A 42 year old woman with symptomatic double chambered right ventricle had the additional features of an anomalous left anterior descending coronary artery and attachment of the tricuspid valve to the area of subinfundibular stenosis which precluded conventional repair. A non-valved Dacron conduit was used to bypass the obstruction. The ...
Coralli R J - - 1985
A patient with a ruptured sinus of Valsalva aneurysm (RSVA) demonstrated an unusual two-dimensional echocardiographic manifestation of this entity. A discrete mass of echoes, appearing attached to a posterior leaflet of the tricuspid valve, moved to and fro into the right ventricle during diastole and into the right atrium in ...
Zahler R - - 1985
Echocardiography is a key diagnostic tool in the recognition of pericardial tamponade. A 56-year-old man in whom severe dyspnea developed 22 days after cardiac surgery is described. Echocardiography suggested tricuspid valve disease but showed no pericardial abnormalities. Catheterization revealed functional stenosis of a normal tricuspid valve caused by loculated serous ...
Muster A J - - 1985
The criterion for the diagnosis of functional atresia of a patient semilunar valve is met when the pressure in a ventricle remains lower than that in the related great artery throughout systole so that no forward flow can occur. Functional pulmonary valve atresia has been well recognized in infants with ...
Folger G M GM - - 1985
Hypoplasia of the right ventricle occurring as an isolated abnormality is an uncommon cause of cyanotic congenital heart disease. Its presentation in the newborn may mimic the ductus dependent and less stable right ventricular hypoplasias such as tricuspid atresia and pulmonary atresia. However, the natural history of this abnormality contrasts ...
Grande A M - - 1985
The occurrence of valvular lesions alone as a result of nonpenetrating trauma is not common. Most reports have shown mainly isolated rupture of the aortic valve, whereas, reports of traumatic rupture of the tricuspid valve without associated injuries are rare in the literature. At our center, three patients were treated ...

Data from 51 patients with small right ventricle who underwent a definitive repair were analyzed retrospectively. The repair was considered complete (29 patients) when it resulted in relief of the right ventricular outflow tract obstruction by closure of intracardiac (atrial septal defect) and extracardiac (when present) shunts. The repair was ...
Trowitzsch E - - 1985
Critical pulmonary stenosis or atresia with intact ventricular septum represents a congenital cardiac lesion for which the long-term prognosis appears to depend partly on the size of the right ventricle. Thus, the capability of noninvasive assessment of right ventricular size to predict operative outcome was examined in 15 infants (aged ...
Brown A K - - 1985
A 78 year old woman with congestive cardiac failure developed pulmonary embolism. Cross sectional echocardiography detected an undulating fusiform mass attached to the lateral wall of the right atrium and protruding through the tricuspid valve. Serial cross sectional echocardiograms showed a reduction in the size of the mass, and by ...
Bowles C R - - 1985
Dense opacification of coronary arteries in pediatric coronary cineangiograms led to the observation of a small branch of the main septal artery that is directed into the right ventricle and gives a fan-shaped blush. This vessel passes through the moderator band and into the anterior papillary muscle, which anchors the ...
Skjaerpe T - - 1985
Fifty-one patients underwent Doppler studies of tricuspid flow and 2-D derived M-mode studies of the inferior vena cava (IVC) during upper extremity contrast injections. Tricuspid regurgitation (TR) was diagnosed with Doppler when reverse flow in systole was recorded at and behind the closure level of the tricuspid valve. TR was ...

The technique of tricuspid commissurotomy is based on principles different from those employed in mitral valve commissurotomy. In performing tricuspid commissurotomy, it is essential to identify and split the fan chordae, which are always fused and which clearly delineate the fused commissures. Failure to do this can result in an ...

