ABSTRACT

Abstract Objective: To evaluate the efficacy of hybrid transthoracic periventricular device closure of ventricular septal defects (VSDs) in a single center. Methods: All patients who underwent hybrid transthoracic periventricular device closure of VSDs between January 2018 and December 2019 were retrospectively analyzed. The preoperative, operative and postoperative findings and clinical follow-ups were reviewed. Results: A total of 59 patients underwent the procedure. Transesophageal echocardiographic guidance was used in all procedures. The procedure was successful in 57 procedures (97%). The procedures of two patients were changed to open-heart surgery during the same intervention due to severe aortic insufficiency (the device was not deployed) and significant residual shunt after device deployment. One major complication (1.7%) was observed after the procedure. The patient's device was dislodged within 12 hours after the procedure, and this patient underwent device extraction and VSD patch closure due to significant residual shunt. Eight (14%) minor complications were observed after the procedure, and three of them persisted during follow-up. Three of these eight complications were incomplete right bundle branch block, one of which resolved during follow-up; two were mild residual shunts, one of which resolved during follow-up; two were mild new-onset tricuspid valve insufficiencies; and one was mild new-onset mitral valve insufficiency; all valvular insufficiencies were resolved during follow-up. Conclusions: Hybrid transthoracic periventricular device closure of VSD seems to be a good alternative approach due to its procedural success and low risk rates. The best advantage of the procedure is the possibility of switching to open-heart surgery, if necessary.

ABSTRACT

BACKGROUND@#Nitinol-containing devices are widely used in clinical practice. However, there are concerns about nickel release after nitinol-containing device implantation. This study aimed to compare the efficacy and safety of a parylene-coated occluder vs. a traditional nitinol-containing device for atrial septal defect (ASD).@*METHODS@#One-hundred-and-eight patients with ASD were prospectively enrolled and randomly assigned to either the trial group to receive a parylene-coated occluder (n = 54) or the control group to receive a traditional occluder (n = 54). The plugging success rate at 6 months after device implantation and the pre- and post-implantation serum nickel levels were compared between the two groups. A non-inferiority design was used to prove that the therapeutic effect of the parylene-coated device was non-inferior to that of the traditional device. The Cochran-Mantel-Haenszel chi-squared test with adjustment for central effects was used for the comparison between groups.@*RESULTS@#At 6 months after implantation, successful ASD closure was achieved in 52 of 53 patients (98.11%) in both the trial and control groups (95% confidence interval (CI): [-4.90, 5.16]) based on per-protocol set analysis. The absolute value of the lower limit of the 95% CI was 4.90%, which was less than the specified non-inferiority margin of 8%. No deaths or severe complications occurred during 6 months of follow-up. The serum nickel levels were significantly increased at 2 weeks and reached the maximum value at 1 month after implantation in the control group (P  0.05).@*CONCLUSIONS@#The efficacy of a parylene-coated ASD occluder is non-inferior to that of a traditional uncoated ASD occluder. The parylene-coated occluder prevents nickel release after device implantation and may be an alternative for ASD, especially in patients with a nickel allergy.

ABSTRACT

At present, the standard left atrial appendage occlusion procedure mainly involves two-dimensional imaging methods such as X-ray fluoroscopy and transesophageal echocardiography to guide the operation, which will lead to underestimation of the three dimensional structure of the left atrial appendage and the surrounding tissue, thus adversely affects the surgery. To solve this problem, a surgery assist system for left atrial appendage occlusion based on preoperative cardiac CT images is developed. The proposed system realizes the left atrial appendage parameter measurement based on cardiac CT image, and realizes the calculation of optimal delivery sheath trajectory and three-dimensional simulation of the delivery sheath movement on the basis of a novel delivery sheath trajectory model. The system is expected to provide precise guidance for left atrial appendage occlusion, improve the success rate and safety of the operation, and at the same time help reduce the difficulty of learning the operation, and facilitate the promotion of left atrial appendage occlusion.

