This is a study that addresses users' knowledge and feelings about the cardiac catheterization exam. Objective: To describe the perception of the exam in users submitted to a coronary catheterization. Methods: This is a descriptive study with a qualitative approach carried outat the hemodynamics service in a university hospital in the state of Rio de Janeiro, from October to December 2013. Twenty 20 patients, aged between 18 and 79 years old participated in the study. Data collection was carried out through semi-structured interviews, followed by content analysis. Results: most patients were unaware of the purpose of the exam, and felt fear and anxiety associated with death, symbolically or not. Final considerations: patients are not clear about the therapeutic action of cardiac catheterization, opening space for the presence of feelings caused by ignorance. The educational actions carried out by the nurse are a facilitating strategy for health education for these people.

Summary The inflammation of aortic wall, named aortitis, is a rare condition that can be caused by a number of pathologies, mainly inflammatory or infectious in nature. In this context, the occurrence of combined audiovestibular and/or ocular manifestations eventually led to the diagnosis of Cogan's syndrome, making it the rare case, but susceptible to adequate immunosuppressive treatment and satisfactory disease control.
Resumo A inflamação da parede da aorta, denominada aortite, é uma condição clínica rara, que pode ser causada por diversas patologias, principalmente as de fundo inflamatório e/ou infeccioso. Nesse contexto, a ocorrência de sintomas vestibulares e oftalmológicos associados ao quadro remete ao diagnóstico de síndrome de Cogan, tornando o caso raro, mas passível de tratamento imunossupressor adequado e controle satisfatório da doença.

BACKGROUND: Evaluation of left ventricular (LV) size and function is one of the important reasons for performing echocardiography. Real time three dimensional echocardiography (RT3DE) is now available for a precise non-invasive ventricular volumetry. Aim of work was to validate RT3DE as a non-invasive cardiac imaging method for measurement of LV volumes using cardiac angiography as the reference technique. METHODS: Prospective study on 40 consecutive patients with tetralogy of Fallot (TOF) referred for cardiac catheterization for preoperative assessment. Biplane cineangiography, conventional 2 dimensional echocardiography (2DE) and RT3DE were performed for the patients. A control group of 18 age and sex matched children was included and 2DE and RT3DE were performed for them. RESULTS: The mean LV end diastolic volume (LVEDV) and LVEDV index (LVEDVI) measured by RT3DE of patients were lower than controls (p value = 0.004, 0.01, respectively). There was strong correlation between the mean value of the LVEDV and the LVEDVI measured by RT3DE and angiography (r = 0.97, p < 0.001). The mean value of LV ejection fraction measured by RT3DE was lower than that assessed by 2DE (50 ± 6.2%, 65 ± 4.6%, respectively, p value < 0.001) in the studied TOF cases. There was good intra- and inter-observer reliability for all measurements. CONCLUSION: RT3DE is a noninvasive and feasible tool for measurement of LV volumes that strongly correlates with LV volumetry done by angiography in very young infants and children, and further studies needed.

Spontaneous dissection of the celiac trunk is quite an uncommon medical condition, with few case reports in the medical literature. Sudden epigastric abdominal pain is the most common complaint reported by patients, but due to the rarity of this disease in clinical practice and the nonspecific nature of its symptoms, a high degree of clinical suspicion is needed to establish diagnosis. However, improvements in imaging techniques are facilitating diagnosis of this clinical entity, increasing its detection rate. The ideal treatment has not yet been fully established in the literature and the available therapeutic strategies are conservative medical treatment, surgical revascularization or endovascular intervention. In this article we report on three cases of spontaneous dissection of the celiac trunk and conduct a review of the literature on this disease...
A dissecção espontânea do tronco celíaco é uma condição médica incomum, com poucos relatos de casos publicados na literatura médica. A dor abdominal súbita no epigástrio é o sintoma mais frequentemente manifestado pelos pacientes; porém, devido à raridade dessa doença na prática clínica e à inespecificidade de seus sintomas, é necessário um alto grau de suspeição para o estabelecimento do seu diagnóstico. Nesse contexto, o aperfeiçoamento das técnicas de exames de imagem vem possibilitando o diagnóstico desta entidade clínica com maior facilidade, aumentando a sua taxa de detecção. O tratamento ideal ainda não está completamente bem estabelecido na literatura, sendo que as estratégias terapêuticas disponíveis são o tratamento médico conservador, a revascularização cirúrgica e a intervenção endovascular.

