Como eu faço a avaliação pós-intervenções tricúspides: dicas e truques / My approach to assessment after tricuspid interventions: tips and tricks

A regurgitação tricúspide (RT) importante está associada à alta morbidade e mortalidade. Como o tratamento cirúrgico da RT isolada tem sido associado à alta mortalidade, as intervenções transcateter na valva tricúspide (VT) têm sido utilizadas para o seu tratamento, com risco relativamente mais baixo. Há um atraso na intervenção da RT e provavelmente está relacionado a uma compreensão limitada da anatomia da VT e do ventrículo direito, além da subestimação da gravidade da RT. Nesse cenário, faz-se necessário o conhecimento anatômico abrangente da VT, a fisiopatologia envolvida no mecanismo de regurgitação, assim como a sua graduação mais precisa. A VT tem peculiaridades anatômica, histológica e espacial que fazem a sua avalição ser mais complexa, quando comparado à valva mitral, sendo necessário o conhecimento e treinamento nas diversas técnicas ecocardiográficas que serão utilizadas frequentemente em combinação para uma avaliação precisa. Esta revisão descreverá a anatomia da VT, o papel do ecocardiograma no diagnóstico, graduação e fisiopatologia envolvida na RT, as principais opções atuais de tratamento transcateter da RT e a avaliação do resultado após intervenção transcateter por meio de múltiplas modalidades ecocardiográficas.(AU)

Severe tricuspid regurgitation (TR) is associated with high morbidity and mortality. Given that surgical treatment of TR alone has been associated with high mortality, transcatheter interventions in the tricuspid valve (TV) have been used for its treatment, with relatively lower risk. There is a delay in intervention for TR, and this is probably related to a limited understanding of the anatomy of the TV and the right ventricle, in addition to an underestimation of the severity of TR. In this scenario, it is necessary to have comprehensive anatomical knowledge of the TV, the pathophysiology involved in the mechanism of regurgitation, and more accurate grading. The TV has anatomical, histological, and spatial peculiarities that make its assessment more complex when compared to the mitral valve, requiring knowledge and training in the various echocardiographic techniques that will often be used in combination for accurate assessment. This review will describe the anatomy of the TV, the role of echocardiography in the diagnosis, grading, and pathophysiology involved in TR; the main transcatheter treatment options currently available for TR; and the assessment of outcomes after transcatheter intervention by means of multiple echocardiographic modalities.(AU)

Excursão sistólica do anel tricúspide e do anel mitral: correlação com função diastólica ventricular esquerda / Tricuspid annular plane systolic excursion and mitral annular systolic excursion: correlation with left ventricular diastolic function

Introdução: A excursão sistólica do anel tricúspide e a do anel mitral são parâmetros utilizados para se avaliar a função contrátil do ventrículo direito e do ventrículo esquerdo, respectivamente. Pouco se conhece sobre sua relação com a função diastólica ventricular esquerda. Objetivo: Avaliar se os valores de excursão sistólica do anel tricúspide e do anel mitral se correlacionam com parâmetros utilizados na avaliação da função diastólica ventricular esquerda. Métodos: Estudo observacional transversal. Foram selecionados 219 indivíduos, sendo 116 mulheres, com função sistólica preservada de ambos os ventrículos. As análises foram feitas separadamente para os sexos masculino e feminino, por meio dos coeficientes de correlação de Pearson e de Sperman. Foram obtidos: excursão sistólica do anel tricúspide, excursão sistólica do anel mitral, volumes atriais e medidas relacionadas à avaliação da função diastólica do ventrículo esquerdo ao ecocardiograma transtorácico. Resultados: No sexo feminino, a excursão sistólica do anel mitral se correlacionou positivamente com o e' lateral (coeficiente de correlação de Sperman de 0,22; p=0,016) e a excursão sistólica do anel tricúspide se correlacionou positivamente com a relação E/A (coeficiente de correlação de Sperman de 0,23, p=0,037), com o e' lateral (coeficiente de correlação de Sperman de 0,28; p=0,012), com o e' septal (coeficiente de correlação de Sperman de 0,28; p=0,012) e negativamente com a relação E/e' (coeficiente de correlação de Pearson de -0,27; p=0,018) e onda A (coeficiente de correlação de Pearson de -0,29; p= 0,009). No sexo masculino, apenas a excursão sistólica do anel mitral se correlacionou positivamente com a onda E (coeficiente de correlação de Pearson de 0,21; p=0,037), e' lateral (coeficiente de correlação de Sperman de 0,34; p <0,001) e e' septal (coeficiente de correlação de Sperman de 0,26; p=0,008). Não houve correlação entre excursão sistólica do anel mitral e do anel tricúspide e volumes atriais. A presença de hipertensão arterial sistêmica e diabetes melito influenciou nos valores de excursão sistólica do anel tricúspide e do anel mitral correlacionados a ondas E e A, relação E/A, ondas e' septal e lateral e relação E/e'. Conclusão: No presente estudo, os valores da excursão sistólica do anel mitral e do anel tricúspide apresentaram correlação significativa com algumas variáveis da função diastólica ventricular esquerda com maior evidência no sexo feminino.(AU)

