The value of 2-D Doppler echocardiography in the evaluation of asymptomatic patients with Mustard operation for transposition of the great arteries

2-D Doppler echocardiography was used to assess the occurrence of haemodynamic abnormalities in 45 asymptomatic patients, aged 4 to 16 years (median 7·4) after a Mustard operation for transposition of the great arteries. The findings were compared with those derived from cardiac catheterization. Thi...

Description
Summary:2-D Doppler echocardiography was used to assess the occurrence of haemodynamic abnormalities in 45 asymptomatic patients, aged 4 to 16 years (median 7·4) after a Mustard operation for transposition of the great arteries. The findings were compared with those derived from cardiac catheterization. Thirty-five cardiac lesions were correctly diagnosed by 2-D Doppler echocardiography in 23 patients, but on six occasions, minor abnormalities were missed. 2-D Doppler echocardiography demonstrated systemic venous pathway obstruction of more than 3 mmHg at cardiac catheterization in nine patients, and in five of the six patients with pulmonary venous channel obstruction. A left ventricular outflow tract obstruction (pressure difference > 15 mmHg) was diagnosed correctly by Doppler echocardiography in seven patients. Baffle leakage was found in two patients with a left to right shunt of 25% or more of pulmonary bloodflow, but was missed in five out of nine patients with small shunts. Tricuspid regurgitation was well defined in eight patients, The absence of symptoms and a routine examination after a Mustard operation do not rule out haemodynamic abnormalities. However, these, with the possible exception of minor baffle leakage, can be detected by 2-D Doppler echocardiography.
