ABSTRACT

Abstract Background: Overweight and obesity (O/O) generate lipotoxicity of the cardiac fiber and increase the incidence and progression of aortic valve stenosis. The low cardiac output syndrome (LCOS) is a timing complication after to aortic valve replacement (AVR) surgery. Objective: The objective of the study was to investigate if body mass index (BMI) kg/m2 is a risk factor associated with LCOS and mortality in the post-operative period of AVR. Methods: A historic cohort study was designed, including patients with severe aortic stenosis (SAS), who were subjected to AVR. Results: 152 patients were included, 45 (29.6%), with normal weight (NW), 60 were overweight (39.5%), and 47 obese (30.9%). The prevalence of systemic hypertension (HT) was higher in O/O (p < 0.0001). Incidence of LCOS was 44.7%, being more frequent in the O/O groups compared to the NW group, 43.3%, 68.1%, and 22.2%, respectively, (p < 0.05 in overweight and p < 0.0001 in the obese). Assessing the presence or absence of LCOS associated with BMI as a numerical variable, we found that women, HT, BMI, left ventricular mass, and valve size, were associated with LCOS (p < 0.02, p < 0.02, p < 0.001, p < 0.032, and p < 0.045, respectively). Mortality was higher in patients who had LCOS (p < 0.02). Multivariate model showed that BMI was an independent risk factor for LCOS (odds ratio [OR] 1.21 [95% CI 1.08-1.35], p < 0.001). Conclusion: BMI is a risk factor associated to LCOS in the post-operative period of AVR in patients with SAS.


Resumen Antecedentes: El sobrepeso y la obesidad (O/O) generan lipotoxicidad de la fibra cardíaca y aumentan la incidencia y progresión de la estenosis de la válvula aórtica. El síndrome de bajo gasto cardíaco (SBGC) es una complicación postquirúrgica de la cirugía de reemplazo de válvula aórtica (RVA). Objetivo: Investigar si el índice de masa corporal kg/m2 (IMC) es un factor de riesgo asociado con SBGC y mortalidad en el postoperatorio de RVA. Métodos: Se diseñó un estudio de cohorte histórico, que incluyó pacientes con estenosis aórtica importante (EAI), que fueron sometidos a RVA. Resultados: Se incluyeron 152 pacientes, 45 (29.6%), con peso normal (N), 60 tenían sobrepeso (39.5%) y 47 obesos (30.9%). La prevalencia de hipertensión sistémica (HT) fue mayor en O/O (p < 0.0001). La incidencia de SBGC fue del 44.7%, siendo más frecuente en los grupos O/O en comparación con el grupo N, 43.3%, 68.1%, 22.2% respectivamente, (p < 0.05 en sobrepeso y p < 0.0001 en obesos). Al evaluar la presencia o ausencia de SBGC asociado con el IMC como una variable numérica, encontramos que las mujeres, HT, IMC, masa ventricular izquierda y tamaño de la válvula, se asociaron con SBGC (p < 0.02, p < 0.02, p < 0.001, p < 0.032, p < 0.045, respectivamente). La mortalidad fue mayor en pacientes con SBGC (p < 0.02). El modelo multivariado mostró que el IMC fue un factor de riesgo independiente asociado a SBGC [OR 1.21 (IC 95% 1.08-1.35), p < 0.001]. Conclusión: El IMC es un factor de riesgo asociado a SBGC en el postoperatorio de RVA en pacientes con EAI.

