RESUMO

@#Objective    To analyze the early outcomes of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) patients with severe left ventricular dysfunction after surgical repair, and to explore the predictors for extracorporeal membrane oxygenation (ECMO) support for these patients. Methods    The clinical data of ALCAPA patients with severe left ventricular dysfunction (left ventricular ejection fraction<40%) who underwent coronary artery reimplantation in the pediatric center of our hospital from 2013 to 2020 were retrospectively analyzed. The patients were divided into an ECMO group and a non-ECMO group. Clinical data of the two groups were compared and analyzed. Results    A total of 64 ALCAPA patients were included. There were 7 patients in the ECMO group, including 4 males and 3 females aged 6.58±1.84 months. There were 57 pateints in the non-ECMO group, including 30 males and 27 females aged 4.34±2.56 months. The mortality of the patients was 6.25% (4/64), including 2 patients in the ECMO group, and 2 in the non-ECMO group. The postoperative complications rate was significantly higher in the ECMO group than that in the non-ECMO group (P=0.041). There were statistical differences in the cardiopulmonary bypass time [254 (153, 417) min vs. 106 (51, 192) min, P=0.013], aortic cross-clamping (ACC) time (89.57±13.66 min vs. 61.58± 19.57 min, P=0.039), and preoperative left ventricular end-diastolic diameter/body surface area (132.32±14.71 mm/m2 vs. 108.00±29.64 mm/m2, P=0.040) between the two groups. Multivariate logistic regression analysis showed that ACC time was an independent risk factor for postoperative ECMO support (P=0.005). Receiver operating characteristic (ROC) curve analysis showed that the area under the ROC curve was 0.757, the sensitivity was 85.70%, specificity was 66.70%, with the cut-off value of 66 min. Conclusion    ACC time is an independent risk factor for postoperative ECMO support. Patients with an ACC time>66 min have a significantly higher risk for ECMO support after the surgery.

RESUMO

This paper aimed to study the effect of Dalbergia cochinchinensis heartwood on plasma endogenous metabolites in rats with ligation of the left anterior descending coronary artery, and to analyze the mechanism of D. cochinchinensis heartwood in improving acute myocardial ischemic injury. The stability and consistency of the components in the D. cochinchinensis heartwood were verified by the establishment of fingerprint, and 30 male SD rats were randomly divided into a sham group, a model group, and a D. cochinchinensis heartwood(6 g·kg~(-1)) group, with 10 rats in each group. The sham group only opened the chest without ligation, while the other groups established the model of ligation. Ten days after administration, the hearts were taken for hematoxylin-eosin(HE) staining, and the content of heart injury indexes in the plasma creatine kinase isoenzyme(CK-MB) and lactate dehydrogenase(LDH), energy metabolism-related index glucose(Glu) content, and vascular endothelial function index nitric oxide(NO) was determined. The endogenous metabolites were detected by ultra-high-performance liquid chromatography-time-of-flight-mass spectrometry(UPLC-Q-TOF-MS). The results showed that the D. cochinchinensis heartwood reduced the content of CK-MB and LDH in the plasma of rats to relieve myocardial injury, reduced the content of Glu in the plasma, improved myocardial energy metabolism, increased the content of NO, cured the vascular endothelial injury, and promoted vasodilation. D. cochinchinensis heartwood improved the increase of intercellular space, myocardial inflammatory cell infiltration, and myofilament rupture caused by ligation of the left anterior descending coronary artery. The metabolomic study showed that the content of 26 metabolites in the plasma of rats in the model group increased significantly, while the content of 27 metabolites decreased significantly. Twenty metabolites were significantly adjusted after the administration of D. cochinchinensis heartwood. D. cochinchinensis heartwood can significantly adjust the metabolic abnormality in rats with ligation of the left anterior descending coronary artery, and its mechanism may be related to the regulation of cardiac energy metabolism, NO production, and inflammation. The results provide a corresponding basis for further explaining the effect of D. cochinchinensis on the acute myocardial injury.

