Coração em Criss-Cross: um relato de caso / Criss-Cross Heart: a case report

Coração em criss-cross (ou coração entrecruzado) foi descrito pela primeira vez em 1974. Trata-se de uma malformação cardíaca congênita, rara, ocorrendo 8 casos a cada 1.000.000 de crianças, e representando somente 0,1% das malformações congênitas. Os métodos diagnósticos de escolha são o ecocardiograma transtorácico, a ressonância magnética cardíaca (RMC), a angiotomografia (TC) e, eventualmente, o cateterismo cardíaco. Neste relato, descreve-se o caso de um recém-nascido com coração em criss-cross somado à dupla via de saída do ventrículo direito (VD), com vasos mal posicionados, além de comunicação interatrial (CIA), comunicação interventricular (CIV), displasia de valva tricúspide e veia cava superior esquerda persistente. Não se sabe a etiologia exata dessa malformação, mas parece ocorrer pela rotação dos ventrículos em seu eixo longitudinal, não acompanhada das rotações atrial e das valvas atrioventriculares (AV). Esse movimento produz uma alteração das vias de entrada dos ventrículos, determinando que o VD se posicione em plano superior e o esquerdo em plano inferior. Apesar de ainda não se saber a exata causa dessa anomalia, acredita-se que uma alteração genética possa estar levando a esses casos: a mutação do gene Cx43. O diagnóstico do caso em questão foi dado pela ecocardiografia transtorácica e da TC de aorta e artérias pulmonares, que mostraram, além do criss-cross, outras alterações, como dupla via de saída do VD, CIA e CIV amplas.(AU)

Criss-cross heart was first described in 1974. It is a rare congenital heart malformation that occurs in 8 cases per 1,000,000 children, and represents only 0.1% of congenital malformations. The diagnostic methods of choice are transthoracic echocardiography, cardiac magnetic resonance (CMR), computed tomography angiography (CT) and, sometimes, cardiac catheterization. This report describes the case of a newborn with a criss-cross heart in addition to double-outlet right ventricle (RV), with poorly positioned vessels, in addition to atrial septal defect (ASD), interventricular septal defect, tricuspid valve dysplasia and persistent left superior vena cava. The exact etiology of this malformation is not known, but it seems to occur due to rotation of the ventricles in their longitudinal axis, not accompanied by rotation of the atrial and atrioventricular (AV) valves. This movement produces abnormal ventricular inlets, determining that the RV be positioned on a superior plane and the left ventricle on an inferior plane. Although the exact cause of this anomaly is still unknown, it is believed that a genetic abnormality may be leading to these cases: mutation of the Cx43 gene. Diagnosis of the case concerned was given by transthoracic echocardiography and computed CT of the aorta and pulmonary arteries, which showed, in addition to the criss-cross heart, other abnormalities, such as double-outlet RV, large ASD and ventricular septal defect (VSD).(AU)

Results of percutaneous closure with device in congenital heart disease of the atrial septal defect type / Resultados del cierre percutáneo con dispositivo en la cardiopatía congénita de tipo comunicación interauricular

Congenital Interatrial Septal Defects (TEA) are among the most common Congenital Heart Diseases in the population, where Atrial Septal Defect stands out, which is produced by a left-right short circuit that provides greater survival and less morbidity and mortality. The objective was to determine the results of Percutaneous Closure with a Device in Congenital Heart Disease of the Atrial Communication type at the Carlos Andrade Marín Specialty Hospital (Quito) in the Hemodynamics service from January 2009 to July 2019. It is a retrospective descriptive cross-sectional study . With a population of 122 cases from the AS400 registry. Thus, it was determined: there is a female predominance in a ratio of 2:1, the ranges for defect intervention were 5.5 mm to 35 mm, post-procedure pulmonary artery pressures (systolic 18-25 mmHg and diastolic 6-10 mmHg) in 95% of patients, ventricular overload in 76% in pre-procedure patients. Concluding that 96% of our population has a significant post-procedure improvement.

