Buja G - - 1991
An asymptomatic 19-year-old top-level athlete had electrocardiographic evidence of intermittent cardiac preexcitation and intermittent left bundle branch block. The electrophysiologic study demonstrated the presence of a direct accessory pathway and enhanced atrioventricular node conduction that resulted in infrahisian and intraventricular conduction disturbances. The echocardiogram disclosed tricuspid valve dysplasia.

The optimal management of pulmonary atresia with an intact ventricular septum in the neonate remains controversial. The introduction of balloon septostomy and prostaglandin has significantly reduced early mortality but early surgical intervention is necessary to obtain a more adequate pulmonary blood flow. Fourteen neonates with pulmonary atresia and an intact ...

Isolated congenital tricuspid valve stenosis is a rare entity. The modalities of definitive treatment have been surgical repair or replacement. We present the first reported patient with congenital tricuspid stenosis successfully treated by percutaneous balloon valvotomy. This appears to be an alternative to surgery when the anatomy, as demonstrated by ...
Ribeiro P A - - 1990
We performed percutaneous double balloon tricuspid valvotomy in four patients (36 +/- 12 years of age), with severe symptomatic rheumatic tricuspid stenosis and mild mitral valve disease. Two 9F Meditech balloon catheters, 15-20 mm diameter, were positioned simultaneously across the tricuspid valve and inflated up to five atmospheres pressure achieving ...

Palliative treatment was provided without complications by double balloon valvuloplasty of a stenotic porcine tricuspid valve in a patient with fungal endocarditis. With two 15 mm diameter valvulotomy balloons the peak tricuspid gradient decreased from 21 to 7 mm Hg and valve area increased from 0.3 to 1.2 cm2. After ...
Dietl C A - - 1990
A large intracavitary right ventricular tumor in a 24-year-old patient was considered nonresectable because it involved the interventricular septum, the free ventricular walls, and the tricuspid valve. Surgical palliation consisted of closure of the tricuspid and pulmonary valves, and the right atrium was anastomosed to the pulmonary artery bifurcation. The ...
Vogel M - - 1990
As no long-term results of a blind opening up of the pulmonary valve either by balloon valvoplasty or closed Brock valvotomy have been published, we examined the outcome of 12 patients with valvar pulmonary stenosis 17 +/- 5 (11-22) years after surgery. The Brock valvotomy had been carried out at ...