Eighty-two normal fetuses were scanned from 18 to 41 weeks of gestation. The following M-mode measurements were correlated with the abdominal circumference: diastolic biventricular outer (r = 0.951) and inner (r = 0.948) dimensions; diastolic right (r = 0.942) and left (r = 0.925) internal dimensions; tricuspid (r = 0.916) ...
Ottenkamp J - - 1985
An anatomic study of 28 heart specimens with tricuspid atresia showed 15 hearts with ventriculoarterial concordance and a right-sided anterior outlet chamber. Of these 15 hearts, 12 showed evidence of restricted pulmonary blood flow. In eight of these 12 specimens, an anterior deviation of the outlet septum, relative to the ...
Gowda S - - 1985
Two patients with biopsy-proven amyloid restrictive cardiomyopathy were presented. Both cases showed ventricularization of an elevated right atrial pressure wave form in absence of tricuspid regurgitation. Possible explanations for this finding as well as its clinical implications are discussed. This observation indicates that ventricularization of right atrial pressure wave form ...

Angiocardiographic appearance of a criss-cross heart with straddling tricuspid valve has been presented. Atrial situs was normal and the right atrium was connected to the morphological right ventricle situated superiorly and to the left of the left ventricle. The left atrium was connected to the morphological left ventricle situated inferiorly ...
Painvin G A - - 1984
An extracardiac, transepicardial approach to the atrioventricular junction, allowing selective cryoablation of the bundle of His, was performed in 10 mongrel dogs. This technique appears to minimize dissection complications, the risk of endocardial damage, and injury to the tricuspid valve, which are reported with endocardial cryoablation. All dogs survived this ...
Loeber C P - - 1984
Cardiac flows measured by the Doppler technique and invasive methods correlate well, but no prior study has correlated Doppler flows obtained distal to the four cardiac valves in the same individual. The purpose of this investigation was to measure the four flows in normal subjects using the range-gated pulsed Doppler ...
Gussenhoven E J - - 1984
The M-mode echocardiographic diagnosis of overriding tricuspid valve rests on the ability to demonstrate simultaneously two atrioventricular valves with no intervening septal echo [6, 13]. When scanning inferiorly toward the body of the ventricles, a distinct septal echo at the level of the midportion of the tricuspid valve can be ...
Nakano S - - 1984
A simple and effective adjunct to annuloplasty is presented for use in patients in whom dilatation of the annulus may not be sufficient to convert the tricuspid valve into a bicuspid valve. Several interrupted sutures are placed on the leaflets adjacent to the commissural zone between the anterior and posterior ...
Baughman K L - - 1984
The long-term survival rate of 74 consecutive patients who underwent multiple cardiac valve surgery including tricuspid valve surgery was analyzed to identify predictive preoperative clinical variables. Univariate analysis revealed that male sex (P less than 0.04), symptoms of New York Heart Association functional class IV heart failure (p less than ...

In 23 patients with Ebstein's anomaly of the tricuspid valve, the functional class of the patients has been related to the echocardiographic parameters generally used to diagnose this disorder. These are the extent of apical displacement of the tricuspid valve and the delay in tricuspid valve closure time related to ...
Mattleman S - - 1984
An 84-year-old female who previously underwent repair of an atrial septal defect had evidence of increased reflectiveness of the posterior tricuspid anulus in the apical four-chamber view and the right ventricular two-chamber view. In addition, the inferior vena cava was dilated and during contrast echocardiography, contrast echoes appeared during systole ...
Miyamura H - - 1984
Duplication of the tricuspid valve is a rare congenital cardiac anomaly. We experienced one infant case with Ebstein anomaly, who died at seven months of age. At autopsy, the clinical diagnosis was confirmed, and also the patient was found to have double tricuspid valve orifices, each of which were accompanied ...
Daliento L - - 1984
Clinical, vectorcardiographic, and echocardiographic data from two siblings with atrial septal defects and dysplasia of the mitral and tricuspid valves are reported. Vectorcardiograms showed that both siblings had abnormal ventricular activation with initial electrical forces directed posteriorly. One sibling died after surgery, and necropsy showed incomplete differentiation of the leaflets ...
Davies M K - - 1984
In a patient with severe tricuspid regurgitation and mild pulmonary stenosis due to carcinoid heart disease cross sectional echocardiography showed nodular thickening and coaptation of the tricuspid leaflets at the beginning of systole. The leaflets were, however, seen to be increasingly pulled apart as right ventricular systole proceeded. This finding, ...
Veyrat C - - 1984
It is now possible with pulsed Doppler to grade the severity of aortic, mitral and tricuspid regurgitations on a quantitative basis. "Indices" were devised, using the measurement of the spatial extent of abnormal Doppler signals. For aortic regurgitation: (1) at the aortic valvular orifice area, by measurement of the regurgitant ...

