A Long-Term Survivor with Tetralogy of Fallot Treated Only with the Classical Blalock-Taussig Shunt

Figure 2

Transthoracic echocardiogram and cardiac magnetic resonance imaging (CMRI). (a) Parasternal long-axis view shows the ventricular septal defect (VSD) (white arrow) and overriding of the aorta. (b) Color Doppler image in the long-axis view shows two shunts through the VSD (white arrow). (c) Apical four-chamber view shows the hypertrophic right ventricle. (d) There is an RV outflow obstruction with a peak velocity of 4.9 m/s. (e) Analysis of CMRI reveals a normal RV end-diastolic volume (76 ml), reduced RV ejection fraction of 28%, and preserved left ventricular ejection fraction of 60%. (f) CMRI scan shows subvalvular pulmonary stenosis (yellow arrow).
