“…Echocardiography can be challenging because of limitations related to the acoustic window, which is affected by the post-surgical retrosternal location of the pulmonary trunk and pulmonary arteries [12]. MRI using standard axial double inversion recovery or multiplanar T2-HASTE sequences such as black blood contrast or steady-state free precession (SSFP) as bright blood sequences is therefore superior and is now the method of choice for depicting the geometry of the cardiovascular system in TGA patients after surgery [13–16]. Pulmonary blood-flow can be evaluated with cine phase contrast (PC) MRI to investigate pulmonary stenoses arising from the altered vessel geometry and morphological vessel lumen changes during the heart cycle [12].…”

Objectives To characterise aortic and pulmonary haemodynamics and investigate the correlation with post-surgical anatomy in patients with dextro-transposition of the great arteries (d-TGA). Methods Four-dimensional (4D) MRI was performed in 17 patients after switch repair of TGA and 12 healthy controls (age, 11.9±5.4 vs 23.3±1.6 years). Patients were divided according to the pulmonary trunk (TP) position in relation to the ascending aorta (AAo): anterior (n =10) and right/left anterior position (n =7). Analysis included visual grading (ranking 0–2) of pulmonary and aortic vortical and helical flow, flow velocity quantification, blood-flow distribution to the right and left pulmonary arteries (flow ratio rPA:lPA), and vessel lumen areas. Results Anterior TP position was associated with increased vortices in six out of ten patients compared with right anterior TP position (one out of seven) and controls (none). Reduced systolic lPA and TP lumina in patients resulted in significantly increased peak systolic velocities (P <0.001). Flow ratio rPA:lPA was more heterogeneous in patients (rPA:lPA=1.56 ±0.78 vs volunteers 1.09±0.15; P <0.05) with predominant flow to the rPA. Eleven patients presented increased helices in the AAo (grade 1.6). Conclusions Evaluation of post-surgical haemodynamics in TGA patients revealed increased vortical flow for anterior TP position, asymmetric flow and increased systolic flow velocity in the pulmonary arteries owing to reduced vascular lumina.

“…Accordingly, studies have shown that detection of branch pulmonary artery stenosis in ASO patients by CMR is accurate and superior to the information obtained by echocardiography. [99][100][101][102][103] Moreover, if the echocardiographic assessment of ventricular parameters or the severity of valve regurgitation is in question, CMR can resolve this uncertainty with reliable quantitative data. Serial CMR evaluations can then be compared to assess for disease progression.…”

“…The postoperative status of the great vessels has been adequately assessed with SE MRI ( Figure 13) [10,45,64]. Stenoses, particularly in the pulmonary artery branches, were clearly better detected with SE MRI than with echocardiography [13]. Very likely, several MRI studies will address the follow-up of the arterial switch procedure in the near future.…”

With the increasing number of patients surviving after therapeutic intervention for congenital heart disease (CHD), accurate and frequent follow-up of their morphologic and functional cardiovascular status is required, preferably with a noninvasive imaging technique. Echocardiography, either transthoracic or transesophageal, has been the first choice for this purpose, and will probably keep that status, at least in a large segment of the CHD spectrum. Magnetic resonance imaging (MRI) is an established method for high-resolution visualization of cardiovascular morphology. In the past decade, newer MRI techniques have been developed that allow functional evaluation of CHD patients. Particularly the introduction of breath-hold imaging, contrast-enhanced MRA and user-friendly computer software for image analysis may move functional MRI of CHD from the science laboratory to clinical use. It is already evident that MRI is superior to echocardiography in certain areas of limited echocardiographic access, such as the pulmonary artery branches and the aortic arch in adult patients. But MRI has also a unique potential for accurate volumetric analysis of ventricular function and cardiovascular blood flow, without any geometric assumptions. If supported by increased cooperation between cardiologists and radiologists, MRI will grow into a useful noninvasive imaging tool that, together with echocardiography, will obviate the need for invasive catheter studies for diagnostic purposes.
