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.

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.

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.

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.

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.

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.

Ruptura traumática de músculo papilar da valva tricúspide com forame oval patente adquirido e ruptura atrial direita oculta / Traumatic tricuspid valve papillary muscle case with concomitant acquired patent foramen ovale and covert right atrial rupture

Reparación de la insuficiencia tricuspídea: resultados a largo plazo en 114 pacientes / Repair of tricuspid valve insufficiency: long-term results in 114 patients

Resumen Antecedentes la reparación de la insuficiencia tricuspídea funcional está indicada en casos de insuficiencia cardíaca, generalmente, asociada a enfermedades de las válvulas cardíacas izquierdas y en algunos casos de enfermedad coronaria o cardiopatías congénitas. Objetivo : evaluar los resultados a largo plazo de la reparación tricuspídea en pacientes operados en la región centro sur de Chile. Pacientes y métodos : estudio retrospectivo de registros clínicos y operatorios en 114 pacientes con edad promedio 57.8 (DE 13) años (72 mujeres) sometidos a reparación tricuspídea asociada a otros procedimientos quirúrgicos entre 2009 y 2017. Resultados : la etiología de la insuficiencia tricuspídea fue debida a enfermedad reumática inactiva en 45% y a endocarditis infecciosa en 2.6%. 63% estaban en fibrilación auricular y 75% en capacidad funcional NYHC III. 15.8% tenían cirugía valvular cardíaca previa. El ecocardiograma mostró insuficiencia severa en 56% de los casos y había hipertensión pulmonar severa en 39.5%. La cirugía consistió en la implantación de un anillo semi-rígido en forma concomitante a reemplazo o reparación de lesión valvular mitral, reemplazo valvular aórtico, cierre de comunicación interauricular, cirugía coronaria o resección de tumor intra cardíaco. 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.

Ebstein's anomaly: "The one and a half ventricle heart"

Abstract Objective: Ebstein's anomaly remains a relatively ignored disease. Lying in the 'No Man's land' between congenital and valve surgeons, it largely remains inadequately studied. We report our short-term results of treating it as a 'one and a half ventricle heart' and propose that the true tricuspid annulus (TTA) 'Z' score be used as an objective criterion for estimation of 'functional' right ventricle (RV). Methods: 22 consecutive patients undergoing surgery for Ebstein's anomaly were studied. Echocardiography was performed to assess the type and severity of the disease, tricuspid annular dimension and its 'Z' score. Patients were operated by a modification of the cone repair, with addition of annuloplasty, bidirectional cavopulmonary shunt (BCPS) and right reduction atrioplasty to provide a comprehensive repair. TTA 'Z' score was correlated later with postplication indexed residual RV volume. Results: There was one (4.5%) early and no late postoperative death. There was a significant reduction in tricuspid regurgitation grading (3.40±0.65 to 1.22±0.42, P<0.001). Residual RV volume reduced to 71.96±3.8% of the expected volume and there was a significant negative correlation (rho −0.83) between TTA 'Z' score and indexed residual RV volume. During the follow-up of 20.54±7.62 months, the functional class improved from 2.59±0.7 to 1.34±0.52 (P<0.001). Conclusion: In Ebstein's anomaly, a higher TTA 'Z' score correlates with a lower postplication indexed residual RV volume. Hence, a complete trileaflet repair with offloading of RV by BCPS (when the TTA 'Z' score is >2) is recommended. The short-term outcomes of our technique are promising.

Thrombocytopenia after transcatheter valve-in-valve implantation: prognostic marker or mere finding?

Abstract Objective: To analyze the behavior of platelets after transcatheter valve-in-valve implantation for the treatment of degenerated bioprosthesis and how they correlate with adverse events upon follow-up. Methods: Retrospective analysis of 28 patients who received a valve-in-valve implant, 5 in aortic, 18 in mitral and 5 in tricuspid positions. Data were compared with 74 patients submitted to conventional redo valvular replacements during the same period, and both groups' platelet curves were analyzed. Statistical analysis was conducted using the IBM SPSS Statistics(r) 20 for Windows. Results: All patients in the valve-in-valve group developed thrombocytopenia, 25% presenting mild (<150.000/µL), 54% moderate (<100.000/µL) and 21% severe (<50.000/µL) thrombocytopenia. The platelet nadir was on the 4th postoperative day for aortic ViV, 2nd for mitral and 3rd for tricuspid patients, with the majority of patients recovering regular platelet count. However, the aortic subgroup comparison between valve-in-valve and conventional surgery showed a statistically significant difference from the 7th day onwards, where valve-in-valve patients had more severe and longer lasting thrombocytopenia. This, however, did not translate into a higher postoperative risk. In our study population, postoperative thrombocytopenia did not correlate with greater occurrence of adverse outcomes and only normal preoperative platelet count could significantly predict a postoperative drop >50%. Conclusion: Although thrombocytopenia is an extremely common finding after valve-in-valve procedures, the degree of platelet count drop did not correlate with greater incidence of postoperative adverse outcomes in our study population.

Síndrome carcinoide y compromiso valvular cardiaco, a propósito de 2 casos: Report of two cases / Tricuspid and pulmonary valve involvement in carcinoid syndrome

Carcinoid is a rare neuroendocrine tumor typically arising in the gastrointestinal tract that can cause heart valve involvement. We report two patients with carcinoid syndrome and tricuspid/pulmonary valve lesions. A 33-year-old male presenting with fatigue and weight loss: A tumor in the tail of the pancreas was found on an abdominal CAT scan. The percutaneous biopsy was informed as a carcinoid tumor. A trans-esophageal echocardiogram showed a tricuspid and pulmonary valve involvement, which was replaced surgically. The biopsy informed an extensive fibrous and myxoid degeneration of the valves. A 35-year-old male with a carcinoid syndrome and cardiac failure: An echocardiogram showed a severe tricuspid stenosis and severe pulmonary regurgitation. The patient was subjected to a double surgical valve replacement. The pathology report of the excised valve showed a deforming fibrous and myxoid valvulopathy.