RESUMO

The transcatheter left atrial appendage occluding device, WATCHMAN, can be used to prevent thromboembolism in patients with nonvalvular atrial fibrillation who are at high risk of bleeding during anticoagulation. We report an emergent surgical case of cardiac tamponade due to the left atrial appendage perforation with the WATCHMAN device implantation. An 83-year-old woman with recurrent paroxysmal atrial fibrillation (CHA2DS2-VASc score 4, HAS-BLED score 3) after catheter ablation was scheduled for the WATCHMAN device implantation. During implantation, the patient developed cardiac tamponade and underwent emergent surgery with cardiopulmonary bypass for active bleeding despite pericardial drainage. The bleeding was caused by the left atrial appendage perforation, and suture exclusion of the left atrial appendage was performed.

RESUMO

Anomalous aortic origin of a coronary artery is a rare congenital anomaly that can cause myocardial ischemia and ventricular arrhythmia. This disease initially manifests as cardiac arrest in half of patients. The indications and surgical strategy remain unclear, especially in patients who are asymptomatic and have poor ischemic findings. We report a surgical strategy to treat anomalous aortic origin of the right coronary artery. A 47-year-old man with a chief complaint of chest tightness was diagnosed with anomalous aortic origin of the right coronary artery, which branches from the left sinus of Valsalva and runs an inter-arterial course. Although no objective myocardial ischemia was identified with blood tests, electrocardiography, or cardiac catheterization, we suspected that the cause of the thoracic symptoms was sharp branching of the right coronary artery, which was compressed between the ascending aorta and the pulmonary artery. To reduce the risk of sudden death in the future, we performed reimplantation of the right coronary artery. Good imaging results were obtained, and the patient is currently undergoing outpatient follow up and has not experienced recurrence of chest symptoms. We conclude that our surgical strategy to treat anomalous aortic origin of a coronary artery may be useful in the clinic.

RESUMO

The patient was a six-month-old girl with an anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA). She had fever and visited a family physician at 5 months of age. Because of poor oxygenation, she was referred to our pediatric department and intubated soon after hospitalization. Echocardiography showed that the orifice of left coronary artery was just above pulmonary commissure, the left ventricular ejection fraction was 9%, and the level of mitral regurgitation was moderate. Right coronary angiography showed that the left coronary artery contrasted against the collateral arteries. The left coronary artery originated from the left side of the pulmonary trunk. After recovery of the general condition with medical therapy, the patient underwent coronary artery reconstruction by the modified spiral cuff technique on the 21st day of hospitalization. The temporary detachment of pulmonary valve and its commissure for making a margin around the left coronary artery enabled us to make the spiral cuff in almost the usual manner. She was moved to the intensive care unit with the support of extracorporeal membrane oxygenation (VA-ECMO) and was successfully weaned off the VA-ECMO 5 days after the surgery. The postoperative course was good, and she was discharged from our hospital 3 months after the surgery. The echocardiogram one year after the surgery showed a left ventricular ejection fraction of 30%, mild mitral regurgitation, and mild pulmonary regurgitation. Our experience indicates that the spiral cuff technique is a useful coronary reconstruction method for the treatment of ALCAPA, especially in cases presenting a considerable distance between the origin of the left coronary artery and the transplantation site. There are few reports regarding the surgical treatment of infantile ALCAPA showing reduced left ventricular function. Coronary artery reconstruction using the spiral cuff method and planned VA-ECMO are useful surgical procedures in such cases. Our experience also suggests that the establishment of a treatment strategy including mechanical support is essential to improve the results in severe ALCAPA cases.

RESUMO

Unroofed coronary sinus syndrome (UCSS), also named coronary sinus septal defect, is a rare type of atrial septal defect with the incidence less than 1% of the total number of atrial septal defects. It is caused by incomplete formation of left atrial venous folds during embryonic development. Here we reported a patient with UCSS, who was treated in the Second Xiangya Hospital of Central South University. The patient was 50 years old and the main clinical manifestations were fatigue and shortness of breath after repeated exercise. Color Doppler echocardiography showed coronary sinus dilatation (17 mm×14 mm), indicating the possibility of permanent left superior vena cava. Pulmonary angiography showed that the left ventricle and coronary sinus were developed at the same time while the atrial septum was intact after the development of the left atrium, followed by the right atrium and right ventricle, indicating a partial anomalous pulmonary venous drainage (intracardiac type). Finally, the cardiac computed tomograhic angiography showed that 4 pulmonary veins and permanent left superior vena cava (PLSVC) went into the left atrium and the coronary sinus, respectively, while the coronary sinus septum was absent and the PLSVC was connected with the left atrium. The patient was later treated with the correction of non-parietal sinus syndrome in the Cardiovascular Surgery Department of our hospital.

