Ubago J L - - 1981
The value of right ventriculography in the diagnosis of tricuspid insufficiency (TI) is often questioned because of 1) the high incidence of premature ventricular contractions (PVCs) during injections and 2) interference of the catheter in the valve closure mechanism. In 168 patients a commercially available, not preshaped, balloon-tipped catheter was ...

Protein-losing enteropathy occurred in a 7-year-old girl with tricuspid atresia, concordant ventriculo-arterial connexions and a relatively large hypoplastic right ventricle, one year after an atrio-ventricular type of Fontan operation by means of a valveless woven Dacron conduit. Severe conduit regurgitation and a marked enlargement of the hypoplastic right ventricle were ...
Skorton D J - - 1980
A case of infective endocarditis is reported in which a fistulous communication developed from the septal tricuspid valve leaflet, throught the membranous ventricular septum, into the non-coronary aortic cusp. From a nidus of infection in the uterus, the tricuspid valve was seeded, leading eventually to the fistula. The particular course ...
Pepper J R - - 1980
A case is reported in which acute tricuspid regurgitation developed in a child with a ventricular septal defect resulting in a left ventricular-right atrial shunt. This was successfully treated by closure of the defect and tricuspid valve replacement. The anterior leaflet of the tricuspid valve was almost completely destroyed by ...
Becker A E - - 1980
Four hearts are described in which the right atrioventricular valve, draining a morphologically right atrium, straddled and overrode a septum between a right-sided chamber of left ventricular morphology and a left-sided chamber of right ventricular morphology. The degree of override varied between the straddling valve and was committed by 20-45% ...

Rupture of a papillary muscle of the tricuspid valve is a rare occurrence, and nontraumatic rupture is still rarer. We describe a 26-year-old male with primary pulmonary hypertension presenting with severe dyspnea and paroxysmal nocturnal dyspnea following spontaneous rupture of the septal papillary muscle of the tricuspid valve. The clinical ...
Marcelletti C - - 1980
Reported herein is the case of a patient with an almost imperforate form of Ebstein's anomaly of the tricuspid valve and a small muscular ventricular septal defect through which the left ventricle communicated with the right ventricular outflow tract. This particular anatomy facilitated the successful execution of a Fontan operation. ...
Salazar J - - 1980
The echocardiographic findings in a case of ventricular septal defect with aneurysm of the membranous septum and a parachute mitral valve, are analyzed. An abnormal linear echo was recorded within the left ventricular outflow tract and in the aortic root, and in close relationship with the tricuspid valve. No abnormal ...
Lim K O - - 1980
The mechanical properties and ultrastructure of normal human tricuspid valve chordae tendineae were examined. Mechanical studies showed that these chordae exhibited less extensibility than normal mitral valve chordae of comparable size. The non-linear stress-strain curve of the tricuspid chordae, however, can be attributed to their microstructure. Under scanning electron microscopy ...

Right heart catheterization was carried out on 14 patients with pulmonic regurgitation using intracardiac phonocardiography. All the patients showed pulmonic regurgitant murmur in the right ventricular outflow tract. In addition, seven out of the 14 patients showed mid-diastolic and presystolic murmurs maximally in the outflow tract of the right ventricle. ...
Bloom K R - - 1979
The association of either mitral or tricuspid stenosis with endocardial cushion defects has been well recognized pathologically but is infrequenctly diagnosed clinically. M mode echocardiographic features such as markedly disproportionate ventricular size, abnormal mitral or tricuspid diastolic echoes or failure to define adequately an atrioventricular (A-V) valve are strongly suggestive ...
Bardy G H - - 1979
A case of traumatic tricuspid insufficiency leading to right atrial enlargement and to a patent foramen ovale with right to left shunting is presented. Six similar cases previously reported are reviewed. The time course of clinical deterioration was related to the type of tricuspid valve damage incurred. Papillary muscle rupture ...
Ando H - - 1979
M-mode echocardiography on a fifty-eight year old female with Uhl's anomaly showed several characteristic findings, which were considered to be useful in differentiating Uhl's anomaly from Ebstein's. Those findings were normal tricuspid diastolic closing velocity, the relatively early tricuspid valve opening, easy visualization of the tricuspid valve in usual position ...
Semb B K - - 1979
The rare congenital anomaly of pulmonary valve stenosis and massive tricuspid valve insufficiency with intact ventricular septum is a lethal condition without reported survival after attempted treatment. In a neonate suffering from this syndrome, the pulmonary valve stenosis was relieved by rupturing the fused valve with a balloon catheter introduced ...
Takahashi O - - 1979
An echocardiographic pattern of normal tricuspid valve motion in a patient with tricuspid atresia, and pulmonic valve motion in a patient with transposition of the great vessels and pulmonary atresia were documented. The recordings of the valve motion resulted in an initial erroneous diagnosis. Although M-mode echocardiography is very useful ...

