Background: Conventional echocardiography is not a reliable method for characterizing tissue patterns of intracardiac masses.

Aims: To assess the ability of contrast echocardiography to characterize intracardiac masses.

Methods: Thirty-one consecutive patients with an intracardiac mass were included in this prospective study.

The aim of this study was to characterize left ventricular (LV) systolic function using 2-dimensional strain in Tako-Tsubo cardiomyopathy (TTC). Forty-two women were prospectively studied using 2-dimensional speckle-tracking echocardiography, divided into 3 groups: 14 patients with TTC (group 1), 14 patients with coronary artery disease (group 2), and 14 healthy patients (group 3). In patients with TTC, mean values of systolic peak velocity, strain, and strain rate were significantly lower than those in group 3 (p <0.

The diagnosis of pulmonary embolism (PE) is difficult, despite validated diagnostic models. We sought to determine the value of a portable ultrasound device for triage of patients with suspected PE referred to the emergency department, using simplified echo criteria. We prospectively studied 103 consecutive patients with suspected PE, referred to our emergency department.

The management of patients with end-stage heart failure is difficult and may require the monitoring of intracardiac pressures. The aim of this prospective study was to assess the reliability of echocardiography in patients with end-stage HF. Twenty consecutive patients presenting with severe left ventricular dysfunction in end-stage heart failure were prospectively studied.

Fifty consecutive patients referred to a coronary care unit for acute anterior myocardial infarction with ST-segment elevation underwent coronary arteriography, left ventricular (LV) angiography, and revascularization. Transthoracic echocardiography was systematically performed using fundamental imaging, second harmonic imaging, and contrast agents to assess the LV chamber. Six patients (12%) presented with a confirmed LV mural thrombus.

Background And Objective: Carcinoid syndrome may involve right carcinoid heart disease (CHD), secondary to the release of vasoactive substances. Left CHD is rare, as the inactivation of serotonin by the lung protects the left heart. We attempted to evaluate the prevalence of CHD and patent foramen ovale (PFO) with serial contrast transthoracic echocardiographic studies and to determine the markers of right and left CHD progression.

Background: The quantification of intracardiac shunt (ICS) with echocardiographic pulsed-wave Doppler (PWD) method using pulmonary-to-systemic flow ratio (QP/QS ratio) remains difficult and may induce false quantification of pulmonary output. We sought to validate the recent echocardiographic automated cardiac output measurement (ACM) for the calculation of pulmonary output and the quantification of ICS in adults.

Methods: One hundred and twenty consecutive patients were divided in 1) 40 patients who underwent echocardiographic and invasive explorations (group I) with groups IA (quantification of ICS using ACM, PWD and invasive oximetric methods in 20 patients) and IB (calculation of pulmonary output with ACM, PWD and thermodilution methods in 20 patients); 2) 80 patients underwent calculation of aortic and pulmonary outputs using echocardiographic ACM and PWD methods (group II).

Assessment of left ventricular (LV) diastolic filling pressure provides important information on the hemodynamic status in the general population. The aim of our study was to investigate the reliability of tissue Doppler imaging (TDI) in estimating left ventricular filling pressure in patients with coronary artery disease (CAD). We prospectively studied 32 consecutive CAD-patients, mean age 64 +/- 12 years, in sinus rhythm.