Efficacy of fenestrated atrial septal defect occulders on pulmonary hypertension dogs / 中华心血管病杂志

Objective: To explore the short-term efficacy of fenestrated atrial septal defect (ASD) occulders in the treatment of pulmonary arterial hypertension (PAH). Methods: Thirty-six healthy dogs were divided into the balloon atrial septostomy (BAS)+fenestrated ASD occulders group (n=12), BAS group (n=12) and non-septostomy group (n=12). PAH was induced by intra-atrial injection of dehydrogenized monocrotaline (1.5 mg/kg) in all dogs. Animals in the BAS+fenestrated ASD occulders group underwent atrial septal puncture and fenestrated ASD occulders implantation. Animals in the BAS group underwent balloon atrial septostomy. The non-septostomy group received no surgical intervention. The hemodynamic indexes and blood N-terminal pro-B-type natriuretic peptide (NT-proBNP) of dogs were measured before modeling, 2 months after modeling, 1, 3, and 6 months after surgery, respectively. Echocardiography was performed to observe the patency of the shunt and atrial septostomy of the dogs in the BAS+fenestrated ASD occulders group and BAS group at 1, 3, and 6 months after surgery. Three dogs were sacrificed in each group at 1, 3, and 6 months after surgery, respectively. Atrial septal tissue and fenestrated ASD occulders were removed to observe the patency and endothelialization of the device. Lung tissues were obtained for hematoxylin-eosin (HE) staining to observe the inflammatory cells infiltration and the thickening and narrowing of the pulmonary arterials. Results: Among 36 dogs, 2 dogs died within 24 hours after modeling, and 34 dogs were assigned to BAS+fenestrated ASD occulders group (n=12), BAS group (n=11), and non-septostomy group (n=11). Compared with BAS group, the average right atrial pressure (mRAP) and NT-proBNP of dogs in the BAS+fenestrated ASD occulders group were significantly reduced at 3 months after surgery (P<0.05), and the cardiac output (CO) was significantly increased at 6 months after surgery, arterial oxygen saturation (SaO2) was also significantly reduced (P<0.05). Compared with non-septostomy group, dogs in the BAS+fenestrated ASD occulders group had significantly lower mRAP and NT-proBNP at 1, 3, and 6 months after surgery (P<0.05), and higher CO and lower SaO2 at 6 months after surgery (P<0.05). Compared with the non-septostomy group, the dogs in the BAS group had significantly lower mRAP and NT-proBNP at 1 month after surgery (P<0.05), and there was no significant difference on mRAP and NT-proBNP at 3 and 6 months after surgery (P>0.05). Echocardiography showed that there was a minimal right-to-left shunt in the atrial septum in the BAS group at 1 month after the surgery, and the ostomy was closed in all the dogs in the BAS group at 3 months after the surgery. There was still a clear right-to-left shunt in the dogs of BAS+fenestrated ASD occulders group. The shunt was well formed and satisfactory endothelialization was observed at 1, 3 and 6 months after surgery. The results of HE staining showed that the pulmonary arterials were significantly thickened, stenosis and collapse occurred in the non-septostomy group. Pulmonary microvascular stenosis and inflammatory cell infiltration in the pulmonary arterials were observed in the non-septostomy group. Pulmonary arterial histological results were comparable between BAS+fenestrated ASD occulders group and non-septostomy group at 6 months after surgery . Conclusions: The fenestrated ASD occulder has the advantage of maintaining the open fistula hole for a longer time compared with simple balloon dilation. The fenestrated ASD occulder can improve cardiac function, and it is safe and feasible to treat PAH in this animal model.

