Diagnostic studies Flashcards
Name the Advantages of transthoracic echocardiography.
Advantages:
Accurate diagnosis of structural heart disease
Quantitation of left ventricular size and function, pulmonary pressures, valvular disease and intracardiac shunts.
Widely available, portable, fast.
Name the of Advantages of transesophageal echocardiography.
High-quality images, especially posterior cardiac structures.
Most accurate test for evaluation of endocarditis, prosthetic valves, and left atrial thrombus.
Name the limitations of transthoracic echocardiography.
Operator dependent data acquisition.
Interpretation requires expertise.
Variability in instrumentation.
Image quality limits diagnosis in some patients.
Name the Limitations of transesophageal echocardiography
Requires esophageal intubation with conscious sedation.
Name the advantages And limitations of radionucleotide angiography or MUGA.
Advantages:
Quantitative ejection fraction measurements.
Limitations:
Less accurate with atrial fibrillation
Radiation exposure
No data on other cardiac structures.
Name the advantages of cardiac catheterization
Direct measurement of intracardiac pressures.
Contrast angiography provides visualization of complex cardiac anatomy.
Allows intervention for structural heart disease.
Name the limitations of cardiac catheterization.
Invasive
Radiation exposure
Images are not tomographic
IV contrast exposure.
Name the major indications for cardiac magnetic resonance imaging.
Congenital heart disease
Aortic disease
Myocardial viability
Infiltrative myocarditis, hypertrophic cardiomyopathy or other myocardial diseases
Right ventricular cardiomyopathy
Quantitation of left ventricular mass and function.
Name the advantages of CMR imaging.
High-resolution tomographic data and bloodflow imaging.
Quantitative right ventricular volumes and ejection fraction.
No ionizing radiation Or contrast.
Enables 3-D reconstruction of Aortic and coronary anatomy.
Name the limitations of CMR imaging.
Limited availability and expertise.
Some patients experience claustrophobia.
May not be appropriate for patients with implanted devices.
Name indications for cardiac CT.
Aortic disease
Coronary disease
Cardiac masses
Pericardial disease
What are the advantages of cardiac CT?
High-resolution tomographic images.
Enables 3-D reconstruction Of aortic And coronary anatomy.
Name the limitations of cardiac CT.
Contrast injection
Radiation exposure
Limited expertise for interpretation.
