Cardiovascular System - Developmental Pathology

Congenital abnormalities occur relatively commonly in young (approximately 1% all human births). May produce dramatic clinical signs or signs may be vague, such as failure to thrive. Clinical signs may become more apparent as the animal grows and activity levels increase.

The aetiology of congenital defects of the heart and great vessels are mostly unknown. Possible contributing factors include:

Genetic; E.g. Mutation in the ova or sperm or mutation in the zygote.
Environmental; Includes infection (usually viral), chemical, nutritional and physical factors.

Understanding the normal development of the heart and great vessels allows an understanding of the morphology and pathology of the congenital abnormalities seen in mammals.

Tricuspid Dysplasia

Miscellaneous

Peritoneo-pericardial Diaphragmatic Hernia

Represents an embryological malformation of the ventral midline with communication to varying degress of the pericardial sac and the peritoneal cavity. Often associated with other malformations for example sternal deformities and ventricular septal defects. Usually results in gastrointestinal or respiratory signs. Visible radiologically as a round cardiac silhouette which merges with the diaphragm. The trachea will be displaced dorsally. Intestines may be visible on radiographs. Repaired surgically.

Ectopia Cordis

The heart is normal in anatomy but situated in an abnormal location within the body. Cattle and pigs show the highest incidence. The heart may be found in the cervical region or the abdomen.

Endocardial fibro-elastosis

Seen in Burmese kittens. Collagen and elastin are deposited in the endocardium, limiting its function. Animals are often found dead at 2-3 months of age.

 ===Tricuspid Dysplasia===
-Tricuspid regurgitation results in volume overload of the right atrium and may progress to right heart failure.<br>
-'''''Ebstein's Anomaly:''''' Atrioventricular ring is displaced ventrally into the right ventricle so that part of the wall of the right atrium is made up of ventricular wall.
-''Incidence:''
-*Second most common congenital anomaly seen in cats.
-*Also reported in large breeds of dog including Weimeraner.
-''Clinical Signs:''
-*Often the murmur is the only clinical sign; low grade and pansystolic with increased intensity over the tricuspid area.
-*May also see right sided failure, signs include; ascites, hepatomegaly and splenomegaly.
-''Diagnosis:''
-*Right ventricular enlargement on radiology and ECG.