RESUMO

A 55-year-old man was brought to our hospital with a knife penetrating his left anterior chest wall following a suicide attempt. Massive left hemothorax was identified on echocardiography ; however, there was no evidence of cardiac tamponade. After draining blood from the left thorax, computed tomography (CT) revealed that the tip of the knife had penetrated the left lung and reached the left pulmonary vein. In preparation for cardiopulmonary bypass, an emergency thoracotomy was scheduled with a plan to access the left lung and left pulmonary vein. The patient was transferred to the operating room, and the procedure was started with the patient in the supine position. During dissection of the femoral vessels, the patient suddenly developed hypotension. After surgical access to the heart was achieved via median sternotomy, a pericardiotomy was performed and cardiopulmonary bypass was established. A 50-mm stab wound was identified at the lateral wall of the left ventricle. The knife was removed, and the left ventricular wound was repaired. The lingular segment of the left lung was partially resected. The patient had no postoperative complications and was transferred to the referral hospital on postoperative day 25. This case report emphasizes the importance of taking appropriate measures for thoracotomy and cardiopulmonary bypass in patients with penetrating thoracic trauma with massive hemothorax, even in the absence of cardiac tamponade on imaging. We were able to successfully manage a life-threatening condition by taking appropriate measures.

RESUMO

Background : The surgical repair of acute aortic dissection type A [AAD (A)] by reconstructing the left subclavian artery (LSCA) is sometimes difficult because of the deep surgical field and the occurrence of left recurrent nerve palsy or bleeding. In Japan, since 2014, a commercially available open stent graft (J-graft OPEN STENT) has been used for promoting thrombosis of the false lumen in the descending aorta. This report presents an efficacy evaluation of the surgeon-made in situ Fenestrated Open Stent (FeneOS) for LSCA reconstruction in a patient with AAD (A). Method : We performed surgery with FeneOS using the open stent graft by first deploying it from the entry of the LSCA into the descending aorta and manually making a hole on the LSCA side of the stenting portion ; then, the four-branched J graft was anastomosed between the left common carotid (lt. CCA) and SCA (ZONE 2). At our institution, 47 patients with AAD (A) underwent this surgery with FeneOS from 2014 to 2019 (FeneOS group) and 97 patients with AAD (A) underwent a normal open-stenting procedure from 2008 to 2014 (non-FeneOS group). We analyzed the postoperative results of patients in the FeneOS and non-FeneOS groups. Results : Preoperative characteristics of patients in both groups were similar. Patients in the FeneOS group had an acceptable postoperative course, with no 30-day or in-hospital deaths. The mean operation time, cardiopulmonary bypass time, selective cerebral perfusion time, and open distal anastomosis time were significantly shorter in patients in the FeneOS group (p<0.01). None of the patients had left recurrent nerve palsy, and postoperative computed tomography or arterial echo showed that the blood flow through the LSCA was intact and revealed no endoleakage. Conclusion : FeneOS is simple, fast, and less invasive for the reconstruction of the LSCA without the risk of left recurrent nerve palsy and can be effective for treating patients with AAD (A).

