Cardiac Anomalies in Two White-Tailed Eagles (Haliaeetus albicilla) in Sweden.

J Wildl Dis 2021 Apr;57(2):413-417

Department of Pathology and Wildlife Diseases, National Veterinary Institute, 751 89, Uppsala Sweden.

Severe cardiomegaly with an atrial septal defect was discovered during necropsy of a subadult White-tailed Eagle (Haliaeetus albicilla) found dead in the wild. A thin membrane composed of fibromuscular tissue separated the left atrium into two chambers, most consistent with that described for cor triatriatum sinister (CTS) in other species. Seventeen months later, necropsy of an adult White-tailed Eagle again revealed CTS. Read More

Cor triatriatum sinister with left anomalous pulmonary venous drainage to innominate vein: what to do with the vertical vein?

Gen Thorac Cardiovasc Surg 2021 Apr 2;69(4):731-735. Epub 2020 Nov 2.

Department of Cardiovascular Surgery, Saitama Children's Medical Center, Saitama, Japan.

We treated a surgical case of a 47-day-old male infant diagnosed with an unusual type of cor triatriatum sinister (CTS) with left anomalous pulmonary venous drainage to the innominate vein via a vertical vein. After preoperative hemodynamic assessment of pulmonary venous (PV) return, this patient underwent a resection of the fibromuscular membrane between the accessory and the true left atrial chambers, concomitant with vertical vein banding to facilitate a left PV return through a common pulmonary venous collector (CPVC). Catheterization three months after this surgery revealed no obstruction of the PV return to the mitral orifice as well as good growth of the CPVC as a left PV return pathway. Read More

Cor Triatriatum Associated with Total Anomalous Pulmonary Venous Connection: A Rare but Plausible Combination.

J Chest Surg 2021 Apr;54(2):143-145

Department of Thoracic and Cardiovascular Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.

In a newborn in whom cor triatriatum was missed on echocardiography, infracardiac total anomalous pulmonary venous connection was successfully repaired with the aid of cardiac computed tomography (CT). In rare combinations, as in this case, an accurate diagnosis prior to surgery, which is of vital importance for successful repair, can be made through a high index of suspicion and the use of a supplemental imaging modality such as CT.

Supracardiac total anomalous pulmonary venous connection with cor triatriatum sinister: A rare diagnosis confirmed by saline contrast echocardiography.

Echocardiography 2020 12 27;37(12):2168-2170. Epub 2020 Oct 27.

Department of Cardiology, All India Institute of Medical Sciences, New Delhi, India.

In cor triatriatum sinister, the left atrium is divided by a membrane into a proximal and a distal chamber. Usually proximal chamber receives all the pulmonary veins and drains through an opening in the dividing membrane into distal chamber, which empties into left ventricle through the mitral valve. Rarely, the two chambers lack a communication and there is associated total anomalous pulmonary venous connection (TAPVC). Read More

Department of Cardiology, Ogaki Municipal Hospital, Ogaki, Japan.

A key to the success of catheter ablation in complex congenital heart disease is an accurate delineation of the anatomy. Here we describe the efficiency of intracardiac echocardiogram in guiding the catheter ablation of persistent atrial fibrillation in a 55-year-old Japanese male with cor triatriatum sinister. Echo imaging provided a detailed three-dimensional anatomy of the whole left atrium and identified an ideal trans-septal puncture site that allowed catheter access to both the accessory and main chambers of the left atrium.

Cardioembolic stroke in a young male with cor triatriatum sinister: a case report.

Eur Heart J Case Rep 2020 Jun 3;4(3):1-6. Epub 2020 May 3.

Department of Cardiology, University of Maryland Medical Center, 22 South Greene Street, Baltimore, MD 21201, USA.

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.