ABSTRACT

Resumo Fundamento Nos últimos anos, o recente aumento no número de procedimentos intervencionistas tem resultado em crescente preocupação em relação à exposição radiológica por pacientes e equipe médica. A avaliação da exposição dos níveis de radiação em crianças é difícil devido à grande variabilidade no peso corporal. Portanto, os valores de referência de radiação não estão bem definidos para essa população. Objetivos Avaliar e validar a razão do produto dose-área (DAP) em relação ao peso corporal como uma medida de referência de radiação em cateterismos cardíacos em crianças. Métodos Estudo multicêntrico observacional com dados do Registro Brasileiro de Cateterismo Cardíaco em Cardiopatias Congênitas (CHAIN) de março de 2013 a junho de 2014. Os critérios de inclusão foram: pacientes <18 anos submetidos a procedimentos hemodinâmicos para cardiopatia congênita, com DAP devidamente registrado. Foram considerados diferenças estatísticas significativas os valores de p < 0,05. Resultados Este estudo avaliou 429 pacientes com idade e peso medianos de 50 (10, 103) meses e 15 (7, 28) kg, respectivamente. O DAP mediano foi de 742,2 (288,8, 1.791,5) μGy.m2. Houve uma boa correlação entre o DAP e o produto peso/tempo de fluoroscopia (rs=0,66). Não foi observada diferença estatisticamente significativa na relação DAP/peso entre procedimentos terapêuticos e diagnósticos. Houve ampla variação da relação DAP/peso entre os procedimentos terapêuticos (p<0.001). Conclusões A proporção DAP/peso é a medida mais simples e aplicável para avaliar a exposição radiológica em uma população pediátrica. Apesar da escassa literatura disponível, as doses obtidas no presente estudo foram semelhantes àquelas encontradas anteriormente. Estudos de validação e comparação são importantes na avaliação do impacto de estratégias para redução da exposição radiológica nessa população.

Abstract Background In recent years the increasing number of interventional procedures has resulted in growing concerns regarding radiation exposure for patients and staff. The evaluation of radiation exposure in children is difficult due to the great variability in body weight. Therefore, reference levels of radiation are not well defined for this population. Objectives To study and validate the ratio of dose-area product (DAP) to patient weight as a reference measurement of radiation for hemodynamic congenital heart disease procedures in children. Methods This observational multicenter study uses data obtained from a Brazilian registry of cardiac catheterization for congenital heart disease from March 2013 to June 2014. Inclusion criteria were all patients aged <18 years old undergoing hemodynamic procedures for congenital heart disease, with recorded DAP doses. P-value < 0.05 was considered as statistically significant. Results This study evaluated 429 patients with median age and weight of 50 (10, 103) months and 15 (7, 28) kg, respectively. Median DAP was 742.2 (288.8, 1,791.5) μGy.m2. There was a good correlation between DAP and weight-fluoroscopic time product(rs=0.66). No statistically significant difference was observed in DAP/weight ratio between therapeutic and diagnostic procedures. There was a wide variation in the DAP/weight ratio among the therapeutic procedures (p<0.001). Conclusions The DAP/weight ratio is the simplest and most applicable measurement to evaluate radiation exposure in a pediatric population. Although there is limited literature available, the doses obtained in the present study were similar to those previously found. Ongoing research is important to evaluate the impact of strategies to reduce radiation exposure in this population (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