Para-anastomotic aneurysms are either true aneurysms or pseudoaneurysms. The latter tend to be asymptomatic until rupture. Para-anastomotic aneurysms should be approached surgically, despite the high morbidity and mortality associated with their treatment. This report describes the case of a 68-year-old woman who presented with a para-anastomotic pseudoaneurysm secondary to infrarenal aortic aneurysmectomy. We chose to use an endovascular approach, and results were good. Endovascular techniques are increasingly becoming the method of choice in the treatment of anastomotic pseudoaneurysms.
Os aneurismas para-anastomóticos de aorta podem ser verdadeiros ou pseudoaneurismas. Estes últimos tendem a ser assintomáticos até a ruptura. Devem ser tratados cirurgicamente, apesar da alta morbimortalidade em sua abordagem. Este relato descreve o caso de uma paciente do sexo feminino, 68 anos, com quadro de pseudoaneurisma para-anastomótico pós-aneurismectomia de aorta infrarrenal. Optou-se por correção endovascular, com bons resultados. As técnicas endovasculares vêm se estabelecendo como o método de escolha no tratamento dos pseudoaneurismas anastomóticos.

The preoperative cardiac assessment of patients undergoing noncardiac surgery is common in the daily practice of medical consultants, anesthesiologists, and surgeons. The number of patients undergoing noncardiac surgery worldwide is increasing. Currently, there are several noninvasive diagnostic tests available for preoperative evaluation. Both nuclear cardiology with myocardial perfusion single photon emission computed tomography (SPECT) and stress echocardiography are well-established techniques for preoperative cardiac evaluation. Recently, some studies demonstrated that both coronary angiography by gated multidetector computed tomography and stress cardiac magnetic resonance might potentially play a role in preoperative evaluation as well, but more studies are needed to assess the role of these new modalities in preoperative risk stratification. A common question that arises in preoperative evaluation is if further preoperative testing is needed, which preoperative test should be used. The preferred stress test is the exercise electrocardiogram (ECG). Stress imaging with exercise or pharmacologic stress agents is to be considered in patients with abnormal rest ECG or patients who are unable to exercise. After reviewing this article, the reader should develop an understanding of the following: (1) the magnitude of the cardiac preoperative morbidity and mortality, (2) how to select a patient for further preoperative testing, (3) currently available noninvasive cardiac testing for the detection of coronary artery disease and assessment of left ventricular function, and (4) an approach to select the most appropriate noninvasive cardiac test, if needed.