RESUMO

La dilatación de la aurícula izquierda (AI) se considera un predictor ecocardiográfico para la remodelación auricular y la fibrilación auricular. Por ende, hemos investigado la correlación existente entre la dilatación de la AI con las arritmias cardíacas y los trastornos del sistema de conducción en pacientes con hipertensión arterial (HTA). En este estudio observacional y prospectivo hemos investigado las variaciones electrocardiográficas, mediciones ecocardiográficas y Holter ECG de 24 hs en pacientes hipertensos y no hipertensos ambulatoria y hospitalizados que acuden a un hospital terciario entre marzo a septiembre del 2018. Se estudiaron 104 pacientes, 65 hipertensos conocidos y 39 no hipertensos como grupo control. El diámetro promedio de la AI fue significativamente mayor (p=0,03) en pacientes hipertensos que los no hipertensos (37±8 mm vs. 34±5 mm). Se encontró una asociación significativa entre hipertensión y la aurícula izquierda dilatada (>40 mm) (p= 0,026 OR: 3,25 IC95%: 1,01-11,02). La dilatación de la AI tuvo una especificidad de 73% y un valor predictivo negativo de 98% relacionado con la presencia de trastornos del sistema de conducción y arritmias cardiacas en pacientes con HTA. Se encontró asociación entre la hipertensión arterial y la dilatación de la aurícula izquierda. La dilatación de la aurícula izquierda tiene una elevada especificidad y un alto valor predictivo negativo en la detección de la presencia de prolongación del intervalo QT, ensanchamiento del complejo QRS, dispersión de la onda P, y trastornos del sistema de conducción y arritmias cardiacas en pacientes con hipertensión arterial(AU)


Dilation of the left atrium (LA) is considered an echocardiographic predictor for atrial remodeling and atrial fibrillation. Therefore, we have investigated the correlation between dilatation of the LA with cardiac arrhythmias and conduction system disorders in patients with systemic arterial hypertension. In this observational and prospective study we have investigated electrocardiographic variations, echocardiographic measurements and Holter ECG of 24 hours in hypertensive patients who attend a tertiary hospital from March 2018 to September 2018 as outpatients and inpatients. One hundred four patients were studied, 65 known to be hypertensive and 39 non-hypertensive subjects as control group. The diameter of the LA ​​had a mean value of 37±8 in hypertensive patients, while in non-hypertensive patients was 34±5 ​​(p = 0.03). A significant association was found between hypertension and increased diameter of the LA (p = 0.04 OR: 2.6 CI 0.88-7.7). Dilatation of the LA had a specificity of 73% and a negative predictive value of 98% related to the presence of conduction system disorders and cardiac arrhythmias in patients with hypertension. A significant relationship between arterial hypertension and dilatation of the left atrium was observed. The dilatation of the left atrium has a high specificity and a high negative predictive value in the detection of the presence of prolongation of the QT interval, widening of the QRS complex, dispersion of the P wave, and disorders of the conduction system and cardiac arrhythmias in patients with hypertension(AU)

RESUMO

Objective@#To explore the clinical manifestations, diagnosis, treatment and prognosis of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) .@*Methods@#A retrospective study identified 91 patients diagnosed with ALCAPA at Shanghai Children′s Medical Center from March 2010 to August 2017. According to the left ventricular ejection fraction (LVEF) at the time of consultation, patients were divided into the cardiac insufficiency group (n=54) and the normal cardiac function group (n=37). Clinical features (age of onset, clinical performance, etc) and auxiliary examinations (electrocardiogram, echocardiography, etc) between the two groups were compared using a t-test and a Chi-square test. Prognostic factors were analyzed by an ordered logistic regression and a Pearson correlation coefficient.@*Results@#(1) The age of diagnosis of patients in the cardiac insufficiency group who were usually misdiagnosed as cardiomyopathy was (10.0±2.6) months (20/54) , whereas the age of diagnosis of patients in the normal cardiac function group who were usually misdiagnosed as valvular diseases was (40.0±7.8) months (4/37). According to the pathophysiological mechanism, forty of the 54 (74%) patients in the cardiac insufficiency group were infantile type, and 78% patients (29/37) in the normal cardiac function group were adult type. (2) Preoperative electrocardiogram showed the deep Q wave in lead I occurred more frequently in the cardiac insufficiency group than in the normal cardiac function group (28/54 vs. 11/37, χ2=4.388, P=0.036). (3) Twenty patients died in the cardiac insufficiency group including 12 patients who died from postoperative cardiac pump failure and 8 children who did not undergo surgery due to poor prognosis and died from other reasons. There was no death in the normal cardiac function group. (4) Preoperative LVEF was the unique risk factor affecting prognosis (F=16.872, P=0.005). The preoperative LVEF was significantly lower than the postoperative LVEF ((37±11)% vs. (45±14)%, t=3.614, P=0.001) in the cardiac insufficiency group. During the follow-up period, 6 patients in the cardiac insufficiency group still presented with postoperative cardiac dysfunction, and the patients in the normal cardiac function group still had normal cardiac function.@*Conclusions@#Preoperative LVEF was the unique risk factor affecting prognosis of ALCAPA. Patients with infantile type ALCAPA and preoperative cardiac insufficiency should receive long-term follow-up treatment.

