Cor triatriatum sinister is a rare congenital cardiac anomaly. The anomaly is caused by a fibromuscular membrane that divides the left atrium into two cavities. This membrane can lead to the obstruction of left atrial flow and also create pulmonary venous hypertension. Pulmonary arteriovenous malformation (PAVM) is notorious for its aberrant blood flow between the pulmonary arteries and veins. Herein, we report a case of a 4-year-old toddler who had a unique form of pulmonary hypertension presenting with cor triatriatum sinister and diffuse PAVM. After the surgical treatment of cor triatriatum sinister, both pulmonary arteriovenous malformation and pulmonary hypertension disappeared.

AbstractCor triatriatum sinister is an uncommon congenital cardiac anomaly accounting for 0.1% of all congenital cardiac malformations, with an anomalous venous return being a frequently associated condition. We present the case of a 14-year-old girl misdiagnosed as having an atrial septal defect with pulmonary hypertension who actually had a cor triatriatum with a left upper anomalous pulmonary venous return to the innominate vein.

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

Cor triatriatum sinister is a rare congenital cardiac anomaly in which a fibromuscular membrane divides the left atria into 2 chambers. It is even rarer when present at an adult age. Symptoms and presentation of the patient depend on the size of the opening into the membrane through which 2 chambers of left atrium communicate with each other. Cor triatriatum sinister rarely remains asymptomatic till adulthood. In adults symptoms of Cor triatriatum sinister mimic the symptoms of mitral stenosis. Corrective surgery is the choice of treatment, but when it present as an emergency case especially at an early age, balloon dilatation of the membrane opening is done. Elective balloon dilatation of membrane opening at an early age diagnosed with Cor triatriatum sinister followed by corrective surgery at an adult age can be a safer option compared to direct corrective surgery at an early age.  We present a case of a 25-year-old female who was diagnosed first time at this age as cor triatriatum sinister and treated successfully with corrective surgery.

Cor triatriatum sinister (CTS) is a rare congenital cardiac anomaly and is mainly corrected through conventional surgery through sternotomy. We described our successful novel surgical technique of totally robotic correction of CTS in one case of CTS with concomitant repair of atrial septal defect using da Vinci SI Surgical System (Intuitive Surgical, Inc, Sunnyvale, CA USA) with excellent surgical outcome. We conclude that robotic correction of CTS is a feasible and safe alternative to conventional surgical technique.

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.

AbstractCor triatriatum sinister is a very rare cardiac anomaly that may lead to pulmonary hypertension, right ventricular dilation, and eventually right heart failure. We report a case of a toddler who presented with respiratory distress and cardiomegaly and was found to have cor triatriatum sinister with a restrictive communication, decompressing vertical vein, pulmonary hypertension, severe tricuspid regurgitation, and severe right ventricular dysfunction. She underwent a successful surgical repair, with normalisation of right ventricular function and pulmonary artery pressure.

Cor triatriatum sinistrum (CTS) is a rare congenital cardiac anomaly characterised by an abnormal septum within the left atrium impairing blood flow to the left ventricle. We report the case of a two-month-old male infant who presented with symptoms of heart failure since the age of two weeks. He was admitted to a local hospital and was managed with antibiotics because of the impression of pneumonia. Due to persistent unresolved tachypnoea and tachycardia, he was referred to Sultan Qaboos University Hospital, Muscat, Oman, in 2019 for cardiac evaluation which confirmed a diagnosis of isolated CTS with severe stenosis and pulmonary hypertension. He underwent an urgent surgical excision of the membrane with uneventful recovery.

Ligation of the ductus arteriosus of the fetal sheep produces severe pulmonary hypertension at birth. Standard tissue bath techniques were used to study third- and fourth-generation pulmonary arteries and veins isolated from fetal sheep with pulmonary hypertension created by ligation of the ductus arteriosus 11–12 days before birth as well as from age-matched control sheep. Vessels pretreated with indomethacin and propranolol were submaximally preconstricted with norepinephrine before exposure to A-23187 (10(-8) to 3 x 10(-7) M), sodium nitroprusside (SNP; 10(-9) to 10(-5) M), and nitric oxide (NO) gas (1-973 ppm). Pulmonary veins in both control and ligated animals relaxed similarly and completely to A-23187, SNP, and NO. Control pulmonary arteries relaxed by 16 +/- 2% to A-23187 and relaxed completely to SNP and NO, with concentration-response curves shifted rightward of those observed in pulmonary veins. Pulmonary arteries from ligated animals did not relax at all to A-23187. SNP relaxations in ligated arteries were shifted rightward of control. Ligated arteries relaxed by only 11 +/- 5% to the highest dose of NO. However, control and ligated pulmonary arteries relaxed similarly to 8-bromoguanosine 3',5'-cyclic monophosphate (8-bromo-cGMP; 10(-5) to 10(-3) M) and atrial natriuretic peptide (10(-9) to 10(-7) M). These data are most simply explained by decreased arterial vascular smooth muscle sensitivity to NO at the level of soluble guanylate cyclase.
