Objective To determine normal blood flow velocities across the fetal tricuspid valve (TV) at 11-13 weeks and 6 days of gestation and to examine the reproducibility of these measurements. Methods A prospective study involving 166 normal singleton pregnancies examined at 11-13 weeks and 6 days was carried out. Descriptive analysis of E- and A-waves` maximum velocities, E/A ratio, duration of the cardiac cycle (C) and diastole (D) and D/C ratio were calculated. Intraobserver and interobserver agreement analysis was performed in a subgroup of 12 cases. Results Average (+/- SD) flow velocities were: E-wave, 25.0 (+/- 4.6) cm/s; A-wave. 42.9 (+/- 5.9) cm/s; E/A, 0.58 (+/- 0.07); cardiac cycle, 390 (+/- 21.1) ms; diastole, 147 (+/- 18) ms and D/C, 0.38 (+/- 0.04). Significant correlation was observed between all parameters (except A-wave) and gestational age but not with nuchal translucency (NT). Intraclass correlation coefficients (interobserver, intraobsever examiner I and intraobserver examiner 2) were: E-wave, 0.53, 0.53 and 0.64; A-wave, 0.45, 0.46 and 0.49; cardiac cycle, 0.70, 0.79 and 0.84 and diastole, 0.63, 0.85 and 0.82, respectively. Conclusions The present study establishes normal Doppler parameters for blood flow across the TV at 11 - 13 weeks and 6 days and demonstrates that these parameters do not correlate with NT measurement and have good/moderate reproducibility.

Introdução: As principais operações para correção da anomalia de Ebstein baseiam-se na reconstrução da valva atrioventricular direita (AVD) em formato monovalvular, tendo resultados comprometidos pela necessidade de substituição ou alta reincidência de insuficiência valvar. Uma nova técnica foi desenvolvida, diferenciado-se das anteriores, pela correção anatômica da valva AVD, resultando na coaptação plena das válvulas no fechamento valvar. O objetivo deste estudo é avaliar a aplicabilidade dessa técnica, estudando os seus efeitos na evolução clínica, função da valva, restauração do ventrículo direito funcional e remodelamento reverso do coração no pós-operatório imediato (POI) e no pós-operatório em longo prazo (POL). Métodos: Estudo retrospectivo de 52 pacientes consecutivos, com idade média de 18,5±13,8anos, submetidos técnica do cone para correção da anomalia de Ebstein, entre novembro 1993 e dezembro de 2006, cujos principais detalhes cirúrgicos são: as válvulas anterior e posterior da valva AV direita são mobilizadas das suas implantações anômalas no ventrículo direito (VD), a borda livre desse conjunto é rodada no sentido horário para ser suturada à, previamente mobilizada...

Objetivou-se, neste trabalho, estudar a morfologia e vascularização do aparelho valvar das valvas mitral e tricúspide em corações humanos, comparando os resultados com aqueles obtidos em cães. A estereologia foi usada como ferramenta que permitiu avaliar os volumes entre as cúspides valvares, cordas tendíneas e mm. papilares, para o conhecimento das relações anatômicas desta estrutura. Foram analisados 15 corações humanos (10 homens e cinco mulheres, com idades variando de 9 a 77 anos) e 15 corações caninos (Canis familiaris - SRD 10 machos e cinco fêmeas, adultos). Os corações, sem alterações macroscópicas, foram dissecados, pesados e seu volume aferido com vistas a análise da morfologia. O estudo da irrigação e drenagem foi realizado por meio de moldes vasculares, em 10 corações de cada espécime. Fundamentados nos resultados obtidos, concluiu-se que as estruturas do aparelho valvar do coração canino e humano apresentam semelhanças tanto morfológicas como em relação a vascularização.; In this study we performed a comparative analysis of the morphology and vascularization of the valvar apparatus of the mitral and tricuspid valve of the human and canine heart.