Introduction: Tricuspid annular plane systolic excursion and mitral annular systolic excursion are parameters used to assess the systolic function of the right ventricle and left ventricle, respectively. Little is known about its relationship with left ventricular diastolic function. Objective: To assess whether the values of mitral annular systolic excursion and tricuspid annular plane systolic excursion correlate with parameters used in the evaluation of left ventricular diastolic function. Method: Observational cross-sectional study. Two hundred nine individuals were selected, 116 women, with both ventricles normal systolic function. The analyzes were performed for men and women, through Pearson correlation coefficient and Sperman correlation coefficient. Tricuspid annular plane systolic excursion, mitral annular systolic excursion, atrial volumes and left ventricular diastolic function parameters on transthoracic echocardiogram were obtained. Results: In women, mitral annular systolic excursion was positively correlated with lateral e '(Sperman correlation coefficient of 0.22; p=0.016) and tricuspid annular plane systolic excursion was positively correlated with E / A ratio (Sperman correlation coefficient of 0.23; p=0.037), lateral e' (Sperman correlation coefficient of 0.28; p=0.012), and septal e' (Sperman correlation coefficient of 0.28; p=0.012), and negatively with the E/e' ratio (Pearson correlation coefficient of -0.27; p=0.018), and A wave (Pearson correlation coefficient of -0.29; p=0.009). In men, only mitral annular systolic excursion correlated positively with E wave (Pearson correlation coefficient of 0.21; p=0.037), lateral e' (Sperman correlation coefficient of 0.34; p <0.001) and the septal e' (Sperman correlation coefficient of 0.26; p=0.008). There was no correlation between mitral annular systolic excursion E and tricuspid annular plane systolic excursion and atrial volumes. Hypertension and diabetes mellitus influenced tricuspid annular plane systolic excursion and mitral annular systolic excursion values correlated to E and A waves, E/A ratio, septal and lateral e' waves, and E/e' ratio. Conclusion: In the present study, mitral annular systolic excursion and tricuspid annular plane systolic excursion values showed a significant correlation with some parameters of left ventricular diastolic function, with stronger evidence on female sex.(AU)

Mitral Valve Fenestration as a Rare Cause of Congenital Mitral Insufficiency Successfully Repaired

Abstract A rare case of congenital mitral insufficiency characterized by a fenestration in the anterior leaflet of mitral valve is reported. At operation, the mitral valve was successfully repaired by closure of unusual valvular tissue orifice with bovine pericardium and suture of the free edge between A1 and A2 without a ring annuloplasty.

