Tricuspid regurgitation

Hidehiro Kaneko, Michael Neuss, Jens Weissenborn, Christian Butter
Functional mitral regurgitation (MR) is common in patients with heart failure and left ventricular (LV) dysfunction. MitraClip (MC) is a novel therapeutic option for patients with high-risk MR. Similar to LV dysfunction, right ventricular dysfunction (RVD) is an important predictor of patients with heart failure. We aimed to clarify the effect of RVD on outcomes of functional MR and LV dysfunction after MC implantation. We examined 117 patients with severe functional MR and reduced LV ejection fraction (≤40%) treated with MC...

There has been revival of in interest in exercise testing of the pulmonary circulation for the diagnosis of pulmonary vascular disease, but there still is uncertainty about body position and the most relevant measurements. Doppler echocardiography pulmonary hemodynamic measurements were performed at progressively increased workload in 26 healthy adult volunteers in supine, semi-recumbent and upright positions which were randomly assigned at 24 hours intervals. Mean pulmonary artery pressure (mPAP) was estimated from the maximum tricuspid regurgitation jet velocity...

Bronchopulmonary dysplasia (BPD) is often complicated by pulmonary hypertension (PH). We investigated three biomarkers potentially suitable as screening markers for extremely preterm infants at risk of BPD-associated PH. In this prospective observational cohort study conducted in a tertiary neonatal intensive care unit, 83 preterm infants with BPD born <28 weeks gestation and still inpatients at 36 weeks corrected age received an echocardiogram and blood tests of B-type natriuretic peptide (BNP), troponin I, and YKL-40...

The anatomic causes for fetal right atrial dilatation with tricuspid regurgitation include Ebstein anomaly, tricuspid dysplasia, unguarded tricuspid orifice, and Uhl anomaly. Unguarded tricuspid orifice is characterized by complete or partial agenesis of the tricuspid valvular and subvalvular structures. It is commonly associated with pulmonary atresia. Its prenatal diagnosis is usually associated with unfavorable prognosis. We present a prenatally diagnosed case of fetal unguarded tricuspid orifice with description of its diagnostic workup, along with a review of literature, to enhance the understanding of this rarely reported entity...

An 84-year-old man with cardial senile amyloidosis and severe tricuspid regurgitation was referred for right sided heart failure symptoms. The patient was scheduled for a percutaneous treatment due to the prohibitive risk of surgery. Two MitraClips were implanted using a transjugular approach with successful echocardiographic and clinical results. This case shows the rational of the procedural with a bicuspidalization of the valve demonstrated at the three dimensional transesophageal echocardiography.

Hypoplastic right heart syndrome is a rare cyanotic congenital heart disease with under-development of the right ventricle, tricuspid, and pulmonary valves leading to right-to-left shunting of the blood through inter-atrial septal defect. Perinatal mortality is high with very few patients surviving to adulthood without corrective surgery. This report describes a 26-year-old young woman, who had recurrent abortions and stillbirths and detected to have marked cyanosis with hypoplastic right heart, sub-arterial ventricular septal defect, absent pulmonary valve, non-compaction of the left ventricle, and bicuspid aortic valve with aortic regurgitation...

BACKGROUND: Red blood cell distribution width (RDW) is a quantitative measurement of anisocytosis. RDW has prognostic value in humans with different cardiovascular and systemic disorders, but few studies have investigated this biomarker in dogs. OBJECTIVES: To compare the RDW in dogs with precapillary and postcapillary pulmonary hypertension (PH) and a control population of dogs and to correlate RDW with demographic, echocardiographic, and laboratory variables. ANIMALS: One hundred and twenty-seven client-owned dogs including 19 healthy dogs, 82 dogs with myxomatous mitral valve disease (50 dogs without PH and 32 dogs with postcapillary PH), and 26 dogs with precapillary PH...

BACKGROUND: Right ventricular (RV) dysfunction and tricuspid regurgitation (TR) may coexist with aortic stenosis. The aim of this study was to assess the association between RV dysfunction, TR, associated comorbidities, and outcomes following transcatheter aortic valve replacement (TAVR). METHODS: A retrospective analysis was conducted of baseline and 6-month clinical and echocardiographic parameters, including TR grade, RV size (grade, end-diastolic and end-systolic areas, annular diameter), and function (grade, tricuspid annular plane systolic excursion [TAPSE], fractional area change, Tei index), in 519 consecutive TAVR patients...

