Wenink A C - - 1981
The formation of the ventricular septum was studied in human embryos ranging from 3.6 to 25 mm CR-length. Before septation, two distinct chambers are present which will contribute to the adult ventricles. They are called the bulbus and the ventricle. The circular constriction between these chambers is the bulboventricular fold. ...

2 patients with Dandy-Walker malformations (DWM) and cardiac anomalies are presented. The types of cardiac defects with septal involvement are suggestive of an early embryonic abnormality occurring before 6 weeks' gestational age. This correlates with the postulated timing of the development of the DWM and suggests a complex developmental anomaly. ...

A 42 year old woman presented with impaired filling of the right atrium and right ventricle two years after removal of uterine leiomyomas. At the time of hysterectomy, intravenous leiomyomatosis was noted, with extension of the tumor into the inferior vena cava. The tumor subsequently extended into the right atrium ...
Baum V C - - 1980
Increased inspiratory right ventricular filling with a consequent shift of the ventricular septum to the left, thereby decreasing left ventricular filling, has been suggested as a mechanism of pulsus paradoxus. We recently saw a patient with tricuspid atresia and hypoplastic right ventricle who developed pulsus paradoxus. His course may help ...
Kratz John M. - - 1980
In an automobile accident, a young man sustained blunt trauma to the chest that caused injury to the fibrous skeleton of the heart. The mitral and tricuspid valves and their annuli were lacerated, the aortic annulus was separated from the ventricular septum, and the ventricular septum was disrupted; however, with ...

This article describes the determination of small systemic ventricular volume by quantitative cineangiocardiography in two patients with congenitally corrected transposition of great arteries, Ebstein's malformation of the systemic atrioventricular valve, and ventricular septal defect. A subjectively small systemic ventricle and an Ebstein-like abnormality of the systemic atrioventricular valve have been ...
Alam M - - 1980
M-mode echocardiographic features are presented in four patients with membranous ventricular septal defect. The most consistent echo findings in all the patients were the presence of fuzzy, fluttering echoes of the tricuspid valve during systole. More careful echocardiographic evaluation of the tricuspid valve in ventricular septal defect is therefore recommended.
Cachera J P - - 1980
The proposed procedure consists of interchanging the positions of the atria by means of an incision used in heart transplantation. After frontal sectioning of the atrial body, the heart is turned up on its pedicle, the interatrial septum is divided in its posterior part, and the vena cavae are extensively ...
Patel R G - - 1980
Right ventricular growth was assessed angiocardiographically in 18 patients with pulmonary atresia, intact ventricular septum, and hypoplastic and hypertensive right ventricle. A variety of surgical procedures were performed. In only 12 patients (66.7%) was right ventricular-pulmonary artery continuity achieved (group 1). Nine of these 12 patients persisted with systemic or ...
Boffa G M - - 1980
A case of transient tricuspid insufficiency in a newborn is reported. Cardiac catheterization performed at the age of two days because of cyanosis and cardiac failure, showed massive tricuspid incompetence, a normal tricuspid valve, increased diastolic volume of both ventricles valve, increased diastolic volume of both ventricles and depressed left ...
Daniel W - - 1980
M-mode echocardiographic studies were performed in 11 patients, most of them adults, with Ebstein's anomaly of the tricuspid valve, proven by cardiac catheterisation. Simultaneous recordings of the tricuspid and mitral valves were obtained in all cases, the transducer position being outside the left midclavicular line in seven patients. Tricuspid valve ...

