Abstract:
Two infants with tetralogy of Fallot with absent pulmonary valve were studied with electrocardiographically gated magnetic resonance imaging using a 1.5 T imaging system. In each case, imaging was performed successfully. The magnetic resonance imaging clearly demonstrated a rudimentary pulmonary valve, an aneurysmal pulmonary artery, and compression of the mainstem bronchi. Cine MRI revealed phasic compression of the bronchi by an aneurysmally dilated pulmonary artery. Magnetic resonance imaging produced high quality images and provided all of the anatomic information required for preoperative evaluation.