ABSTRACT

Resumen Los pacientes con cardiopatías congénitas que afectan la continuidad del ventrículo derecho con la arteria pulmonar deben someterse con frecuencia a intervenciones debido a la limitada vida útil de los conductos quirúrgicos, lo que lleva al desarrollo de disfunción ventricular derecha por cambios en la geometría ventricular y predisposición a arritmias letales, con el consiguiente riesgo de reintervenciones. El implante valvular percutáneo pulmonar es una nueva alternativa terapéutica, menos invasiva en comparación con la quirúrgica, para pacientes seleccionados. Se realiza una revisión de las publicaciones médicas actuales disponibles y se describe la experiencia inicial del implante valvular pulmonar percutáneo en un centro colombiano de alta complejidad para el tratamiento de enfermedades cardiovasculares, en dos pacientes con disfunción del homoinjerto aórtico en posición pulmonar con doble lesión valvular, en los cuales el implante valvular pulmonar percutáneo fue una conducta exitosa. Se eligió a pacientes con cardiopatías congénitas, conductos quirúrgicos disfuncionales con estenosis o insuficiencia pulmonar significativa, y disfunción y dilatación ventricular derechas. Se empleó la técnica regular para el implante de la válvula pulmonar Melody, sin documentarse complicaciones durante el procedimiento ni al año de seguimiento. El implante percutáneo de la válvula pulmonar es un gran avance en el tratamiento de pacientes con cardiopatías congénitas, con resultados favorables a corto y mediano plazos, lo cual hace posible la restauración de la función ventricular con riesgo mínimo, frente al reemplazo quirúrgico en pacientes seleccionados.


Abstract Patients with congenital heart disease that involves reconstruction of the right ventricular outflow tract must frequently undergo interventions derived from the limited useful life of the surgical canals, which leads to the development of right ventricular dysfunction due to changes in the ventricular geometry and predisposition to lethal arrhythmias, with the consequent risk of reinterventions. The percutaneous pulmonary valvular implant is a new therapeutic alternative, less invasive, compared to surgery, for selected patients. A review of the available literature is made and the initial experience of percutaneous pulmonary valve implantation in a Colombian center of high complexity for the treatment of cardiovascular diseases is described, in two patients with aortic homograft dysfunction in a pulmonary position with double valvular lesion, in which the percutaneous pulmonary valve implant was a successful strategy. Patients with congenital heart disease were chosen, with dysfunctional surgical conduits with stenosis or significant pulmonary insufficiency, with dysfunction and right ventricular dilatation. The standard technique for the implantation of the Melody pulmonary valve was used, without complications during the procedure or one year of follow-up. Percutaneous implantation of the pulmonary valve is a great advance in the management of patients with congenital heart diseases, with favorable results in the short and medium term, allowing the restoration of ventricular function with minimal risk, compared to surgical replacement in selected patients.

ABSTRACT

ANTECEDENTES: El reemplazo protésico de la válvula tricúspide es un procedimiento infrecuente, con elevada mortalidad y morbilidad operatoria, independientemente de la etiología de la insuficiencia tricuspídea. Persiste aún una discusión respecto al tipo de prótesis a utilizar, mecánica o biológica. OBJETIVO: Analizar nuestros resultados perioperatorios y alejados en el reemplazo valvular tricuspídeo, comparando ambos tipos de prótesis. MÉTODO: Revisión de la Base de Datos de nuestro Servicio de Cirugía Cardiovascular para el periodo enero 1991 - diciembre 2017. Identificados los pacientes con reemplazo valvular tricuspídeo (RVT); se revisaron los protocolos operatorios y los ecocardiogramas. La supervivencia se certificó a través del Registro Civil e Identificación de Chile. RESULTADOS: Se identificaron 83 pacientes con RVT (76% mujeres), los que representaron el 0,7% del total de las cirugías con circulación extracorpórea y el 2,1% de las cirugías valvulares para el periodo en estudio. La edad promedio fue 49±16,5 años. Cuarenta y nueve casos (59%) correspondieron a reoperaciones y otros 49 tuvieron un procedimiento asociado. En 40 pacientes (48%) se utilizó una prótesis mecánica y en 43 (52%) una biológica. La mortalidad operatoria global fue 9,6% (8 pacientes, 4 con una prótesis mecánica y 4 con una biológica). El seguimiento se completó en el 100%, con un promedio de 7,1 años. Veintiocho pacientes fallecieron durante el seguimiento; la principal causa fue insuficiencia cardiaca. Así, la supervivencia a 5 años fue 70,3 ± 5,3% y a 10 años 58 ± 6,3%, sin diferencia significativa entre ambos tipos de prótesis. Siete pacientes se reoperaron durante el seguimiento (5 casos con prótesis biológica y 2 mecánica). CONCLUSIÓN: El RVT continúa siendo un procedimiento infrecuente, con mayor incidencia en mujeres, en la quinta década de la vida. La mayoría de los pacientes presentaba comorbilidad y había tenido cirugía cardiovascular previa. La mitad de estos recibió una prótesis mecánica y la otra, biológica. No hubo diferencias significativas entre ambos tipos de prótesis en cuanto a mortalidad operatoria, supervivencia alejada o reoperación.


