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

Introdução: A ecocardiografia é uma ferramenta diagnóstica de crescente utilização na prática clínica, aplicada a diversos cenários médicos. Os cuidados e os processos de manutenção preventiva ou corretiva dos equipamentos são ainda pouco padronizados. O objetivo do presente estudo foi descrever o processo de manutenção atualmente aplicado a equipamentos ecocardiográficos em um laboratório. Descrever o processo inclui a caracterização de danos e aplicações de manutenção preventiva ou corretiva. Métodos: Estudo observacional descritivo e exploratório realizado em centro único. As informações de dados do processo de manutenção de equipamentos ecocardiográficos foram obtidas de arquivos eletrônicos do sistema de gestão de equipamentos de um laboratório de médio porte de um hospital público de nível terciário com características de ensino, no período de 2003 a 2018. Resultados: Foram identificados dez tipos de avarias mais comuns, como dano a programas (23,8%), peças (23,1%) e relacionadas à queda de energia e de acessórios (13,8%). Após a implementação do processo de manutenção preventiva, houve significativa redução dos custos de manutenções (US$ 44.472,10 versus US$ 25.807,59; p= 0,029). Mesmo após a manutenção preventiva, os custos de manutenção corretiva em equipamentos aplicados à ecocardiografia transesofágica (US$ 7.789,17) foram maiores que aqueles a equipamentos aplicados a outras modalidades (US$ 3.184,37 em ecocardiografia transtorácica e US$1.813,00 em estresse). Conclusão: O processo de manutenção de equipamentos ecocardiográficos foi descrito. Danos a equipamentos ecocardiográficos estão relacionados a altos custos, principalmente naqueles aplicados a modalidades especiais, como ecocardiografia transesofágica. As manutenções preventivas reduziram significativamente os custos de manutenção. (AU)


Introduction: Echocardiography is a diagnostic tool that is increasingly used in clinical practice in different medical scenarios; however, the preventive (PM) or corrective maintenance (CM) care and processes for this equipment are still poorly standardized. To describe the maintenance process currently implemented for echocardiographic equipment (ECHO) in a medium-sized laboratory in a tertiary-level public teaching hospital. The description of the process includes damage characterization and MP and MC implementation. Methods: This was a descriptive and exploratory single-center observational study. Data on the maintenance process of echocardiographic equipment were obtained from electronic files from the hospital's equipment management system between 2003 and 2018. Results: Together with the description of the equipment maintenance process, the ten most common types of malfunctions were identified, including software (23.8%), parts (23.1%), and power outage and accessory damage (13.8%). The implementation of the PM process significantly decreased the maintenance costs (USD 44,472.10 vs USD 25,807.59, p = 0.029). Even after the MP, the CM costs related to transesophageal echocardiography equipment (TEE) (USD 7,789.17) were higher than those with other equipment modalities (USD 3,184.37 for transthoracic echocardiography equipment (TTE) and USD 1,813.00 for stress testing). Conclusion: The maintenance process for ECHO equipment was described. ECHO equipment damage has high costs, especially in special modalities such as TEE. PM significantly reduced maintenance costs.

ABSTRACT

La disfunción valvular protésica es cada vez más frecuente debido al envejecimiento de la población portadora de bioprótesis y se presenta como un desafío en el momento de su diagnóstico, valoración y tratamiento. Aplicar un enfoque imagenológico multimodal es fundamental para su manejo. Respecto al tratamiento, surge como nueva alternativa un procedimiento mínimamente invasivo de sustitución valvular percutánea, denominado valve in valve, principalmente en pacientes con riesgo quirúrgico elevado. Presentamos uno de los primeros casos locales de implante percutáneo de prótesis mitral transeptal dentro de una bioprótesis mitral quirúrgica disfuncionante.


Prosthetic valve dysfunction is increasingly common due to the aging of the bioprosthesis-bearing population, and it presents a challenge at the time of diagnosis, evaluation, and treatment. A multimodal imaging approach is essential for its management. In relation to treatment, a minimally invasive percutaneous valve replacement procedure called valve in valve arises as a new alternative, mainly in patients with high surgical risk. We present one of first local cases of percutaneous implantation of a transseptal mitral prosthesis within a dysfunctional surgical mitral bioprosthesis.

