[Evaluation of congenital heart disease in adults].
Improvements in the diagnosis and surgical treatment of congenital heart disease during infancy and childhood have resulted in an outstanding increase in the prevalence of these entities during adulthood. Congenital heart disease in the adult represents a new diagnostic challenge to the consultant cardiologist, unfamiliar with the anatomical and functional complexities of cardiac malformations. Assessment of adult congenital heart disease with imaging techniques can be as accurate as in children. However, these techniques cannot substitute for a detailed clinical assessment. Physical examination, electrocardiography and chest x-rays remain the three main pillars of bedside diagnosis. Transthoracic echocardiography is undoubtedly the imaging technique which provides most information, and in many situations no additional studies are needed. Nevertheless, ultrasound imaging properties in adults are not as favorable as in children, and prior surgical procedures further impair image quality. Despite recent advances in ultrasound technologies such as harmonic or contrast imaging, other diagnostic procedures are sometimes required. Fortunately, transesophageal echocardiography and magnetic resonance imaging are easily performed in the adult, and do not require anaesthetic support, in contrast to pediatric patients. These techniques, together with nuclear cardiology and cardiac catheterization, complete the second tier of diagnostic techniques for congenital heart disease. To avoid unnecessary repetition of diagnostic procedures, the attending cardiologist should choose the sequence of diagnostic techniques carefully; although the information this yields is often redundant, it is also frequently complementary. This article aims to compare the diagnostic utility of different imaging techniques in adult patients with congenital heart disease, both with and without prior surgical repair.