BACKGROUND: Tricuspid valve replacement (TVR) is an uncommon surgical procedure, associated with high mortality and morbidity. The use of biological or mechanical prostheses in TVR has advantages and disadvantages and, therefore, there persists a debate regarding the choice of one or other type of prostheses. AIM: To analyze our operative and long-term surgical results, comparing both types of prosthetic valves. METHODS: The Data Base of the Cardiovascular Surgery Service was reviewed for the period between January 1991 and December 2017. 83 patients with TVR were identified, the operative notes and echocardiogram reports were analyzed. Survival was obtained from the Chilean Civil Identification Service. RESULTS: 83 patients (76% women) had TVR. They represented 0.7% of the total cases operated on with extracorporeal circulation and 2.1% of all valve disease cases, for the study period. Mean age was 49±16.5 years. 49 cases (59%) were reoperations and another 49 had an associated procedure. In 40 patients (48%) a mechanical prosthesis was used and in 43 (52%) a biological one was implanted. Operative mortality rate was 9.6% (8 patients, had a mechanical valve and the other 8, a biological one). Follow-up was 100% completed, with an average of 7.1 years. 28 patients died during follow-up; the main cause of death was heart failure. Five-year survival rate was 70.3 ± 5.3% and at 10 years it was 58 ± 6.3%, without significant difference the type of prostheses. Seven patients were re-operated during follow-up (5 cases corresponded to a biological prostheses and 2 to a mechanical one). CONCLUSION: TVR is still an infrequent surgical procedure, more commonly performed in women, on the fifth decade of life. Most patients presented comorbidities and had a previous cardiovascular surgical operation. Half of them received a mechanical prosthesis and half a biological one. There was no significant difference between both types of prostheses related to surgical mortality, long-term survival or reoperation.

ABSTRACT

Abstract Background: Prosthesis-patient mismatch (PPM) is associated with worse outcomes. Objective: Determine the frequency and evaluate preoperatory variables independently associated with severe PPM in a tertiary hospital focused on Public Health Care. Methods: A total of 316 patients submitted to aortic valve replacement, who had echocardiography performed within the first 30 days after surgery, were retrospectively analyzed. The indexed effective orifice area (iEOA) of the prosthesis was used to classify the patients into three groups, according to PPM, considering body mass index (BMI): severe PPM (iEOA) < 0.65 cm2/m2), mild to moderate PPM (iEOA, 0.65 cm2/m2 - 0.85 cm2/m2) and without PPM (iEOA > 0.85 cm2/m2) for a BMI < 30 kg/m2 and severe PPM (iEOA) < 0.55 cm2/m2), mild to moderate (iEOA, 0.55 cm2/m2- 0.70 cm2/m2) and without PPM (iEOA > 0.7 cm2/m2) for a BMI > 30 kg/m2. Statistical significance was considered when p < 0.05. Results: iEOA was obtained in 176 patients. The frequency of severe and moderate PPM was 33.4% and 36.2%, respectively. Severe PPM patients were younger and had larger BMI, but smaller left ventricular outflow tract diameter (LVOTD). The independent variables used to predict severe PPM were male gender, BMI > 25 kg/m2, age < 60 years, LVOTD < 21 mm, and rheumatic etiology with an area under the ROC curve of 0.82. Conclusion: The frequency of severe PPM is high in a Brazilian population representative of the Public Health System, and it is possible to predict PPM from preoperative variables such as rheumatic valvular disease, gender, BMI, age and LVOTD.


