Abstract
This review focuses on the utility of echocardiographic studies in the diagnosis of tricuspid atresia (TA) and in its management. Tricuspid atresia is a cyanotic congenital heart defect (CHD) accounting for nearly 1.5% of all CHDs. It is generally classified according to the morphology of the atretic tricuspid valve and associated heart defects. Following the description of the anatomic features of TA, echocardiographic features characteristic for TA were illustrated. Subsequent to a review of palliative and corrective procedures to treat TA, echocardiographic evaluation at each stage of Fontan was detailed. The role of echocardiography in the assessment of cardiac defects responsible for interstage mortality was also addressed. It was concluded that echo-Doppler studies are useful in the diagnosis and management of TA.
Highlights
Tricuspid atresia (TA) is a cyanotic, congenital heart defect (CHD) and is defined as congenital absence or agenesis of the morphologic tricuspid valve [1,2,3]
The main focus of this review is to present the role of echocardiography in the diagnosis and management of tricuspid atresia
Other abnormalities may be present in nearly 30% of tricuspid atresia cases [22]; significant of these are the coarctation of the aorta and persistent left superior vena cava, which have therapeutic implications
Summary
Tricuspid atresia (TA) is a cyanotic, congenital heart defect (CHD) and is defined as congenital absence or agenesis of the morphologic tricuspid valve [1,2,3]. It is the third most common cyanotic CHD, and is the most common cause of cyanosis with left ventricular hypertrophy. The main focus of this review is to present the role of echocardiography in the diagnosis and management of tricuspid atresia. Echo features, on the basis of current technology, both with respect to the diagnosis and management, will be reviewed
