A transjugular approach was successfully used for concurrent mitral-aortic and mitral-tricuspid valvuloplasty in one patient each. This approach simplifies antegrade transvenous aortic valve dilatation in rheumatic aortic stenosis. Advantages obtained by transjugular tricuspid valvuloplasty are easy crossing of the tricuspid valve and stable balloon position, co-axial with the tricuspid orifice.
Narine K K - - 2000
We report the case of a 62-year-old woman in whom carcinoid disease had been diagnosed 6 years earlier. She subsequently developed tricuspid and pulmonary valve disease. Both valves were incompetent and mildly stenotic. The tricuspid valve required surgery; the pulmonary vaive was explored but not treated. Valve surgery in patients ...
Bedynek J L JL - - 2000
We report the cases of 2 patients whose tricuspid aortic valves were found to have partial commissural fusion. Both patients experienced complications that were probably related to this abnormality: bacterial endocarditis in 1 instance and a lacunar stroke in the other. In order to illustrate the similarity of physical findings, ...

Tricuspid valve dysfunction occurs frequently in patients with rheumatic heart disease and is usually manifested as functional or organic tricuspid regurgitation. Rheumatic tricuspid stenosis is less common and occurs characteristically in the presence of concomitant mitral valve disease. In this report, we describe the clinical and echocardiographic findings in a ...
Shibata Y - - 1999
A 73-year-old woman with congenital isolated organic tricuspid regurgitation was reported. She had neither the history of chest trauma nor rheumatic fever nor the evidence of infective endocarditis. The patient was successfully treated with a bioprosthetic valve replacement in tricuspid position. Operative findings revealed hypoplastic anterior leaflet and relatively large ...
Roques F - - 1999
Patients with valvular myxoma are usually candidates for surgery because of the high incidence of life-threatening embolism. In some cases, the tumor is sessile or presents with a large peduncle: complete excision may then lead to valve replacement. We report two cases of atrioventricular valve myxoma where replacement was avoided. ...
Aoyagi S - - 1999
A rare case of isolated tricuspid regurgitation (TR) in a 65-year-old man is presented. Echocardiography revealed enlargement of the right atrium, dilatation of the tricuspid valve annulus without thickening or prolapse of the leaflets, and an intact atrial septum. No downward displacement of the tricuspid septal leaflet was observed by ...

Chest ...
Geggel R L - - 1999
We report a 52-year-old adult with Ebstein's anomaly associated with severe valvar pulmonary stenosis, secundum atrial septal defect, polycythemia, hypoxemia, and severe exertional limitations. Balloon pulmonary valvuloplasty relieved the valvar obstruction, reduced the degree of tricuspid regurgitation and polycythemia, and improved systemic oxygenation and exercise abilities. Use of this technique ...
Lessana A - - 1999
Although many surgical procedures have been proposed to reduce the size of a left atrium, their effectiveness is not well established. We present a case of mitral and tricuspid valve insufficiency with a giant left atrium. Partial heart autotransplantation was used in a mitral and tricuspid valve operation with a ...
Waldman J D - - 1999
Of the "five T's" of cyanotic congenital heart disease--tetralogy of Fallot, TGA, TAPVC, truncus, and tricuspid valve abnormalities (tricuspid atresia, stenosis, and displacement)--the first and last are commonly associated with diminished PBF. The four features that comprise tetralogy of Fallot--right ventricular hypertrophy, VSD, overriding aorta, and subpulmonary stenosis--are all secondary ...

METHODS: A historical cohort study was conducted in a clinical obesity-management practice. A total of 164 patients (88% women) ...
Dindar A - - 1999
Division of the morphologically left atrium is a rare abnormality, constituting around 0.1% of congenital heart disease. It may coexist with other cardiac abnormalities, and this association may obscure its recognition. We report an uncommon association with tricuspid atresia and discordant ventriculo-arterial connections, the latter dominating the clinical picture. Accurate ...
Yamashita C - - 1998
We describe the case of 35-year old woman who had undergone radical surgery to correct Tetralogy of Fallot malformation at the age of nine admitted to our hospital because of palpitation and exertional dyspnea.
