemic heart disease. METHODS AND RESULTS In 30 normal subjects and 43 patients with ischaemic heart disease, Doppler tissue imaging was performed in each of the 16 segments of(More)
OBJECTIVES This study aimed to evaluate the effect of primary angioplasty (PA) over the risk of free wall rupture (FWR) in reperfused acute myocardial infarction (AMI). BACKGROUND It has been suggested that PA reduces the risk of FWR compared with thrombolysis. However, few studies have evaluated this issue, and there are no data demonstrating this(More)
OBJECTIVES This study was designed to assess which hemodynamic index best accounts for clinical severity of aortic stenosis (AS) and to analyze the value of low-dose dobutamine testing. BACKGROUND Pressure gradient and valve area are suboptimal because they depend on flow rate, correlate poorly with symptoms, and provide limited prognostic information.(More)
AIMS To study left atrial dissection, a rare complication of mitral valve replacement. METHODS AND RESULTS From our hospital database of 5497 transoesophageal echocardiograms, we analysed 524 echocardiograms performed on 478 patients with mitral valve prosthesis. We found four patients (0.84%) with left atrial dissection diagnosed by transoesophageal(More)
