Abstract

Background: Management of adult congenital heart disease (ACHD) patients requires understanding of its complex morphology and functional features. An innovative imaging technique has been developed to display a virtual multi-planar reconstruction obtained from contrast-enhanced multidetector-computed tomography (MDCT) corresponding to the same cross-sectional image from transthoracic echocardiography (TTE). The aim of this study is to assess the usefulness of this imaging technology in ACHD patients. Methods: This study consisted of 46 consecutive patients (30 women; mean age, 52 ± 18 years old) with ACHD who had undergone contrast MDCT. All patients underwent TTE within a week of MDCT. An experienced sonographer who did not know the results of MDCT conducted a diagnosis using TTE and, then, using the new imaging technology. We studied whether this imaging technology provided additional or unexpected findings or makes more accurate diagnosis. Results: In this imaging technology, MDCT cross-section provides higher-resolution image to the deep compared to corresponding TTE image. Depending on the MDCT section which can be arbitrarily set under the echo guide, we can diagnose unexpected or incremental lesions or more accurately assess the severity of the lesion in 27 patients (59%) compared to TTE study alone. This imaging technology was useful in the following situations: 1. For anatomical guidance for Doppler flow assessment.2. Assessment of morphology of obstruction in outflow tracts or conduit.3. To clarify the etiology of unordinary severe valvular disease.4. Assessment of the patient with diseased prosthetic valves.Conclusions: This integrated imaging technology provides incremental role over TTE in complex anatomy, and allows functional information in ACHD patients.
