title: Uhl's anomaly in the mink. Partial absence of the right atrial and ventricular myocardium.
abstract: Congenital marked hypoplasia of the right atrial and ventricular myocardium (Uhl's anomaly), without other cardiac anomalies, was observed at autopsy in a mink. The animal died unexpectedly without previous symptoms at the age of 2 years, suggesting that the cause of sudden death was acute congestive heart failure. This cause demonstrates that this malformation can occur in species other than man. Embryologically, this anomaly might be due to myocardial injury to the right cardiogenic fold at a relatively early stage of embryogenesis.
