Morphology of 324 Swine Cases of Cardiac Anomalies

Abstract

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.
