Divided left atrium with totally anomalous drainage of normally connected pulmonary veins.

Cardiol Young 2022 Apr 29:1-3. Epub 2022 Apr 29.

Department of Paediatric Cardiology, Royal Brompton Hospital, London, UK.

In the December 2021 issue of Cardiology in the Young, Hubrechts and colleagues, from Brussels and Leuven in Belgium, describe their experience in which the pulmonary veins were normally connected to the morphologically left atrium. By virtue of the presence of a shelf dividing the morphologically left atrium, however, the venous return was to the morphologically right atrium, with no evidence of formation of the superior interatrial fold, meaning that there was no obstruction of flow into the systemic venous circulation. The question posed by the Belgian authors is whether the shelf dividing the morphologically left atrium is a deviated primary atrial septum, as the arrangement has previously been interpreted.

Cor triatriatum dexter: a rare incidentaloma.

Acta Biomed 2022 Apr 14;93(S1):e2022093. Epub 2022 Apr 14.


Cor triatriatum dexter (CTD) is an extremely rare finding resulting from the persistence of the right valve of sinus venosus. It is a congenital cardiac anomaly defined by an abnormal septation of the atrium leading to inflow obstruction to the respective ventricle. Multimodal diagnostic modalities are necessary to characterize it for an optimal patient management. Read More

Cor triatriatum dexter of unusual morphology in a miniature schnauzer.

J Vet Cardiol 2022 Mar 4;41:165-171. Epub 2022 Mar 4.

Department of Small Animal Clinical Science, School of Veterinary Science, Institute of Infection, Veterinary and Ecological Sciences, University of Liverpool, Neston, CH64 7TE, UK.

A five-year-nine-month-old, male entire, miniature schnauzer presented for further investigation of pleural effusion. Echocardiography revealed a perforated membrane dividing the right atrium into two chambers: the true right atrium (a small, lower-pressure, cranioventral chamber communicating with the tricuspid valve and right ventricle) and the accessory right atrium (a larger, higher-pressure, caudodorsal chamber), consistent with a cor triatriatum dexter. This was confirmed using computed tomography angiography. Read More

Mini right axillary thoracotomy for congenital heart defect repair can become a safe surgical routine.

Cardiol Young 2022 Feb 18:1-4. Epub 2022 Feb 18.

Novick Cardiac Alliance, Memphis, TN, USA.

Objective: Owing to its obvious cosmetic appeal, minimal invasive repair of congenital heart defects (CHDs) through the mini right axillary thoracotomy is becoming routine in many centres. Besides cosmesis, and before becoming a new norm, it is important to establish its outcomes as safe compared to repairs through traditional median sternotomy.

A six-chambered heart: cor triatriatum sinister with double-chambered right ventricle in association with ventricular septal defect.

Egypt Heart J 2022 Feb 16;74(1):10. Epub 2022 Feb 16.

Department of Cardiothoracic and Vascular Surgery, Post Graduate Institute of Medical Education and Research, Chandigarh, 160012, India.

Background: Cor triatriatum has been described as a heart with three atria in which the left atrium (cor triatriatum sinistrum) or right atrium (cor triatriatum dextrum) is divided into two compartments by a fold of tissue, a membrane, or a fibromuscular band. Double-chambered right ventricle, on the other hand, is identified by the presence of an anomalous muscle bundle dividing the right ventricle into two chambers.

Case Presentation: Here, we describe the case of a child who had a combination of both of these rare entities, effectively creating a heart with six chambers. Read More

Cureus 2022 Feb 4;14(2):e21898. Epub 2022 Feb 4.

Cardiology, Hospital Distrital de Santarém, Santarém, PRT.

Cor triatriatum is a congenital atrial abnormality, which comprises a membrane that divides the atrium into two chambers. Symptoms can arise either due to the obstructive nature of this membrane or related to other associated anomalies, such as atrial septal defects or abnormal pulmonary venous return. The authors report the case of an adult male, in whom an incidental finding of cor triatriatum sinistrum was documented in association with mitral valve prolapse. Read More
