Limitations of radionuclide ventriculography in the non-invasive diagnosis of coronary artery disease. A correlation with right heart haemodynamic values during exercise.
A consecutive series of 56 patients with chest pain but no evidence of previous myocardial infarction was prospectively studied by radionuclide ventriculography to determine the value of global and regional radionuclide indices in detecting coronary artery disease. The results were correlated with the clinical judgment of chest pain, the results of the exercise electrocardiogram, and the right ...
متن کاملRight ventricular function at rest and during exercise in chronic obstructive pulmonary disease. Comparison of two radionuclide techniques.
Right ventricular function was assessed in 24 patients with COPD, at rest and during submaximal exercise, using both technetium-99m (99mTc) blood-pool and krypton-81m (81mKr) equilibrium ventriculography. Technetium-99m right ventricular ejection fraction (RVEF) at rest was lower than 81mKr RVEF (0.39 +/- 0.12 and 0.54 +/- 0.08, respectively; p < 0.001). During submaximal exercise, there was no...
متن کاملHigh-grade atrioventricular block caused by his-purkinje injury during contrast left ventriculography.
A68-year-old woman with exertional chest discomfort was referred for cardiac catheterization. Her medications did not include atrioventricular (AV) nodal blocking agents, and she had no prior history of dizziness or syncope. Her admission ECG was normal, including a normal axis, PR interval, and QRS morphology and duration (Figure 1). Right heart catheterization and coronary angiography demonst...
متن کاملAssessment of left ventricular performance during percutaneous transluminal coronary angioplasty: a study by intravenous digital subtraction ventriculography.
Left ventricular performance during percutaneous transluminal coronary angioplasty was assessed in 52 patients by intravenous digital subtraction ventriculography. After injection of contrast into the right atrium ventriculograms were obtained before and during balloon inflation. In 37 patients they were also obtained after the procedure. A 12 lead electrocardiogram was monitored throughout. Du...
متن کاملMR ventriculography for the study of CSF flow.
BACKGROUND AND PURPOSE Various MR techniques have been used to assess CSF flow and to image the subarachnoid spaces and ventricles. Anecdotal reports describe the use of intrathecal and intraventricular gadolinium-based contrast agents in humans and animals. We sought to determine the clinical usefulness of gadolinium-enhanced MR ventriculography for assessing CSF flow in patients with various ...
