(1/34) Cor triatriatum in adults: three new cases and a brief review.

We report 3 cases of cor triatriatum that were diagnosed late, in the 4th and 5th decades of life. The presentations of these 2 men and 1 woman varied substantially, both in anatomic and symptomatic aspects. The woman had an associated complex congenital anomaly, which is not uncommon in cases of cor triatriatum. We present our cases, along with a review of this rare congenital cardiac anomaly.  (+info)

(2/34) Cor triatriatum sinistrum and persistent left superior vena cava: an original association.

Cor triatriatum sinistrum is a rare congenital heart disease usually diagnosed in symptomatic children. Symptoms depend on the degree of obstruction to pulmonary venous return with pulmonary hypertension and other associated abnormalities. Persistent left superior vena cava is quite a common congenital heart disease (about 0.5% in healthy populations). It should be suspected every time a dilated coronary sinus is detected at the echo examination. Transthoracic and transoesophageal examinations visualize the site and the size of the fibrous membrane as well as the degree of obstruction, and allow the evaluation of pulmonary pressures that are very important clues for prognosis and therapy. This case report describes the clinical signs and the diagnostic ultrasound findings evaluated in comparison with magnetic resonance imaging, a well-defined gold standard in heart disease of this uncommon congenital association.  (+info)

(3/34) Cor triatriatum sinister presenting in the adult as mitral stenosis.

Cor triatriatum sinister is a rare congenital defect in which the left atrium is divided by a fibromuscular membrane into two distinct chambers. Classically, patients present in infancy although in some cases they remain asymptomatic until adulthood. The clinical features on presentation can mimic those of mitral stenosis due to the obstructive properties of the membrane. Cor triatriatum sinister presented in this case in an adult as mitral stenosis. Factors that may be relevant in determining late presentation are also discussed.  (+info)

(4/34) A characteristic continuous wave Doppler signal in cor triatriatum?

Continuous wave Doppler recordings of the turbulent jet through the restrictive orifice of a left atrial partition in a patient with corrected transposition of the great arteries and cor triatriatum showed alternate bands of high intensity diastolic and low intensity systolic signals with preservation of the normal configuration of the diastolic E and A peaks. It is thought that Doppler studies in cor triatriatum will provide useful complementary haemodynamic information in the echocardiographic diagnosis of this anomaly.  (+info)

(5/34) Cor triatriatum sinister, not mitral stenosis, in an adult with previous Sydenham's chorea: diagnosis and preoperative assessment by cross sectional echocardiography.

In cor triatriatum sinister, one of the rarest congenital cardiac anomalies, a membrane divides the left atrium into a pulmonary venous component above and the vestibule below. The importance of the anomaly lies in the effects of the resultant pulmonary venous obstruction that usually present in the first year of life and can mimic obstructed total anomalous venous drainage or congenital mitral stenosis. A case presented as mitral stenosis in the third decade of life, ten years after a well documented episode of Sydenham's chorea. The diagnosis was made rapidly by transthoracic echocardiography and transoesophageal echocardiography was used for complete assessment. Cardiac catheterisation added nothing to the non-invasive diagnosis or the preoperative assessment. Uncomplicated corrective surgery was undertaken.  (+info)

(6/34) Ebstein's malformation with atrial septal defect, right cor triatriatum, and right overt accessory atrioventricular pathway.

A 31 year old man was admitted to hospital for abrupt syncope. Two dimensional echocardiogram in the apical four chamber view showed Ebstein's malformation. This is the first documented case of Ebstein's malformation with atrial septal defect, right cor triatriatum, and a right overt accessory atrioventricular pathway.  (+info)

(7/34) Inferior sinus venosus defect associated with incomplete cor triatriatum dexter and patent foramen ovale.

Sinus venosus atrial septal defect (SVD) is a rare cardiac abnormality in adults. Particularly, the inferior type is difficult to depict by transthoracic echocardiography because of its infero-posterior location to the fossa ovalis. We describe the case of a 33-year-old woman whose chest X-ray taken during bronchopneumonia revealed a cardiomegaly. Further echocardiographic investigations showed an underlying inferior SVD, an incomplete cor triatriatum dexter and a large patent foramen ovale (PFO). The diagnosis was confirmed by cardiac magnetic resonance imaging (CMR) and during surgical repair.  (+info)

(8/34) Spontaneous echo contrast of unexpected etiology.

Cor triatriatum sinister is a rare congenital anomaly characterized by the presence of a fibromuscular membrane dividing the left atrium into two chambers: one entering the four pulmonary veins, the other connecting to the mitral valve. The extent of the communication between the two chambers and the presence of associated lesions determine the severity of symptoms and the complications. We report the case of a 20-year-old man firstly diagnosed with obstructive cor triatriatum sinister and severe pulmonary hypertension.  (+info)