A detecção de alterações da motilidade segmentar do ventrículo esquerdo (VE) induzidas por um estresse farmacológico ou físico tem seu papel bem estabelecido na determinação não-invasiva de isquemia miocárdica. Entretanto, em sequência temporal, vários eventos secundários à isquemia ocorrem no miocárdio, sendo a heterogeneidade de perfusão um dos mais precoces a aparecer. Associação de parâmetros a serem analisados durante exames indutores de isquemia para diagnóstico de doença arterial coronária (DAC) tem sido amplamente estudada nos últimos anos. Ecocardiografia sob estresse pela dobutamina-atropina quando associada a contraste de microbolhas permite melhor visibilização dos segmentos do VE e análise da perfusão miocárdica. Ressonância magnética cardiovascular (RMC) é uma técnica que vem sendo amplamente utilizada na investigação de DAC tanto pela análise motilidade segmentar quanto pela análise da perfusão miocárdica, embora a combinação destes parâmetros tenha sido pouco estudada. Os objetivos deste estudo foram: determinar o valor incremental da análise de perfusão miocárdica sobre a análise da motilidade segmentar pela ecocardiografia com perfusão miocárdica em tempo real (EPMTR) e pela RMC e comparar, em um mesmo grupo de pacientes, a acurácia diagnóstica da EPMTR e RMC utilizando o mesmo protocolo sob estresse pela dobutamina-atropina, para detecção de DAC angiograficamente significativa. Estudamos 42 pacientes (média etária de 59 ± 7anos, 20 homens) com suspeita clinica de DAC e indicação de angiografia coronária. Todos os pacientes foram submetidos ao protocolo de estresse pela dobutamina-atropina na EPMTR e na RMC com intervalo de três dias a três meses. Para a obtenção da perfusão foi utilizado o contraste ecocardiográfico perflutreno na EPMTR e o contraste paramagnético baseado em gadolínio na RMC. Análise da motilidade segmentar e perfusão miocárdica foram realizadas, tanto na EPMTR quanto na RMC, por análise visual...
The detection of left ventricular (LV) wall motion abnormalities induced by pharmacological or physical stress has a well established role in the non-invasive determination of myocardial ischemia. However, following the temporal sequence of events in the ischemic cascate, perfusion heterogeneity is one of the earliest and may occur before wall motion abnormalities. In the last years, association between parameters has been demonstrated to improve the diagnoses of coronary artery disease (CAD) during cardiac stress tests. Microbubble-based contrast agent allows for better LV endocardial border delineation and analysis of myocardial perfusion during stress echocardiography. Cardiac magnetic resonance imaging (CMRI) is a technique that has been extensively used to investigate CAD, both for the analysis of wall motion and myocardial perfusion. However, the combination of these parameters has not been completely defined in the literature. The objectives of this study were: to determine the additional value of myocardial perfusion over wall motion analysis with real-time myocardial perfusion echocardiography (RTMPE) and CMRI and to compare, in the same group of patients, the diagnostic accuracy of RTMPE and CMRI using the same dobutamine-atropine stress protocol for detection of angiographically significant CAD. A total of 42 patients were studied (mean age of 59±7 years, 20 men) with clinical suspicion of CAD and indication of coronary angiography. All patients underwent dobutamine-atropine stress protocol during RTMPE and CMRI, with intervals of three days to three months apart. Perflutren contrast agent was used for perfusion analysis by RTMPE, and paramagnetic gadolinium-based contrast was used by CMRI, both injected intravenously. Wall motion and myocardial perfusion were determined by visual analysis both in RTMPE and CMRI using the 17-segment model of the Joint Committee of the American Heart Association. All patients underwent invasive coronary angiography...

<p><b>BACKGROUND</b>Granulocyte colony-stimulating factor (G-CSF) seems to improve cardiac function and perfusion when used systemically through mobilization of stem cells into peripheral blood, but results of previous clinical trials remain controversial. This study was designed to investigate safety and efficacy of subcutaneous injection of G-CSF on left ventricular function in patients with impaired left ventricular function after ST-segment elevation myocardial infarction (STEMI).</p><p><b>METHODS</b>Thirty-three patients (22 men; age, (68.5 +/- 6.1) years) with STEMI and with comorbidity of leukopenia were included after successful primary percutaneous coronary intervention within 12 hours after symptom onset. Patients were randomized into G-CSF group who received G-CSF (10 microg/kg of body weight, daily) for continuous 7 days and control group. Results of blood analyses, echocardiography and angiography were documented as well as possibly occurred adverse events.</p><p><b>RESULTS</b>No severe adverse events occurred in both groups. Mean segmental wall thickening in infract segments increased significantly at 6-month follow up compared with baseline in both groups, but the longitudinal variation between two groups had no significant difference (P > 0.05). The same change could also be found in longitudinal variation of wall motion score index of infarct segments (P > 0.05). At 6-month follow-up, left ventricular end-diastolic volume of both groups increased to a greater extent, but there were no significant differences between the two groups when comparing the longitudinal variations (P > 0.05). In both groups, left ventricular ejection fraction measured by echocardiography ameliorated significantly at 6-month follow-up (P < 0.05), but difference of the longitudinal variation between two groups was not significant (P > 0.05). When pay attention to left ventricular ejection fraction measured by angiocardiography, difference of the longitudinal variation between groups was significant (P = 0.046). Early diastolic mitral flow velocity deceleration time changed significantly at 6- month follow-up in both groups (P = 0.05).</p><p><b>CONCLUSIONS</b>Mobilization of stem cells by G-CSF after reperfusion of infarct myocardium is safe and seems to offer a pragmatic strategy for recovery of myocardial global function.</p>