RESUMO

Antecedentes: el síndrome de hipoplasia del ventrículo izquierdo es un conjunto de alteraciones del corazón fetal que condicionan un hipodesarrollo del corazón izquierdo, que es insuficiente para mantener la circulación sistémica. El corazón derecho se encuentra dilatado e hipertrofiado y soporta la circulación pulmonar y la circulación sistémica fetal a través del conducto arterioso permeable. Representa el 2 a 3% de todas las cardiopatías congénitas. Sin embargo, la incidencia real está subestimada ya que es responsable de abortos espontáneos y otras muertes fetales intrauterinas no diagnosticadas. Reporte de un caso: paciente de sexo femenino, 32 años de edad, con antecedente familiar de importancia (padre con fibrilación auricular). Antecedentes gíneco-obstétricos: un parto céfalo-vaginal, sin complicaciones, de un neonato de sexo masculino que actualmente tiene 6 años de edad. Durante su segunda gesta el feto es diagnosticado de hipoplasia del ventrículo izquierdo y atresia de la válvula mitral a las 34 semanas. Acude al Hospital Metropolitano a las 39 semanas de gestación para terminación de su embarazo mediante parto céfalo-vaginal. El parto no tuvo complicaciones; al nacimiento se confirma el diagnóstico prenatal y el recién nacido fallece en las primeras 72 horas. Conclusiones: el síndrome de hipoplasia del corazón izquierdo es una combinación compleja de malformaciones cardíaca;, debe ser detectado durante la evaluación ecográfica prenatal para planificar su manejo al nacimiento en centros especializados donde sea posible realizar procedimientos con el propósito de mejorar la supervivencia de estos pacientes.


Background: It is a set of alterations of the fetal heart that condition a hypodevelopment of the left heart, which is insufficient to maintain the systemic circulation. The right heart is dilated and hypertrophied and it supports the pulmonary circulation and fetal systemic circulation through patent ductus arteriosus. It represents 2 - 3% of all congenital heart diseases. However, current incidence is underestimated because it produces spontaneous abortions and other undiagnosed intra- uterine fetal deaths. Report of a case: a 32-year-old female patient with an importance family history: father with atrial fibrillation. Obstetric-gynecological antecedents: a cephalo- vaginal delivery without complications who was a male product of 6 years. During her second pregnancy, fetus was diagnosed with left ventricular hypoplasia and mitral valve agenesis at 34 weeks. She went to Metropolitan Hospital at 39.1 weeks to finish her pregnancy due to cephalo-vaginal birth. Delivery occurred without complications, however, the prenatal diagnosis was confirmed and the newborn died in 72 hours. Conclusions: The left heart hypoplasia syndrome is a complex combination of cardiac malformations; it can be detected with a prenatal evaluation with ultrasound which provides an option to pose treatment and also it can guide physicians to prepare for postnatal interventions when it is necessary.

RESUMO

Aims Three-dimensional rotational angiography (3DRA) of the left atrium (LA) and the esophagus is a simple and safe method for analyzing the relationship between the esophagus and the LA during catheter ablation of atrial fibrillation. The purpose of this study is to describe the location of the esophagus relative to the LA and mobility of the esophagus during ablation procedure. Methods From 3/2011 to 9/2015, 3DRA of the LA and esophagus was performed in 326 patients before catheter ablation of atrial fibrillation. 3DRAwas performed with visualization of the esophagus via peroral administration of a contrast agent. The positions of the esophagus were determined at the beginning of the procedure, for part of patients also at the end of procedure with contrast esophagography. Results The most frequent position is behind the center of the LA (91 pts., 31.9%) The least frequent position is behind the right pulmonary veins (27 pts., 9.4%). The average shift of the esophagus position was 3.36 ± 2.15 mm, 3.59 ± 2.37 mm and 3.67 ± 3.23 mm for superior, middle and inferior segment resp. Conclusions The position of the esophagus to the LA is highly variable. The most common position of the esophagus relative to the LA is behind the middle and left part of the posterior wall of the LA. The least frequently observed position is behind the right pulmonary veins. No significant position change of esophagus motion from before to after the ablation procedure in the majority (≥95%) of the patients was observed.

