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)

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.

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.

Early Outcomes of Modified De Vega Annuloplasty for Functional Tricuspid Regurgitation at a Brazilian Hospital

Abstract Background: Right valve diseases are not benign, the tricuspid regurgitation has a significant impact on morbidity and mortality of patients. Objectives: This study aimed to report the short-term results of tricuspid annuloplasty using the De Vega technique modified by Manuel Antunes. Methods: A descriptive-analytical study was performed to evaluate the results of the tricuspid valvuloplasty performed at the Instituto de Medicina Integral Professor Fernando Figueira between 2012 and 2017. Data were collected by reviewing charts and databases of the Department of Cardiology and Cardiovascular Surgery of the institution. Those with rheumatic diseases or infective endocarditis with tricuspid valve involvement, or reoperation of the tricuspid valve were excluded. Student's t-test and McNemar's were used for statistical analysis. A p-value < 0.05 was considered statistically significant. Results: A total of 87 patients were studied, most of them were women (56.3%). The most associated heart valve diseases were mitral regurgitation (27.6%) and aortic regurgitation (20.7%). There was a significant decrease in the degree of tricuspid regurgitation in the postoperative period, with 83.3% of patients with none or mild regurgitation and only 1.1% with severe regurgitation (p = 0.0077). Conclusions: In the current study, tricuspid valve annuloplasty using the modified De Vega technique was shown to be effective in the short term. Further studies are needed to evaluate the long-term results.

Transcatheter closure of paravalvular leaks: short- and medium-term outcomes / Cierre transcatéter de fugas paravalvulares: resultados a corto y mediano plazo

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.

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.

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.

La mortalidad post operatoria global fue 16%, debido a falla multisistémica en 6%, insuficiencia cardíaca en 5% y hemorragia cerebral en 4.3%. El seguimiento promedio fue 78.8 (DS 7.2) meses. La supervivencia actuarial fue 74% a los 60 y 68% a los 96 meses. Conclusión : La cirugía de reparación de la insuficiencia tricuspídea moderada o severa, asociada a otras enfermedades cardíacas provee una buena recuperación sintomática, con excelente sobrevida alejada.

Abstract Background : Surgery for functional tricuspid valve insufficiency is indicated in cases of congestive heart failure usually associated to left heart valve diseases or as a concomitant surgery for other causes such as congenital or coronary disease. Aim : To assess and report the long-term results of tricuspid valve repair in adult patients in a regional cardiac surgery center in south Chile. Patients and Methods : Retrospective review of clinical and operative records of 114 patients aged 57.8 +/- 13 years (72 women) subjected to tricuspid reparative surgery concomitant with other cardiac procedures between 2009 to 2017. Results : In 45% of cases etiology was due to inactive rheumatic disease and 2.6% was due to endocarditis. 63% presented with atrial fibrillation and 75% were in NYHC CFIII. 15.8% had a previous cardiac valve surgery. Preoperative echocardiography showed severe tricuspid insufficiency in 56% of cases and pulmonary hypertension was severe in 39.5%. In all cases tricuspid repair was performed through the insertion of a semi rigid ring as a concomitant procedure for mitral repair/replacement in most cases, aortic valve replacement, surgical closure of an ASD, CABG surgery and the resection of cardiac tumors. Overall postoperative mortality was 16% due to multi-organic dysfunction in 6%, cardiac failure in 5% and cerebral hemorrhage in 4.3%. Mean long term follow up was 78.8+/- 7.2 months. Actuarial survival was 74% at 60 and 68% at 96 months. Conclusion: Surgical tricuspid valve repair for moderate to severe tricuspid insufficiency isolated or associated to other cardiac diseases provides a good symptomatic recovery, with an excellent long term survival.

Iatrogenic hemorrhage from left umbilical vein after cardiac surgery: An unusual complication.

Postoperative bleeding is a concern for all patients undergoing heart surgery, which could be due to surgical causes or coagulation disorder. The patients at risk for coagulopathy include those patients with complex or prolonged procedures, those exposed to preoperative anticoagulants and, to a lesser extent, patients with a preoperatively elevated prothrombin time and activated clotting time. However, intraabdominal bleeding after cardiac surgery is rare (0.3-2%). As the mortality rate of patients exposed to these complications is high (11-59%), timely recognition and prompt management is vital for patient's safety and for avoidance of postoperative complications. Here, we present a case of free intraabdominal hemorrhage as sequelae of pacing wire insertion in open heart surgery and its successful management.

Trans-esophageal echocardiography in off-pump coronary artery bypass grafting.

The two features of off-pump coronary artery bypass (OPCAB) grafting that lead to haemodynamic instability are, transient occlusion of the coronary arteries during distal anastomosis construction and displacement of the heart to provide access to the distal coronary arteries. The position of the heart as seen by trans-oesophageal echocardiography (TOE) can often provide an indication as to how much compression of the right or left ventricle has occurred. If either chamber is not filling, repositioning of the heart will be necessary. Close observation of the heart with TOE during periods of coronary occlusion may facilitate detection of worsening cardiac function as evidenced by weakening contraction, ventricular dilatation, or increasing mitral or tricuspid regurgitation. Haemodynamic change are more pronounced with displacement of the heart to access posterior than the anterior coronary arteries. Cardiac manipulations along with transient occlusion of coronary arteries during distal anastomosis may cause transient hypotension with increased filling pressures. TOE is helpful in this scenario as it helps to differentiate between cardiac dysfunction secondary to myocardial ischaemia (in which regional wall motion abnormalities will be present) from a much more common scenario where the increase in filling pressure is secondary to extra-cardiac compression and provides the ability to detect mitral regurgitation with a colour flow Doppler as well as assess the right heart function.

Impact of isolated coronary artery bypass grafting on non-organic tricuspid regurgitation severity

Moderate non-organic tricuspid regurgitation [TR] concomitant with coronary artery disease is not uncommon, Whether or not TR improves after pure coronary artery bypass grafting [CABG], however, is unclear. The aim of this study was to evaluate the effect of isolated CABG on moderate non-organic TR. This study recruited 50 patients [40% female, mean age: 65.38 +/- 8.01 years, mean left ventricular ejection fraction [LVEF]: 45.74 +/- 13.05%] with moderate non-organic TR who underwent isolated CABG. TR severity before and after CABG was compared. Pulmonary arterial systolic pressure [PAPs] > 30mmHg and LVEF < 50% were considered elevated PAPs [EPAPs] and LV systolic dysfunction, respectively. Presence of Q-wave in leads II, III, and aVF was considered inferior myocardial infarction [inf. MI]. Pre-operatively, 81.5% of the patients had EPAPs, 16% right ventricle [RV] dilation, and 50% left ventricle [LV] and 16% RV systolic dysfunction. TR severity improved in 64% after CABG, whereas it remained unchanged or even worsened in others [P value < 0.001]. Patients with inf. MI showed no improvement in TR, while patients without inf. MI had significant TR regression after CABG [P value= 0.050]. Improvement of TR severity after CABG was not related to pre-operative RV size and function, LV systolic function, or PAPs reduction. Although TR severity decreased remarkably after isolated CABG, a considerable number of the patients had no TR regression. In addition, only absence of inf. MI was significantly correlated to TR improvement after CABG. Further prospective studies with long-term follow-up needed to determine the other factors predicting TR regression after isolated CABG
