Abstract

We studied 11 adult patients with dextro-transposition and 5 adult patients with levo-transposition (corrected transposition) of the great arteries with real time two-dimensional (2DTTE) and live/real time three-dimensional transthoracic echocardiography (3DTTE). All patients with dextro-transposition underwent a Mustard or Senning procedure during infancy. Incremental findings provided by 3DTTE and not delineated by 2DTTE were (a) comprehensive examination of all three leaflets of the tricuspid valve including the detection and measurement of anatomic defects in the leaflets and the assessment of systolic noncoaptation and segmental prolapse; (b) en face viewing and measurement of vena contracta areas of the valvular regurgitation jets and the assessment of regurgitant volumes; (c) en face viewing of the intra-atrial baffle and localization and measurement of baffle defects as well as the measurement of vena contractas of the baffle leaks; (d) recognition of a bicuspid pulmonary valve; and (e) the quantitative assessment of left ventricular outflow tract obstruction. 3DTTE appears to be a useful noninvasive modality which could supplement 2DTTE in the comprehensive assessment of adult patients with transposition of the great arteries.