Comparison between different tricuspid valve procedures through postoperative inflammation and myocardial enzymes

Abstract Introduction: The thoracoscopic procedure for tricuspid valve (TV) diseases is a minimally invasive method of treatment. This study focuses on comparing the changes in postoperative inflammatory reaction and myocardial injury markers after thoracoscopic and sternotomy/thoracotomy TV procedures. Methods: We retrospectively analyzed 88 patients (53 males, aged 50.9±16.2 years) with TV diseases (single-valve disease) (72 cases of TV plasty) between January 2018 and April 2019. A total of 56 patients underwent thoracoscopic procedure (50 cases of TV plasty). The leukocyte and C-reactive protein (CRP) levels were monitored as indicators of systemic inflammatory reaction. The lactate dehydrogenase, creatine kinase, creatine kinase myocardial band, aspartate aminotransferase, and troponin-T levels were recorded as markers of myocardial injury. Results: The CRP and white blood cells levels of patients in the sternotomy approach group were continuously higher than those in patients in the thoracoscopic approach group. And the levels of myocardial enzymes in patients in the thoracoscopic approach group were significantly lower than those in patients in the sternotomy approach group. Conclusion: Compared with sternotomy/thoracotomy procedures on TV, the thoracoscopic procedure can reduce postoperative myocardial injury significantly and systemic inflammatory reaction to a certain extent. It is technically feasible, safe, effective, and worthy of widespread adoption in clinical practice.

Late tricuspid regurgitation after percutaneous transcatheter closure of ventricular septal defect: an educational presentation

Abstract Transcatheter closure of ventricular septal defects (VSD) is not out of complications. Late complications are rare, but important, and sometimes require surgical correction. Herein, we report a case of tricuspid regurgitation as a complication of transcatheter VSD closure. The patient underwent successful surgery. Postoperative course was satisfactory. Echocardiographic examination revealed well-functioning tricuspid valve. We present this case since valve regurgitation after transcatheter procedure requiring surgery is an uncommon but significant complication due to heart failure risk. Even in the absence of any clinical finding, post-procedural close follow-up is important for early diagnosis of the problem to prevent the aforementioned risk.

Tricuspid valve repair with autologous pericardium in a patient with infective endocarditis

Abstract Infective endocarditis is a rather uncommon disease, but it has significant mortality rates in the pediatric population (5% to 10%). We report a case of an infant patient with multiple vegetation in the tricuspid valve secondary to infective endocarditis caused by Corynebacterium diphtheriae. A tricuspid valvuloplasty was performed with a fenestrated autologous pericardium patch, providing satisfactory outcomes. This technique is simple, innovative, effective, and it could be applied in similar cases.

Safety and efficacy of transcatheter tricuspid valve replacement with LuX-Valve in patients with severe tricuspid regurgitation / 中华心血管病杂志

Objectives: To evaluate the safety and efficacy of LuX-Valve on the treatment of severe tricuspid regurgitation (TR). Methods: This is a prospective observational study. From September 2018 to March 2019, 12 patients with severe TR, who were not suitable for surgery, received LuX-Valve implantation in Changhai Hospital. LuX-Valve was implanted under general anesthesia and the guidance of transesophageal echocardiography and X-ray fluoroscopy. Access to the tricuspid valve was achieved via a minimally invasive thoracotomy and transatrial approach. Main endpoints were surgery success and device success. Surgery success was defined as successful implanting the device and withdrawing the delivery system, positioning the valve correctly and stably without severe or life-threatening adverse events. Device success was defined as satisfied valve function (TR severity reduction ≥ 2 grades, tricuspid gradient ≤ 6 mmHg (1 mmHg=0.133 kPa)), absence of malposition, valve failure and reintervention, major adverse events including device related mortality, embolization, conduction system disturbances and new onset shunt across ventricular septum at day 30 post implantation. Results: A total of 12 patients with severe to torrential TR were included in this study. The age was (68.5±6.9) years and 7 were female. All patients had typical right heart failure symptoms. Procedural success was achieved in all cases, there was no intraprocedural mortality or transfer to open surgery. TR significantly improved after LuX-Valve implantation (none/trivial in 8 patients, mild in 3 patients and moderate in 1 patient). The average device time was (9.2±4.2) minutes. Intensive care unit duration was 3.0 (2.0, 4.8) days. One patient died at postoperative day 18 due to non-surgery and device reasons. Transthoracic echocardiography at 30 days after operation showed that TR was significantly reduced (none/trivial in 8 patients, mild in 2 patients and moderate in 1 patient) and device success was achieved in 11 cases. All survived patients experienced a significant improvement in life quality with significantly improvement in New York Heart Association (NYHA) classification (Ⅰ and Ⅱ: 6/11 post operation vs. 0/11 before operation, P=0.012) and there were no device related complications in this patient cohort. Conclusions: LuX-Valve implantation is feasible, safe and effective for the treatment of patients with severe TR.