Resumo Fundamento: A desproporção entre o tamanho da prótese aórtica-paciente (DPP) está associada a maior mortalidade. Objetivo: Determinar a frequência e avaliar variáveis ​​pré-operatórias associadas à DPP acentuada no cenário da saúde pública em hospital terciário. Métodos: 316 pacientes submetidos à troca valvar aórtica (TVA), com ecocardiograma realizado nos primeiros 30 dias após cirurgia, foram analisados retrospectivamente. A área de orifício efetivo indexado (AOEi) da prótese foi utilizada para classificar os pacientes em três grupos de acordo com a DPP, considerando o índice de massa corporal (IMC): DPP acentuada (AOEi) < 0,65 cm2/m2, DPP discreta a moderada (AOEi, 0,65 cm2/m2 - 0,85 cm2/m2) e sem DPP (iEOA > 0,85 cm2/m2) para IMC < 30 kg/m2 e DPP acentuada (AOEi) < 0,55 cm2/m2), discreta a moderada (AOEi, 0,55 cm2/m2 - 0,70 cm2/m2) e sem DPP (AOEi > 0,7 cm2/m2) para IMC > 30 kg/m2. Significância estatística foi considerada com p < 0,05. Resultados: A AOEi foi obtida em 176 pacientes. A frequência de DPP acentuada foi de 33,4% e moderada de 36,2%. Pacientes com DPP acentuada foram mais jovens e com maior IMC, mas menor diâmetro da via de saída do ventrículo esquerdo (DVSVE). As variáveis independentes que podem predizer DPP acentuada são: gênero masculino, IMC > 25 kg/m2, idade < 60 anos, DVSVE < 21 mm e etiologia reumática com área sob a curva ROC de 0,82. Conclusão: A frequência de DPP acentuada é alta em uma população brasileira submetida à TVA no Sistema Público de Saúde. Os principais determinantes de DPP acentuada são: valvopatia reumática, gênero masculino, IMC alto, idade < 60 anos e menor DVSVE.

ABSTRACT

RESUMEN INTRODUCCIÓN: En pacientes con estenosis Aórtica (EA) severa sintomática, el implante de válvula aórtica percutánea transcatéter (TAVI) por vía transfemoral constituye el estándar de tratamiento en aquellos de riesgo quirúrgico intermedio o alto. El uso de un abordaje minimalista ha demostrado ser seguro y efectivo, si bien no existen reportes sobre la realidad nacional Métodos: Estudio descriptivo sobre la experiencia con pacientes sometidos al implante de TAVI bajo un protocolo minimalista en Unidad de Cardiología Intervencional y Hemodinamia del Hospital Sótero del Río desde Enero de 2018. Se analizaron las variables clínicas de los pacientes y del procedimiento así como desenlaces clínicos intrahospitalarios y seguimiento alejado. Resultados: Entre Enero 2018 hasta Abril 2019, un total de 10 pacientes fueron sometidos al implante de TAVI por vía transfemoral. El score STS-PROM promedio fue de 7,1. Se logró un implante exitoso en el 100% de los casos con un gradiente medio residual de 8 mmHg y sin leak moderado a severo en ningún paciente. No hubo eventos cerebrovasculares isquémicos perioperatorios ni muerte en este grupo. Se requirió implante de marcapasos definitivo en 3 pacientes y un paciente presentó hematoma femoral perioperatorio que requirió transfusión de glóbulos rojos. La mediana de la estadía hospitalaria fue de 2 días. Conclusiones: El uso de una estrategia minimalista para el implante de TAVI en nuestra realidad nacional es seguro y aplicable. Los resultados perioperatorios y a 30 días fueron comparables a los descritos en experiencias internacionales.


