1987~1997年に宮崎県内の食肉検査所で採取された豚の奇形心324例を解剖学的に観察した,大動脈狭窄が224例(69.1%)で最も多く,次いで心内膜床欠損37例(11.4%),心室中隔欠損32例(9.9%)であった.大動脈狭窄と心内膜床欠損が多いことはこれまでの報告とほぼ一致し,豚の心奇形の特徴と考えられた.
Morphological observation was conducted on 324 swine cases of the malformed heart collected at meat inspection centers in Miyazaki Prefecture from 1987 to 1997. The incidence was 0.07% and the most frequently occurring was aortic stenosis observed in 224 cases (69.1%), followed by endocardial cushion defect in 37 cases (11.4%) and ventricular septal defect in 32 cases (9.9%). Aortic stenosis and endocardial cushion defects might be the most common cardiac anomalies in swine, as proviously described.