Mortality rates of surgical techniques for correcting atrioventricular disjunction

Abstract We compared the mortality rates of two surgical techniques for correction of atrioventricular disjunction in 10 out of 720 patients who underwent mitral valve replacement from 2005 to 2012. In group I, the mitral annulus was fixed with bovine pericardial strips; in group II, a 'patch' of bovine pericardium was sutured and extended from the base of the lateral and medial papillary muscles, covered the posterior wall of the left ventricle, went through the posterior mitral annulus, and ended in the posterior wall of the left atrium adjacent to the mitral ring. The group II technique showed a lower mortality.

Mid-term outcome after tricuspid valve replacement

Abstract Objective: To evaluate the mid-term survival rate after tricuspid valve replacement (TVR). Methods: We retrospectively studied 110 consecutive patients who underwent TVR from January 2007 to November 2017. A survival analysis was performed with the Kaplan-Meier method and the log-rank test. Results: The median survival was 65.81 months. Mean age was 50 (range 39 to 59) years. Forty-eight patients (43.6%) were male, and 62 patients (56.4%) were female. Most of the patients (78.5%) were categorized into the New York Heart Association (NYHA) functional classes III/IV. Seventy-two patients (65.5%) had isolated TVR. Six-three patients (57.3%) had previously undergone heart surgery. The Kaplan-Meier survival rates at one year, three years, and five years were 59.0%±5%, 52.0%±6%, and 48.0%±6%, respectively. A Cox regression analysis demonstrated that the risk factors for mid-term mortality were advanced NYHA class (hazard ratio [HR] 2.430, 95% confidence interval [CI] 1.099-5.375, P=0.028), need for continuous renal replacement therapy (CRRT) treatment (HR 3.121, 95% CI 1.610-6.050, P=0.001), and need for intra-aortic balloon pump (IABP) treatment (HR 3.356, 95% CI 1.072-10.504, P=0.038). Conclusion: In TVR, impaired cardiac function before the operation and a need for CRRT or IABP treatment after the operation is independently associated with increased mid-term mortality.

Válvula tricúspide displásica (Ebstein-like) / Tricuspid valve dysplasia (Ebstein-like)

Resumen La anomalía de Ebstein es una malformación caracterizada por el desplazamiento apical de las inserciones de las valvas septal y posterior de la válvula tricúspide, así como del anillo funcional tricúspide y por la atrialización del ventrículo derecho. Se han encontrado casos durante cirugías que no han cumplido con estos criterios, y que, por tanto, se han clasificado como "anomalías Ebstein-like". Algunos de ellos han sido descritos anatómicamente como válvulas displásicas. Se presenta el caso de una mujer de 20 años que presentó disnea clase III de la Asociación del Corazón de Nueva York y dolor punzante en el pecho, que se clasificó como una posible anomalía de Ebstein por ecocardiografía; sin embargo, los hallazgos intraoperatorios fueron compatibles con una válvula tricúspide displásica con dilatación del anillo funcional. Este caso destaca la importancia del uso adecuado de la ecocardiografía, así como la necesidad de estudios prospectivos sobre los casos de Ebstein-like.

Abstract The Ebstein anomaly is a malformation characterised by the apical displacement of the insertions of the septal valve and the posterior tricuspid valve, displaced tricuspid functional ring, and atrialisation of the right ventricle. Cases have been found during surgery that have complied with these criteria, and have therefore been classified as "Ebstein-like anomalies". Some of them have been described anatomically as valve dysplasia. The case is presented of a 20 year-old female that presented with dyspnoea Class III of the New York Heart Association, and a stabbing pain in the chest. This was classified as a possible Ebstein anomaly by cardiac ultrasound. However the findings during the surgery were compatible with tricuspid valve dysplasia with dilation of the functional ring. This case highlights the importance of the appropriate use of cardiac ultrasound, as well as the need to carry out prospective studies on Ebstein-like cases.