ABSTRACT

O sinal RAC (retroaortic anomalous coronary ou artéria coronária anômala retroaórtica) é um achado desconhecido, descrito ao ecocardiograma transtorácico como uma estrutura tubular ecogênica, localizada na face atrial do sulco atrioventricular. Apresentamos um caso onde o sinal RAC se apresenta na ecocardiografia transesofágica (ETE). O conhecimento do sinal RAC e a avaliação com ETE aumentam a sensibilidade e a especificidade e conferem a oportunidade de avaliar características anatômicas de alto risco, importantes na avaliação do risco de morte súbita.(AU)

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

Abstract Objective: To examine the relationship between the left atrial (LA) thrombus presence and the epicardial adipose tissue (EAT) thickness. Methods: Three hundred and twelve consecutive rheumatic mitral valve stenosis (RMVS) patients with mitral valve area (MVA) < 2 cm2 were included in this cross-sectional study. Patients were divided into two groups, those with and those without LA thrombus. Routine biochemical analysis and electrocardiographic examinations were carried out. EAT was measured using transthoracic echocardiography. Results: LA thrombus was determined in 84 (26.9%) RMVS patients. In echocardiographic examinations, higher mean gradient and LA diameter as well as lower MVA were found in the group with LA thrombus (P<0.001). In this group, higher C-reactive protein (CRP) and EAT values were also determined (P<0.001). There was significant correlation between EAT and MVA, CRP, LA appendage peak flow velocity, LA anteroposterior diameter, and mean gradient (P<0.001). Higher EAT values were identified as independently associated with the presence of LA thrombus (odds ratio 59.5; 95% confidence interval 12.1-290.10; P<0.001). Conclusion: Transthoracic echocardiography, routinely used in patients with RMVS, can measure EAT to determine patients who are under risk for thrombus.

ABSTRACT

Abstract Background: Paravalvular leak (PVL) is a frequent and important complication after surgical valvular replacement that can cause heart failure and hemolytic anemia and is associated with poor clinical outcomes. Surgical reoperation has been the standard treatment, but it is associated with high morbidity and mortality. Transcatheter closure is a therapeutic alternative. The aim of the present study is to analyze the feasibility and the short- and medium-term outcomes of the transcatheter closure of PVLs. Methods: Single-center registry of consecutive patients with post-surgical PVLs that underwent transcatheter closure, between January 2006 and December 2016. Efficacy and safety results were analyzed during the procedure and at 6-month follow-up. Results: Twenty-one PVLs (15 mitral, 5 aortic, and 1 tricuspid) were closure during 20 procedures. In the initial echocardiography, 91% of the leaks were severe. The most used device was the Amplatzer Vascular Plug III® in 10 procedures (50%). The three-dimensional transesophageal echocardiography was used in 70% of cases. The device was successfully implanted in 95% of cases, a regurgitation reduction ≥ 1 grade was achieved in 95% of the cases, and the clinical success was 79%. Six-month survival was 100%; however, three cases required valvular surgery (15%). Conclusions: Transcatheter closure of PVLs is a feasible and safe procedure with high rates of technical, echocardiographic, and clinical success in the short and medium term. It is an adequate therapeutic alternative, mainly in high surgical risk patients and multiples comorbidities.


Resumen Introducción: La fuga paravalvular es una complicación frecuente e importante posterior al reemplazo valvular quirúrgico que puede ocasionar insuficiencia cardiaca, anemia hemolítica y se relaciona con malos resultados clínicos. La reintervención quirúrgica ha sido el tratamiento habitual, pero se acompaña de alta morbimortalidad. El cierre transcatéter es una alternativa terapéutica. El objetivo del presente estudio es analizar la factibilidad y los resultados a corto y mediano plazo del cierre transcatéter de fugas paravalvulares con dispositivos oclusores. Métodos: Registro unicéntrico de una serie consecutiva de pacientes con fugas paravalvulares posquirúrgicas que fueron cerradas vía transcatéter con dispositivos oclusores, entre enero del 2006 y diciembre del 2016. Se analizaron los resultados de eficacia y seguridad durante el procedimiento y a seis meses. Resultados: Se trataron 21 fugas paravalvulares (15 mitrales, 5 aórticas y 1 tricuspídea) durante 20 procedimientos. El 91% de las fugas fue grave en la ecocardiografía inicial. El dispositivo utilizado con más frecuencia fue el Amplatzer Vascular Plug III® en 10 procedimientos (50%). Se utilizó ecocardiografía transesofágica tridimensional en 70% de los casos. Se logró implantar el dispositivo con éxito en el 95% de los casos; se consiguió una reducción ≥ 1 del grado de regurgitación en el 95% de las veces y se alcanzó el éxito clínico en el 79%. A seis meses la supervivencia fue del 100%; sin embargo, tres casos requirieron cirugía valvular (15%). Conclusiones: El cierre transcatéter de fugas paravalvulares es un procedimiento factible, seguro y con tasas elevadas de éxito técnico, ecocardiográfico y clínico a corto y mediano plazo. Es una alternativa terapéutica adecuada, en particular en pacientes considerados de alto riesgo quirúrgico y múltiples comorbilidades.

