Schmidt M C - - 1996
BACKGROUND: Coronary anomalies in the absence of other major cardiac malformations are rare, with an incidence of less than 1-1.5%. Although most have been incidental findings without clinical relevance, a subgroup of anomalies has been identified that are associated with cardiac symptoms or even sudden cardiac death. This subgroup includes ...

A patient with cardiac cirrhosis due to severe tricuspid regurgitation associated with a mitral valve lesion successfully underwent mitral and tricuspid valve replacement. Preoperative rest cure with liver supporting therapy for 5 months was used to maximize hepatic and cardiac function. Postoperatively, jaundice developed despite improvements in cardiac function. Plasma ...
Fujiwara T - - 1996
A case of traumatic rupture of the tricuspid chordae tendineae with severe regurgitation in a patient who previously had mitral valve replacement is presented. In this case, it is strongly suggested that a firm pericardial adhesion of the anterior right ventricular wall became a factor of the disruption of the ...
Bapat V N - - 1996
A male child presented with suspicion of tricuspid stenosis. Echocardiography revealed the presence of a mass arising from the free wall of the right ventricle and causing right-ventricular inflow obstruction but not involving the tricuspid valve. The tumour was excised via right ventriculotomy using cardiopulmonary bypass, resulting in survival and ...
Sutter A - - 1996
Myocardial dysplasia involves a quasi-complete or localized absence of myocardial fibers in the right or left ventricle, with corresponding partial or complete filling by fibroadipose tissue. This disorder, in its full form called "Uhl's anomaly", was first described in 1952 as an anomaly of the heart conferring a parchment-like appearance ...
Boxt L M - - 1996
Patients with congenital heart disease often require mild sedation for the performance of their examination. If adequate monitoring of systemic oxygen saturation and heart rate is performed, then these patients may be adequately studied by MR imaging. Cardiac examination using spin echo pulse sequences provides morphologic information that allows evaluation ...

BACKGROUND: Between 1982 and 1984, we successfully performed "one and a half ventricular repair" using a Glenn shunt for 3 patients with pulmonary atresia with intact ventricular septum. Here we review the 10-year follow-up results. METHODS: In these patients, the preoperative Z scores of the tricuspid valve diameters ranged from ...
Kalangos A - - 1995
We report 2 patients who presented extensive rupture of chordae tendineae caused by blunt thoracic trauma leading to flail anterior leaflet of tricuspid valve. Transposing a segment of septal leaflet in 1 patient and the posterior leaflet in the other patient onto the flail anterior leaflet's margin abolished massive tricuspid ...
De Simone R - - 1995
BACKGROUND: The etiology of tricuspid and mitral valve regurgitation (TR and MR) after heart transplantation is still controversial. METHODS: We studied 25 patients undergoing transplantation and intraoperative transesophageal echocardiography to evaluate the incidence, the degree, and the cause of TR and MR. The degree of valve regurgitation was assessed by ...
Kreitmann B - - 1995
In December 1992, cardiac transplantation (for right heart failure with partially occluded pulmonary arteries but with a normal left ventricle) was accomplished with partial resection of right atrium and ventricle but with preservation of the left heart, obtaining a three-ventricle heart. The short-term result (27 months) is good, with normal ...
Barlow A - - 1995
BACKGROUND: Controversies in nomenclature, especially of hearts with "single ventricle," have clouded discussion and understanding of the anatomy. Many patients with such malformations are submitted to the Fontan procedure as definitive surgical palliation. The spectrum of anatomy among these patients is wide and deserves analysis in an effort to provide ...
Fujimoto S - - 1995
PURPOSE: To assess right ventricular filling in dilated cardiomyopathy. PATIENTS: 32 patients with dilated cardiomyopathy and 24 healthy controls. METHODS: Stroke distances were measured by pulsed Doppler echocardiography at left ventricular outflow and left and right ventricular inflow. The inflow tract dimensions of both ventricles and the outflow tract dimension ...
Bouman H G - - 1995
BACKGROUND: In a recently developed chick model the teratogen retinoic acid has appeared to induce a spectrum of double outlet right ventricle, which needs further detailed evaluation. It is known that retinoic acid is able to induce cardiac malformations. Although the exact mechanism is not known, an interaction with neural ...
Orie J D - - 1995
OBJECTIVES: Our aim was to clarify the anatomic substrate in hearts diagnosed as having tricuspid atresia by studying autopsy specimens and comparing the findings with those in two-dimensional echocardiograms. BACKGROUND: Traditionally, tricuspid atresia was thought, and is still believed by some, to be due to an imperforate valvular membrane interposed ...
