Abstract:
The presented study tries to point put characteristic history, clinical examination, elecrocardiography and echocardiography in 190 dogs, which were found to be affected, or suspected to be affected with subaortic stenosis(SAS) from 1996 until 2003 at the service of cardiology of the I. Medical Clinic, Veterinary University, Vienna. Morover it should test the hypothesis that the distribution of breeds being affected by SAS in Austria varies from other countries and of positive correlation of heartrate and pressure gradient. The collected facts are apt to be basis of screening-programm? As a result the heartrate showed little correlation to the pressure gradient. The grade of the disease dependent on the pressure gradient of the stenosis, showed a mild expression in most of the examined cases. The frequency of aortic regurgitation, which was detected at 29% of the dogs, incresees with rising level of the disease. The enddiastolic posterior wall and septum thickness showed little correlation with the bodyweight but at least?? more correlation was found than between the enddiastolic leftventricular posterior wall, as well as the thickness of the septum and the pressure gradient. At this study dogs from 45 breeds, including crossbreeds, were used. In contrast to European coutries, USA and Australia, most affected were the Golden Retriever, followed by the Boxer and the German Shepard. The German Shepard dog is presented 1,6 times more than the Golden Retriever at our hospital. Golden Retriever was presented 3 times more than the Boxer. The conclusion of these study is, that the possible occurence of SAS in the Boxer is high but in the German Shepard dog rather low. This study might be a base for a screening-programm in Austria for Golden Retrieve, Boxers and Bullterriers.
