Dobutamine stress echocardiography (DSE) is a well-established imaging modality used to screen patients with mild-to-moderate risk for coronary artery disease. In heart transplantation recipients, cardiac allograft vasculopathy (CAV) is a common and lethal complication. The use of DSE to detect CAV showed promising results initially, but later studies showed limitation in its use to detect CAV. It is unclear if this cohort of patients derives benefit from DSE.

Name: Echocardiography (Mount Kisco, N.Y.)
When cardiac stress testing is ordered prior to noncardiac surgery, the optimal test modality is unknown. Therefore, we conducted this study to compare the diagnostic accuracy of dobutamine stress ech...
This study determined the test performance of dobutamine stress echocardiography (DSE) in end-stage liver disease (ESLD).
Echocardiography is regarded as the gold standard for diagnosis of bicuspid aortic valve (BAV), yet diagnostic accuracy has been evaluated previously only in single-center studies. We systematically e...
Primary purpose :To early detect cardiac allograft vasculopathy and to identify patients with high risk of cardiac events, by coupling the analysis of the kinetics of the brain natriuretic...
Patients with chronic kidney disease (CKD) before kidney transplantation require that obstructive coronary artery disease (CAD) is excluded, as cardiovascular complications are the leading...
This study investigates hypothesizes that the combination of dobutamine stress echocardiography with dobutamine stress echocardiography with real time perfusion myocardial contrast echocar...
The goal of this research is to determine the utility of Regadenoson (Lexiscan)for use as an imaging agent with cardiac MR. If found useful, it will help us establish a protocol for regade...
While cardiac resynchronization therapy (CRT) has a well demonstrated therapeutic effect in selected patients with advanced heart failure (HF) on optimized drug therapy, non-responder rate...
Echocardiography applying the Doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return.
Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)
A method of recording heart motion and internal structures by combining ultrasonic imaging with exercise testing (EXERCISE TEST) or pharmacologic stress.
A beta-2 agonist catecholamine that has cardiac stimulant action without evoking vasoconstriction or tachycardia. It is proposed as a cardiotonic after myocardial infarction or open heart surgery.
The pressure within a CARDIAC VENTRICLE. Ventricular pressure waveforms can be measured in the beating heart by catheterization or estimated using imaging techniques (e.g., DOPPLER ECHOCARDIOGRAPHY). The information is useful in evaluating the function of the MYOCARDIUM; CARDIAC VALVES; and PERICARDIUM, particularly with simultaneous measurement of other (e.g., aortic or atrial) pressures.
