“…In a study of 211 adult patients (16) , Sugseng et al reported an excellent visualisation by 3D-MTEE of the posterior cardiovascular structures such as the mitral valve (in up to 91 % of cases), the inter-atrial septum (84%) and the left atrial appendage (86%). 3D-MTEE was also successfully used in the diagnosis of CTS, being able to accurately visualise the extra-membrane and showing its exact morphology (17,18) .…”

“…On the basis of its relationship to the mouth of the appendage, it can readily be distinguished from the supramitral ring 7 . The addition of Doppler technology permits estimation of the gradient between the atrial compartments 7,100,103,105–107,109–116 . The addition of cardiac computed tomography, or magnetic resonance imaging, serves to enhance recognition of the anatomical details (Figures 6A–C and 7A–C).…”

Background and Aim The morphological variations when one, or both, of the atrial chambers is subdivided, are many and varied. We sought to address clinical presentations, potentially misdiagnosed cases, diagnostic modalities, surgical approaches, and outcomes of this “family” of uncommon lesions. Methods A total of 193 published investigations were synthesized. Diagnostic information was provided by clinical presentation, and multimodality imaging studies. Results Almost three‐quarters of patients with divided atrial chambers present during infancy with severe pulmonary hypertension and cardiac failure. Associated cardiac and extra‐cardiac defects are present in between half and nine‐tenths of cases. Acquired division of the left atrium has been reported after the Fontan operation, orthotopic cardiac transplantation, and complicated aortic valvar infective endocarditis. Surgery under cardiopulmonary bypass remains the definitive treatment. Balloon dilation may be considered in anatomically compatible variants in the setting of cardiac failure and pregnancy as a bridge todefinitive treatment. Overall, mortality has been cited between nil to 29%. Presentation during infancy, associated congenital anomalies, pulmonary hypertension, and surgery in the previous era, have been the reported causes of death. The operative survivors have long‐term favourable outcomes, with near normal cardiac dimensions and low risk of recurrence. While asymptomatic patients with division of the right atrium do not need treatment, surgical resection of the dividing partition under cardiopulmonary bypass is recommended in symptomatic patients with complex anatomy, the spinnaker malformation, or associated cardiac anomalies. Balloon dilation may be considered in uncomplicated patients with less obstructive lesions. Hybrid intervention and endoscopic robotic correction also have been performed. Conclusions Resection of the dividing shelf allows the survivors to regain near normal dimensions with a low risk of recurrence. We submit that an increased appreciation of the anatomic background to division of the atrial chambers will contribute to improved surgical management.

Case Report: Fortuitous discovery of cor triatriatum sinister in a young adult

et al. 2022

Cor triatriatum is an extremely rare cardiac congenital malformation characterized by subdivision of the left atrium into two chambers. This division is due to the presence of an abnormal fibromuscular membrane interrupted by one or more openings that communicate the two chambers. The size and number of those orifices is variable, affecting the age of onset of symptoms and their severity. Our case describes the fortuitous discovery of this pathology in a young adult in her forties, following the finding of atrial fibrillation during a preoperative assessment of a strangulated hernia. The cardiac ultrasound allowed in our case to invoke the diagnosis, confirmed thereafter with an angioscanner. Surgical resection was not required in our patient who was put on medical treatment involving a beta-blocker to reduce atrial fibrillation and an anticoagulant treatment to decrease the thromboembolic risk, with a good clinical evolution. It seems therefore interesting to consider this uncommon pathology which may be latent for a long time, manifesting after some physiological or pathological situations.