RESUMO

Persistent right umbilical vein (PRUV) is a common anomaly of the venous system. Although candidates for future PRUV were expected to occur more frequently in earlier specimens, evaluation of serial horizontal sections from 58 embryos and fetuses of gestational age 5–7 weeks found that only two of these embryos and fetuses were candidates for anomalies. In a specimen, a degenerating right umbilical vein (UV) joined the thick left UV in a narrow peritoneal space between the liver and abdominal cavity, and in the other specimen, a degenerating left UV joined a thick right UV in the abdominal wall near the liver. In these two specimens, the UV drained into the normal, umbilical portion of the left liver. These results strongly suggested that, other than the usual PRUV draining into the right liver, another type of PRUV was likely to consist of the right UV draining into the left liver.

RESUMO

RESUMO O presente artigo analisa a trajetória política da segunda geração de exilados brasileiros pelo regime militar no Chile e na França, visando compreender a dinâmica das transformações dos repertórios de ação dos migrantes frequentemente observadas nos estudos sobre exílio. Verificou-se que a migração forçada promove uma metamorfose total da estrutura de oportunidades políticas. Como resultado, o exilado se vê inserido em uma estrutura que não é a mesma daquela verificada pelos estudos sobre o confronto político nos enfrentamentos no interior do Estado-Nação e nem mesmo pelos movimentos transnacionais globais mais atuais. Com efeito, no Chile os exilados apresentaram um repertório adaptado às particularidades do exílio chileno, tendo como foco a continuidade do confronto travado com o regime brasileiro. Na França, por sua vez, eles viveram transformações profundas, ao abandonar o projeto revolucionário e adotar os direitos humanos e a democracia, entre outras reivindicações até então novas para a esquerda brasileira.


ABSTRACT The following article analyzes the political trajectory of the second generation of Brazilians exiled by the military dictatorship to Chile and France, aiming to understand the dynamic characterizing the transformations of the repertoires of action among migrants frequently observed in studies on exile. It also investigates how forced migration promotes a complete metamorphosis of the structure of political opportunities, leaving the exile inserted in a structure that is distinct from that identified by studies on contentious politics in conflicts inside the Nation-State and from that characterizing the most recent global transnational movements. In fact, exiles in Chile revealed a repertoire adapted to the particularities of exile in Chile, focusing on the continuity of the clash with the Brazilian regime. In France, on the other hand, profound transformations occurred, through an abandoning of the revolutionary project and an adoption of human rights and democracy, among other assertions that were new at the time to the Brazilian left.


RÉSUMÉ Le présent article analyse la trajectoire politique de la seconde génération d'exilés brésiliens s'étant installée au Chili et en France durant le régime militaire, dans le but de comprendre la dynamique des transformations - souvent observées dans les études sur l'exil - des répertoires d'action de ces migrants. On a vérifié que la migration forcée promeut une métamorphose totale de la structure des opportunités politiques. Par conséquent, les exilés se voient insérer dans une structure différente de celle qu'ont pu identifier les études sur la confrontation politique dans le cadre de l'État-nation, mais également de celle que l'on peut observer dans les mouvements transnationaux les plus actuels. Au Chili, les exilés ont adapté leur répertoire aux particularités de l'exil chilien en se concentrant sur la continuité de la confrontation en œuvre avec le régime brésilien. D'un autre côté, en France, ils vécurent de profondes transformations et abandonnèrent le projet révolutionnaire pour adopter les droits de l'Homme et la démocratie, entre autres revendications alors nouvelles pour la gauche brésilienne.


