Plain-English summary
A 10-year-old male neutered Cavalier King Charles Spaniel was brought in for severe weakness and trouble breathing. He had a history of heart problems and was diagnosed with congestive heart failure, a heart attack, and a blood clot in his heart. Unfortunately, his condition was very serious, and he was euthanized due to the poor prognosis. A postmortem exam confirmed the heart attack was likely caused by a blood clot that broke off from a tear in the heart's wall.

Abstract
A 10-year-old male neutered cavalier King Charles Spaniel with a 1-year history of degenerative mitral valve disease presented for dyspnea and severe weakness. He was diagnosed with congestive heart failure, systolic dysfunction, presumptive myocardial infarction and a left atrial thrombus based on thoracic radiographs, electrocardiogram and echocardiographic findings. Clinical signs also suggested right foreleg embolism. The dog was euthanized due to the grave prognosis and a postmortem evaluation was performed. The postmortem examination confirmed myocardial infarction and was thought to be due to embolic showering from the thrombus attached to a partial thickness left atrial endocardial tear.
