Echocardiography has been proved use­ful in diagnosing many of the congenital anomalies non-invasively. Our case had type 1B tricuspid atresia diagnosed on an­giocardiography. Echocardiography re­vealed highly suggestive features of tri­cuspid atresia.

 Case report

L. B., a 4 year old female child presented to us with the complaints of repeated attacks of anoxic spells and respiratory tract infection. The child was born of full term normal deli­very of non-consanguinous parents. Cyanosis was noticed since birth. Clinical examination revealed central cyanosis and clubbing of all the four limbs, normal situs and no skeletal deformities. Cardiovascular system examination revealed prominent `a' waves in neck veins, apex beat in the 5th LICS 1 cm. outside MCL suggesting left ventricular volume overload. There was a striking absence of the left para­sternal pulsations. On auscultation she had a pansystolic murmur along the left sternal edge in the 3rd and 4th LICS, left ventricular S 3 and single second sound. ECG showed left axis deviation (axis QRS in frontal plane -60°) and left ventricular hypertrophy. X-ray chest confirmed situs solitus, levocardia, left ventri­cular hypertrophy, prominent right atrium and pulmonary bay with pulmonary oligemia. Clinical diagnosis of tricuspid atresia was made. Catheter and angiocardiography revealed type 1B tricuspid atresia.

The child was subjected to echocardiographic studies. Echocardiogram revealed large left ventricle (LVIDd = 5.0 cm) LVIDs = 4.5 cm) and brisk excursion of anterior mitral leaflet reaching upto the anterior chest wall. Tricuspid valve could not be obtained inspite of repeated attempts, and right ventricular cavity was absent; interventricular septum merged with anterior chest wall echoes. Mitral valve echo showed significant prolapse of the anterior mitral leaflet. (See [Figure 1] on page 254).


Echocardiography in congenital heart disease has been reported by various in­vestigators. [1],[2],[3],[4],[5] Highly suggestive echo­cardiographic feature of tricuspid atresia are (1) visualization of single AV valve echo. (2) diminutive or absent right ven­tricular cavity (3) large left ventricular chamber and (4) brisk excursion of an­terior mitral valve in early diastole tou­ching the interventricular septum due to increased left ventricular volume over­load. An interesting finding of prolapse of mitral leaflet is described. [6] This has been reported as being very common ii this malformation. All these features were observed in our case.
