“…In the present study, contrast echocardiography using Levovist ® showed the LV cavity and blood inflow to the deep intertrabecular recesses so clearly that the extent of the trabecular meshwork was obvious (Fig 2). 14,15 The autopsy of the present case confirmed that the location and size of the prominent trabeculations and deep intertrabecular recesses of the posterior and lateral walls corresponded to the echocardiographic findings. However, it was difficult to detect the trabeculations in the anterior wall by echocardiography, because of the poor resolution of the near field.…”

Noncompaction of the ventricular myocardium (NVM) is a rare disorder of endomyocardial morphogenesis characterized by numerous, prominent trabeculations and deep intertrabecular recesses. It is commonly associated with congenital heart disease, but the isolated form (INVM) is not associated with other structural heart diseases. Clinical reports of INVM have been limited to a few case reports and small series of pediatric patients. INVM is considered to be a form of congenital abnormal endomyocardial morphogenesis caused by abnormal cessation of the embryonic development of the ventricular myocardium; most reported cases have been pediatric patients, and autopsy cases of elderly patients have been quite rare. In the present case, an elderly female had INVM associated with severely disturbed left ventricular (LV) function and an enlarged left ventricle similar to dilated cardiomyopathy. The echocardiogram showed prominent trabeculations and deep intertrabecular recesses of the LV walls, especially in the posterior and apical areas. LV contrast echocardiography revealed markedly protruberant trabeculations, which were also observed with computed tomography. Five years later, the patient died of refractory heart failure and ventricular fibrillation. The autopsy revealed numerous excessively prominent trabeculations in the LV myocardium, with deep intertrabecular recesses containing thrombi. (Circ J 2004; 68: 964 -967)

“…[10][11][12] Reproducibility Ten patients were selected at random for the assessment of intraobserver and interobserver reproducibility of contrast-Vp and 4 types of color-Vp measurements; of these, three had previous myocardial infarction, two had stable angina pectoris, two had idiopathic dilated cardiomyopathy, two had hyperthrophic cardiomyopathy, and one had hypertensive heart disease. To test intraobserver variability, a single observer analyzed the data twice on occasions separated by an interval of 1 month.…”

“…Development of echocardiographic contrast media and related techniques now permits opacification of the LV cavity, using peripheral venous injection of a contrast agent. [10][11][12] We hypothesized that contrast echocardiography might be used to assess propagation of fluid elements derived from LV inflow. The first goal of this study, then, was to quantitate propagation of LV inflow using contrast echocardiography (contrast-Vp).…”

“…[19][20][21][22] Briefly, parasternal long-and short-axis views of the left ventricle (LV) were digitally acquired at baseline. After obtaining the apical 4-chamber view, 2 ml of the intravenous contrast agent (Levovist, Schering AG, Germany; 300 mg/ml) was injected, and CE images were digitally acquired in the apical 4-and 2-chamber views.…”

Background Non-invasive diagnosis and risk stratification of coronary artery disease are important for the selection and optimization of therapeutic interventions in diabetic patients, which may improve survival. The aim of this study was to determine the incremental value of contrast-enhanced dobutamine stress echocardiography (CE-DSE) for risk stratification. Methods and Results CE-DSE was performed in 326 patients with diabetes mellitus (mean age; 66±10 years, 223 men). All patients were followed up for a mean of 29 months (1-61 months). Dobutamine was infused in a standard protocol with an intravenous contrast agent. The primary endpoints for hard cardiac events included cardiac death and nonfatal myocardial infarction. The primary endpoints for total cardiac events included hard cardiac events, unstable angina pectoris, congestive heart failure, and late coronary revascularization (>3 months). Cardiac events occurred in 74 patients. The addition of the CE-DSE results, including abnormal left ventricular end-systolic volume response and left ventricular ejection fraction at peak stress <50%, to the clinical and rest echocardiography model provided incremental information in predicting total cardiac events (increase in chisquare value for the model from 17 to 24, p<0.05) and hard cardiac events (increase in chi-square value for the model from 18 to 24, p<0.05). Conclusions Quantitative assessment of left ventricular function during CE-DSE provides incremental prognostic information in predicting cardiac events in diabetic patients.