The angiographic and intraoperative findings are described in two children with imperforate tricuspid valve with atrioventricular and ventriculoarterial concordance who underwent a successful Fontan operation. It is important from a surgical point of view to distinguish this rare variant of tricuspid atresia from the more classic form with absent atrioventricular ...
Ilbawi M N - - 1984
Subpulmonary stenosis in transposition of the great arteries, resulting from a tricuspid valve pouch bulging into the left ventricular outflow tract through a ventricular septal defect, can be missed at the time of operation in the flaccid, nonbeating heart unless preoperative diagnosis has been established. In our experience, six patients ...
Willis P W PW - - 1983
Preoperative echophonocardiographic study of a 31 year old woman with Ebstein's anomaly and an atrial septal defect showed wide splitting of the first heart sound with an interval of 0.08 second between mitral valve and tricuspid valve closure. After application of the anterior tricuspid leaflet and anuloplasty, the mitral and ...
Dey H M - - 1983
A case is presented in which a portable nuclear scintillation probe was used to detect tricuspid regurgitation. An electrocardiographically-gated scintigraphic collection obtained over the liver was correlated with findings from contrast echocardiography and jugular venous pulse tracings. The nuclear probe may provide a simple means for the detection of tricuspid ...

We are presenting a case of endocarditis due to a penicillin-tolerant Streptococcus bovis in a 65-year-old patient. The minimal bactericidal concentration of penicillin (40 mg/l) was more than 100-fold the minimal inhibitory concentration (0.08 mg/l). The MBC of penicillin was 0.31 mg/l in the presence of 1.25 mg/l gentamicin. Cross-sectional ...
Tei C - - 1983
The tricuspid valve was examined by 2-dimensional (2-D) echocardiography in 14 patients with tricuspid valve prolapse (TVP) and in 16 normal subjects. Individual leaflets were identified anatomically and for frequency of prolapse. Maximal and minimal anular sizes were measured. Multiple tomograms of the tricuspid anulus were recorded at 30 degrees ...
Sharf M - - 1983
Ebstein's anomaly with pulmonary atresia was diagnosed in utero for the first time by fetal echocardiography. The fetus, examined at 35 weeks' gestation, had no extracardiac sonographic evidence of heart failure, but the heart filled the anterior portion of the chest. Two-dimensional echocardiography revealed a huge right atrium. The tricuspid ...
Mathews J L - - 1983
A 48-year-old woman with known Ebstein's anomaly had bilateral, lower-extremity arterial emboli after a total abdominal hysterectomy. She underwent embolectomy, placement of a Greenfield caval filter, subsequent tricuspid valve replacement, and closure of an atrial septal defect. Antemortem diagnosis of a paradoxical embolus is rare. To our knowledge, this is ...
Sheikhzadeh A - - 1983
The diastolic rumbling murmur of mitral stenosis (MS) may be attenuated in the presence of low cardiac output, right ventricular enlargement, Lutembacher's syndrome, pulmonary emphysema, and obesity. In this report we would like to stress that the presence of tricuspid stenosis (TS) is an additional significant cause of silent MS. ...
Lutas E M - - 1983
Two-dimensional echocardiographic evaluation of a young man with recent drainage of a hemorrhagic pericardial effusion revealed persistent fluid and a massive tumor involving the right atrium, tricuspid valve, and right ventricle. Echocardiographic demonstration of right atrial wall rupture was confirmed at surgery; pathologic analysis showed a spindle cell sarcoma.
Joyce L D - - 1983
A 16-month-old child was born with pulmonic stenosis and a hypoplastic right ventricle. After palliative procedures, the patient began having signs of tricuspid insufficiency and stenosis necessitating a tricuspid valve replacement. A St. Jude Medical valve was implanted. While the child was on aspirin therapy, thrombus formation resulted in valve ...
Taber M - - 1983
Carcinoid syndrome was diagnosed in a 48-year-old man by urinary 5-hydroxyindoleacetic acid test results and liver biopsy findings. Cardiac catheterization disclosed tricuspid stenosis and mild pulmonic stenosis.
