The present study was performed to investigate the prevalence of mitral valve prolapse (MVP) in dogs, and to evaluate protrusive changes in the mitral valve by echocardiographic examination. Thirty-five dogs were examined, including those observed clinically normal, and animals with suspected cardiac disease displaying lethargy, coughing, dyspnea, exercise intolerance, or syncope. The echocardiographic examination revealed 19 (54.2%) of the dogs to have MVP, whereas 16 (45.7%) had a normal mitral valve. It was concluded that the degree of protrusion of the mitral valve in systole differs in individual dogs with mitral prolapse. MVP, determined to be widespread in dogs, can be reliably diagnosed by means of echocardiographic findings.
