1. Intracoronary Hydatid Cyst Resulted in Coronary Artery Disease in a Young Patient
Abstract Among all cystic echinococcosis cases, only 0.5%-2% exhibit a cardiac involvement. Only 10% of these become symptomatic. Considering the long time interval between the start of infestation and symptoms to occur, it is hard to diagnose cystic echinococcosis. When detected, even if it is asymptomatic, intramyocardial hydatid cyst requires surgical int

2. Left ventricular function and coronary artery evaluation in the late follow-up after Jatene´s operation for transposition of the great arteries / "Estudo da função ventricular esquerda e da circulação coronária em pacientes com transposição das grandes artérias corrigida pela técnica de Jatene: resultados tardios"
Vinte e cinco pacientes com tempo de evolução pós-operatório médio de 10,6 ± 5,4 anos após a Operação de Jatene foram submetidos à avaliação da função ventricular esquerda pela ecocardiografia em repouso e durante o estresse farmacológico e à avaliação da circulação coronária pela cinecoronariografia e ultra-som intracoronário. O grupo

3. "Definição de conduta na investigação de doença coronária obstrutiva utilizando teoria de conjuntos fuzzy aplicada a dados clínico-epidemiológicos, ergométricos e cintilográficos" / Establishment of diagnostic procedures for coronary artery disease based on fuzzy set theory applied to clinical epidemiological data and treadmill electrocardiography and myocardial perfusion scintigraphy results.
Coronary artery disease (CAD) is a worldwide leading cause of death. Early detection is important to prevent such sort of outcome. The gold standard method for evaluating critical partial occlusions is coronary arteriography, a catheterization technique which is invasive, time consuming, and costly. There are noninvasive approaches for early detection of CAD

4. "Contribuição ao estudo da estimulação ventricular e do atrio ventricular universal em portadores da miocardiopatia chagásica: avaliação clínica e hemodinâmica em repuso e exercício" / Clinical and Haemodynamic Evaluation of Ventricular versus Atrioventricular Pacing in Patients with Chagas Cardiomyopathy at Rest and during Exercise
Foram estudados dez pacientes portadores de cardiopatia chagásica, com bloqueio avançado da condução atrioventricular, submetidos a implante de marcapasso atrioventricular universal. Os pacientes foram selecionados a partir do estudo clínico, que identificou os portadores de insuficiência cardíaca congestiva de grau leve (classes funcionais I e II); r

5. Comparative recognition of left ventricular thrombi by echocardiography and cineangiography.
Studies performed in 47 patients, 11 of whom underwent surgery for aneurysmectomy and 36 of whom underwent cardiac transplantation, were reviewed to assess the diagnostic accuracies of cross sectional echocardiography and cineangiography in detecting left ventricular mural thrombi and the effect of anticoagulation treatment on the incidence of such thrombi.

6. Localization of left ventricular ischaemia in angina pectoris by cineangiography during exercise.
Cineangiography of the left ventricle during exercise has been used in an attempt to define the area of ischaemic myocardium in patients suffering from angina pectoris in whom coronary artery surgery was contemplated. A correlation was established between the site of coronary artery obstruction and the area of abnormal myocardial contraction. This method of

8. Comparison of Two-Dimensional Echocardiography, Radionuclide Ventriculography and Cineangiography in Detecting Surgically Documented Left Ventricular Thrombi
To assess the diagnostic value of various imaging techniques for identifying left ventricular thrombi, we studied 35 patients who underwent left ventricular aneurysm repair and inspection of the ventricular cavity for the presence of a thrombus. All patients underwent preoperative two-dimensional echocardiography and left ventricular cineangiography; radionu

9. Digital subtraction angiography in infants and children with congenital heart disease.
Digital subtraction angiography was used as the sole imaging technique in 95 infants and children aged 13 hours to 16 years undergoing cardiac catheterisation for the investigation of congenital heart disease. Injections of diluted contrast medium were made selectively at central sites, and the images were obtained using continuous image intensification fluo

10. Echocardiographic pattern of right atrial tumour motion.
Propagation of Wilm's tumour to the right atrium was diagnosed by echocardiography. The tumour prolapsed into the right ventricle during each atrial systole. The presence of the tumour and its motion were confirmed by cardiac catheterization, cineangiography, and surgical exploration. Successful resection of the tumour was accomplished. Echocardiography was

11. Determination of Cardiac Output and Ejection Fraction with the Dual Cardiac Probe
Cardiac output and left ventricular ejection fraction were determined noninvasively at the bedside in 26 patients by using a dual scintillation probe. The probe is a nonimaging detector that records a high frequency time-activity curve of the passage of an intravenously injected radioactive bolus through the heart. Results were correlated with ejection fract

12. Ejection phase indices of left ventricular performance in infants, children, and adults.
A validatory study of quantitative single plane left ventricular cineangiography is presented, using human left ventricular casts ranging in size from 1.6 to 135 ml. Good correlation was found between actual and calculated volumes (r=0.967). 62 patient studies were carried out and the value of the usually calculated indices of left ventricular performance we