ABSTRACT BACKGROUND: In patients with symptomatic severe aortic stenosis, transcatheter percutaneous aortic valve implant (TAVI) is the standard treatment in those with intermediate or high surgical risk. The use of a minimalist approach has proven to be safe and effective, although there are no reports on the national reality Methods: Descriptive study on the experience with patients undergoing TAVI implantation under a minimalist protocol at the Interventional Cardiology and Hemodynamics Unit of the Hospital Sótero del Río since January 2018. Clinical characteristics of the patients and the procedure were analyzed as well as intrahospital outcomes and at 30-days follow up. Results: Between January 2018 and April 2019, a total of 10 patients underwent TAVI implantation by transfemoral approach in our institution. The average STS-PROM score was 7.1. A successful implant was achieved in 100% of cases with an average residual gradient of 8 mmHg and no moderate to severe leak in any patient. There were no perioperative ischemic cerebrovascular events nor death in this group. A definitive pacemaker implant was required in 3 patients and one patient developed femoral hematoma that required red blood cell transfusion. The median hospital stay was 2 days. Conclusions: The use of a minimalist strategy for TAVI implantation in our national reality is safe and applicable. Immediate results and at 30-days follow up were comparable to those described in international experiences.

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.

ABSTRACT

Abstract A 27-year-old woman with sudden back pain was transported to our hospital. Abdominal ultrasonography revealed pregnancy of 28 weeks' gestation. Computed tomography demonstrated a type A aortic dissection. Because of progressive fetal deterioration, an emergency cesarean section was forced to perform. The next day, simple hysterectomy followed by an aortic procedure was completed. Valve-sparing aortic replacement and total arch replacement were employed as central operations. The mother and baby are well 9 months postoperatively. Although the strategy for acute type A aortic dissection during pregnancy is controversial, collaborations among neonatologists, obstetricians, and cardiovascular surgeons can ensure mother and infant survival.

ABSTRACT

Abstract Quadricuspid aortic valve (QAV) is a rare cardiac malformation. Many cases are incidentally diagnosed in aortic surgeries or autopsies and it usually appears as an isolated anomaly. The most widely classification used is the one by Hurwitz and Roberts[1], which divides 7 alphabetical subtypes based on the cusps size. The aim of this report is to describe three different anatomic presentations of this rare aortic valve anomaly.

ABSTRACT

Abstract In aortic valve disease cases, prosthetic valves have been used for valve replacement, however, these prostheses have inherent problems, and their quality in some countries is lower comparing to new-generation models, causing shorter durability. Aortic valve neocuspidization (AVNeo) has emerged as an option, which can be applied to a wide spectrum of these diseases. Despite the promising results, this procedure is not widely spread among cardiac surgeons yet. We developed a surgical technique combining Bentall and Ozaki procedures to treat patients with concomitant ascending aorta replacement and AVNeo and we describe it in this paper.

ABSTRACT

Abstract We report a case of a 59-year-old female patient with vegetative native mitral valve endocarditis caused by Stenotrophomonas maltophilia (SM). She had hemodialysis-dependent chronic renal failure, but no immunosuppressive disease. Echocardiography showed mobile vegetation on her native mitral valve. Right femoral artery embolectomy and mitral valve replacement were performed simultaneously. She awakened from anesthesia, but she passed away due to septic shock complications. To the best of our knowledge, this was the first case in whom native mitral valve endocarditis caused by SM was observed (despite of absence of any immunosuppressive event) and needed to undergo valve replacement.

ABSTRACT

Abstract Objective: To evaluate the factors impacting on the conversion to sinus rhythm and on the postoperative rhythm findings in the six-month follow-up period of a mitral valve surgery combined with cryoablation Cox-Maze III procedure, in patients with atrial fibrillation. Methods: In this study, we evaluated 80 patients who underwent structural valve disease surgery in combination with cryoablation. Indications for the surgical procedures were determined in the patients according to the presence of rheumatic or non-rheumatic structural disorders in the mitral valve as evaluated by echocardiography. Cox-Maze III procedure and left atrial appendix closure were applied. Results: The results of receiver operating characteristics analysis indicated that the rate of conversion to the sinus rhythm was significantly higher in patients with left atrial diameters ≥ 45.5 mm and with ejection fraction (EF) ≥ 48.5%. However, the statistical differences disappeared in the sixth month. Thromboembolic (TE) events were seen only in three patients in the early period and no more TE events occurred in the six-month follow-up period. Conclusion: The EF and the preoperative left atrial diameter were determined to be the factors impacting on the conversion to sinus rhythm in patients who underwent mitral valve surgery in combination with cryoablation. Mitral valve surgery in combination with ablation for atrial fibrillation does not affect mortality and morbidity in the experienced health centers; however, it remains controversial whether it will provide additional health benefits to the patients compared to those who underwent only mitral valve surgery.

