Cor triatriatum with repeated episodes of syncope in an eighteen month-old girl: a rare cause of cardiogenic syncope.
(9/34)Syncope can be caused by either cardiogenic or noncardiogenic causes. Structural heart diseases should be considered as a possible cause of recurrent episodes of syncope if no other causes are found. We report an 18 month-old girl who presented with recurrent syncope as well as dyspnea, failure to thrive, and frequent episodes of pulmonary infections, suggesting congestive heart failure. A prominent pulmonic component of the second heart sound and congested lungs noted from chest X-rays indicated pulmonary hypertension. An echocardiogram revealed an abnormal membrane with a small orifice in the left atrium (LA). An intact atrial septum and no evidence of other congenital heart diseases were observed. The result after surgical resection of the membrane was good during follow-up. Cor triatriatum may be one of the structural heart diseases responsible for repeated unexplained syncope. An echocardiogram performed by an experienced cardiologist would facilitate the diagnosis considerably and an excellent prognosis can be achieved via surgical resection of the obstructing membrane.

Anomalous dual drainage of the right pulmonary veins in a patient with cor triatriatum: report of a case without scimitar sign.
(10/34)The majority of patients with partial anomalous drainage of pulmonary veins are asymptomatic during infancy and childhood. Patients with significant left-to-right shunt develop symptoms and benefit from early corrective surgery. Anomalous pulmonary veins draining into inferior vena cava is very rare and frequently encountered in association with scimitar syndrome. The purpose of this case report is to describe a non-scimitar patient with cor triatriatum who had anomalous dual drainage of right pulmonary veins into inferior vena cava/left atrium and anomalous connection of persistent left superior vena cava with a common pulmonary venous chamber. The patient underwent an operation with redirection of anomalous pulmonary venous drainage into left atrium and ligation of persistent left superior vena cava. (+info)
Right atrial and tricuspid hypoplasia.
(11/34)Cor triatriatum dexter is a rare cardiac anomaly with division between the sinus and primitive atrial portions of the right atrium. It is supposed that the failure of the venous valves to regress appropriately may create abnormalities in fetal circulation predisposing the fetus to maldevelopment of the right heart structures. The underdevelopment of the right ventricle with hypoplasia or atresia of the tricuspid valve is a well known abnormality, but underdevelopment of the right atrium with tricuspid hypoplasia due to multiple venous valves is extremely rare. This is a case of complex type of cor triatriatum dexter in which the right atrium is hypoplastic and like a tube formed by the superior and inferior vena cava and is divided into 3 portions by 2 membranes.

Cor triatriatum: the utility of cardiovascular imaging.
(12/34)A 44-year-old man with no known cardiac history presented with worsening dyspnea on minimal exertion. During follow-up, computed tomography angiography and echocardiography confirmed the incidental finding of cor triatriatum. As improvements in spatial and temporal resolution continue, cardiac computed tomography may become better suited to the dynamic imaging of anatomical defects in the heart, including, but not limited to, coronary artery disease.

"Asthma": an unusual presentation of cor triatriatum.
(13/34)We discuss an extremely unusual presentation of a 19-month-old child with cor triatriatum and an intact interatrial septum, who presented for the first time at the age of 16 months with wheezing and repeated lower respiratory tract infections. At surgery, a thick fibromuscular membrane with a 2-3 mm eccentrically placed orifice was identified, and following surgical resection of the membrane the child made an uneventful recovery. This case demonstrates the need for investigating children with "asthma" who do not respond to conventional medical management. A rare but potentially correctable underlying cause may be found.

Clinical follow-up of a pregnant woman with cor triatriatum.
(14/34)Cor triatriatum (CT) is a rare congenital cardiac anomaly that usually becomes symptomatic in the first years of life. If the condition is not associated with other cardiac defects, and depending on the degree of communication between the upper chamber and left atrium (LA), patients may reach adulthood. We report a case of an asymptomatic, adult, female patient with CT diagnosed by transthoracic echocardiogram (TTE) and followed-up during pregnancy. (+info)
A rare variant of Ellis van Creveld syndrome.
(15/34)A nine-year-old boy presented with progressively-increasing exertional dyspnoea for the last three months. The only significant finding in the general survey was polydactyly. His vital signs were normal. He had a prominent apical diastolic thrill, a prominent S1 with a low-pitched grade 4/6 mid diastolic rumbling murmur over the apex. The S2 was widely split, fixed and the second component was louder than the first one. There was a grade 3/6 ejection systolic murmur over the left second intercostal space. Electrocardiography showed features of left axis deviation, bi-atrial enlargement and right ventricular hypertrophy. Transthoracic echocardiography identified a thin undulating intra-atrial membrane on the left side along with an ostium-primum defect. In this patient, the diagnosis of a variant of Ellis van Creveld syndrome was made. (+info)
Three-dimensional transthoracic echocardiographic evaluation of cor triatriatum.
(16/34)We present an adult patient with cor triatriatum (CTT) due to a left atrial (LA) membrane. Two-dimensional and real-time three-dimensional transthoracic echocardiography (3DE) were performed as well as echocardiographic examination after exercise. These non-invasive modalities provided a comprehensive anatomic and hemodynamic evaluation of the anomaly. (+info)