ABSTRACT

Abstract Background: One-catheter strategy, based in multipurpose catheters, allows exploring both coronary arteries with a single catheter. This strategy could simplify coronary catheterization and reduce the volume of contrast administration, by reducing radial spasm. To date, observational studies showed greater benefits regarding contrast consumption and catheterization performance than controlled trials. The aim of this work is to perform the first systematic review and meta-analysis of randomized clinical trials (RCT) to adequately quantify the benefits of one-catheter strategy, with multipurpose catheters, over conventional two-catheter strategy on contrast consumption, and catheterization performance. Methods: A search in PubMed, CINALH, and CENTRAL databases was conducted to identify randomized trials comparing one-catheter and two-catheter strategies. The primary outcome was volume of iodinated contrast administrated. Secondary endpoints, evaluating coronary catheterization performance included: arterial spasm, fluoroscopy time, and procedural time. Results: Five RCT were included for the final analysis, with a total of 1599 patients (802 patients with one-catheter strategy and 797 patients with two-catheter strategy). One-catheter strategy required less administration of radiological contrast (difference in means [DiM] [95% confidence interval (CI)]; −3.831 mL [−6.165 mL to −1.496 mL], p = 0.001) as compared to two-catheter strategy. Furthermore, less radial spasm (odds ratio [95% CI], 0.484 [0.363 to 0.644], p < 0.001) and less procedural time (DiM [95% CI], −72.471 s [−99.694 s to −45.249 s], p < 0.001) were observed in one-catheter strategy. No differences on fluoroscopy time were observed. Conclusions: One-catheter strategy induces a minimal reduction on radiological contrast administration but improves coronary catheterization performance by reducing arterial spasm and procedural time as compared to conventional two-catheter strategy.


Resumen Antecedentes: La estrategia de catéter único permite explorar ambas coronarias con un solo catéter. Nuestro objetivo es realizar la primera revisión sistemática y meta-análisis de ensayos clínicos aleatorizados para cuantificar adecuadamente los beneficios de la estrategia de catéter único, con catéteres multipropósito, sobre la estrategia convencional de dos catéteres. Métodos: Se realizó una búsqueda en PubMed, CINALH y CENTRAL, identificando ensayos aleatorizados que compararan estrategias de un catéter y dos catéteres. El resultado primario fue volumen de contraste administrado. Los secundarios, que evaluaron el rendimiento del cateterismo, incluyeron: espasmo radial, tiempo de fluoroscopia y de procedimiento. Resultados: Se incluyeron cinco ensayos, totalizando 1,599 pacientes (802 con estrategia de un catéter y 797 con estrategia de dos catéteres). La estrategia de catéter único requirió menos contraste (diferencia-de-medias; −3.831 mL [−6.165 mL a −1.496 mL], p = 0.001), presentando menos espasmo radial (odds ratio, 0.484 [0.363 a 0.644], p < 0.001) y menos tiempo de procedimiento (diferencia-de-medias; −72.471 s [−99.694 s a −45.249 s], p < 0.001). No hubo diferencias en el tiempo de fluoroscopia. Conclusiones: La estrategia de catéter único induce una reducción mínima en la administración de contraste, pero mejora el rendimiento del cateterismo al reducir el espasmo radial y el tiempo de procedimiento en comparación con la estrategia convencional.

ABSTRACT

Resumen La enfermedad aneurismática coronaria se define como la dilatación de un segmento arterial coronario más 1,5 veces el diámetro de las arterias adyacentes de tamaño normal. Puede ser difusa, y afectar todo el trayecto de la arteria, o localizada y afectar sólo un segmento arterial específico. Puede encontrarse entre un 3 a un 8% de los estudios angiográficos y entre un 0,22% a un 1,4% de las necropsias clínicas. Se presenta 3 reportes de casos, donde la presentación clínica, los hallazgos angiográficos y el manejo farmacológico es diverso como corresponde a esta entidad.


Abstract Coronary aneurysm disease is defined as the dilation of a coronary artery segment more than 1.5 times the diameter of the adjacent arteries of normal size. It may be diffuse, and affect the whole trajectory of the artery, or localised and only affect a specific arterial segment. It can be found in between 3% and 8% of angiograph studies, with between 0.22% and 1.4% in clinical post-mortems. Three case reports are presented in which the clinical presentation, the angiographic findings, and the pharmacological management are shown to be as diverse as this condition itself.