Objetivo: Determinar os valores dopplervelocimétricos normais do fluxo através da valva tricúspide em gestações únicas, entre 11 e 13 semanas e seis dias. Examinar a reprodutibilidade dos parâmetros avaliados e sua correlação com variáveis clínicas maternas e obstétricas. Métodos: Estudo prospectivo envolvendo 166 gestações únicas, com desfecho normal, examinadas entre 11 e 13 semanas e seis dias, no período de fevereiro de 2006 a agosto de 2008. Foram aferidas as velocidades máximas das ondas E e A, duração do ciclo cardíaco completo e sua fase diastólica e calculadas as relações onda E/onda A e diástole/ciclo. Os valores normais foram descritos pelas respectivas médias e desvio-padrão. Para análise da reprodutibilidade desses parâmetros foi calculado o coeficiente de correlação intra-classes em 12 casos examinados por dois examinadores. Regressão linear simples e multivariada foram empregadas para examinar a correlação dos parâmetros dopplervelocimétricos entre si e com a idade gestacional, a medida da translucência nucal e variáveis maternas.

Objetivo: Determinar a proporção existente entre os segmentos do anel da valva tricúspide normal em humanos. Método: Foram estudados 30 corações de cadáveres humanos não formolizados, com menos de 6h de período ?post-mortem?, sem lesões congênitas ou adquiridas e com valvas tricúspides sem deformidades e continentes. A continência desta valva foi confirmada por injeção de água sob pressão no interior do ventrículo direito estando a valva pulmonar fechada. Foram realizadas fotos digitais da valva tricúspide com o anel valvar íntegro e após secção na comissura póstero-septal e retificação do anel valvar. Estas fotos contendo escalas milimetradas foram avaliadas por programa específico de computador. Foram feitas medidas computadorizadas do perímetro, segmento septal e segmento ântero-posterior do anel valvar íntegro. Nesta condição também foram feitas medidas da distância linear entre as comissuras ântero-septal e póstero-septal. Na condição de anel valvar retificado, foram realizadas medidas computadorizadas e manuais do perímetro e dos segmentos septal, anterior e posterior do anel valvar tricuspídeo. Compararam-se as medidas médias e as razões entre elas nas condições de anel íntegro e retificado. Compararam-se...

The tricuspid valve was studied in 143 subjects using two dimensional echocardiography. The groups studied were 40 normal subjects, 31 patients with mitral valve prolapse, 22 with clinically probable tricuspid valve prolapse, 20 with congestive cardiac failure, and 30 with miscellaneous cardiac conditions but no features of right heart disease. Using multiple views it was possible to record all three leaflets in 74.8% of cases and anterior and septal leaflets in 95%. Prolapse of the tricuspid valve was recognised in 13 patients: six (19.5%) of the group with mitral valve prolapse and seven (6%) of the remaining patients. Prolapse of all three leaflets was shown in one patient, anterior and septal prolapse in six patients, anterior and posterior in three patients, septal leaflet prolapse alone in two patients, and anterior alone in one patient. Two dimensional echocardiography allows definition of individual tricuspid leaflets and prolapse of any or all leaflets can be diagnosed. Tricuspid valve prolapse is commonly associated with prolapse of mitral valve leaflets but isolated cases are recognised.

This report describes a spectrum of M-mode and cross-sectional echocardiographic abnormalities in eight patients with infective endocarditis of the tricuspid valve. The M-mode echocardiogram of the tricuspid valve was abnormal in all but one patient in whom abnormal echoes were seen anterior to the tricuspid valve, in the right ventricular cavity and right ventricular outflow tract. Six patients had shaggy echoes on the tricuspid valve; and one patient showed multilayered echoes on the tricuspid valve which resembled a right atrial myxoma. Irregular diastolic fluttering of the tricuspid valve, indicative of ruptured chordae tendineae, was noted in three patients. The cross-sectional echocardiogram showed abnormal thick shaggy echoes on the tricuspid valve in all five patients on whom the procedure was performed. Contrast echocardiography confirmed the presence of tricuspid regurgitation in four patients. We conclude that echocardiography is useful in the diagnosis of tricuspid valve vegetations, and in detecting complications such as ruptured chordae tendineae and tricuspid regurgitation.