RESUMEN El presente artículo examina la trayectoria política de la segunda generación de exiliados brasileños en Chile y en Francia como consecuencia del régimen militar brasileño y busca comprender la dinámica de las transformaciones de los repertorios de acción de los migrantes frecuentemente analizadas en los estudios sobre el exilio. Sugerimos que la migración forzada promueve una metamorfosis total de la estructura de oportunidades políticas. Como resultado, el exiliado se ve envuelto en una disposición que no es la mostrada por los estudios sobre la confrontación política en el ámbito interno del Estado-nación ni tampoco por los movimientos transnacionales globales más actuales. De hecho, en Chile los exiliados presentaron un repertorio adaptado a las particularidades del exilio chileno, centrado en la continuidad del enfrentamiento mantenido con el régimen brasileño. En Francia, por su parte, vivieron transformaciones profundas como consecuencia del abandono del proyecto revolucionario y la adopción del respeto de los derechos humanos y la democracia, entre otras reivindicaciones desconocidas hasta entonces para la izquierda brasileña.

RESUMO

<p>Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly. This anomaly occurs in approximately one in 300,000 live births. Of the children diagnosed with this syndrome, 90% die within the first year of life because of myocardial ischemia and left ventricular failure. Survival into adulthood is rare and depends upon pre-existing or rapidly developing collateral vessels between the right and left coronary artery. This report concerns the surgical case of anomalous origin of the circumflex coronary artery from the left pulmonary artery complicated with atrial septal defect (ASD). A 34-year-old woman was admitted because of dyspnea on exertion. Echocardiography revealed normal cardiac function with secondary ASD. Coronary catheterization revealed an anomalous origin of the left circumflex coronary artery from the left pulmonary artery. Direct closure of the ASD and coronary artery bypass grafting for the circumflex coronary artery using an internal thoracic artery were performed, and the orifice of the circumflex coronary artery was ligated. The postoperative outcome was excellent. Most of the ALCAPA cases shows the main trunk of the left coronary artery arising from the pulmonary artery. This case demonstrates only the left circumflex coronary artery originating from the left pulmonary artery. Moreover ASD coexisted in this case. To the best of our knowledge, this is a very rare case of its type to be diagnosed and reported.</p>

RESUMO

Objective To investigate the preoperative diagnosis,surgical treatment and results of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA).Methods We retrospectively analyzed the clinical data of 9 patients with ALCAPA who had undergone surgical treatment in Shanxi Children's Hospital from June 2010 to March 2014.Results There were 3 males and 6 females,aged from 4 months to 4 years old and 6 months,average age (1.14 ± 1.33)years,body weight from 5.6 to 18.0 kg,average weight(8.06 ± 3.99) kg.Echocardiography and spiral CT angiography were performed in all patients,one of which underwent cardiac catheter angiography.The cases of mitral regurgitation were mild in 2 cases,mild to moderate in 5 cases,and moderate to severe in 2 cases.Electrocardiogram showed abnormal Q wave,ST segment change and T wave inversion in lead Ⅰ,AVL and V4-6 in 9 cases.The X-ray sign was significant heart enlargement(C/T ratio 0.56-0.73,mean 0.61 ± 0.05).Echocardiography indicated ALCAPA,significant enlargement of left ventricle and decreased myocardial contractility(ejection fraction less than 50%).End diastolic diameter of left ventricle were more than 35 mm in 8 cases and aneurysm formation of left ventricular apex in 1 case.One case was confirmed ALCAPA by catheter angiography.Six cases had radioactive nuclide myocardial imaging,which showed different degree of myocardial infarction.All patients underwent reimplantation of left coronary artery into the aorta,mitral valvoplasty in 7 patients.One case died for low cardiac output syndrome.Others recovered and discharged.Postoperative complications included low cardiac output syndrome in 2 cases,pneumonia in 3 cases and supraventricular tachycardia in 1 case.During a followup of 3 months to 2 years,well development,good heart function,mitral valve regurgitation and ejection fraction improved in all case.Conclusion Echocardiography has important value in diagnosis of ALCAPA,which are confirmed by spiral CT angiography and catheter angiography.Preoperative nuclide examination for determinant of survival myocardium is helpful for surgery and prognosis.Reimplantation of left coronary artery into the aorta is the most ideal surgical procedure.