ABSTRACT

Abstract Objective: To investigate the change in serum Elabela level, a new apelinergic system peptide, in patients with complete atrioventricular (AV) block and healthy controls. Methods: The study included 50 patients with planned cardiac pacemaker (PM) implantation due to complete AV block and 50 healthy controls with similar age and gender. Elabela level was measured in addition to routine anamnesis, physical examination, and laboratory tests. Patients were divided into two groups, with and without AV block, and then compared. Results: In patients with AV block, serum Elabela level was significantly higher and heart rate and cardiac output were significantly lower than in healthy controls. Serum Elabela level was found to be positively correlated with high-sensitive C-reactive protein and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, but negatively correlated with heart rate, high-density lipoprotein cholesterol, and cardiac output. In linear regression analysis, it was found that these parameters were only closely related to heart rate and NT-proBNP. Serum Elabela level was determined in the patients with AV block independently; an Elabela level > 9.5 ng/ml determined the risk of complete AV-block with 90.2% sensitivity and 88.0% specificity. Conclusion: In patients with complete AV block, the serum Elabela level increases significantly before the PM implantation procedure. According to the results of our study, it was concluded that serum Elabela level could be used in the early determination of patients with complete AV block.

ABSTRACT

Resumo Fundamento A intervenção percutânea em pacientes com disfunção de prótese biológica mitral apresenta-se como uma alternativa ao tratamento cirúrgico convencional. Objetivo Relatar a primeira experiência brasileira de implante transcateter de bioprótese valve-in-valve mitral via transeptal (TMVIV-via transeptal). Métodos Foram incluídos pacientes portadores de disfunção de bioprótese cirúrgica submetidos ao TMVIV-transeptal em 12 hospitais brasileiros. Foram considerados estatisticamente significativos valores de p<0,05. Resultados Entre junho/2016 e fevereiro/2019, 17 pacientes foram submetidos ao TMVIV-via transeptal. A mediana de idade foi 77 anos (IIQ,70-82), a mediana do escore STS-PROM foi 8,7% (IIQ,7,2-17,8). Todos os pacientes tinham sintomas limitantes de insuficiência cardíaca (CF≥III), tendo 5 (29,4%) sido submetidos a mais de uma toracotomia prévia. Obteve-se sucesso do TMVIV-via transeptal em todos os pacientes. A avaliação ecocardiográfica demonstrou redução significativa do gradiente médio (pré-intervenção, 12±3,8 mmHg; pós-intervenção, 5,3±2,6 mmHg; p<0,001), assim como aumento da área valvar mitral (pré-intervenção, 1,06±0,59 cm2; pós-intervenção, 2,18±0,36 cm2; p<0,001) sustentados em 30 dias. Houve redução significativa e imediata da pressão sistólica de artéria pulmonar, com redução adicional em 30 dias (pré-intervenção, 68,9±16,4 mmHg; pós-intervenção, 57,7±16,5 mmHg; 30 dias, 50,9±18,7 mmHg; p<0,001). Durante o seguimento, com mediana de 162 dias (IIQ, 102-411), observou-se marcada melhora clínica (CF≤II) em 87,5%. Um paciente (5,9%) apresentou obstrução de via de saída de ventrículo esquerdo (VSVE), evoluindo para óbito logo após o procedimento, e outro morreu aos 161 dias de seguimento.Conclusão: A primeira experiência brasileira de TMVIV-transeptal demonstra a segurança e a efetividade dessa nova técnica. A obstrução da VSVE é uma complicação potencialmente fatal, reforçando a importância da seleção dos pacientes e do planejamento do procedimento.