OBJECTIVE--To determine the changes of flow in the hepatic artery and portal vein of patients undergoing tricuspid valve repair together with mitral valve replacement. DESIGN--Non-randomised parallel group study. SETTING--Tertiary referral centre. PATIENTS--18 patients with mitral valve disease with or without tricuspid regurgitation (age range 46-73; six men) and six patients with coronary artery disease and normal left ventricular function (women age range 39-78; four men). INTERVENTIONS--Mitral valve replacement with or without modified De Vega repair of the tricuspid valve or coronary artery bypass surgery. MAIN OUTCOME MEASURES--Flow in the hepatic artery and portal vein as measured by duplex Doppler flowmetry before and two to four weeks after operation. RESULTS--Preoperative hepatic artery flow was less in patients with mitral valve disease than in patients with coronary artery disease (162.7(13.1) ml.min-1 v 242.5(6.6) ml.min-1, p < 0.05). Portal vein perfusion was significantly reduced only in patients with associated tricuspid regurgitation compared with (844(83) ml.min-1 v 1422(64) ml.min-1 p < 0.05). Hepatic perfusion was unaltered after operation in patients undergoing coronary artery bypass surgery (p > 0.05). Flow in the hepatic artery and portal vein was improved only in patients undergoing mitral valve replacement with associated tricuspid valve repair (p < 0.05). CONCLUSION--Abnormalities of hepatic perfusion can be measured non-invasively in all patients with mitral valve disease but especially in those with associated tricuspid regurgitation needing valve repair. These abnormalities improved two to four weeks after mitral valve surgery and tricuspid valve repair...

Objectives—To establish the prevalence of tricuspid valve abnormalities in children with a double discordant heart (or congenitally corrected transposition of the great arteries); to study the influence of the loading conditions induced by various surgical interventions on the right and left ventricle in patients with double discordance and an abnormal tricuspid valve; and to propose a rational surgical approach.
Methods—Case notes were reviewed of 141 consecutive patients admitted in the first year of life with various types of double discordance (intact ventricular septum (group 1), ventricular septal defect (group 2), ventricular septal defect and pulmonary obstruction (group 3)). A study group of 62 patients with an abnormal tricuspid valve was selected by cross sectional echocardiography. These were followed up through palliative and open heart procedures with grading of tricuspid regurgitation.
Results—Tricuspid valve abnormalities were more common in groups 1 and 2 (60% and 56%) than in group 3 (31%). Preoperative tricuspid regurgitation was more common in group 2 (90%) than in groups 1 and 3 (38% and 36%). Ten patients in groups 1 and 2 died in the neonatal period with severe tricuspid regurgitation, associated with coarctation of the aorta in 60%. Eight patients in group 1 had no surgery and are doing well...

Tricuspid valve surgery has been associated with a high operative mortality. This study reviewed 51 patients who underwent 53 tricuspid valve procedures between 1975 and 1989. Most patients (82%) had evidence of rheumatic heart disease. Twenty-six patients (51%) had 42 previous cardiac operations, most involving the mitral valve. Eighty-two percent of patients were New York Heart Association (NYHA) class III or IV preoperatively, and almost all patients had associated disease of other valves. The indication for operation was tricuspid regurgitation in 45 patients, infectious endocarditis in 4, and tricuspid stenosis in 2. The tricuspid abnormality was functional in 67% and organic in 33%. There were 32 tricuspid valve replacements, 20 annuloplasties, and 1 tricuspid valve excision. The hospital mortality rate was 11.8% (six patients). On statistical analysis, none of the perioperative variables were a significant risk factor for hospital mortality. Twenty-nine patients (51%) had postoperative complications. Postoperative functional status improved markedly with 80% in NYHA class I and 13% in class II. Long-term follow-up was attempted but was unsatisfactory in this transient, indigent population.