ABSTRACT

Abstract Heyde syndrome manifests as aortic stenosis associated with gastrointestinal bleeding. We describe the case of a 64-year-old man who came to the emergency room due to acute heart failure and intermittent gastrointestinal bleeding. Treatment involves initial correction of anemia and heart failure followed by aortic valve replacement. The prosthesis used depends on the characteristics of each patient and valve replacement allows the resolution of bleeding in most cases. Gastrointestinal bleeding in patients with aortic stenosis is associated with severity of the valve obstruction. A mechanical prosthesis was used with no recurrent bleeding even with the need for lifelong anticoagulation therapy.

ABSTRACT

We report a 65-years old woman with a history of permanent atrial fibrillation with high risk for ischemic and bleeding events. She developed a heart failure with severely impaired left ventricular ejection fraction and severe secondary mitral regurgitation. Given her high surgical risk, using transesophageal echocardiography guidance, a concomitant deployment of two MitraClip devices using a high-posterior septal puncture and a left atrial appendage closure with an Amplatzer Amulet occluder were performed through the same access.

ABSTRACT

Abstract Objective: To analyze and summarize the clinical safety and feasibility of minimally invasive video-assisted mitral valve replacement via a right thoracic minimal incision in patients aged over 65 years. Methods: The clinical data of 45 patients over 65 years old who had mitral valve disease were analyzed retrospectively from January 2014 to January 2017 at Union Hospital, Fujian Medical University. The patients were divided into two groups; 20 patients in group A, who underwent minimally invasive video-assisted mitral valve replacement via a right thoracic minimal incision, and 25 patients in group B, who underwent conventional mitral valve replacement. We collected and analyzed their relevant clinical data. Results: The operation was completed successfully in both groups. Compared with group B, group A was clearly superior for postoperative analgesia time, postoperative hospital length of stay, thoracic drainage liquid, blood transfusion, and length of incision. There were no differences between the two groups in postoperative severe complications and mortality. More patients in group B had pulmonary infections and poor incision healing, while more patients in group A had postoperative pneumothorax and subcutaneous emphysema. Conclusion: In patients aged over 65 years, minimally invasive video-assisted mitral valve replacement with a small incision in the right chest had the same clinical safety and efficacy as the conventional method.

ABSTRACT

SUMMARY BACKGROUND: The use of the 3D printer in complex cardiac surgery planning. OBJECTIVES: To analyze the use and benefits of 3D printing in heart valve surgery through a systematic review of the literature. METHODS: This systematic review was reported following the Preferred Reporting Items for Systematic Review and registered in the Prospero (International Prospective Register of Systematic Reviews) database under the number CRD42017059034. We used the following databases: PubMed, EMBASE, Scopus, Web of Science and Lilacs. We included articles about the keywords "Heart Valves", "Heart Valve Prosthesis Implantation", "Heart Valve Prosthesis", "Printing, Three-Dimensional", and related entry terms. Two reviewers independently conducted data extraction and a third reviewer solved disagreements. All tables used for data extraction are available at a separate website. We used the Cochrane Collaboration tool to assess the risk of bias of the studies included. RESULTS: We identified 301 articles and 13 case reports and case series that met the inclusion criteria. Our studies included 34 patients aged from 3 months to 94 years. CONCLUSIONS: Up to the present time, there are no studies including a considerable number of patients. A 3D-printed model produced based on the patient enables the surgeon to plan the surgical procedure and choose the best material, size, format, and thickness to be used. This planning leads to reduced surgery time, exposure, and consequently, lower risk of infection.