Abstract Background Percutaneous intervention in patients with bioprosthetic mitral valve dysfunction is an alternative to conventional surgical treatment. Objectives To report the first Brazilian experience with transseptal transcatheter bioprosthetic mitral valve-in-valve implantation (transseptal-TMVIV). Methods Patients with surgical bioprosthetic dysfunction submitted to transseptal-TMVIV in 12 Brazilian hospitals were included. The significance level adopted was p<0.05. Results From June/2016 to February/2019, 17 patients underwent transseptal-TMVIV. Their median age was 77 years (IQR,70-82) and median Society of Thoracic Surgeons predicted risk of mortality (STS-PROM) score was 8.7% (IQR,7.2-17.8). All patients had limiting symptoms of heart failure (FC≥III) and 5 (29.4%) had undergone more than one previous thoracotomy. Transseptal-TMVIV was successful in all patients. Echocardiographic assessment showed a significant reduction in mean mitral valve gradient (pre-intervention, 12±3.8 mmHg; post-intervention, 5.3±2.6 mmHg; p<0.001), in addition to an increase in mitral valve area (pre-intervention, 1.06±0.59 cm2; post-intervention, 2.18±0.36 cm2; p<0.001) sustained for 30 days. There was a significant and immediate reduction in the pulmonary artery systolic pressure, with an additional reduction in 30 days (pre-intervention, 68.9±16.4 mmHg; post-intervention, 57.7±16.5 mmHg; 30 days, 50.9±18.7 mmHg; p<0.001). During follow-up (median, 162 days; IQR, 102-411), significant clinical improvement (FC≤II) was observed in 87.5% of the patients. One patient (5.9%) had left ventricular outflow tract (LVOT) obstruction and died right after the procedure, and another died at 161 days of follow-up. Conclusion The first Brazilian experience with transseptal-TMVIV shows the safety and effectivity of the new technique. The LVOT obstruction is a potentially fatal complication, reinforcing the importance of patients' selection and of procedural planning. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

La mediana para el nivel de dolor en los pacientes fue de 4, la mediana para la comodidad del operador fue de 10 y la mediana para la comodidad en el paciente fue de 10. Se concluye así que el acceso radial distal izquierdo es una alternativa técnicamente factible, ofrece comodidad para el paciente y el operador, y arroja bajas tasas de falla y complicaciones en pacientes seleccionados.


Abstract Objective: To present the experience of one Department in coronary angiography as regards the left distal radius approach through the anatomical snuff box. Material and Method: A total of 40 patients were subjected to coronary angiography through the anatomical snuff box, from April to August 2018. A descriptive analysis was performed on the quantitative variables associated with the procedure (frequency of failed access, failed procedure, procedure time, fluoroscope time, patient pain level, feeling of comfort for the patient and for the operator, amount of contrast used, and some demographic variables). The study included patients over 18 years-old with an indication for coronary angiography for a diagnostic study, and with a palpable pulse in the anatomic snuff box area. Results and conclusion: The mean amount of contrast media employed was 49 ml (SD ± 13), the mean procedure time was 11.3 minutes (SD ± 4.3), and the mean fluoroscope time was 3.3 minutes (SD ± 2.8). The median for the pain level in patients was 4, the median for comfort of the operator was 10, and the median for comfort of the patient was also 10. It was able to be concluded that the left distal radial access is a technically feasible alternative. It is comfortable for the patient and the operator, with low failure rates and complications in selected patients.

ABSTRACT

Abstract The incidence of mitral regurgitation in acute myocardial syndromes is variable. Echocardiographic evaluation is fundamental in making a proper diagnosis of mechanical complications and to offer timely treatment. We present a case of a 64-year-old male who was admitted to the ER in acute pulmonary edema. The electrocardiogram showed negative ST-segment deviation from V4-V6, positive ST-segment deviation in aVR. Multivessel disease with severe mitral regurgitation was seen in catheterization. A transthoracic echocardiogram revealed important mitral regurgitation showing the "tiger stripes" sign, seen in the presence of intracardial oscillating structures, in this case, suspected papillary muscle rupture. Echocardiographic evaluation is necessary in every case of myocardial infarction who present with new-onset mitral regurgitation. Treatment is complex and must be determined with an interdisciplinary group.

