| 中文描述 | 動脈狹窄可能發生在瓣膜上方,辦膜上,或是最常見的發生在半膜下方.辦膜下方動脈狹窄是一種發生在狗常見先天性的心臟缺陷.心室的狹窄會導致心室的肥大,而肥大的程度跟狹窄的嚴重性有很大的關係.有些品種的狗可能會有此病,繼承而來的基因問題可能會發生在紐芬蘭狗身上,目前懷疑還有其他狗種可能也會有此影響.這會出現典型忽大忽小聲的雜音,而最大聲的不分會出現在左心底部的位置.診斷藉由心臟超音波檢查,心血管照影,心臟導管.急性突然的死亡發生在年輕的狗身上可能是因為心室的不正常的灌注. |

| 英文描述 | Aortic stenosis may be supravalvular, valvular, or, most commonly, subvalvular; subvalvular aortic stenosis is a common congenital heart defect in dogs. Narrowing of the ventricular outflow tract results in ventricular hypertrophy, with severity related to the degree of stenosis. Several breeds affected; a genetic mode of inheritance is documented in Newfoundland dogs and is suspected in other breeds. There is typically a crescendo-decrescendo murmur, loudest at the left side heart base. Dx by echocardiography, angiocardiography, and cardiac catheterization. A sudden death syndrome in young dogs may be due to inadequate perfusion of ventricular myocardium. |