Complicaciones a corto plazo del cierre percutáneo de comunicación interauricular / Short-term complications of percutaneous atrial septal defect closure

Resumen Introducción: El cierre percutáneo de la comunicación interauricular ostium secundum ha pasado a ser una alternativa a la cirugía convencional. En ese caso, los dispositivos de autocentrado son los más usados entre los cardiólogos intervencionistas. El tipo y la tasa de complicaciones difieren para los distintos dispositivos. Objetivo: Reportar las complicaciones a corto plazo del cierre percutáneo de la comunicación interauricular ostium secundum. Método: Entre abril de 2001 y diciembre de 2017, 129 pacientes (media de edad: 26 años; desviación estándar: 20,39 años) fueron sometidos a cierre percutáneo de comunicación interauricular ostium secundum. Las complicaciones fueron identificadas y clasificadas como mayores y menores. Resultados: 14 pacientes experimentaron complicaciones menores durante la hospitalización y en el primer año de seguimiento (10.85 %), y uno tuvo una complicación mayor que requirió cirugía electiva 4 meses después para la remoción del dispositivo mal posicionado. Entre los que presentaron complicaciones menores, dos tuvieron shunt residual leve, cinco presentaron arritmias interoperatorias, uno refirió dolor torácico y seis tuvieron migraña posimplante. Conclusiones: Esta serie de pacientes muestra que el cierre percutáneo de la comunicación interauricular ostium secundum es un procedimiento seguro y efectivo en casos bien seleccionados. Con el fin de reducir la tasa de complicaciones, están indicados el diagnóstico y el tratamiento tempranos, así como la observación de los criterios de selección de acuerdo con la morfología de la comunicación interauricular ostium secundum. La profilaxis antiagregante con clopidogrel para todos los pacientes requiere mayor investigación.

Abstract Introduction: Percutaneous closure of ostium secundum atrial septal defects has become an alternative to conventional surgery. Self-centering devices are the ones most used by interventional cardiologists in these cases. The type and rate of complications varies according to the various devices. Objective: To report the short-term complications of percutaneous closure of ostium secundum atrial septal defects. Method: Between April 2001 and December 2017, 129 patients (mean age: 26; standard deviation: 20.39 years) underwent percutaneous closure of ostium secundum atrial septal defects. Complications were identified and classified as major or minor. Two types of devices were used: the Amplatzer™ Septal Occluder in 98 patients, and the Figulla® Septal Occluder in 31 patients. Results: 14 patients had minor complications during hospitalization and the first year of follow up (10.85%), and one had a major complication which required elective surgery four months later to remove the misaligned device. Of those who experienced minor complications, two had mild residual shunting, five had intraoperative arrhythmias, one reported chest pain, and six had post-implant migraines. Conclusions: This series of patients shows that percutaneous closure of ostium secundum atrial septal defects is a safe and effective procedure in carefully selected cases. Early diagnosis and treatment are needed to decrease the rate of complications, along with adherence to the selection criteria according to the morphology of the ostium secundum atrial septal defect. Antiplatelet prophylaxis with clopidogrel for all patients requires further study.

Atrial Septal Aneurysm and Atrial Septal Defect Association - an Uncommon But Well-Recognized Association

Abstract Atrial septal aneurysm (ASA) is an uncommon but well-recognized cardiac abnormality. This educational text reviews the case of a 54-year-old female presenting an ASA related to a small ostium secundum atrial septal defect. The considerable signs and symptoms, interestingly, have not been justified by the clinical and hemodynamic investigations. So, we opted for a better imaging investigation with cardiac catheterization and transesophageal echocardiography. The surgical process was earlier indicated and performed with aid of cardiopulmonary bypass.

Efficacy and safety of a parylene-coated occluder for atrial septal defect: a prospective, multi-center, randomized controlled clinical trial / 中华医学杂志(英文版)

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.