Doppler echocardiography was used to evaluate blood flow in the pulmonary artery in 14 patients 2 to 42 months (mean (SD) 17 (12) months) after a modified Fontan operation incorporating a direct atriopulmonary anastomosis. Preoperatively six patients had tricuspid atresia, six had a double inlet left ventricle, and two had ...
Gildein H P - - 1990
Four patients with complex cardiac lesions, who underwent successfully a Fontan type of operation are presented, each case representing a particular problem in surgical management. The first exhibited displacement of a trileaflet straddling and overriding left atrioventricular valve in addition to tricuspid atresia, while the second one had unilateral lung ...
Kaulitz R - - 1990
Following a Mustard's procedure, transoesophageal echocardiography allowed the visualization of all 4 pulmonary veins in 7/12 patients (mean age 14.8 years) and of three veins in a further 2 patients. Both upper pulmonary veins could be visualized consistently. No patient had an isolated pulmonary venous stenosis. In 9 patients in ...
Johnston S R - - 1990
Transesophageal echocardiography facilitates the evaluation of valvular repair in the operating room. The functional valvular morphology and degree of valvular regurgitation can be assessed before and after repair. This technique can also identify unsuspected findings--in this case, severe tricuspid regurgitation complicating cardiopulmonary bypass. We report a previously undescribed cause of ...
Miyazaki T - - 1990
A 70-year-old man who had been treated for tongue cancer began to suffer from repeated syncopal attacks. His electrocardiogram indicated complete atrioventricular block. A permanent pacemaker was implanted. He was well for about 2 years after which time he developed dyspnea, suffered from general fatigue, and then suddenly died. A ...
Balbi M - - 1990
One case of tricuspid valve endocarditis due to a catheter fragment inside the right chambers of the heart is described. The symptoms were fever, cardiac failure, splenomegaly and relapsing pneumonia. Blood culture was positive, revealing Staphylococcus aureus. A two-dimensional echocardiogram demonstrated a large vegetation on the tricuspid valve. The percutaneous ...
Czer L S - - 1990
Echocardiography with Doppler color flow mapping is a very useful intraoperative technique in patients undergoing mitral or tricuspid valve repair. In the patient who is a repair candidate, this technique can be used intraoperatively to answer important clinical questions: the severity of the regurgitation; the morphological basis of the regurgitant ...
Nair T - - 1990
Sixteen patients with coronary arteriovenous fistula (CAVF) were studied by two-dimensional echocardiography (2DE). Of these 12 had Doppler studies. In all, the diagnosis of CAVF was confirmed by aortic root or selective coronary angiography. In 8 patients, the 2DE findings suggested CAVF. Five patients had dilated main coronary arteries and ...
Anderson R H - - 1990
Dysplasia of the leaflets is a well-known integral part of Ebstein's malformation. It is less well-recognized that occasionally the septal leaflet may be completely absent and not simply displaced from its usual annular attachment. This may make it difficult to differentiate by echocardiography between Ebstein's malformation and the rare lesion ...
Restivo A - - 1990
The anatomy of the antero-septal commissure of the tricuspid valve and its relationship to the membranous part of the septum are described in 72 normal hearts from subjects ranging in age from 25 weeks gestation to 13 months. Three major patterns were found. According to whether the contiguous leaflets were ...
Martini B - - 1990
A P wave of 7.5 mm in lead I and 12.5 in V1 was detected in a 28-year-old man, with a progressive cardiomegaly since the age of 14 years. At last admission he had minor symptoms, and a systolic murmur consistent with tricuspid regurgitation. The electrocardiogram showed an extremely tall ...
Sade R M - - 1990
Tricuspid atresia is the third most common cyanotic cardiac malformation, seen in 1 per cent of children with congenital heart disease. Anatomic details in each patient can be elucidated by echocardiography. Surgical treatment initially is palliation, usually with aortopulmonary shunt. Definitive treatment is with a Fontan operation, in which the ...
Prayson R A - - 1990
We describe two unusual congenital anomalies of the tricuspid valve discovered incidentally at autopsy. One is an abnormal attachment of the tricuspid septal leaflet to one of two posterior papillary muscles with a concomitant fusion of the right ventricular septal and anterior papillary muscles in a patient with ectodermal dysplasia. ...
Wafae N - - 1990
An anatomical study of the tricuspid valve was carried out in 50 human hearts of both female and male individuals using a method of dissection which preserves the integrity of the valve. Morphometric criteria such as area of cusp, width of cusp base, relation between commissure depth and cusp depth ...
Lee C H - - 1990
We describe a previously unrecognised cause of an added diastolic heart sound. The patient had first-degree heart block and diastolic tricuspid regurgitation, leading to presystolic closure of the tricuspid valve and the production of a loud diastolic sound. Unlike previously described mechanisms for diastolic sounds, this sound was generated by ...
Abad C - - 1990
Tricuspid dysfunction appeared in a 47 year-old woman fifteen months after multiple valvular surgery, including aortic and tricuspid valvular replacement with Duromedics valves. At reoperation one of the leaflets of the tricuspid prosthesis was blocked with overgrown tissue from the native tricuspid annulus. The prosthesis was replaced with another Duromedics ...
Pye M - - 1990
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. ...
Tanaka M - - 1989
This report describes the case of a patient in whom Candida albicans tricuspid valve endocarditis was treated by excision of a large vegetation and partial tricuspid valvectomy without prosthetic valve replacement. In select patients, valve-sparing debridement may allow a long-term cure and may be the procedure of choice in the ...
Chopra H K - - 1989
Tricuspid regurgitation severity was assessed preoperatively with Doppler color flow mapping and these assessments were compared with surgical findings in 90 patients undergoing mitral or aortic valve replacement, or both. Group I (n = 52) required tricuspid valve annuloplasty because tricuspid regurgitation was judged intraoperatively to be severe; in Group ...
Res J C - - 1989
A rare complication is described, in three patients. The tined tip of a ventricular pacemaker electrode was entrapped in the chordae of the tricuspid valve and could not be removed by subtle manipulations in two patients. In one patient, the electrode was removed with partial rupture of the tricuspid valve. ...
Bridges N D - - 1989
The importance of pulmonary artery size and the value of a standardized pulmonary artery index (PAI) in predicting outcome after Fontan's repair have previously been reported and questioned. We retrospectively reviewed 29 patients undergoing modified Fontan repair at The Children's Hospital of Philadelphia to examine the relation between preoperative PAI ...
Mittal S R - - 1989
We describe a case of rheumatic tricuspid stenosis without involvement of the mitral valve. Rheumatic disease of the tricuspid valve is very rare in the absence of concomitant mitral valvar disease. We suggest that the closing pressure at the valve is not the only factor governing localization of the rheumatic ...
Kobayashi J - - 1989
Real-time flow imaging of pulmonary regurgitation (PR) by two-dimensional pulsed Doppler echocardiography was performed in 34 patients after repair of tetralogy of Fallot. The right ventricle and pulmonary artery were demonstrated in the parasternal short axis view and PR flow was visualized. The image was frozen when the velocity of ...
Squitieri C - - 1989
Retrograde right ventricular decompression through the tricuspid valve, by damaging or excising the valve, was attempted in five patients with pulmonary atresia, intact ventricular septum, and severely hypoplastic right ventricle. Two patients were neonates in critical condition, one of whom had received previous palliation with a shunt; the other neonate ...
Goel V - - 1989
The accuracy of a non-invasive estimation of systolic pulmonary artery pressure in 33 patients with ventricular septal defect and/or tricuspid regurgitation, by colour guided continuous wave Doppler was evaluated. The estimated pulmonary artery pressure correlated well with values obtained at cardiac catheterization (r = 0.93). Correlation was better in cases ...
Jureidini S B - - 1989
An infant with aortico-right ventricular (AO-RV) tunnel and critical pulmonary stenosis presented with severe distress at birth. We present the clinical, echocardiographic, and angiographic features, correlated with autopsy findings. Also we discuss the differentiation from other AO-RV communications and a theory for the embryogenesis. AO-RV tunnel should be considered in ...
Stárek A - - 1989
Using pulsed and continuous wave Doppler echocardiography, the author examined 359 subjects referred to ultrasound examination for a variety of reasons. Thorough examination of persons with morphologically unchanged valves revealed regurgitation in the tricuspid, pulmonary, mitral and aortic valves in 49.4%, 20%, 14.5% and 0.8%, respectively. The degree of regurgitation ...
Král J - - 1989
Using colour Doppler flow imaging technique (CDFI) 153 young healthy volunteers (80 M, 73 W) aged 23.9 +/- 1.4 years were studied for the prevalence and characteristics of regurgitations in morphologically normal valves. Regurgitation in normal pulmonary valve was found in 67.4%. Mid- to end-diastolic pulmonary regurgitation prevailed with the ...

