Cor Triatriatum Sinister

A seven-month-old, male domestic shorthair was presented for respiratory distress. Cor triatriatum sinister was diagnosed based on echocardiography. Surgical dilatation and tearing of the anomalous membrane dividing the left atrium resulted in resolution of clinical signs. Intraoperative echocardiography was used to evaluate the adequacy of the repair.

Cor Triatriatum Sinister

A 3-year-old, 4-kg, castrated male domestic shorthair cat presented with signs of progressive respiratory distress. Thoracic radiographs showed pulmonary edema and pleural effusion. Echocardiography revealed a perforate membrane immediately above the mitral valve that divided the left atrium into proximal and distal chambers. The left auricle was proximal to the dividing membrane and connected to the markedly enlarged proximal left atrial chamber, consistent with the diagnosis of supravalvular mitral stenosis (SMS). Position of the obstructing membrane relative to the left auricle distinguishes SMS from cor triatriatum sinister (CTS). In CTS, the left auricle is distal to the dividing membrane and connects to the distal left atrial chamber.

SummaryCor triatriatum sinister is a rare congenital cardiac anomaly that has been identified in 0.1% of children with congenital heart disease. It is defined as a fibromuscular membrane that divides the left atrium into two chambers: a superior (proximal) that in most cases receives drainage from the pulmonary veins and an inferior (distal) chamber that communicates with the mitral valve and the left atrium. Cor triatriatum sinister can be an isolated lesion (approximately 25% of cases), but in many cases it is associated with other congenital cardiovascular anomalies, the most common one being – atrial septal defect(3). Symptoms in patients with cor triatriatum sinister are related to obstruction of pulmonary venous drainage, pressure loading of the right side of the heart and congestive cardiac failure. Depending on the severity of the obstruction and presence of associated cardiac anomalies it can be diagnosed at any age. Diagnosis is usually achieved by echocardiography in early infancy. Elective treatment method is surgical excision of the membrane. Here we present a pediatric patient (4 months old) presenting in cardiogenic shock with a successful correction of isolated cor triatriatum sinister. To confirm diagnosis and success of surgical repair, transthoracic and transesophageal echocardiography were used.

Cor Triatriatum Sinister

We describe an infant with hypoplasia of the left heart diagnosed prenatally who, at birth, had signs of severe pulmonary venous obstruction. Echocardiography indicated normally connecting pulmonary veins, and showed a paradoxical right-to-left shunt across a patent oval foramen. Postmortem examination revealed that the obstruction was due to a divided left atrium, or cor triatriatum sinister, with an imperforate muscular diaphragm separating completely the two components of the divided atrium.

Echocardiographic Findings

A 3-year-old male French Bulldog was evaluated due to recent history of intolerance to exercise and coughing. The clinical, radiographic, and echocardiographic findings were consistent with cor triatriatum sinister (CTS), a congenital heart anomaly in which the left atrium is subdivided into two compartments by an abnormal fibromuscular membrane. This defect has been rarely recognized in humans and in domestic cats. To the best of our knowledge, this is the first report of the disorder in the canine species.

We describe a patient with concordant ventriculoarterial connections with parallel arterial trunks, divided left atrium (cor triatriatum sinister), ventricular septal defect, bilateral superior caval veins, and juxtaposed atrial appendages. The aorta was anterior and left sided. We discuss the morphological features of this rare condition, and the diagnostic dilemma it produced.

Cor Triatriatum Sinister

Abstract Background Cor triatriatum sinister (CTS) is a rare congenital cardiac anomaly defined by a fibromuscular membrane which bisects the left atrium. Cor triatriatum sinister has been associated with cardioembolic stroke through mechanisms including stagnation of blood flow within the left atrium, an association with atrial fibrillation (AF), and/or an accompanying atrial septal defect (ASD) or patent foramen ovale. We describe a case highlighting the role that CTS may play in cardioembolic stroke, provide high-quality computed tomography angiography and two- and three-dimensional echocardiography of the CTS membrane, and outline management strategies for this uncommon clinical scenario. Case summary A 35-year-old man with no prior medical history presented with acute onset weakness and aphasia. He was found to have an embolic stroke with left M1 and A1 occlusions and received tissue plasminogen activator followed by mechanical thrombectomy with successful recanalization. A thorough stroke workup revealed CTS with an associated ASD as well as potential protein C deficiency. He was managed with indefinite anticoagulation with apixaban. Discussion This is the 13th reported case of CTS associated with stroke. In most previous cases evidence of blood stasis or frank thrombus was associated with the CTS membrane, and/or existing AF was noted. In this case, none of these were identified, particularly highlighting the surreptitious risk of CTS. In addition, the presence of potential protein C deficiency in this case compounded the risk for thromboembolism and factored into multidisciplinary management decisions.

Rare Malformation

Obstructive total anomalous pulmonary venous return (TAPVR) is a potentially life-threatening clinical condition and a surgical emergency. Left-sided partial anomalous pulmonary venous return (PAPVR) in association with a subdivided left atrium, also known as cor triatriatum sinister (CTS), is a very rare malformation that can mimic obstructive TAPVR. We present a case of a newborn with clinical manifestation of cardiogenic shock caused by CTS and PAPVR.