Reemplazo valvular tricuspídeo: prótesis mecánica versus prótesis biológica: trabajo observacional-descriptivo / Tricuspide valve replacement: comparison of biological versus mechanical valve: a descriptive observational study

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.

Parameters assessed were the following: proximal, basal, medium and longitudinal, right ventricle diameter; right atrium area and right atrium volume; right ventricle wall thickness; tricuspid annular plane systolic excursion; and tricuspid annulus tissue Doppler and S' wave. Results: Female sex presented lower diameters (Student's t-test) of proximal right ventricle diameter (20.6 mm ± 2.4 vs. 22.7 mm ± 2.2; p = 0.001), basal right ventricle diameter (34,4 mm ± 3,5 vs. 38,2 mm ± 4,8; p <0.001), medium right ventricle diameter (27 mm ± 3.3 vs. 32.4 mm ± 4.9; p <0.001), right atrium area (13.7 cm² ± 2.7 vs. 16.6 cm² ± 3.9; p = 0.002) and right atrium volume (37 mL ± 10.6 vs.

Endocarditis infecciosa en válvula tricúspide: Presentación clínica y evolución en paciente sin factores de riesgo clásicos. Endocarditis infecciosa tricuspídea: a propósito de un caso / Infective endocarditis in the tricuspid valve: Clinical presentation and evolution in patient without classic risk factors. Tricuspid infectious endocarditis: a case report

Infective endocarditis (IE) correspond to a serious condition of the endocardium, with clinical and classic risk factors. Heart failure is described as the main complication and cause of mortality. A 58-year-old diabetic female patient, with fever, weight loss and history of 10 months of fatigue, is presented below. She is hospitalized in Hospital Regional de Talca, in Medicine Service, where she is diagnosed of right IE by blood cultures (Streptococcus Sanguis) and transthoracic echocardiogram, that showed vegetations in the tricuspid valve and severe insufficiency. Without clinical improvement despite antibiotic treatment, echocardiography is repeated, showing persistence of vegetations and insufficiency, so that surgical resolution is decided, taking place in Hospital Gustavo Grant Benavente Concepción, with clinical recovery after surgery. It highlights a classic and larval presentation of the disease, but without classic risk factors for right IE, also associated with glomerulonephritis. The antibiotic eliminated bacteremia, but the valve damage was already established.

Nesta revisão, abordaremos as principais técnicas ecocardiográficas para o diagnóstico e a avaliação hemodinâmica da hipertensão pulmonar na população pediátrica. O diagnóstico precoce e o adequado estadiamento no acompanhamento das intervenções clínicas são fundamentais para escolha assertiva da abordagem terapêutica e, consequentemente, melhora do desfecho clínico

Early and long-term outcomes of surgical treatment of ebstein's anomaly

Abstract Objective: This study aimed to evaluate Ebstein's anomaly surgical correction and its early and long-term outcomes. Methods: A retrospective analysis of 62 consecutive patients who underwent surgical repair of Ebstein's anomaly in our institution from January 2000 to July 2016. The following long-term outcomes were evaluated: survival, reoperations, tricuspid regurgitation, and postoperative right ventricular dysfunction. Results: Valve repair was performed in 46 (74.2%) patients - 12 of them using the Da Silva cone reconstruction; tricuspid valve replacement was performed in 11 (17.7%) patients; univentricular palliation in one (1.6%) patient; and the one and a half ventricle repair in four (6.5%) patients. The patients' mean age at the time of surgery was 20.5±14.9 years, and 46.8% of them were male. The mean follow-up time was 8.8±6 years. The 30-day mortality rate was 8.06% and the one and 10-year survival rates were 91.9% both. Eleven (17.7%) of the 62 patients required late reoperation due to tricuspid regurgitation, in an average time of 7.1±4.9 years after the first procedure. Conclusion: In our experience, the long-term results of the surgical treatment of Ebstein's anomaly demonstrate an acceptable survival rate and a low incidence of reinterventions.
