“…This interference, however, is more pronounced in 3D reconstructions than in longitudinal and cross-sectional reformatted images, which are the projections most frequently used for arterial measurement. 8,19,21,22 Images of good diagnostic quality were obtained in all cases, confirming the effectiveness of the protocol used. Quantitative analysis based on both the visual aspect and estimate of blood flow within the stented vessel was effective in that it showed absence of hemodynamically significant in-stent obstructions.…”

objective: To assess the performance of multidetector computed tomography in determining late clinical outcomes of patients undergoing sirolimus-eluting stent implantation.Methods: Thirty patients, successfully submitted to sirolimus-eluting stent implantation for more than six months, were selected to participate in the study. All underwent invasive angiography and intravascular ultrasound following CT angiography using iodinated contrast medium at a dose of 1.5 ml/kg. Results:Mean proximal reference diameter was 3.01 ± 0.31 mm by tomography and 3.14 ± 0.31 mm by angiography (p = 0.04). When the left circumflex artery was excluded from the analysis, the difference between both examinations was no longer significant (tomography = 3.01 ± 0.32 mm; angiography = 3.10 ± 0.30 mm, p = 0.65). Mean distal reference diameter was 2.86 ± 0.30 mm by tomography and 2.92 ± 0.32 by angiography (p = 0.25). Mean in-stent minimal lumen diameter was 2.85 ± 0.25 mm by tomography and 2.85 ± 0.29 mm by angiography (p = 0.27). Mean minimal in-stent crosssectional area was 7.19 ± 1.47 mm 2 by tomography and 6.90 ± 1.52 mm 2 by intravascular ultrasound (p = 0.36), but there was only a weak correlation between these measurements (r = 0.33). Conclusion:Computed tomography allows the qualitative assessment of sirolimus-eluting stents, accurate estimate of proximal and distal reference diameters of the target vessel, and in-stent minimal lumen diameter. Its correlation with measurements performed using intravascular ultrasound, however, is less strong. key words: Coronary failure, computed tomography, quantitative angiography, intravascular ultrasound.

Noninvasive Pacemaker Stress Echocardiography as a Screening Test for Coronary Artery Disease in Patients With Atypical Angina and Permanent Pacemaker

Background and Objectives: Making the noninvasive diagnosis of coronary artery disease in patients with a permanent pacemaker is difficult because of the inability to interpret electrocardiograms and the low specificity of perfusion scintigraphy. We evaluated the diagnostic accuracy of noninvasive pacemaker stress echocardiography (PASE) as a screening test for coronary artery disease in patients with atypical angina and a permanent pacemaker. Subjects and Methods: This a prospective study, and transthoracic stress-pacing echocardiography was performed on 15 patients (9 men and 6 women; age, mean age: 71.1±11.0 years) with atypical angina and a permanent pacemaker. All the patients underwent noninvasive pacemaker-stress echocardiography by external programming (pacing the heart rate up to 150 beats per minute). Coronary angiography was performed on the 8 patients with positive PASE results. Significant coronary artery disease was defined as ≥70% stenosis in at least one major coronary artery. Results: The echocardiographic images were interpretable for all the patients. No significant side effects were observed. The left ventricular systolic function was preserved in all the patients (left ventricular ejection fraction; 63.5±8%). Only 5 (62.5%) of 8 patients showed significant coronary artery disease, as documented by coronary angiography. Conclusion: Noninvasive PASE is a simple, rapid, safe and diagnostically efficient test for detecting coronary artery disease in patients with atypical angina and a permanent pacemaker. Larger studies are necessary to validate our findings.

Doppler echocardiography is a simple, fast and noninvasive method to identify abnormal regional or global left ventricular function. One could consider this non-invasive method to be the best approach of all imaging techniques.Stress echocardiography techniques are used for the diagnosis, risk stratification, prognosis and the study of myocardial viability in ischemic heart disease. There are many ways of subjecting the heart to stress for echocardiographic studies. For physically fit patients exercise stress testing using a treadmill or bicycle is employed and patients who are unable to exercise undergo pharmacological tests.Although accurate diagnosis and a high prognostic value are achieved with both methods, there are new techniques under study, including the utilization of echocardiographic microbubble contrast for endocardial edge evaluation and for myocardial perfusion studies. Descriptors: Stress. Echocardiography. Coronary disease.Resumo A ecodopplercardiografia é uma metodologia simples, rápida e não invasiva para identificar anormalidades regional e global da função do ventrículo esquerdo, podendo ser considerado o método não invasivo de maior aplicabilidade dentro das técnicas de imagem.A ecocardiografia sob estresse é utilizada para diagnóstico, estratificação de risco, prognóstico e avaliação da viabilidade miocárdica na doença arterial coronariana. Várias são as formas de se submeter o coração ao estresse para o estudo ecocardiográfico. Para indivíduos com capacidade física preservada, utiliza-se o teste com esteira ou bicicleta e para aqueles sem condições de se exercitar, são usados os testes farmacológicos.Apesar da boa acurácia diagnóstica e do valor prognóstico com os dois métodos já referidos, novas técnicas vêm sendo estudadas, como a utilização do contraste ecocardiográfico com microbolhas para avaliação das bordas do endocárdio e o estudo da perfusão miocárdica.Descritores: Estresse.