A 59 year old man underwent mechanical tricuspid valve replacement and removal of pacemaker generator along with 4 pacemaker leads for pacemaker endocarditis and superior vena cava obstruction after an earlier percutaneous extraction had to be abandoned, 13 years ago, due to cardiac arrest, accompanied by silent, unsuspected right atrial perforation and exteriorisation of lead. Postoperative course was complicated by tricuspid valve thrombosis and secondary pulmonary embolism requiring TPA thrombolysis which was instantly successful. A review of literature of pacemaker endocarditis and tricuspid thrombosis along with the relevant management strategies is presented. We believe this case report is unusual on account of non operative management of right atrial lead perforation following an unsuccessful attempt at percutaneous removal of right sided infected pacemaker leads and the incidental discovery of the perforated lead 13 years later at sternotomy, presentation of pacemaker endocarditis with a massive load of vegetations along the entire pacemaker lead tract in superior vena cava, right atrial endocardium, tricuspid valve and right ventricular endocardium, leading to a functional and structural SVC obstruction, requirement of an unusually large dose of warfarin postoperatively occasioned...

Uterine leiomyosarcoma is a rare malignancy and carries a poorer prognosis when compared to endometrial carcinoma. It has been observed to metastasize to all the major organs. It presents with symptoms of abdominal distension, vaginal bleeding and may pass unnoticed until an advanced stage in patients with leiomyomas. Surgery is a viable option in patients with disease limited to the uterus, but metastasis to the heart may require surgery to prevent acute and catastrophic complications. The case described here involves metastasis to the tricuspid valve, which caused severe tricuspid regurgitation in the setting of acute pulmonary embolism. Surgical resection restored cardiac function and stabilized the patient. This case illustrates a rare site of metastasis of leiomyosarcoma which required immediate intervention and resulted in a favorable outcome.

Résumé - Les données concernant la prise en charge chirurgicale de la maladie tricuspidienne reposent sur des études de cohortes à petite échelle et peu d’entre elles se sont intéressées aux résultats échocardiographiques et aux facteurs de risque de mortalité et de morbidité. Une étude de cohorte rétrospective descriptive et analytique fut effectuée pour analyser l’expérience de l’Institut de Cardiologie de Montréal concernant la chirurgie de la VT. Les données ont été récoltées à l’aide des dossiers médicaux. Durant la période 1977-2008, 792 PVT et 134 RVT furent effectués (âge médian : 62 ans). La mortalité opératoire était de 13,8%. Les taux de survie actuarielle à 5, à 10 et à 15 ans étaient respectivement de 67±2%, de 47±2% et de 29±2%. Au dernier suivi, de l’IT ≥3/4 était présente chez 31% des patients du groupe PVT et chez 12% des patients du groupe RVT (p<0,001). La classe fonctionnelle NYHA s’est améliorée significativement au dernier suivi par rapport à la période pré-opératoire (p<0,001). L’analyse de propension montre que par rapport à une PVT, un RVT est associé significativement à des taux de mortalité opératoire et tardive accrus, mais à moins d’IT ≥2/4 ou ≥3/4 lors du suivi. Cette étude montre que malgré le risque chirurgical substantiel associé à la chirurgie de la VT...

RESUMEN: 122 pacientes fueron intervenidos realizándose una doble reparación mitral y tricúspide por una enfermedad orgánica reumática. La reparación de la válvula mitral consistió en una anuloplastia con anillo flexible de Durán asociada a comisurotomía en 98 pacientes (80.3%) y anuloplastia flexible aislada en 24 pacientes (19.7%). La reparación valvular tricúspide se realizó en 78 pacientes (63.9%) mediante anuloplastia con anillo flexible y comisorotomía, y en 44 (36.1%) una anuloplastia con anillo flexible de Durán® aislada. La comisurotomia mitral cerrada previa y el tiempo postclampaje constituyeron los principales factores predictivos de riesgo. La mortalidad tardía ha sido de 94 pacientes (77.1%). La causa cardiaca (60.7%) ha sido el motivo más frecuente. Un total de 46 (37.7%) pacientes han precisado de una reoperación. La reparación simultanea mitral y tricúspide en la enfermedad reumática orgánica con anuloplastia de Durán® presenta unos resultados precoces satisfactorios. No obstante, la progresión de la enfermedad valvular es determinante en los resultados a largo plazo.; ABSTRACT: Between 1974 and 1999, 122 consecutive patients (mean age, 45.1 ± 12.5 years) underwent combined mitral and tricuspid valve annuloplasty with a flexible ring for rheumatic disease.