ABSTRACT

Abstract Background: Veno-venous extracorporeal membrane oxygenation is an established therapy for patients with refractory acute respiratory distress syndrome (ARDS). One complication related to the use of veno-venous extracorporeal membrane oxygenation is thrombosis despite proper anticoagulation. We report the diagnosis and management of a clot-obstruction in a single site cannula placed through the internal jugular vein, guided by transesophageal echocardiography. Case report: A 39 year-old male developed acute respiratory distress syndrome and hemodynamic instability after an episode of pulmonary aspiration in the ICU. Eight hours after placement of a single site veno-venous extracorporeal membrane oxygenation, suddenly the perfusionist noticed a reduction in flow. TEE showed a thrombus-like mass obstructing the inflow port in SVC and inflow at IVC was intact. After unsuccessful attempts to reposition the cannula, the team decided to insert additional femoral inflow cannula through the IVC. The single site catheter was then pulled out until its tip was positioned in the right atrium and all three ports of the catheter were switched to the infusion ports. After this, flows and oxygenation improved significantly. Unfortunately, despite all of the efforts, the patient died 2 days later. Discussion: The diagnosis of veno-venous extracorporeal membrane oxygenation cannula obstruction is based on reduced inflow rates, hemodynamic instability and poor oxygenation of blood. TEE allows evaluation of the flows inside the cannula and in this case, an obstruction was found. The management presented points to the fact that in a situation of catheter obstruction caused by a clot, there is a feasible alternative to assure minimal interruption of the hemodynamic support offered by the veno-venous extracorporeal membrane oxygenation.


Resumo Justificativa: A oxigenação por membrana extracorpórea veno-venosa é terapia estabelecida para pacientes com a síndrome do desconforto respiratório agudo. Uma complicação relacionada ao uso da oxigenação por membrana extracorpórea veno-venosa é trombose apesar de anti-coagulação adequada. Relatamos o diagnóstico e conduta em obstrução por coágulo em cânula de acesso único inserida pela veia jugular interna, guiada por ecocardiografia transesofageana. Relato de caso: Paciente do sexo masculino de 39 anos desenvolveu síndrome do desconforto respiratório agudo e instabilidade hemodinâmica após episódio de aspiração pulmonar na UTI. Oito horas após a instalação de oxigenação por membrana extracorpórea veno-venosa de acesso único, o perfusionista notou repentina redução no fluxo. A ETE revelou massa semelhante a um trombo obstruindo o portal de fluxo de entrada na VCS e o fluxo de saída na VCI estava intacto. Após tentativas sem sucesso para reposicionar a cânula, a equipe decidiu inserir cânula de entrada de fluxo adicional pela VCI. O catéter de acesso único foi, então, puxado até que sua ponta se posicionasse no átrio direito e todos os três portais do catéter fossem transferidos para os portais de infusão. A seguir, os fluxos e oxigenação melhoraram significativamente. Infelizmente, apesar dos esforços, o paciente foi a óbito 2 dias depois. Discussão: O diagnóstico de obstrução de cânula da oxigenação por membrana extracorpórea veno-venosa se baseia em velocidades reduzidas de entrada de fluxo, instabilidade hemodinâmica e oxigenação pobre do sangue. A ETE permite a avaliação dos fluxos dentro da cânula, e nesse caso foi encontrada obstrução. A técnica apresentada aponta para o fato de que em situação de obstrução de catéter causada por coágulo, existe alternativa factível para garantir interrrupção mínima do suporte hemodinâmico oferecido pela oxigenação por membrana extracorpórea veno-venosa.

