,Excited Nuclear States for Cd-99?(Cadmium),al positive d./d.) and diastolic (maximal negative d./d.) function [1]. However, these parameters require high fidelity pressure recordings with the accompanying risk of an invasive procedure. A noninvasive method for assessment of maximal d./d. and maximal negative d./d. would, therefore, be of gre

Excited Nuclear States for Cd-105 (Cadmium),entricular structure and function. To characterize left ventricular systolic performance two-dimensional echocardiography is used to determine ejection fraction and Doppler echocardiography is used to derive systolic ejection indices [1,2]. In addition, techniques have been developed to noninvasivel

Excited Nuclear States for Cd-102 (Cadmium),wo-dimensional and Doppler echocardiography have been used as diagnostic tools for assessment of various parameters both prior to as well as during and after the procedure. Echocardiography renders information with respect to the presence of thrombotic lesions and morphological features of the valve

Excited Nuclear States for Cd-111 (Cadmium),trophy. Abnormalities in the transmitral flow velocity curve have been found in symmetrical left ventricular hypertrophy due to pressure overload, such as arterial hypertension and aortic stenosis [1], as well as in hypertrophic cardiomyopathy [2–4], a disease characterized by an asymmetrical ventri

Excited Nuclear States for Cd-111 (Cadmium),pact on long term survival as a result of two factors: the introduction routine surveillance endomyocardial biopsy for monitoring cardiac rejection and its reversal with medication, and the use of Cyclosporine for maintenance immunosuppression. The effect of improved monitoring with cardiac biopsy w

In contrast, the search of a method for reliable quantification of valvular regurgitation is still ongoing. In recent years, a bulk of publications testify the efforts for definition and validation of a satisfactory

Poor signal to noise ratio may obscure a lot of diagnostic flow information. Experimental studies [1–3] have confirmed that flow detection by color Doppler may be con

It has been used to detect valvular regurgitation, identify and distinguish atrial and ventricular septal defects, assess complex congenital heart disease, measure cardiac output, and is used during cardiac surgery to evaluate repair of cardiac valves or congenital abnormalities [2–4].
