The role of valve replacement in the treatment of Ebstein's anomaly of the tricuspid valve remains controversial. Since 1965, eight patients with Ebstein's anomaly ranging in age from seven to 22 years of age (mean 13 years) have undergone tricuspid valve replacement (TVR) in our institution. Seven were in functional ...
Linday L A - - 1983
Congenital cardiovascular anomalies associated with right-left atrial or ductal shunts must be excluded before a diagnosis of persistent fetal circulation (PFC) can be made. Despite the advent of 2-dimensional echocardiography (2-D echo), this differentiation can be difficult and may require cardiac catheterization with selective angiography. Fifteen consecutive cases were analyzed ...
Anderson R H - - 1983
Seven hearts were studied that had in common the segmental combination of double-inlet left ventricle, rudimetary right ventricle and ventriculoarterial concordance. The prototype of these hearts has been described as the "Holmes heart" or "single ventricle type A1." Five of the hearts had 2 atrio-ventricular valves; in 1 of these ...

In patients who have undergone prosthetic tricuspid valve replacement or tricuspid annuloplasty and in whom the pericardial space is obliterated by adhesions from previous operations, the need for ventricular pacing may be met by lead placement in the venous tributaries of the coronary veins. This approach avoids compromise of prosthetic ...
Mickell J J - - 1983
Thirty-five hearts were studied with no patent communication between the left atrium and the ventricular mass ('mitral atresia'). In ten, an imperforate and hypoplastic membrane separated the left atrium from a hypoplastic left ventricle. The imperforate valve ranged from a tiny membrane with no evidence of tension apparatus, through a ...

We reviewed the records of the Mayo Clinic patients with known carcinoid syndrome in whom echocardiographic studies had been done. Nineteen patients had M-mode and 2-dimensional echocardiographic examinations, and 1 patient had an M-mode examination only. Of the 20 patients, 8 had no evidence by echocardiogram of carcinoid heart disease; ...
Brugger J J - - 1982
Between 1976 and 1979, 76 patients underwent tricuspid annuloplasty (TA) for predominant tricuspid regurgitation (TR). The TR was functional (secondary to mitral valve disease) in 70, postrheumatic in 4, posttraumatic in one and secondary to myxomatous degeneration in one. The mean preoperative functional class was 3.05 and cardiac index 2.15 ...
Donaldson R M - - 1982
Abnormal tricuspid valve structure and motion resulting from the rupture of a right ventricular papillary muscle were visualised by two dimensional echocardiography. These findings were confirmed at operation. Two dimensional echocardiography appears to be a satisfactory method for evaluating patients with tricuspid regurgitation of sudden onset with a view to ...

In the second patient suffering ...
Steding G - - 1981
A concept for the explanation of the formal genesis of congenital cardiac malformations is introduced, based on the observation that 1. the septa in the outflow-tract of the heart are formed in spatial relation to changes in form of the external cardiac wall and always along the longer sides of ...
Thiene G - - 1981
Several investigations have recently been published which suggest that classical tricuspid atresia is produced by an imperforate valve membrane interposed between the right atrium and the underlying hypoplastic right ventricle. Since this is contrary to our understanding of the anatomy of the majority of examples of tricuspid atresia, and since ...
Péterffy A - - 1981
Changes of the central haemodynamics at rest and during exercise were evaluated in 45 patients who underwent tricuspid valve surgery. Tricuspid valve disease was associated with left heart valvular lesions in 42 patients, while isolated tricuspid valve lesions were present in 3 patients. The pre-operative evaluation showed marked impairment of ...
Midwall J - - 1981
Present methods of assessing tricuspid regurgitation are often unreliable. We present preliminary data concerning a new angiographic method for identification of tricuspid regurgitation which evaluates direction of flow of contrast media during right ventricular (RV) systole in the inferior vena cava (IVC) and hepatic veins following right atrial or IVC ...