<p><b>OBJECTIVE</b>The study was performed to observe the angiocardiographic characteristics of patients post bidirectional Glenn procedure.</p><p><b>METHODS</b>Thirty-eight consecutive patients [24 male/14 female, age 0.9 - 28 (7.8 ± 5.6) years] underwent bidirectional Glenn procedure were included in this study. Postoperative cardiac catheterization and angiocardiography were performed at 2 - 7 (4.1 ± 1.9) years after bidirectional Glenn procedure.</p><p><b>RESULTS</b>Of 38 patients, pulmonary arterial mean pressure (PAMP) was (14.8 ± 4.5) mm Hg (1 mm Hg = 0.133 kPa), the mean pressure of superior vena cava (MPSVC) was (15.4 ± 5.4) mm Hg and no pressure gradient was detected. Elevated pulmonary arterial pressure was evidenced in 9 patients: PAMP was (21.5 ± 2.9) mm Hg and MPSVC was (22.9 ± 5.1) mm Hg. Systemic venous collateral channels (SVCC) were shown in 14 patients and PAMP [(16.7 ± 5.7) mm Hg vs. (13.7 ± 3.4) mm Hg, P < 0.05] and MPSVC [(17.8 ± 7.2) mm Hg vs. (14.0 ± 3.6) mm Hg, P < 0.05] were higher in SVCC patients compared to patients without SVCC. Transcatheter closure was successfully performed in 2 patients. Distribution of SVCC was as follows: Posterior SVCC in 12 patients (associated anterior SVCC in 3 patients and middle SVCC in 1 patient), middle SVCC in 2 patients. Pulmonary arteriovenous fistulae were presented in 2 patients. Aortopulmonary collateral arteries were presented in another 2 patients and were successfully occluded percutaneously.</p><p><b>CONCLUSION</b>Catheterization and angiocardiography play an important role in recognizing the complications post bidirectional Glenn procedure.</p>

PURPOSE: Determination of pulmonary to systemic blood flow ratio (QP/QS) is important for the management of patients with left-to-right shunt. This study was performed to assess the agreement of Qp/Qs ratio using the radionuclide method and oxymetry, to investigate the factors influencing the agreement, and to know how interchangeable the results of each technique. MATERIALS AND METHODS: We compared the Qp/Qs measured by single-pass radionuclide angiocardiography and oxymetry during catheterization in 207 patients who underwent both studies. In radionuclide method, Qp/Qs was calculated from the pulmonary time-activity curves using a gamma variate fit. The correlation and Bland-Altman analysis were performed according to the levels of shunt and associated lesions. RESULTS: The mean Qp/Qs was 1.83+/10.50 by radionuclide, and 1.74+/10.51 by oxymetry. The overall correlation coefficient was 0.86(p<0.001), and Bland-Altman range of agreement encompassing 4SD was 1.05. For atrial septal defect, ventricular septal defect, patent ductus arteriosus, tricuspid and mitral insufficiency, the correlation coefficient was 0.78, 0.90, 0.84, 0.63 and 0.44, and Bland-Altman range was 1.52, 0.74, 0.96, 1.57, and 1.50, respectively. CONCLUSION: There is good agreement but wide variance between the Qp/Qs ratios by radionuclide method and oxymetry. Associated atrioventricular valvar insufficiency decreases the correlation coefficient and widens the variance. Wide overall variance suggests that Qp/Qs measurements by two techniques should not be used interchangeably.
