ABSTRACT

Abstract Introduction: Reoperations in cardiac surgery represent a clinical challenge, particularly because of the higher rate of perioperative morbidity and mortality. Mitral valve reoperation owing to bioprosthesis dysfunction, transcatheter treatment with a prosthesis implantation over the prosthesis has emerged as an alternative, especially for patients with a previous approach. In this study, we analyzed the hydrodynamic behavior of transcatheter prosthesis implantation in conventional mitral bioprostheses through hydrodynamic tests and produced a recommendation for the size of transcatheter valve most adequate for valve-in-valve procedure. Methods: Mitral bioprostheses were attached to a flow duplicator and different combinations of transcatheter prostheses were implanted inside. The equipment simulates the hydrodynamic behavior of the valves submitted in vitro and determines transvalvular pressures and flow parameters. Results: All tests could be performed. Better hydrodynamic performance occurred for transcatheter prostheses 1 mm smaller than bioprostheses, except for the 27-mm bioprostheses. Effective valve areas (cm²) and transvalvular gradients (mmHg) were, respectively: Bioprosthesis × Inovare: 27 × 28 mm: 1.65 and 5.95/29 × 28 mm and 31 × 30 mm: 2.15 and 3.6. Conclusion: The mitral valve-in-valve implantation proved to be feasible in vitro. The use of 27-mm bioprostheses should be judicious, with preference for a 26-mm transcatheter valve. In the 29 and 31-mm bioprostheses, the implantation was very satisfactory, with good effective valve areas and transvalvular gradients, with preference for smaller transcatheter valves.

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

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 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.

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: The Instantaneous Wave-Free Ratio (iFR) is an invasive functional evaluation method that does not require vasoactive drugs to induce maximum hyperemia Objective: To evaluate the contribution of the iFR to the therapeutic decision-making of coronary lesions in the absence of non-invasive diagnostic methods for ischemia, or in case of discordance between these methods and coronary angiography. Method: We studied patients older than 18 years, of both sexes, consecutively referred for percutaneous treatment between May 2014 and March 2018. Coronary stenotic lesions were classified by visual estimation of the stenosis diameter into moderate (41-70% stenosis) or severe (71%-90%). An iFR ≤ 0.89 was considered positive for ischemia. Logistic regression was performed using the elastic net, with placement of stents as outcome variable, and age, sex, arterial hypertension, diabetes, dyslipidemia, smoking, family history, obesity and acute myocardial infarction (AMI) as independent variables. Classification trees, ROC curves, and Box Plot graphs were constructed using the R software. A p-value < 0.05 was considered statistically significant. Results: Fifty-two patients with 96 stenotic lesions (56 moderate, 40 severe) were evaluated. The iFR cut-off point of 0.87 showed a sensitivity of 0.57 and 1-specificity of 0.88, demonstrating high accuracy in reclassifying the lesions. Diabetes mellitus, dyslipidemia, and presence of moderate lesions with an iFR < 0.87 were predictors of stent implantation. Stents were used in 32% of lesions in patients with stable coronary artery disease and AMI with or without ST elevation (non-culprit lesions). Conclusion: The iFR has an additional value to the therapeutic decision making in moderate and severe coronary stenotic lesions, by contributing to the reclassification of lesions and decreasing the need for stenting.