Feasibility and safety of intracardiac ultrasound-assisted atrial septal puncture during radiofrequency ablation for atrial fibrillation / 中华心血管病杂志

Objective: To explore the feasibility and safety of intracardiac ultrasound-assisted atrial septal puncture (ASP) during radiofrequency ablation for atrial fibrillation. Methods: We enrolled 241 consecutive patients scheduled to radiofrequency ablation for atrial fibrillation in Beijing Anzhen Hospital from July to September 2020. Inclusion criteria: patients aged over 18 years with a clear electrocardiogram record of atrial fibrillation. Patients were divided into 2 groups: ASP with ultrasound-assisted X-ray (ultrasound group, n=123), ASP under X-ray alone (X-ray group, n=118). Clinical features of patients including age, sex, percent of paroxysmal atrial fibrillation, and repeat ablation, CHA2DS2-VASc score and past history (hypertension, diabetes mellitus, coronary artery disease, stroke/transient ischemic attack (TIA), valve diseases) and echocardiographic parameters (left atrial dimension, left ventricular ejection fraction, left ventricular end-diastolic dimension) were obtained and compared. The first-pass rate, radiation exposure time, duration of ASP, and complications of ASP were also compared between the two groups. Results: The age of patients in this cohort was (62.5±8.0) years, and the proportion of males was 57.0% (n=138). Among them, the proportion of paroxysmal atrial fibrillation was 56.0% (n=135), and the ratio of repeat ablation was 17.8% (n=43). Age, sex, percent of paroxysmal atrial fibrillation, history of hypertension, diabetes mellitus were similar between the two groups. The first-pass rate was significantly higher in the ultrasound group than in the X-ray group (94.3% (116/123) vs. 79.7% (94/118), P=0.001); the exposure time of X-ray was significantly shorter in the ultrasound group than in the X-ray group ((31.3±7.9) s vs. (124.8±35.7) s, P<0.001), while the duration of ASP was longer in the ultrasound group ((10.1±1.8) minutes vs. (8.2±1.3) minutes, P<0.001). In terms of complications, the incidence of puncture into the pericardium was lower in the ultrasound group (0 vs.3.4% (4/118), P=0.039); the rate of transient ST-segment elevation post ASP was similar between the ultrasound group and X-ray group (2.4% (3/123) vs. 1.7% (2/118), P=0.999). Conclusion: Intracardiac ultrasound-assisted atrial septal puncture can effectively improve the accuracy of atrial septal puncture, shorten the radiation exposure time, and reduce the complications related to atrial septal puncture.

Cor triatriatum dexter y comunicación interauricular tipo seno venoso: Una asociación infrecuente / Cor triatriatum dexter and sinus venosus atrial septal defect: An infrequent association

RESUMEN El cor triatriatum es una malformación congénita poco frecuente, con una prevalecia de un 0,1% entre todas las anomalías congénitas cardíacas, donde el corazón queda dividido en tres atrios o aurículas. En el cor triatriatum dexter la aurícula derecha queda dividida, por una membrana fibromuscular, en dos partes, una proximal y otra distal, que se comunican o no entre sí. En la evolución natural de la enfemedad, los pacientes pueden permanecer asintomáticos hasta su diagnóstico o presentar manifectaciones cardiovasculares secundarias a insuficiencia cardíaca derecha y trastornos del ritmo. En el caso particular de aquellos que se encontraran sintomáticos, el tratamiento de elección sería la corrección quirúrgica del defecto y, en ocasiones, la rotura percutánea de la membrana; mientras que en los que se encuentran asintomáticos, el seguimiento y tratamiento oportuno de sus complicaciones parecería la alternativa más viable.

ABSTRACT Cor triatriatum is a rare congenital condition with a 0.1% prevalence among all cardiac congenital anomalies in which the heart is partitioned into three atria. In cor triatriatum dexter the right atrium is divided by a fibromuscular membrane into two parts, a proximal and a distal one, which may or may not communicate with each other. In the natural course of the condition, patients may remain asymptomatic until diagnosis or present with cardiovascular manifestations secondary to right heart failure and rhythm disorders. In the specific case of symptomatic patients, the treatment of choice would be surgical correction of the anomaly and sometimes percutaneous rupture of the membrane; while in asymptomatic patients, timely follow-up and treatment of their complications would seem to be the best alternatives.

Comparison of postoperative changes in inflammatory marker levels between transthoracic and transcatheter device closures of atrial septal defects in children

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.