Danielson G K - - 1995
The development of the extracardiac conduit has been one of the greatest advances in cardiac surgery. Conduits have decreased the mortality rate of several standard operations and have made possible the correction of numerous complex congenital cardiac anomalies that previously were uncorrectable. However, the ideal conduit has not yet been ...
Prenger K B - - 1995
Three patients are described with the combination of a luxation of the heart through a pericardial tear and traumatic rupture of the papillary muscle of the tricuspid valve. In only 1 patient was the dislocation of the heart suspected preoperatively. In all 3 patients operative treatment was performed with considerable ...
Koponen M A - - 1995
We describe unusual left ventricular cardiac lesions in a 17 year old boy who died suddenly during exertion. These consisted of two grossly evident regions of deficient myocardium, containing cavernous spaces which represented exaggerated intertrabecular regions of the left ventricular cavity. Dense fibro-elastotic tissue was deposited around these spaces along ...
Janzing H M - - 1995
A patient with a severe liver injury and an acute cardiac failure due to a traumatic tricuspid valve failure is presented. During liver surgery, massive venous bleeding was caused by regurgitation of blood through the insufficient tricuspid valve. Right ventricular failure, leading to persistent hemodynamic instability, and caused by massive ...
Voci P - - 1995
Persistent left superior vena cava occurs in 2-4% of all congenital cardiac defects. The diagnosis is often missed if the lesion is not accurately looked for. Drainage to the coronary sinus is well tolerated, whereas drainage to the left atrium produces right to left shunt and may be associated with ...
Smith R S - - 1995
OBJECTIVE: To determine if a relation exists between left cardiac axis deviation and fetal anomalies. METHODS: Estimation of cardiac axis was attempted prospectively as part of the cardiac examination in approximately 41,500 second- and third-trimester fetuses scanned between 1987-1993. Those with heart axes greater than 75 degrees to the left ...
Kumar N - - 1995
Tricuspid valve pathology in Ebstein's malformation requires replacement when it is not possible to repair or reconstruct this valve. In smaller children, in whom the right-sided atrioventricular valve is severely dysplastic and right ventricular volume is prohibitive, prosthetic replacement is not always possible. We report here on 3 patients who ...
Lamers W H - - 1995
BACKGROUND: Some of the problems concerning the origin of the inlet component of the definitive right ventricle were resolved in a previous study in which we showed it to be derived exclusively from the embryonic right ventricle. Questions remain, however, concerning the relative contributions of endocardial cushion tissue and myocardium ...
Hecher K - - 1994
This report describes the sequence of events in the development and subsequent spontaneous resolution of functional tricuspid valve atresia in the donor fetus in a case of twin to twin transfusion syndrome. Fetoscopic laser coagulation of the placental anastomoses was performed at 20 weeks' gestation. Subsequently, there was evidence of ...
Ras F - - 1994
Studies on facial left-right dominance in individuals without craniofacial anomalies have demonstrated controversial results. This is probably due to the frequent use of two-dimensional methods, yet left-right dominance consists of transverse, vertical, and sagittal components. The aim of the present study was to describe three-dimensionally facial left-right dominance in individuals ...
Respondek M L - - 1994
OBJECTIVE: Our purpose was to assess the prevalence, cause, and clinical significance of fetal tricuspid valve regurgitation in structurally normal hearts during indicated fetal echocardiographic examination. STUDY DESIGN: The prevalence of fetal tricuspid regurgitation was retrospectively evaluated in a group of 733 singleton fetuses referred for routine fetal echocardiography. RESULTS: ...
Lin S S - - 1994
BACKGROUND: Right ventricular volume overload (RVVO) occurring in conditions such as Ebstein's anomaly may result in depression of left ventricular ejection fraction (LVEF). This study tests this hypothesis by measuring LVEF in 10 patients with RVVO due to tricuspid valve resection for isolated tricuspid valve endocarditis and in 10 age-matched ...
Wu Y L - - 1994
A full-term baby girl was diagnosed at birth using echocardiography to have a single ventricle with common atrioventricular valve and subaortic ridge. On the 22nd day after birth she was admitted to hospital for intensive care after sudden onset of cyanosis. Three days later she died after repeated attacks of ...
Iga K - - 1994
We retrospectively examined 8 patients who had classical physical signs of tricuspid regurgitation associated with congestive heart failure, the cause of which was not identified by echocardiography. Exclusion criteria were as follows; 1) peak velocity of tricuspid regurgitation greater than 3 m/sec, 2) disturbance of left ventricular wall motion, 3) ...
Rinaldi R G - - 1994
Right coronary arteries that arise from the left sinus or ectopically from the right sinus with a slit ostium can cause myocardial ischemia, myocardial infarction, or sudden death. The surgical repair of these anomalies has evolved toward a simpler operation that widens the orifice of origin and reduces the compression ...