Dois casos de displasia da valva tricúspide são relatados neste trabalho. Os cães foram avaliados devido à fraqueza e presença de ascite. em ambos os casos, o exame ecocardiográfico mostrou insuficiência tricúspide e, em um deles, a inserção dos folhetos da valva tricúspide encontrava-se deslocada para baixo do ventrículo direito, caracterizando a anomalia de Ebstein. A terapia medicamentosa para insuficiência cardíaca congestiva foi iniciada, mas um dos animais veio a óbito subitamente alguns dias após o diagnóstico. O outro cão, apesar de inicialmente ter apresentado melhora significativa do quadro clínico, apresentou morte súbita. A necropsia dos animais revelou dilatação atrioventricular direita e folhetos tricúspides espessados. As características clínicas, métodos de diagnóstico e terapia medicamentosa são discutidas neste artigo.; Two cases of tricuspid valve dysplasia are reported.

We describe the case of a 38-year-old man with a history of metastatic testicular cancer who had undergone multiple thoracic surgical procedures, including tricuspid valve replacement with a bioprosthetic valve as a result of tricuspid involvement of his malignancy. He presented at our outpatient cardiology clinic with worsening fatigue, shortness of breath, and peripheral edema, investigation of which revealed severe tricuspid bioprosthesis stenosis with central regurgitation. Because of the patient's medical history, he was considered to be a high-risk surgical candidate. Therefore, transcatheter tricuspid valve-in-valve implantation of a 26-mm Edwards Sapien® valve was attempted through a transjugular approach. The procedure restored tricuspid valvar competence and substantially improved the patient's symptoms. We discuss the technical aspects of this case and briefly review the usefulness of the valve-in-valve technique in the tricuspid position.

We report a rare case of the absence of a posterior tricuspid valve leaflet. A male patient, aged 46, suffering from severe tricuspid valve regurgitation (TR) of unknown aetiology and atrial septal aneurysm was referred to our hospital for surgery. On surgical inspection, the posterior tricuspid valve leaflet and its subvalvular apparatus were completely absent and only the valve annulus was seen in the corresponding position. The anterior and septal leaflets were normal. We successfully reconstructed the tricuspid valve as follows: the head of an anterior papillary muscle was approximated to the ventricular septum (Sebening stitch). After the approximation of the centre of the tricuspid annulus of the anterior leaflet to the tricuspid annulus on the opposite side, a sizer of 29 mm in diameter was easily passed through the anterior orifice. The posterior orifice was closed with running sutures (posterior annulorrhaphy after Hetzer). Before these procedures, we attempted to reconstruct the tricuspid valve with a posterior annulorrhaphy alone; however, valve competence was insufficient. A Sebening stitch was necessary to improve the valve competence. Echocardiography showed TR grade 1 at the patient's discharge from hospital and TR grade 1 to 2 at the follow-up...

Echocardiographic findings in five patients with pulmonary embolism were studied. Tricuspid echocardiograms showed abnormalities in valve motion, that is a monophasic triangular wave during diastole in all the patients as well as an increased dimension of the right ventricle. An "a' dip of the pulmonary valve echocardiogram was also recognised in all five. Later tricuspid echocardiograms regained the normal M-shaped configuration. The monophasic triangular pattern of the tricuspid valve during diastole may be related to the shorter duration of tricuspid valve opening compared with that of the mitral valve. Tachycardia cannot explain this difference between tricuspid and mitral valve motion, which seems to be caused by a prolonged isovolumic relaxation time of the right ventricle resulting in a delayed opening of the tricuspid valve. These results were obtained by comparing these data with those of control subjects and patients with chronic right ventricular overloading resulting from atrial septal defect.

Two cases of tricuspid valve dysplasia are reported. Dogs were presented for evaluation of weakness and ascites. In both cases, echocardiography disclosed tricuspid insufficiency and, in one of them, tricuspid leaflets also were displaced down into the right ventricle, substantiating Ebstein's anomaly. Medical therapy for congestive heart failure was initiated. One of the dogs suddenly died shortly after diagnosis was established. Although the other dog recovered much better initially, sudden death also occurred. Post-mortem examinations showed right atrioventricular enlargement, and thickened tricuspid leaflets. Clinical features, diagnostic methods and medical therapy are discussed in this paper.
