Cleft Lip/Palate - Midline Defective closure of the lip in the midline is much rarer than paramedian unilateral or bilateral cleft lip. It may be complete, with involvement of the alveolar ridge and palate, or incomplete. In some cases, a midline cleft represents a serious defect of the... Dr George F Tawagi; Dr Harm-Gerd Blaas 01 January 2001 Microphthalmia Microphthalmia indicates reduction in volume of the eye and is generally characterized by a corneal diameter of less than 10 mm or an anteroposterior globe diameter of less than 20mm. There may be marked variation in the severity of the lesion. Occasionally po... Dr George Tawagi; Dr Karl Gloning 01 January 2001 Aortic Valve Stenosis Aortic stenosis denotes some degree of obstruction to flow through the aortic valve due to developmental deformity of the valve. The abnormal valve will be restricted in motion, usually bicuspid or even unicuspid instead of having three leaflets. The stenos... Dr Gerald Marx; Dr Gurleen Sharland reviewed 01 January 2011 Tricuspid Valve - Dysplasia This condition is seen much more commonly in the fetus than the infant as it is readily detected in utero because of cardiomegaly. Anatomically, the tricuspid valve is nodular and thickened. Secondary lung hypoplasia as a result of long-standing compressi... Dr Gurleen Sharland 01 January 2001 Cardiomyopathy A cardiomyopathy can be due to a variety of causes such as storage disease, endocardial fibroelastosis or viral infection. Damage to cardiac muscle occurs which results in diminished cardiac function and cardiac failure manifested by hydrops fetalis. There is... Dr Gurleen Sharland 01 January 2001 Tricuspid Valve - Unguarded In this very rare condition, the tricuspid valve leaflets are rudimentary. The condition is usually fatal in utero or in early neonatal life. Tricuspid valve replacement is a theoretical possibility if the neonate survives to a surgical procedure. Valve... Dr Gurleen Sharland 01 January 2001 Tumour - Pericardial Pericardial teratoma is a rare condition in the fetus. This cystic tumour can compress the heart and cause fetal hydrops depending on its site. It tends to be related to the right atrium. It is histologically benign but because of its size, it will usually l... Dr Gurleen Sharland 01 January 2001 Ebstein's Malformation in Corr TGA If an apically displaced valve is seen in the posterior ventricle this is indicative of a discordant atrioventricular connection, as displacement of the mitral valve into the left ventricle is exceedingly rare. In this condition, a normally situated left... Dr Gurleen Sharland 01 January 2001 Discordant Atrioventricular (AV) Connection with Discordant VA Connection In this condition, the morphological right atrium is usually situated in the normal position but is connected to the morphological left ventricle, which in turn gives rise to the pulmonary artery. The morphological left atrium is connected to the morphological... Dr Gurleen Sharland 01 January 2001 Transposition of the Great Arteries (TGA) - SImple The great arteries are reversed in their connection to the ventricles with the aorta arising from the right ventricle and the pulmonary artery from the left. The newborn will present soon after birth with cyanosis. Enlarging the atrial communication by ba... Dr Gurleen Sharland 01 January 2001
