Description
Summary:A 59-year-old asymptomatic male was referred to our hospital for evaluation 44 years after surgical correction of a Fallot’s tetralogy. Transthoracic echocardiography showed a good surgical result with only a mild subvalvular pulmonary stenosis and mild pulmonary regurgitation. However, in the parasternal short axis a diastolic colour Doppler flow was seen in the right ventricular outflow tract with a maximum velocity over 4 m/s (figure 1). Pulmonary regurgitation seemed very unlikely because of the high velocity in the absence of elevated pulmonary artery pressure. Because a fistula was suspected, a multislice computer tomography scan was performed.