Resumo Fundamento: Instantaneous Wave-Free Ratio (iFR) é um método de avaliação funcional invasiva sem necessidade de droga vasoativa para indução de hiperemia máxima. Objetivo: Analisar a contribuição do iFR na terapêutica das lesões coronarianas com ausência ou discrepância entre os métodos diagnósticos não invasivos para isquemia e a angiografia coronária. Método: Foram estudados pacientes consecutivos com 18 anos ou mais, ambos os sexos, no período de maio de 2014 a março de 2018, com lesões coronarianas classificadas, por medição da porcentagem de diâmetro da estenose através de estimativa visual, em estenoses moderadas (41-70%) ou graves (71%-90%). O iFR ≤ 0,89 foi considerado positivo para isquemia. Empregou-se regressão logística com elastic net, tendo como variável desfecho o emprego de stent, e variáveis independentes: idade, sexo, hipertensão arterial, diabetes, dislipidemia, tabagismo, história familiar, obesidade e infarto agudo do miocárdio (IAM) prévio. Foram construídas Árvores de Classificação, Curva Roc, e gráficos Box Plot com o software R. O valor de p < 0,05 foi considerado significativo. Resultados: Foram avaliados 52 pacientes com 96 lesões obstrutivas (56 moderadas, 40 graves). O ponto de corte do iFR de 0,87 apresentou sensibilidade de 0,57 e 1-especificidade de 0,88, demonstrando boa acurácia para a reclassificação das lesões. Diabetes mellitus, dislipidemia, e presença de lesão moderada, com iFR < 0,87 foram preditores do implante de stents. Foram empregados stents em 32% das lesões de portadores de doença arterial coronariana estável e IAM com e sem supra de ST (lesões não culpadas). Conclusão: O iFR contribui para a reclassificação das lesões e diminuição do emprego de stents, auxiliando na abordagem das lesões moderadas e severas.

ABSTRACT

Abstract Background: Coronary angiography with two catheters is the traditional strategy for diagnostic coronary procedures. TIG I catheter permits to cannulate both coronary arteries, avoiding exchanging catheters during coronary angiography by transradial access. Objective: The aim of this study is to evaluate the impact of one-catheter strategy, by avoiding catheter exchange, on coronary catheterization performance and economic costs. Methods: Transradial coronary diagnostic procedures conducted from January 2013 to June 2017 were collected. One-catheter strategy (TIG I catheter) and two-catheter strategy (left and right Judkins catheters) were compared. The volume of iodinated contrast administered was the primary endpoint. Secondary endpoints included radial spasm, procedural duration (fluoroscopy time) and exposure to ionizing radiation (dose-area product and air kerma). Direct economic costs were also evaluated. For statistical analyses, two-tailed p-values < 0.05 were considered statistically significant. Results: From a total of 1,953 procedures in 1,829 patients, 252 procedures were assigned to one-catheter strategy and 1,701 procedures to two-catheter strategy. There were no differences in baseline characteristics between the groups. One-catheter strategy required less iodinated contrast [primary endpoint; (60-105)-mL vs. 92 (64-120)-mL; p < 0.001] than the two-catheter strategy. Also, the one-catheter group presented less radial spasm (5.2% vs. 9.3%, p = 0.022) and shorter fluoroscopy time [3.9 (2.2-8.0)-min vs. 4.8 (2.9-8.3)-min, p = 0.001] and saved costs [149 (140-160)-€/procedure vs. 171 (160-183)-€/procedure; p < 0.001]. No differences in dose-area product and air kerma were detected between the groups. Conclusions: One-catheter strategy, with TIG I catheter, improves coronary catheterization performance and reduces economic costs compared to traditional two-catheter strategy in patients referred for coronary angiography.


