The Doppler echocardiographic characteristics of 70 prosthetic valves in 35 patients are reported. Twenty nine patients had a Björk-Shiley prosthesis in both mitral and tricuspid positions and six had Carpentier-Edwards valves in both sites. Five of the patients had abnormal tricuspid prostheses on the basis of clinical and echocardiographic criteria. Pulsed wave Doppler echocardiography was us...

I read with interest the article by Sung and colleagues about tricuspid valve replacement [1]. I agree with the authors that their reported results, although better than others, are still unsatisfactory. I think tricuspid valve replacement is an unfavourable surgery rather than catastrophic. The most important question in these operations is when to replace and not to repair the tricuspid valve...

Implantation of transvenous devices is a widespread procedure in clinical cardiology. It is well known that the presence of the electrodes in the cardiovascular system can induce fibrosis or fibrous adhesions between them and cause tricuspid regurgitation. Moreover there are suggestions that the placement of the electrode in the tricuspid orifice may also play a role in the development of tricu...

Echocardiographic studies have confirmed that normal splitting of the first heart sound is a result of mitral valve closure preceding tricuspid valve closure. This fits in with contraction of the left ventricle before the right, but the width of splitting is usually greater than would be expected from the known ventricular asynchrony. The importance of atrial systole, which initiates closure of...

The tricuspid valve leaflets and their annular attachments were recorded by two-dimensional echocardiography from a view of the right ventricular inflow tract obtained by placing the transducer at an intermediate position between the left ventricular apex and the left lower sternal border. The transducer was rotated, and recordings were made at 30 degrees rotational intervals around the circumf...

OBJECTIVES The aim of this study was to investigate the association between the pattern of incomplete tricuspid valve closure and the presence of tricuspid regurgitation and to identify factors that determine the severity of regurgitation associated with this pattern. BACKGROUND The incomplete tricuspid valve closure pattern (defined as apical displacement of the leaflets) has been described ...

THE DEVELOPMENT of mitral and aortic prostheses has allowed surgery for patients with pathology of multiple valves not otherwise correctable.1' 2 Experience with this type of surgery culminated in replacement of the tricuspid, mitral, and aortic valves during one operation in certain patients with severe rheumatic heart disease.3 The present report will describe the hemodynamic findings in eigh...

We report the surgical case of a 25-year old man admitted because of progressive dyspnoea and stabbing chest pain, who had undergone a pectus excavatum correction using a retrosternal strut 8 years previously. The computerized tomography scan showed that the right tip of the pectus bar had migrated across his right ventricle and tricuspid valve into the right atrium. Intraoperatively, it was co...

OBJECTIVES This study sought to: 1) determine the feasibility of using 3-dimensional transthoracic echocardiography (3D TTE) in patients with implantable cardiac resynchronization devices, pacemakers, and defibrillators to visualize the device leads in the right heart and their position relative to the tricuspid valve leaflets; 2) determine the prevalence of different lead positions; and 3) stu...
