Plain-English summary
A mixed breed female dog was brought in because she kept collapsing over several weeks. Tests showed she had a heart tumor causing severe blockage in the left side of her heart, which led to breathing problems. Unfortunately, despite the veterinary team's efforts, her condition worsened, and she was euthanized just five days after her visit. A necropsy revealed that the tumor had spread within her heart.

Abstract
An adult female mixed breed dog presented for recurrent collapsing episodes over several weeks. Holter evaluation revealed periods of sinus arrest and echocardiography identified a soft tissue mass with subsequent severe dynamic obstruction of the left ventricular outflow tract. The patient was euthanized five days after presentation for severe dyspnea. Necropsy revealed an irregular mass circumferentially lining the left ventricular outflow tract as well as multiple myocardial metastases. The final diagnosis was an undifferentiated pleomorphic endocardial sarcoma.
