Plain-English summary
A 4-year-old Airedale terrier was brought in for fainting episodes after exercise, and it was discovered she had a tumor in her heart. Surgeons used a special technique to temporarily stop blood flow while they removed the tumor, which was a type of cartilage cancer called chondrosarcoma. The surgery was successful, and the dog no longer experienced fainting spells afterward. However, about 10 months later, the tumor returned, and she sadly passed away a year after the surgery.

Abstract
Use of normothermic venous inflow occlusion enabled removal of an intracardiac tumor in a 4 yr old, 27 kg, spayed female Airedale terrier with a history of appendicular osteosarcoma and recent exertional syncope. Inflow venous occlusion via a median sternotomy thoracotomy without hypothermia was used to access the mineralized mass within the right ventricular outflow tract. Duration of circulatory arrest was 70 s for this beating heart surgery. A circumscribed intracardiac chondrosarcoma tumor was marginally resected in this dog, successfully alleviating exertional syncope and restoring a normal echogenic appearance of the right heart. Asymptomatic intracardiac chondrosarcoma recurrence and pulmonary metastasis was detected at 309 days and cardiopulmonary arrest occurred 372 days following intracardiac surgery. Use of inflow occlusion is a viable technique for select intracardiac tumors in dogs with preoperative planning.
