Axenfeld-Rieger syndrome
Axenfeld-Rieger syndrome is a rare spectrum of disorders with an autosomal dominant pattern of inheritance 6. The syndrome incorporates all of 5:
Axenfeld anomaly: posterior embryotoxon and peripheral irido-corneal adhesions
Rieger anomaly: findings of Axenfeld anomaly along with corectopia (m...

Cyanotic congenital heart disease
A number of entities can present as cyanotic congenital heart disease. These can be divided into those with increased (pulmonary plethora) or decreased pulmonary vascularity:
increased pulmonary vascularity
total anomalous pulmonary venous return (TAPVR) (types I and II)
transposition of the ...
Article
Congenital pulmonary stenosis
Congenital pulmonary stenosis refers to congenital narrowing of the right ventricular outflow tract, pulmonary valve, or pulmonary artery.
See pulmonary valve stenosis for a general discussion about this valvulopathy.
Epidemiology
The estimated incidence is 1 in 2000 births.

Sarcoidosis (cardiac manifestations)
Cardiac involvement of sarcoidosis is a manifestation of sarcoidosis which is often asymptomatic, although can be associated with high mortality 8. Autopsy studies show prevalence of ~25% cardiac involvement, yet only 5-10% are found symptomatic 1,2.
Sarcoidosis is a multisystem disorder chara...
Article
Crista terminalis
The crista terminalis is a smooth muscular ridge in the superior aspect of the right atrium, formed following resorption of the right valve of the sinus venosus. It represents the junction between the sinus venarum, the "smooth" portion of the right atrium derived from the embryologic sinus veno...
Article
Interarterial course of the right coronary artery
Interarterial course of the right coronary artery may occur if the right coronary artery (RCA) has an aberrant origin from the left coronary sinus. The interarterial course occurs because the artery passes between the ascending aorta and the pulmonary trunk.
It is an uncommon anatomic variant w...

Mitral annular calcification
Mitral annular calcification refers to the deposition of calcium (along with lipid) in the annular fibrosa of the mitral valve.
Epidemiology
Annular calcification is seen in up to 35% of elderly patients. It is common in females over 65 years, in those with myxomatous degeneration of the mitra...
Article
Aortic valve
The aortic valve (AV) is one of the four cardiac valves. It is the semilunar valve that allows blood to exit the left ventricle (LV). It opens during systole and closes during diastole.
The valve has left, right, and posterior cusps, the bases of which attach around the valve orifice to a fibro...

Cardiac strain imaging
Strain imaging is a cardiac imaging technique that detects ventricular deformation patterns and functional abnormalities before they become obvious as regional wall motion abnormalities on conventional cine imaging or echo. It has become more popular lately due to several technological improveme...
