Plain-English summary
A 13-year-old neutered male Pekingese was brought in for breathing problems and a swollen belly after being diagnosed with pulmonary hypertension over a year earlier. Tests revealed that he had a rupture of the chordae tendineae (the heart strings) of the tricuspid valve, which was causing fluid buildup in his abdomen and worsening heart failure. The vet drained the excess fluid and provided additional medical treatment, which helped the dog feel better, but he was sent home with a poor prognosis.

Abstract
BACKGROUND: Rupture of the chordae tendineae of the tricuspid valve is rare in dogs. We report the case of a dog with tricuspid valve chordal rupture secondary to pulmonary hypertension. CASE DESCRIPTION: A 7.7-kg, 13-year-old neutered male Pekingese on annual heartworm prevention presented with respiratory distress. The patient received a diagnosis of pulmonary hypertension and received medical treatment. However, the patient re-presented 405 days post-diagnosis with dyspnea and an increased abdominal circumference. Transthoracic echocardiography showed ruptured chordae tendineae of the tricuspid valve, and abdominal ultrasound identified significant ascites associated with worsening right congestive heart failure. The patient improved after draining ascitic fluid and extra medical treatment, but was released with poor prognosis. CONCLUSION: Ruptured chordae tendineae of the tricuspid valve should be considered in patients with pulmonary hypertension.
