Disease relevance of Angiocardiography

• Noninvasive examination of these patients shows variation in the presence and magnitude of ST-segment depression, the presence and extent of exercise-induced thallium 201-perfusion defect, and the presence and extent of regional and global left ventricular dysfunction assessed by radionuclide angiocardiography [1].
• Ninety-three percent of survivors had dilated cardiomyopathy consistent with endocardial fibroelastosis by angiocardiography [2].
• To assess the potential improvement in left ventricular ejection fraction after cardioversion of chronic atrial fibrillation to sinus rhythm in idiopathic dilated cardiomyopathy, we studied prospectively 17 patients, aged 58 +/- 6 years, by radionuclide angiocardiography at rest [3].
• The effect of intravenous (IV) nitroglycerin (NTG) on perioperative myocardial ischemia as detected by single pass radionuclide angiocardiography was studied in 20 patients scheduled for elective coronary artery bypass grafting (CABG) [4].
• A series of 72 patients with proved double-outlet right ventricle was studied with reference to the ability of angiocardiography to determine the location of a ventricular septal defect when it was associated with various great-artery relationships [5].

High impact information on Angiocardiography

• Serial assessment of doxorubicin cardiotoxicity with quantitative radionuclide angiocardiography [6].
• The accuracy of rest and exercise radionuclide angiocardiography (RNA) and exercise treadmill testing (ETT) for diagnosis of three-vessel or left main coronary artery disease (extensive CAD) was determined in 544 patients [7].
• The use of axial angiocardiography facilitates detection and localization of the ventricular septal defect [8].
• Left ventricular end-diastolic volume and ejection fraction assessed by radionuclide angiocardiography were not significantly changed at rest or during exercise after hydralazine [9].
• Assessment of cardiac performance with quantitative radionuclide angiocardiography. Effects of oral propranolol on global and regional left ventricular function in coronary artery disease [10].

Chemical compound and disease context of Angiocardiography

• Twenty patients under the age of 2 years with suspected congenital heart disease received alternately Renografin 76 and metrizamide for angiocardiography [11].

Biological context of Angiocardiography

• We measured cardiac performance sequentially, using quantitative radionuclide angiocardiography to estimate left ventricular ejection fraction in 55 patients receiving doxorubicin for treatment of cancer [6].
• In the context of a multicentre study on the use of technetium 99m hexakis-2-methoxyisobutylisonitrile (99mTc-Sestamibi), we evaluated the accuracy of the ventricular function assessed at rest by means of first-pass radionuclide angiocardiography acquired during the injection of the tracer for myocardial perfusion scintigraphy [12].
• Hemodynamic effects of nebivolol in men: comparison of radionuclide angiocardiography with systolic time intervals [13].
• In comparison to angiocardiography, the measured volumes were 1.1 +/- 6.9 ml (19.5 +/- 34.1%) or 6.3 +/- 9.4 ml (42.5 +/- 33.6%) smaller during systole or diastole, respectively [14].

Anatomical context of Angiocardiography

• We evaluated the volumetric responses of the right and left ventricles to upright exercise using two noninvasive methods, first-pass radionuclide angiocardiography and the CO2 rebreathing technique, in nine normal subjects [15].
• Effects in angiocardiography from injections into the right atrium of rabbit hearts of a new, non-ionic contrast medium (Amipaque) were studied and were compared with the effects from injections of an ionic medium (Isopaque Coronar) at a dose of 3 ml/kg rabbit and concentration of 370 mg I/ml [16].
• The scope of diagnosing mitral valve prolapse (MVP) has been enlarged by the earlier reported real-time B-scan criteria of small or "localised MVP". This form is believed to be the precursor of the overt MVP which is then readily diagnosed by angiocardiography and 1- and 2-dimensional echocardiography (1- and 2-dE) [17].
• Two standard procedures are routinely used: (1) myocardial perfusion scintigraphy, eg, with thallium 201; and (2) radionuclide angiocardiography by using technetium 99m-labeled red blood cells [18].
• CONCLUSION: Even in this young age group, MR imaging offers a good alternative to angiocardiography for the pre-operative evaluation of the right ventricular outflow tract, the main pulmonary artery and the proximal right and left pulmonary arteries, before definitive surgical correction of tetralogy of Fallot and pulmonary atresia with VSD [19].

Associations of Angiocardiography with chemical compounds

• The results with first-pass radionuclide angiocardiography (RNA) using gold-195 m at rest were reproducible and agreed closely with the results obtained using technetium-99 m equilibrium radionuclide angiocardiography (r = 0.93) [20].
• A new osmium-191 leads to iridium-191m generator suitable for first-pass radionuclide angiocardiography has been developed [21].
• We tested the relationship of nitrate-induced changes in 99mTc-sestamibi perfusion tomography and first-pass radionuclide angiocardiography (FPRNA) with postrevascularization functional recovery of asynergic territories [22].
• The aims of this study were: (1) to test whether first-pass radionuclide angiocardiography (FPRNA) adds useful information to perfusion scintigraphy; and (2) to assess the relative accuracy of perfusion and functional imaging in combination with dipyridamole for the evaluation of CAD [23].
• The results were compared with first-pass studies performed using reference tracers sodium pertechnetate Tc 99m or technetium 99m diethylene triamine penta-acetic acid or with gated radionuclide angiocardiography [12].
