Plain-English summary
An 8-year-old Labrador retriever was diagnosed with primary pulmonary hypertension after showing signs of exercise intolerance that worsened over time, eventually leading to heart failure. The diagnosis was confirmed through ultrasound of the heart, which revealed significant changes in the heart's structure and high blood pressure in the lungs. Unfortunately, the condition is serious and progressive, and the dog experienced severe thickening of the blood vessels in the lungs. Treatment options for pulmonary hypertension can vary, and it's important for pet owners to discuss management strategies with their veterinarian.

Abstract
Primary pulmonary hypertension was diagnosed in an eight-year-old labrador retriever on the basis of echocardiographic findings of severe right ventricular eccentric hypertrophy, abnormally high systolic and diastolic pulmonary arterial pressures calculated by applying the modified Bernoulli equation to the tricuspid and pulmonary insufficiency peak velocities, and the absence of any underlying disease known to cause secondary pulmonary hypertension. The clinical abnormalities developed gradually, from exercise intolerance starting early in life to terminal right-sided congestive heart failure. Consistent histopathological findings were severe intimal and medial thickening of small arteries and arterioles that led to vascular obliteration.