Resumo Fundamento: A cineangiocoronariografia com dois cateteres é a estratégia tradicional para procedimentos coronarianos de diagnóstico. O cateter TIG I permite canular ambas as artérias coronárias, evitando a troca de cateteres durante a cineangiocoronariografia por acesso transradial. Objetivo: O objetivo deste estudo é avaliar o impacto da estratégia de um cateter, evitando a troca de cateter, no desempenho da coronariografia por cateterismo e nos seus custos econômicos. Métodos: Foram coletados os procedimentos diagnósticos coronarianos transradiais realizados entre janeiro de 2013 e junho de 2017. A estratégia de um cateter (cateter TIG I) e a estratégia de dois cateteres (cateteres coronários direito e esquerdo de Judkins) foram comparadas. O volume de contraste iodado administrado foi o endpoint primário. Os endpoints secundários eram espasmo radial, duração do procedimento (tempo de fluoroscopia) e exposição a radiações ionizantes (produto dose-área e kerma no ar). Os custos econômicos diretos também foram avaliados. Para as análises estatísticas, valores de p < 0,05 bicaudais foram considerados estatisticamente significativos. Resultados: De um total de 1.953 procedimentos em 1.829 pacientes, 252 procedimentos foram atribuídos à estratégia de um cateter e 1.701 procedimentos à estratégia de dois cateteres. Não houve diferenças nas características basais entre os grupos. A estratégia de um cateter exigiu menos contraste iodado [endpoint primário; (60-105) -mL vs. 92 (64-120) -mL; p < 0,001] em comparação com a estratégia de dois cateteres. Além disso, o grupo da estratégia de um cateter apresentou menos espasmo radial (5,2% vs. 9,3%, p = 0,022) e menor tempo de fluoroscopia [3,9 (2,2-8,0) -min vs. 4,8 (2,9-8,3) -min, p = 0,001] e economia de custos [149 (140-160)-€/procedimento vs. 171 (160-183) -€/procedimento; p < 0,001]. Não foram detectadas diferenças no produto dose-área e kerma no ar entre os grupos. Conclusões: A estratégia de um cateter, com cateter TIG I, melhora o desempenho da coronariografia por cateterismo e reduz os custos econômicos em comparação com a estratégia tradicional de dois cateteres em pacientes encaminhados para cineangiocoronariografia.

ABSTRACT

Abstract Background: Left atrial appendage (LAA) occlusion is an alternative therapy for atrial fibrillation patients who have high embolic risk and contraindications to anticoagulant therapy. Objective: To evaluate the feasibility, safety, and mid-term outcomes of percutaneous LAA occlusion, including device-related thrombosis. Methods: Sixty consecutive patients who had undergone percutaneous LAA occlusion with AMPLATZER™ Amulet™ device from September 2015 to March 2018 were enrolled. Patients were followed for 21 ± 15 months (median - 20 months, interquartile range - 9 to 27 months). The postprocedural assessment was done at the 1(st), 6(th), and 12(th) month. Patients were clinically evaluated, and transesophageal echocardiography was performed at each visit. We evaluated the condition of normality of variables using the Kolmogorov-Smirnov test. P-values < 0.05 were statistically significant. Results: The most common indication for the procedure was major bleeding with anticoagulants (n: 53, 88.3%). The procedure was completed successfully in 59 (98.3%) patients. Periprocedural mortality was observed in one patient. Postprocedural antiplatelet treatment was planned as dual or single antiplatelet therapy or low-dose anticoagulant therapy in 52 (88.1%), 2 (3.4%), and 5 (8.5%) patients, respectively. We found no clinically significant cerebrovascular events, device-related thrombus, or embolization in any patient during the follow-up. Two (3.4 %) patients presented significant peri-device leak (>3 mm) at the 1st month evaluation, which disappeared at the 12th month follow-up. Conclusion: We concluded that LAA occlusion using the Amulet™ LAA occluder can be performed with high procedural success and acceptable outcomes.


Resumo Fundamento: A oclusão do apêndice atrial esquerdo (AAE) é uma terapia alternativa para pacientes com fibrilação atrial que tenham alto risco embólico e contraindicações à terapia anticoagulante. Objetivo: Avaliar a viabilidade, segurança e resultados de médio prazo da oclusão percutânea do AAE, incluindo a trombose relacionada à prótese. Métodos: Sessenta pacientes consecutivos que foram submetidos à oclusão percutânea do AAE com a prótese AMPLATZER™ Amulet™ de setembro de 2015 a março de 2018 foram incluídos no estudo. Os pacientes foram acompanhados por 21 ± 15 meses (mediana - 20 meses, intervalo interquartílico - 9 a 27 meses). A avaliação pós-procedimento foi feita no 1º, 6º e 12º mês. Os pacientes foram examinados clinicamente e um ecocardiograma transesofágico foi realizado a cada visita. A condição de normalidade das variáveis foi avaliada por meio do teste de Kolmogorov-Smirnov. Os valores de p < 0,05 foram considerados estatisticamente significativos. Resultados: A indicação mais comum para o procedimento foi sangramento significativo com anticoagulantes (n: 53, 88,3%). O procedimento foi concluído com sucesso em 59 (98,3%) pacientes. Mortalidade peri-procedimento ocorreu em um paciente. A tratamento antiplaquetário pós-procedimento foi planejado como terapia antiplaquetária única ou dupla ou terapia anticoagulante de dose baixa em 52 (88,1%), 2 (3,4%) e 5 (8,5%) pacientes, respectivamente. Não foram encontrados eventos cerebrovasculares clinicamente significativos, trombo relacionado à prótese ou embolização nos pacientes durante o seguimento. Dois (3,4%) pacientes apresentaram vazamento peri-prótese significativo (>3 mm) na avaliação do 1º mês, que desapareceu no 12º mês de seguimento. Conclusão: Concluiu-se que a oclusão do AAE com o oclusor de AAE Amulet™ pode ser realizada com grande sucesso e resultados aceitáveis.