This paper deals with the anatomic differences between single ventricle and small outlet chamber, straddling tricuspid orifice and valve, and displaced tricuspid orifice and valve. In single ventricle, both atrioventricular orifices enter a chamber which contains the sinuses of both definitive ventricles, while a small outlet chamber represents the definitive ...
Mintz G S - - 1979
M-mode and two-dimensional echocardiographic evaluation of infectious endocarditis and its complications was reviewed. In 21 consecutive patients with clinical endocarditis, 22 valves were involved (12 aortic, 5 mitral and 5 tricuspid). M-mode echocardiography detected vegetations in 10 patients (four aortic, two mitral and four tricuspid) and detected complications of endocarditis ...
Ciaravella J M JM - - 1979
Two patients with a rare form of double-chambered, double-outlet right ventricle (DORV) are described. Both patients had associated pulmonary stenosis, ventricular septal defect, and a large tricuspid valve whose chordal attachments crossed the right ventricular outflow tract. The angiocardiographic, echocardiographic, and operative findings were distinctive. The right ventricle was positioned ...
Coto E O - - 1979
Two pathological specimens are described in which a bizarre distortion of atrioventricular and ventriculoarterial relations existed. In both cases anterior and leftward displacement of the tricuspid valve coexisted with rightward displacement of the infundibular regions and semilunar valves. Abnormal expansion of the AV canal, possibly secondary to malrotation of the ...
Thiene G - - 1979
Conotruncal anomalies associated with atrioventricular (AV) canal defects are more common than is generally appreciated on clinical grounds. Among 39 specimens of AV canal malformations, 13 (33%) presented with conotruncal abnormalities: a complete form of AV canal has been observed in all. 5 cases exhibited visceral situs solitus, 5 situs ...
Mintz G S - - 1979
A patient is described with tricuspid valve endocarditis in whom the vegetation interfered with valve closure resulting in marked wide splitting of the first heart sound. M-mode and two-dimensional echocardiographic studies detected the presence of a vegetation. Simultaneous phonocardiographic and echocardiographic studies documented the marked delay in tricuspid valve closure ...
Anderson K R - - 1979
The rare and curious congenital malformation of the tricuspid valve known as Ebstein's disease or Ebstein's anomaly has been a subject of considerable interest to the cardiologist and the morphologist since its first description by Wilhelm Ebstein in 1866. With the evolution of various surgical techniques for the correction of ...
Tabry I F - - 1979
Corrective operations were attempted in 10 patients with straddling atrioventricular valve (SAVV), and successful palliative operations were performed in another nine patients. SAVV occurred as a part of five different cardiac complexes, and three anatomic types were encountered. The SAVV was a tricuspid valve in eight patients, right atrioventricular valve ...
Zuberbuhler J R - - 1979
The structure of the tricuspid valve in 14 cases of Ebstein's malformation is described and compared with that in the normal heart. The anomalous hearts showed a spectrum of malformation, varying from minimal displacement of the adjacent parts of the septal and inferior leaflets of the tricuspid valve to presence ...
Lewis B S - - 1979
The echocardiographic features of pulmonary valvar atresia with intact ventricular septum are described. The pulmonary valve fails to open during systole: there is a large pre-systolic 'a' wave dip, but the pulmonary valve membrane then returns to its closed diastolic position where it remains for the remainder of the cardiac ...
Anderson K R - - 1978
The tricuspid valve is left-sided in congenitally corrected transposition of the great arteries and other cardiac malformations in which the ventricles are inverted. In an anatomical study of 20 hearts with ventricular inversion, nine were found to have Ebstein's anomaly of the left-sided tricuspid valve. These included eight with congenitally ...

Thirteen (16 percent) of 80 patients with tetralogy of Fallot and pulmonary atresia undergoing corrective operations between Jan. 1, 1967, and Jan. 1, 1978, died in the hospital. The hospital mortality rate was 13 percent (10 deaths) among the 77 patients with confluent right and left pulmonary arteries. The risk ...
Ports T A - - 1978
Nine patients with Ebstein's anomaly of the tricuspid valve were studied by two-dimensional echocardiography, using the standard long and short axis views as well as the apex four chamber view. With this latter view, the displacement of the tricuspid valve into the right ventricle was clearly seen in all nine ...
Silverman N H - - 1978
A case of tricuspid atresia with unusual echocardiographic findings is presented. The echocardiogram was successful in defining great artery interrelationships, ventricular looping, and cavity sizes. An echo pattern resembling the motion of a small tricuspid valve was observed; this was proven to be spurious at catheterization and necropsy. Caution should ...
Holt R G - - 1978
Cineangiocardiograms from 2 patients with carcinoid syndrome and cardiac involvement were reviewed. Gross and microscopic pathology specimens were available for 1 case. Both patients exhibited tricuspid valvar stenosis and insufficiency. The area of the pulmonic valve was similar in both with narrowing of the annulus and tapering toward the valve ...
Johnson G L - - 1978
