Echocardiographic Study Of Myocarditis-type Canine Parvovirus Disease

In order to evaluate the diagnostic application of ultrasound in myocarditis-type ofCPV disease, echocardiography was used to study the changes of cardiac structure andfunction in dogs from 4 to 6 weeks old which were artificially infected with CPV. The highquality images were consistently obtained while 5.0MHz and 7.0 MHz probe was put onthe left pectoral apterlae of canine lied down at belly up. The images in myocarditis-typeof CPV diasease showed several apparently different traits with those in enteritis-type ofCPV disease, namely, pericardiac effusion, geometrical changes of left ventricle,incrassation of ventricular septum moving lean to left, decreased moving extent ofventricular septum, dilation of right ventricle and ventricular wall hypertrophy. Thechange of heart is the same as the results of histo-pathology. All of our resultsdemonstrated that echocardiography is a useful non-invasive real-time diagnostictechnology to myocarditis-type of CPV disease, which was used to evaluate cardiacstucture and function in canine. During the disease of myocarditis CPV disease, the rapidmultiplication of CPV in the myocardium cell, and myocardium damage may act as aleading role during the change of cardiac stucture and function in canine. So we shouldcheck and cure it as early as possible, so as to avoid cardiac enlargement, nonfunction andthreat to life.
