Abstract

A seven-year-old neutered male cavalier King Charles spaniel presented with exercise intolerance, cough anddyspnea.A grade 5/6 cardiac systolic murmur was audible in the area of the left cardiac apex.On a thoracicradiograph, the cardiac silhouette was remarkably enlarged and pulmonary edema was observed.Echocardiographyshowed marked mitral regurgitation and an enlarged left atria (LA/Ao: 3.5).Based on these findings, the dog was diagnosed with severe mitral regurgitation, following a rupture of the chordae tendineae.The mitral regurgitation was treated with mitral valve plasty using cardiopulmonary bypass.Two months aftersurgery, the dog was clinically normal and an echocardiography revealed that mitral regurgitation was conspicuouslyreduced.This case suggested that mitral regurgitation in cavalier King Charles spaniels can betreated with mitral valve plasty.