A 21-year follow-up after tricuspid valve replacement (TVR) with a Starr-Edwards caged-ball prosthesis in a ten-year old boy is described. TVR is performed for Ebstein's anomaly, with strict indications in childhood. Despite the current preference for bioprostheses, good performance can be expected from the Starr-Edwards caged-ball valve.
Gewillig M - - 1988
Three patients with normal hearts and no pulmonary abnormality had neonatal tricuspid regurgitation causing cardiorespiratory distress and cyanosis. The signs of tricuspid regurgitation resolved over a few weeks. In the acute phase echocardiography showed gross dilatation of the right atrium and ventricle. The interatrial septum bulged into the left atrium ...
Mangschau A - - 1988
To study the effect of operation for left ventricular (LV) aneurysm on right ventricular (RV) performance, we studied 50 patients before operation with right heart catheterization, RV angiography, and radionuclide ventriculography. Forty patients were followed up and underwent the same investigations 10 +/- 4 months after operation. At baseline, regional ...
Kinney E L - - 1988
Few data are available regarding the prevalence and causes of false-negative auscultation (mis-auscultation) of aortic (AR), mitral (MR), or tricuspid regurgitation (TR), and there are no such data that are relevant when the patient's pretest probability of having regurgitation is unknown. The authors therefore studied 294 patients examined by pulsed ...
Datta B N - - 1988
Anatomically isolated aortic valve disease accounted for 1.1% of all and 5.2% of cardiac autopsies over a 20 year period. Among a total of 100 symptomatic cases, 52% had congenitally bicuspid, 43% had tricuspid and 5% had congenitally unicuspid valves. Nineteen percent had undergone fibrous sclerosis, including 1% unicuspid, 3% ...
Leung M P - - 1988
In this prospective study, 27 consecutive neonates suspected to be suffering from pulmonary atresia and intact ventricular septum underwent detailed two-dimensional echocardiographic examination before cardiac catheterization. Of the 27 neonates 25 had pulmonary atresia and intact ventricular septum and the remaining 2 had "functional pulmonary atresia" secondary to severe Ebstein's ...
Chin A J - - 1988
Transection of the main pulmonary artery and end-to-side anastomosis of the proximal pulmonary artery to the ascending aorta has been increasingly used in palliative surgery for cardiac malformations such as single ventricle with small outlet foramen (bulboventricular foramen) and hypoplastic left-heart syndrome. To evaluate pulmonary valve competence after this operation, ...
