Lower MAPSE and TAPSE were associated with worse survival, suggesting systolic longitudinal dysfunction has prognostic value in cats with HCM C07 ECHOCARDIOGRAPHIC ASSESSMENT OF AORTIC ROOT ROTATION IN DOGS WITH CONGENITAL HEART DIS-EASE. N.R. Wyatt 1 , B.A. Scansen 2 . 1 Colorado State University Veterinary Teaching Hospital, Fort Collins, CO, USA, 2 Colorado State University, Fort Collins, CO, USA Rotation of the aortic root, defined as abnormal position of the aortic valvar sinuses relative to surrounding cardiac structures, has been described in children with congenital heart disease but not dogs. Children with tetralogy of Fallot (TOF) show clockwise aortic root rotation and have an increased prevalence of coronary artery anomalies. Coronary artery anomalies are also common in brachycephalic dogs with pulmonary valve stenosis (PS). This study evaluated aortic root rotation in dogs with normal hearts, PS, subaortic stenosis (SAS), and TOF. Aortic root rotation in normocephalic compared to brachycephalic PS dogs was also investigated.
