Interferon alpha (IFNα) has immune stimulatory actions implicated in its pulmonary toxicities. We describe deterioration of idiopathic pulmonary fibrosis (IPF) associated with IFNα treatment for chronic hepatitis C in a 58 year old woman culminating in a fatal suspected acute exacerbation of IPF (AE-IPF). Caution should be exercised in the use ...

Mural inflammation has been shown to contribute to the development of plaque, with the α(V)β(3) integrin highly expressed in atherosclerotic plaques. We herein examined α(V)β(3) integrin expression as a function of carotid atherosclerosis formation in the apolipoprotein E-deficient (apoE(-/-)) mouse. Constrictive collars were placed around the left common carotid arteries ...

A 45-year-old lady developed significant symptomatic tricuspid valve stenosis due to a ventriculoatrial (VA) shunt, implanted in childhood for idiopathic hydrocephalus. This appeared to be a rare complication of a VA shunt. After detailed discussions in multidisciplinary meeting, she underwent successful treatment with a single balloon valvuloplasty. To date, she ...

The novel technique to repair a calcified tricuspid aortic valve using reconstruction of the valve cusps with autologous pericardium is described. The technique is based on the fact that in degenerative calcified stenosis of the tricuspid aortic valve, the cusp-free margins remain mostly uncalcified, even in very severe calcification, making ...

Chronic thromboembolic pulmonary hypertension causes right ventricular dilation with various degrees of tricuspid regurgitation, leading to right heart failure. Pulmonary thromboendarterectomy can substantially improve pulmonary hemodynamics and right ventricular dilation. The aim of this study was to determine whether the reduction of tricuspid regurgitation persists during follow-up. We studied 26 ...

OBJECTIVE: Absent pulmonary valve syndrome (APVS) is a rare congenital cardiac anomaly. Two variants of this anomaly are known. The postnatal outcome is generally poor. We report 2 patients who were referred to us for fetal echocardiography after abnormal findings on detailed sonography. We discuss the fetal echocardiographic features of ...

Mitral and tricuspid are increasingly prevalent. Doppler echocardiography not only detects the presence of regurgitation but also permits to understand mechanisms of regurgitation, quantification of its severity and repercussions. The present document aims to provide standards for the assessment of mitral and tricuspid regurgitation.

Congenital heart defects with a component of pulmonary stenosis are often palliated in childhood by disrupting the pulmonary valve. Patients often undergo subsequent pulmonary valve replacement (PVR) to protect the heart from the consequences of pulmonary regurgitation. In the presence of associated moderate functional tricuspid valve (TV) regurgitation, it is ...
Bai Yuan - - 2010
BACKGROUND: Valve replacement or repair is recommended in patients with tricuspid regurgitation when deterioration of their clinical status occurs as a consequence of right ventricular dysfunction. Percutaneous valve replacement was developed in recent years. To investigate the feasibility, effectiveness and long-term results of percutaneous tricuspid valve replacement, an experimental model ...

Prosthetic replacement of valves in children is limited by size constraints of the prosthesis and lack of growth potential. In specific situations like infective endocarditis, valve preservation is near impossible and in such instances alternatives are hard to get. Furthermore, in the tricuspid position the long-term results of both mechanical ...

Three-dimensional (3D) transthoracic echocardiography has advantages over traditional two-dimensional (2D) echocardiography in visualizing tricuspid valve morphology in Ebstein's anomaly. We describe the application of intra-operative 3D transesophageal echocardiography during a tricuspid valve repair procedure in a patient with Ebstein's anomaly. Intra-operatively three-dimensional transesophageal echocardiographic (3D TEE) data sets revealed morphology ...

We report on a premature neonate who presented with cyanosis soon after birth. She was found on echocardiography to have an unguarded tricuspid valve orifice associated with pulmonary valve atresia and an intact interventricular septum. Owing to the small-sized pulmonary arteries, she was initially managed conservatively with prostaglandin infusion, and ...

A 63-year-old male presented with sudden onset chest pain and dyspnoea following a kick to the praecordium while gelding a horse. Transthoracic echocardiography showed evidence of flail tricuspid valve leaflets, severe tricuspid regurgitation and a widely patent foramen ovale with a right-to-left shunt. Due to progressive severe systemic hypoxemia the ...

Congenital tricuspid valve disease (Ebstein's anomaly, tricuspid valve dysplasia) with severe tricuspid regurgitation and cardiomegaly is associated with poor prognosis. Fetal echocardiography can accurately measure right atrial enlargement, which is associated with a poor prognosis in the fetus with tricuspid valve disease. Fetal lung volumetric assessments have been used in ...

Double-outlet right atrium is a rare congenital cardiac anomaly previously described in association with atrioventricular canal defect. Straddling tricuspid valve is another uncommon anomaly that is almost always associated with a ventricular septal defect. We report the echocardiographic features of a newborn with double-outlet right atrium associated with pulmonary atresia, ...
Huang Shu-Chien - - 2009
OBJECTIVE: Tricuspid valve size is the major determinant of outcomes for patients with pulmonary atresia with intact ventricular septum. Lack of right ventricle-pulmonary artery continuity is associated with poor tricuspid valve growth (decrement in Z-value). However, most reports did not show evidence for disproportionate growth of the tricuspid valve after ...

The most common valves involved in systemic lupus erythematosus are the mitral and aortic valves. Although isolated tricuspid valve involvement is quite rare, the authors report such a case. A 42-year-old woman presented with exertional dyspnea and was found to have a cardiac murmur. Echocardiography showed a stenotic tricuspid valve ...