The authors investigated 10 ambulant patients with myotonic dystrophy, under 40 years of age (mean 22.3 years) and free of subjective heart complaints. Not only Ecg alterations but also kinetocardiographic changes and anomalies of the systolic intervals were rarer and milder than those found in patients with other neuromyopathies, namely ...
Piccoli G P - - 1979
Anatomical studies were made on 70 necropsied hearts with atrioventricular defects from patients with situs solitus and atrioventricular concordance, all having a common atrioventricular orifice. The arterial connections were concordant in 68 and were double outlet right ventricle in two; cases with arterial discordance (transposition) or single outlet of the ...
Piccoli G P - - 1979
Anatomical studies were made on 114 necropsy specimens of atrioventricular defects with atrioventricular concordance. The malformation is characterised by disproportion between the ventricular inlet and outlet dimensions and a malorientation of the aortic valve relative to the atrioventricular valve or valves. Associated with this there is a characteristic 'scopped-out' appearance ...
Inoue D - - 1979
A patient with click and late systolic murmur syndrome originating in the right side of the heart is described. Prolapse of the anterior tricuspid leaflet was demonstrated by subxiphoid two-dimensional echocardiography alone. Neither of the mitral leaflets showed any evidence of prolapse on the echocardiogram. The prolapsed anterior tricuspid leaflet ...
Soto B - - 1979
An angiographic analysis of 10 cases of univentricular heart of the right ventricular type is reported. This congenital malformation is characterized by a large chamber with right ventricular morphology that receives both atrioventricular valves, and a second, smaller chamber, a trabecular pouch, with left ventricular morphology. These chambers are separated ...
Come P C - - 1979
Atrial myxoma has been diagnosed on the basis of a characteristic M mode echocardiographic pattern of a mass of echoes appearing, with a lag phase, beneath the anterior leaflet of the mitral or tricuspid valve in diastole. However, this pattern is not specific for an atrial tumor. Two patients are ...
Calcaterra G - - 1979
Dextrocardia can be defined as a heart in the right chest with the major axis to the right. This definition, however, conveys no information regarding the chamber arrangements and internal anatomy of the heart. Of 40 patients satisfying this definition in the files of the Brompton Hospital, 33 had angiocardiographic ...
Chandraratna P A - - 1979
This report describes a spectrum of M-mode and cross-sectional echocardiographic abnormalities in eight patients with infective endocarditis of the tricuspid valve. The M-mode echocardiogram of the tricuspid valve was abnormal in all but one patient in whom abnormal echoes were seen anterior to the tricuspid valve, in the right ventricular ...
Doty D B - - 1979
The technique of septation of the univentricular heart via a transatrial approach is described in detail. Clinical details of four patients having Type A-III univentricular heart document the feasibility of working through the right-sided atrioventricular valve to place a cloth prosthesis into the ventricle to divide it into approximately equal ...
Freedom R M - - 1979
We have presented the unique clinical and morphological features of 3 patients with an imperforate tricuspid valve and right ventricular tensor apparatus. Thus, despite valve tissue and apparatus, there was not a perforate atrioventricular connection. This most uncommon type of tricuspid atresia' was associated in all 3 cases with a ...

