Cor triatriatum may exist as a stand alone abnormality [1], or may be associated with other congenital heart malformations, some caused by absent or abnormal conotruncal inversion, some by persistence of embryonic structures, some by lack of atrial, ventricular or atrioventricular septum development [2]. Some associations, such as between cor triatriatum and a bicuspid aortic valve, may be harder to explain as a consequence of a single event in embryonic development and may occur as separate entities [3]. Other left heart obstructive lesions may also exist [4].

The patient presents for various reasons, depending on heart anatomy and function. If the abnormality is left- sided, symptoms are similar to those induced by mitral stenosis, appear sooner and are more dramatic if the opening in the accessory membrane separating the true left atrium from the supranumerary chamber is smaller. If this communication is large, the patient may be asymptomatic and diagnosis is made on an echocardiography examination performed for other reasons. If complaints do exist, they consist of hemoptysis, orthopnea and signs of left heart failure: dyspnea on exercise and asthenia. Children with a restrictive membrane defect fail to thrive or may present with severe neonatal respiratory distress [5] due to the pressure gradient between the true and accessory atrial chambers. In cor triatriatum dexter, right heart failure signs appear first and consist of edema, ascites, painful hepatomegaly and jaundice. Rhythm abnormalities like atrial fibrillation or tachycardia may coexist in both forms. Physical examination of a cor triatriatum sinister patient may reveal further abnormalities: signs of systemic embolism, pulmonary rales or pleural effusion, heart murmurs, tachypnea and respiratory distress. In a right sided abnormality, the physician may find elevated jugular venous pressure, tricuspid regurgitation and right ventricular heave. Pulmonary hypertension may also be present. Adults become symptomatic if the membrane within the left atrium becomes calcified [6] or during sustained effort, such as labor [7] [8].

• Congestive Heart Failure

  We present here a 6-year old boy who was diagnosed with cor triatriatum sinister, initially showing symptoms similar to mitral valve stenosis and congestive heart failure, and who underwent subsequent surgical correction using a left atrial approach. [ncbi.nlm.nih.gov]

  Conclusion The natural history of CTS most often manifests with symptoms of congestive heart failure. Patients with obstructive membrane most often have associated cardiac defects and higher risk for infections and haemorrhage. [heart.bmj.com]

  It is imperative to address AF in these patients, irrespective of their CHA₂DS₂-VASc scores (congestive heart failure, hypertension, age, diabetes mellitus, stroke, vascular disease, age, sex category) due to their higher risks of thromboembolism. [cureus.com]

  Cor triatriatum, a term suggested by Borst,1 in 1905, is a rare congenital malformation of the heart in which the left atrium is divided into two chambers by a fibrous or membranous septum. [jamanetwork.com]

Hypoxemia may be noticed in a newborn with severe respiratory distress caused by cor triatriatum. The electrocardiogram may be normal or it may show signs of right ventricular hypertrophy and strain, right axis deviation, left, right or biatrial enlargement and supraventricular arrhythmia. Thoracic radiography may reveal pulmonary congestion and pleural effusion and cardiomegaly due to enlarged atria and dilated pulmonary arteries. Heart catheterization shows increased left atrial, right atrial, ventricular and pulmonary artery pressures, that become worse during exercise [9], with possible systemic hypotension and a gradient across the accessory membrane. Cardiac computer tomography and magnetic resonance are used when diagnosis is uncertain [10], but echocardiography usually elucidates the diagnosis [11], the morphology of the atria and venous return and the hemodynamic consequences of the abnormality. If a restrictive opening in the accessory membrane exists, the flow across it will be found both during the systole and diastole [12]. Three dimensional fully-sampled matrix array transoesophageal echocardiography (TEE) offers further information, if needed [13].

Moreover, there cannot be generalized prediction of prognosis as the communicating orifice is the sole determinant of the progression to sequelae. [4] Hence, course and prognosis will vary from case to case. [jiaecho.org]

If the communication between the proximal and distal chambers is not restrictive or if an atrial septal defect allows decompression of the hypertensive left atrium, the prognosis is significantly improved. [chdbabies.com]

The initial evaluation of these patients typically focuses on searching for a pulmonary etiology for arterial desaturation, which often leads to a negative work up. [ncbi.nlm.nih.gov]

Key Concepts Epidemiology Cor triatriatum is an uncommon congenital cardiac anomaly in which either the left (cor triatriatum sinister) or right (cor triatriatum dexter) atrium is divided into two chambers by a membrane. [accesssurgery.mhmedical.com]

Epidemiology Represents 0.1-0.4% of all congenital abnormalities. Associated cardiac lesions include atrial septal defect, anomalous pulmonary venous return, bicuspid aortic valve and PDA. [pedecho.org]

[…] progressive increase in pulmonary artery pressure.2 Syncope, heart failure, and sudden cardiac arrest are well cited.5,6 Early diagnosis by echocardiography is important to expedite surgical cure.2,7,8 References Cor Triatriatum: Background, Pathophysiology, Epidemiology [link.springer.com]

Therefore, active search for cor-triatriatum dexter should be encouraged during echocardiography because this may change the epidemiology of this disease. [jcecho.org]

Pathophysiology In the absence of associated cardiac lesions, the pathophysiology of subdivided left atrium depends on the resulting obstruction to pulmonary blood flow. [accesssurgery.mhmedical.com]

Very few adult patients with cor triatriatum sinistrum and ischemic stroke are reported in the literature, and we discuss the importance of transesophageal echocardiogram and the underlying pathophysiologic mechanisms. [healthcare-bulletin.com]

Given the proposed left atrial pathophysiologic similarities with mitral stenosis, the decision was made to treat with a vitamin K antagonist. [hindawi.com]