RESUMO INTRODUÇÃO: A impressora 3D é utilizada como coadjuvante no planejamento de cirurgias de cardiopatias complexas. OBJETIVOS: Analisar o uso e os benefícios da impressão 3D em cirurgias de válvula cardíaca por meio de revisão sistemática da literatura. MÉTODOS: Esta revisão sistemática foi conduzida de acordo com os itens do Preferred Reporting for Systematic Reviews e registrada no banco de dados Prospero (Registro Prospectivo Internacional de Revisão Sistemática) sob o número CRD42017059034. Foram utilizados os seguintes bancos de dados: PubMed, Embase, Scopus, Web of Science e Lilacs. Incluídos artigos com os termos de busca "Heart Valves", "Heart Valve Prosthesis Implantation", "Heart Valve Prosthesis", "Printing, Three-Dimensional" e termos relacionados. Dois revisores independentes conduziram a extração dos dados e um terceiro (revisor) solucionou as discordâncias. Todas as tabelas usadas para a extração de dados estão disponibilizadas em site próprio. A ferramenta Cochraine Collaboration foi utilizada para avaliar o risco de viés na inclusão de estudos. RESULTADOS: Identificados 301 artigos e 13 relatos de casos e séries de casos que atenderam aos critérios de inclusão. A amostra envolveu 34 pacientes, com idade de 3 meses a 94 anos. CONCLUSÃO: Até o presente momento, não há estudos que contemplem um número considerável de pacientes. A impressão de um modelo 3D produzida a partir do protótipo do paciente permitirá ao cirurgião planejar a cirurgia, bem como escolher o melhor material, tamanho, formato e espessura da válvula a ser utilizada. Esse planejamento reduz o tempo de cirurgia, a exposição e, consequentemente, a redução do risco de infecção.

ABSTRACT

Abstract Ascending aortic aneurysm is usually associated with aortic valve diseases, especially aortic stenosis. The standard technique involves the substitution of the dilated aortic segment with a Dacron tube and replacement of the aortic valve with a regular prosthesis. The correction of ascending aortic aneurysm with aortic valve replacement using the new sutureless and rapid deployment prosthesis was performed by a minimally invasive approach and for the first time in a Brazilian Center.

ABSTRACT

Abstract We presented a 39-year-old female patient with life-threatening hypoxemia after tricuspid valve replacement because of Ebstein's anomaly. And the severe cyanosis is due to bioprosthetic valve stenosis and atrial septal defect. Anesthetic management of a patient with severe obstructive prosthetic valve dysfunction can be challenging. Similar considerations should be given to patients with Ebstein's anomaly to maintain the pressure equalized between the right and left atrial. Transesophageal echocardiography and cerebral oxygen saturation provided real time information in perioperative care.


Resumo Apresentamos o caso de uma paciente de 39 anos, com hipoxemia em risco de vida após a substituição da valva tricúspide devido à anomalia de Ebstein e cianose grave devido à estenose de valva bioprotética e comunicação interatrial. O manejo anestésico de um paciente com disfunção obstrutiva grave de prótese valvar pode ser um desafio. Os pacientes com anomalia de Ebstein também precisam de atenção especial para manter a pressão equalizada entre o átrio direito e o esquerdo. A ecocardiografia transesofágica e a saturação cerebral de oxigênio forneceram informações em tempo real nos cuidados perioperatórios.

ABSTRACT

Abstract According to the most recent guidelines, the use of intraoperative transesophageal echocardiography in valvular surgeries is well established, as well as its use in the diagnosis, management, and rescue of perioperative complications. The aim of this case report is to illustrate a condition in which its intraoperative use had a positive influence on the outcome.


Resumo O uso da ecocardiografia transesofágica no intraoperatório em cirurgias valvulares é bem estabelecido de acordo com os guidelines mais recentes, assim como o seu uso no diagnóstico, manuseio e resgate de complicações perioperatórias. O objetivo deste relato de caso é ilustrar uma situação em que o seu uso no intraoperatório influenciou de maneira positiva o seu desfecho.
