“…Cor triatriatum dexter is characterized by a right atrium that is divided into two compartments; this is due to the presence of a persistent membrane that acts as a septum between the cranial and caudal chambers [ 4 ]. As most dogs with CTD have ascites due to the blockage of venous blood flow into the right side of the heart, primarily from the CdVC entering the caudal accessory chamber, abdominal distention is commonly observed on physical examination [ 6 , 9 , 11 , 12 ].…”

“…However, clinical signs and physical examination findings may vary depending on the CTD type. Partington et al [ 4 ] reported the classification of CTD into four types based on the vascular structure opening into the right atrium. Type I CTD opens the CrVC, the CdVC, and coronary sinus (CS) into the caudal chamber.…”

“…Type IV CTD opens the CrVC and the CdVC into the cranial chamber, while the CS opens into the caudal chamber. According to previous studies, type III is presumed to be the most common in dogs [ 5 , 6 , 11 , 12 ], and there is a single case of type II [ 4 ]. In dogs with type II CTD, jugular vein distention and pulsation may be observed as well as hepatojugular reflux [ 4 ].…”

Cor triatriatum dexter (CTD) is an uncommon congenital cardiac anomaly in dogs. This case report describes successful membranectomy for CTD via partial venous inflow occlusion under mild hypothermia in a dog. A 7-month-old intact male mixed-breed dog weighing 20.5 kg presented with a history of abdominal distention, lethargy, and anorexia. Clinical examination, radiography, echocardiography, microbubble testing, and computed tomography revealed a remnant right atrium membrane obscuring the venous blood inflow from the vena cava. Considering the potential risk of re-stenosis following interventional treatment, curative resection involving surgical membranectomy via venous inflow occlusion was performed. By performing partial venous inflow occlusion under mild hypothermia (34.5 °C), sufficient time was obtained to explore the defect and resect the remnant membrane. The dog recovered without any complications, and the clinical signs were relieved. This case illustrates that partial venous inflow occlusion under mild hypothermia is feasible for achieving curative resection of cor triatriatum dexter in dogs.

“…Recently, a CTD with unusual morphology was described in a miniature schnauzer presenting jugular pulse and pleural effusion. The dog had both the cranial and caudal vena cava entering the CaRA, whereas the coronary sinus entered both CaRA and CrRA by two communications [18].…”

Percutaneous balloon dilation was performed in a Rhodesian Ridgeback and in an American Staffordshire Terrier affected by cor triatriatum dexter (CTD). Both cases had ascites without jugular venous distension or pleural effusion. In both dogs the CTD presented a perforated membrane but with different morphology: in one case the coronary sinus entered the caudal chamber of the CTD together with the caudal vena cava. In the other case, the coronary sinus communicated with the cranial chamber of the CTD together with the cranial vena cava. Percutaneous balloon dilation of the CTD was successfully performed, and both dogs had uneventful surgery recoveries. At two years of follow-up, the dogs were free from clinical signs and cardiac medication.