An 18-year old white youth presented with severe right heart failure and was found to have an obliterated and funnel-shaped right ventricle, massive tricuspid regurgitation, and mitral regurgitation. The haemodynamic findings were those of cardiomyopathy with obliteration on the right side. He underwent surgery consisting of decortication and peeling off ...
Bove E L - - 1979
The role of valve replacement in the treatment of Ebstein's anomaly of the tricuspid valve remains controversial. Between 1965 and 1977, five patients with Ebstein's anomaly ranging in age from 11 to 57 years (mean 29) underwent tricuspid valve replacement in our institution. All of the patients were cyanotic but ...
Dickinson D F - - 1979
Three hearts are described in which a fibrous membrane was interposed between the right atrium and a formed but hypoplastic right ventricle, which possessed recognisable inlet, trabecular, and infundibular components. In these hearts the distribution of the conducting tissue was as expected for concordant atrioventricular connections, and contrasts with that ...
Marino P - - 1979
2 patients, aged 8 mth and 48 yr, referred for a clinical diagnosis of ventricular septal defect, were studied by ultrasound. In both a fluttering and an anterior bowing of the systolic segment of the tricuspid valve was found, consistent with a left ventricular--right atrial communication. Diagnosis was confirmed by ...
Tynan M J - - 1979
At present there is no universally accepted nomenclature for congenital cardiac malformations. Much of the controversy results from failure to distinguish the structural connections of the heart from the morphology and spatial relations of its components. The confusion is compounded by an abundance of individual definitions, many of them speculative. ...
Anderson R H - - 1979
The ventricle morphology is described in hearts in which the entire atrial inputs are committed to a single chamber in the ventricular mass, this being considered the criterion for definition of the univentricular heart. Such a definition does not exclude from the univentricular category hearts with two chambers in their ...
Villani M - - 1979
Twenty patients with atrio-ventricular canal malformations (5 complete and 15 partial forms) were operated upon during the last two years, using new surgical techniques. The repair of the complete form based on a three-leaflet three-commissure mitral valve concept, was accomplished by: a) Two separate partitioning patches (one ventricular, one atrial), ...
Quero-Jiménez M - - 1979
Anomalies of the atrio-ventricular valves are frequent in cases of univentricular heart with severe symptomatology during the first year of life and in necropsy material. This suggests that they are important determinants of the natural history of the malformation. Radical "corrective" surgery, in the presence of these anomalies, may be ...
Wilkinson J L - - 1979
A simple system for the analysis and classification of the univentricular heart is described. The basis of this approach is the use of a step by step sequential nomenclature with attention paid to the morphology, connexions and relationships of each cardiac segment in turn. Three major morphological types of univentricular ...
Zuberbuhler J R - - 1979
The morphological features of a series of 37 specimens of pulmonary atresia with intact ventricular septum were reviewed with particular emphasis on features which might influence the results of pulmonary valvotomy. The degree of right heart hypoplasia was quantified by measuring right and left heart dimensions and comparing them with ...
Keeton B R - - 1979
The coronary arterial anatomy in 26 univentricular hearts, its relation to the morphologic characteristics of the ventricles and rudimentary chambers, and its surgical implications were analyzed. All of the hearts except two had been operated on; 18 had septation with or without an extracardiac conduit and 6 had had palliative ...
Seward J B - - 1979
This is a report of the longest survival of a patient with Ebstein's anomaly. The patient had no cardiac symptoms until the age of 79 years, when he presented with severe tricuspid incompetence and congestive heart failure, from which he ultimately died. The diagnosis was established by utilizing two-dimensional sector ...
Anderson K R - - 1979
Ebstein's anomaly of the tricuspid valve is associated with right ventricular dilatation in approximately two-thirds of cases. Dilatation may be massive. It involves not only the right ventricular wall proximal to the tricuspid valve (atrialized ventricle) but also the right ventricle distal to the valve (funtional right ventricle), including the ...
Sheikh M U - - 1979
Systolic honks have so far been synonymous with prolapse of the mitral valve leaflet. Evidence of tricuspid valve involvement in two cases is presented. These patients developed systolic honk during the deterioration of their congestive heart failure. Simultaneous recordings of echocardiograms and phonocardiograms showed fluttering of the tricuspid valve, coinciding ...
Sheikh M U - - 1979
Echocardiographic observations are described in 10 patients with right-sided bacterial endocarditis. Six of the nine patients with tricuspid regurgitation had shaggy echoes on the tricuspid valve, which were confirmed to be vegetations on autopsy in two patients. In six patients, right ventricular dilatation was present, and paradoxic septal motion was ...
Keeton B R - - 1979
Seventeen cases are described in which both atria connect directly to a chamber with right ventricular characteristics. The atria connected through separate atrioventricular valves in six hearts and a common valve in 11. All hearts had a posterior rudimentary chamber. The septum which separated it from the main chamber was ...
Henry J G - - 1979
A case is reported concerning echocardiographic findings in a patient with congenital corrected transposition of the great vessels and Ebstein's anomaly of the tricuspid valve. This presented an unusual opportunity to study atrioventricular valve closure in a patient in whom the Ebstein's malformation involved the systemic atrioventricular valve. The mitral ...
Ng R - - 1979
Between 1969 and 1976, 10 severely disabled patients with Ebstein's anomaly were operated on at the National Heart Hospital using replacement of the tricuspid valve with mounted aortic homografts [9] or dura mater valve [1], plication of the atrialized right ventricle [10], and closure of an associated interatrail communication. 7 ...
Serruys P W - - 1979
Bidimensional contrast echocardiological examinations were carried out in 120 patients with the use of dynamically focussed multiscan. Ultrasonic contrast was produced by a push injection of 10 ml of isotonic saline or of 5% glucose in water injected into an antecubital vein through an 18 gauge needle. Contrast studies were ...
Freedom R M - - 1978
The angiocardiographic features of 11 patients with superoinferior and criss-cross type of atrioventricular (A-V) connections are presented. These unusual ventricular relations are thought to result from postseptation disturbances of ventricular looping. The angiocardiographic appearance of criss-cross is really an illusion, and the A-V connections among these patients are either concordant, ...
Bowman F O FO - - 1978
A modification of Fontan's approach to the surgical management of tricuspid atresia was employed in nine patients. A valved conduit was used to create continuity between the right atrium and the surgically modified right ventricular chamber. Six patients had had previous shunting procedures. Preoperative studies revealed various degrees of hypoplasia ...