OBJECTIVES: To assess the natural history and outcome of fetal pulmonary stenosis [PS] detected at 14 to 16 weeks gestation. METHODS: This is a retrospective study, in the years 2004-2015, with serial follow up during pregnancy. Patients referred for complete early fetal ultrasound including all fetal systems and a fetal echocardiogram. Ninety seven percent of the women were low risk, and 3% had risk factors such as maternal type 1 diabetes mellitus, exposure to teratogenic drugs or anomalies in previous pregnancies or in other family members...

Background/Aims: Pulmonary endarterectomy (PEA) is the gold standard for treating chronic thromboembolic pulmonary hypertension (CTEPH) in Western countries. The aim of this study was to investigate the long-term outcomes of performing PEA on CTEPH patients in comparison with medical therapy at a single Korean center. Methods: This retrospective study included 88 CTEPH patients. These patients were classified into the PEA group (n = 37) or non-PEA group (i.e., medical therapy; n = 51)...

AIMS: Pulmonary hypertension (PH) is associated with mortality after transcatheter aortic valve implantation (TAVI). However, diagnosis based on tricuspid regurgitant velocity (TRV) is often inaccurate and unreliable. The updated PH guidelines introduced a PH probability grading implementing additional PH signs on transthoracic echocardiography (TTE), from which we aimed to analyse its effects on clinical outcomes in patients undergoing TAVI. METHODS AND RESULTS: We included 591 consecutive patients (mean age 80...

BACKGROUND AND OBJECTIVES: The aim of the study is to evaluate the long-term results after a surgical repair of Ebstein's anomaly. SUBJECTS AND METHODS: Forty-eight patients with Ebstein's anomaly who underwent open heart surgery between 1982 and 2013 were included. Median age at operation was 5.6 years (1 day-42.1 years). Forty-five patients (93.7%) demonstrated tricuspid valve (TV) regurgitation of less than moderate degree. When the patients were divided according to Carpentier's classification, types A, B, C, and D were 11, 21, 12, and 4 patients, respectively...

We present the primary report of a paediatric patient who had placement of the MitraClip device for severe functional mitral regurgitation. The patient was a 14-year-old boy with symptomatic end-stage non-compaction type cardiomyopathy secondary to a mitochondrial cytopathy. He had severe mitral regurgitation, tricuspid valve regurgitation, a severely dilated LV with apical non-compaction, severe LV dysfunction and severe pulmonary hypertension. Despite optimal medical therapy he developed progressive symptoms of congestive heart failure and he was not a candidate for an assist device or cardiac transplantation...

Pulmonary hypertension is a pathophysiological state hemodynamically defined as the increase of the mean pulmonary arterial pressure above 25, or 30 mmHg at rest, measured by catheterization of the right heart. Laboratory findings usually reveals polycythemia, the ECG right ventricle hypertrophy, and x-ray characteristic of diseased branches (echocardiography and biomarkers such as B-type natriuretic peptide (BNP) and N-terminal pro-BNP hormones are potentially helpful tools in identifying PH). Echocardiography can be found the increase of the right atrium and ventricle, right ventricular hypertrophy, abnormal contraction of the interventricular septum, left ventricular diastolic dysfunction and decreased left ventricular size, with reduced volumes of systole and end diastole...

OBJECTIVES: Favourable outcomes in the repair of Ebstein's anomaly are predicated on tricuspid valve competence, right ventricular function and presence of arrhythmia. We report our experience with a single-stage, three-fold repair of Ebstein's anomaly, namely, cone reconstruction of the tricuspid valve supplemented by bidirectional cavopulmonary anastomosis and right atrial electrocautery maze. METHODS: From 2010 to 2014, 37 consecutive patients with Ebstein's anomaly, median age 17...

BACKGROUND: Options for cardiac valve replacement in children are limited to fixed-diameter prostheses that do not accommodate for somatic growth. An externally stented bovine jugular vein graft has been modified for surgical valve replacement in pediatric patients, with the intention of subsequent valve expansion in the catheterization laboratory as the child grows. METHODS: Pediatric patients at a single institution who underwent surgical implantation of an expandable bovine jugular vein valve between 2010 and 2014 were reviewed retrospectively...
