2017 ACVIM Forum Research Abstract Program

In conclusion, the dogs with pre-capillary PH had RV dysfunction and dyssynchrony, and RV dyssynchrony may be caused by RV dilation and elevated pulmonary arterial pressure in dogs with pre-capillary PH. Brachiocephalic syndrome (BS) is the result of a combination of anatomical abnormalities in predisposed breeds including stenotic nares and elongated soft palate among others. The signs of BS include laryngeal stridor, rales, exercise intolerance, and higher risk of heat stroke, cyanosis, vomiting, pulmonary hypertension, and right ventricle congestive heart failure. The English bulldog has been reported as a natural model for the study of sleep obstructive apnea syndrome in people, because this breed show alterations like snoring, fragile sleep and hypoxemia. In addition, upper respiratory tract obstruction and inflammation are known to have direct effects on the cardiovascular system and healthrelated quality of life (HRQoL). The aim of this study was to compare quality of life and right ventricular global function before and after corrective surgery for upper respiratory tract obstruction.