ABSTRACT

El cateterismo cardíaco en niños ha mostrado un avance significativo en las últimas décadas, transformándose de un procedimiento casi exclusivamente diagnóstico en sus inicios a un método predominantemente terapéutico en la actualidad. Para ello han contribuido la aparición de múltiples tecnologías de imágenes, así como el creciente desarrollo de materiales de muy bajo perfil y gran versatilidad que permiten el empleo de dispositivos cada vez más específicos para tratar adecuadamente un sinnúmero de enfermedades cardíacas con gran eficacia y seguridad. Esta tendencia continúa creciendo día a día, con la ayuda de nuevas modalidades de tratamiento híbrido donde cardiólogos intervencionistas y cirujanos cardiovasculares interactúan para ayudarse mutuamente, de manera tal de resolver los problemas existentes o aquellos que se van generando con el correr de los años y que afectan la vida de nuestros pacientes. Existen aún como es lógico controversias en algunos casos especiales, que se irán resolviendo paulatinamente en base a la evidencia reunida con las diferentes terapéuticas médicas utilizadas para mejorar el presente y futuro de los niños con cardiopatías (AU)


Cardiac catheterization in children has shown significant progress in recent decades, transforming from an initially almost exclusively diagnostic procedure to a predominantly therapeutic method today. The emergence of multiple imaging technologies has contributed to this progress, as has the growing development of very low-profile and highly versatile materials that allow the use of increasingly specific devices to adequately treat different types of heart disease with great efficacy and safety. This trend continues to grow day by day, with the help of new hybrid treatment modalities where interventional cardiologists and cardiovascular surgeons interact with mutual support, in order to solve existing problems or those that are generated over the years affecting the lives of our patients. Obviously, there are still controversies in specific cases, which will gradually be resolved based on the evidence that becomes available with the use of different medical therapies used to improve the present and future of children with heart disease.(AU)

ABSTRACT

Abstract Objective: In this retrospective study, we aimed to observe the efficacy of pericardial effusion (PE) treatments by a survey conducted at the Department of Cardiovascular Surgery, Faculty of Medicine, Atatürk University. Methods: In order to get comparable results, the patients with PE were divided into three groups - group A, 480 patients who underwent subxiphoid pericardiostomy; group B, 28 patients who underwent computerized tomography (CT)-guided percutaneous catheter drainage; and group C, 45 patients who underwent echocardiography (ECHO)-guided percutaneous catheter drainage. Results: In the three groups of patients, the most important symptom and physical sign were dyspnea and tachycardia, respectively. The most common causes of PE were uremic pericarditis in patients who underwent tube pericardiostomy, postoperative PE in patients who underwent CT-guided percutaneous catheter drainage, and cancer-related PE in patients who underwent ECHO-guided percutaneous catheter drainage. In all the patients, relief of symptoms was achieved after surgical intervention. There was no treatment-related mortality in any group of patients. In patients with tuberculous pericarditis, the rates of recurrent PE and/or constrictive pericarditis progress were 2,9% and 2,2% after tube pericardiostomy and ECHO-guided percutaneous catheter drainage, respectively. Conclusion: Currently, there are many methods to treat PE. The correct treatment method for each patient should be selected according to a very careful analysis of the patient's clinical condition as well as the prospective benefit of surgical intervention.