ABSTRACT

Patent foramen ovale (PFO) is a prevalent congenital septal atrial defect usually without pathological significance. In certain pathogenic situations, PFO can trigger episodes of recurrent hypoxemia, a specific condition known as platipnea-orthodeoxia syndrome (POS). We report a 73 years old female presenting with dyspnea and low arterial oxygen saturation. On admission the patient had a hemoglobin saturation of 81% and an arterial oxygen partial pressure of 50 mmHg. After breathing 100% a 17% arterial-venous shunt was found (normal: less than 12%). A transesophageal echocardiogram and a cardiac catheterization showed the presence of a PFO. A percutaneous closure was performed.

ABSTRACT

Nas últimas décadas, o aumento das indicações para dispositivos cardíacos eletrônicos implantáveis tem sido acompanhado pela elevação dos casos de complicações relacionadas ao seu uso, dentre elas a endocardite infecciosa. Apesar dos avanços diagnósticos e terapêuticos da doença, esta mantém elevada morbimortalidade. Os casos relacionados aos dispositivos apresentam importantes limitações referentes aos critérios e aos métodos diagnósticos que implicam na tomada de decisão terapêutica sobre retirada do dispositivo, com risco de morte e outras complicações. Ainda assim, o ecocardiograma mantém um grande valor no diagnóstico da endocardite infecciosa relacionada a dispositivos cardíacos e de suas complicações. O entendimento das limitações e dos desafios acerca do diagnóstico reforça a necessidade de mais estudos sobre do tema. O presente artigo visa descrever a epidemiologia, a microbiologia, os fatores de risco, a patogenia, o diagnóstico e o tratamento da endocardite infecciosa associada aos dispositivos cardíacos eletrônicos implantáveis, visando demonstrar, principalmente, o valor dos exames de imagem na abordagem dessa condição clínica, com ênfase nos achados ao ecocardiograma.


In recent decades, the increase in indications for implantable electronic cardiac devices has been accompanied by an increase in cases of complications related to their use, including infectious endocarditis. Despite the diagnostic and therapeutic advances of the disease, it maintains high morbidity and mortality. The cases related to the devices have important limitations regarding the criteria and diagnostic methods that imply in making a therapeutic decision about removing the device, with risk of death and other complications. Still, echocardiography remains of great value in the diagnosis of infective endocarditis related to cardiac devices and their complications. Understanding the limitations and challenges regarding diagnosis reinforces the need for further studies on the topic. This article aims to describe the epidemiology, microbiology, risk factors, pathogenesis, diagnosis and treatment of infective endocarditis associated with implantable electronic cardiac devices, aiming to demonstrate, mainly, the value of imaging tests in addressing this clinical condition , with emphasis on echocardiogram findings.

ABSTRACT

Abstract Objective: To evaluate the changes of the mitral valve geometrics and the degrees of moderate mitral regurgitation (MR) in patients undergoing aortic valve replacement (AVR) for aortic stenosis (AS). Methods: A retrospective analysis study of intraoperative transesophageal echocardiography (TEE) and postoperative transthoracic echocardiography (TTE) was performed in 49 patients diagnosed with pure AS combined with moderate MR, who underwent AVR from January 2013 to December 2017. TEE was used to evaluate the direct geometric changes of the mechanical effects on mitral annulus after AVR. TTE was used to evaluate the changes of MR after operation. All patients underwent TTE during the midterm follow-up. The mean follow-up time was 40.21 months. Results: All of the 49 patients had moderate MR. Anterolateral-posteromedial diameter, anterior-posterior diameter, and mitral annular area were significantly reduced after AVR, while no significant changes were found in the intraoperative left ventricular loading conditions before and after AVR. The degree of mitral valve regurgitation, left ventricular size, left atrial size, left ventricular end-diastolic volume, and left ventricular to aortic pressure gradient were significantly reduced before discharge, and midterm follow-up showed good results. Conclusion: This study supports the belief that aortic outflow tract obstruction and an actual mechanical compression of the anterior mitral annulus after AVR would cause reduction in MR. Ventricular remodeling would also cause reduction in MR with time going on. Patients with AS, especially young patients with moderate MR, were most likely to benefit from AVR in early time.
