Hybrid balloon dilation treatment for cor triatriatum dexter in a small breed puppy

Abstract

The authors encountered a 4-month-old, female Shiba dog weighing 4.0 kg, who had been exhibiting abdominal distension and increasing ascites for 2 months. She was brought for further examination and treatment with the chief complaints of ascites and dyspnoea during sleep. The dog was diagnosed with ascites caused by cor triatriatum dexter based on the physical and imaging findings. Under general anaesthesia, she was treated with hybrid balloon dilation under transoesophageal echocardiography guidance. Her postoperative recovery was quite rapid and uneventful. This method appears to be a useful, new, and less-invasive treatment option for cor triatriatum dexter.

Partial Venous Inflow Occlusion under Mild Hypothermia for Membranectomy in a Dog with Cor Triatriatum Dexter

“…Intravascular or hybrid interventions [ 5 , 13 ], as well as surgical correction through membranectomy via cardiopulmonary bypass (CPB) [ 10 ] or VIO [ 11 , 12 ], have been reported as therapeutic methods in dogs with CTD. Interventional techniques have the advantage of being less invasive than open-heart surgery.…”

“…Typically, medical management alone is insufficient to alleviate clinical signs related to CTD [ 9 ]; thus, surgical treatment should be considered for dogs with obvious clinical signs associated with CTD. Several methods, such as transcatheter intervention or surgical resection of the persistent membrane via open thoracotomy, have been reported to treat CTD in veterinary medicine [ 5 , 10 , 11 , 12 , 13 ]. This case report describes the clinical signs, diagnosis, and membranectomy via partial venous inflow occlusion (VIO) under mild hypothermia in a dog presenting with clinical signs associated with CTD.…”