ABSTRACT

Introducción: La colocación de stents mediante cateterismo cardiaco en recién nacidos con ciertas cardiopatías congénitas complejas constituye un puente hacia la cirugía correctiva, paliativa o trasplante cardiaco. Objetivo: Evaluar el resultado del implante percutáneo de stents en pacientes recién nacidos con cardiopatías congénitas complejas. Presentación de los casos: Se colocó stents en cinco pacientes; a uno de ellos en la aorta y a los cuatros restantes en el ductus arterioso. Un primer paciente con hipoplasia de cavidades izquierdas en el que predominaba el bajo gasto se le colocó stent en el ductus e inmediatamente se le condujo al salón de operaciones para cerclaje pulmonar. Otro paciente con la misma enfermedad, pero en el que predominaba el hiperflujo pulmonar, se intervino de forma inversa, medió 47 días entre uno y otro proceder. A un tercer paciente, portador de coartación aórtica, se le colocó stent en la aorta y se le hizo cerclaje pulmonar 14 días después del proceder hemodinámico. Las condiciones clínicas del cuarto paciente, con síndrome de hipoplasia de cavidades izquierdas solo permitió colocar stent en el ductus. Esta paciente fallece en evento no relacionado con el cateterismo cardiaco. El último paciente intervenido, portador de una atresia pulmonar, tolera la colocación del stent en el ductus y la evolución clínica posterior demostró que no requería realizar cerclaje pulmonar. Conclusiones: La colocación de stent en el grupo de pacientes analizado es factible y el momento de su implante según el evento hemodinámico apremiante pudiera ser una forma alternativa del cateterismo cardiaco(AU)


Introduction: The paliative placing of stents by cardiac catetherism in new borns with specific congenital hearts diseases is a bridge through a new kind of corrective, paliative surgery or heart transplant. Objective: To evaluate the result of the percutaneous implant of stents in newborn patients with complex congenital heart diseases. Cases presentation: There were placed stents in 5 patients, to one of them in the aorta and to the other four in the ductus arteriosus. The first patient with hypoplasia of the left cavities in which low output predominated had an stent placing in the ductus and he was immediately taken to OR to perform a pulmonary cerclage. Another patients with the same disease but with predominance of pulmonary hyperflow was intervened in the inverse way; there were 47 days between both procedures. A third patient, carrier of aortic coarctation, had an stent placing in the aorta and he also had pulmonary cerclage 14 days after the hemodynamic procedure. The clinical conditions of the fourth patient, who had syndrome of left cavities´ hypoplasia, just allowed to place the stent in the ductus. This patients died in a procedure not related to heart catetherism. The last intervened patient, who was a carrier of pulmonary atresia, tolerated the stent placing in the ductus and the subsequent clinical evolution showed that it was not needed pulmonary cerclage. Conclusions: The stent placing in the analized group of patients is suitable and the moment for its implantation according to the hemodynamic event can be an alternative form of heart catetherism(AU)

ABSTRACT

Abstract Objective: To explore the postoperative changes in inflammatory markers in children who underwent device closure of an atrial septal defect (ASD) via a transthoracic or transcatheter approach. Methods: The experimental and clinical data were retrospectively collected and analyzed for a total of 53 pediatric patients between September 2018 and December 2018. According to the different treatments, 19 patients who underwent transthoracic device closure were assigned to group A, and the remaining 34 patients who underwent a transcatheter approach were assigned to group B. Results: All patients were successfully occluded without any device-related severe complication. Compared with the preoperative levels, the postoperative levels of most inflammatory cytokines in both groups were significantly increased and reached a peak on the first day after the procedure. The level of postoperative inflammatory cytokines was significantly lower in group B than in group A. In addition, there was no significant difference in procalcitonin before and after the transcatheter approach. Conclusion: Systemic inflammatory reactions occurred after transthoracic or transcatheter device closure of ASDs in pediatric patients. However, these inflammatory reactions were more significant in patients who underwent a transthoracic approach than in patients who underwent a transcatheter approach.

ABSTRACT

Abstract Atrial fibrillation (AF) is an increasing health care problem associated with thromboembolic risk about 5% per year, with high mortality and morbidity when associated to stroke. Oral anticoagulants (OAC) are the treatment of choice for preventing ischemic stroke in patients with nonvalvular atrial fibrillation (NVAF). However, these drugs are associated with an increased risk of serious complications such an intracranial hemorrhage (ICH). In this context percutaneous closure of the left atrial appendage (LAA) is an effective therapeutic alternative to OACs, with an increasing success rate. Novel devices might allow or facilitate the procedure in some anatomically and technically complicated cases. Two patients with a complex morphology of the LAA, in which the LAmbre (Lifetech Scientific [Shenzhen] Co. Ltd.) device was implanted with good technical and clinical results are presented.
