Abstract

Background: In congenital heart disease (CHD) patients, detailed three-dimensional anatomy depiction plays a pivotal role for diagnosis and therapeutical decision making. Hence, the present study investigated the applicability of an advanced cardiovascular magnetic resonance (CMR) whole heart imaging approach utilizing nonselective excitation and compressed sensing for anatomical assessment and interventional guidance of CHD patients in comparison to conventional dynamic CMR angiography. Methods: 86 consecutive pediatric patients and adults with congenital heart disease (age, 1 to 74 years; mean, 35 years) underwent CMR imaging including a free-breathing, ECG-triggered 3D nonselective SSFP whole heart acquisition using compressed SENSE (nsWHcs). Anatomical assessability and signal intensity ratio (SIR) measurements were compared with conventional dynamic 3D-/4D-MR angiography. Results: The most frequent diagnoses were partial anomalous pulmonary venous drainage (17/86, 20%), transposition of the great arteries (15/86, 17%), tetralogy of Fallot (12/86, 14%), and a single ventricle (7/86, 8%). Image quality of nsWHcs was rated as excellent/good in 98% of patients. nsWHcs resulted in a reliable depiction of all large thoracic vessels (anatomic assessability, 99%–100%) and the proximal segments of coronary arteries and coronary sinus (>90%). nsWHcs achieved a homogenously distributed SIR in all cardiac cavities and thoracic vessels without a significant difference between pulmonary and systemic circulation (10.9 ± 3.5 and 10.6 ± 3.4; p = 0.15), while 3D angiography showed significantly increased SIR for targeted vs. non-targeted circulation (PA-angiography, 15.2 ± 8.1 vs. 5.8 ± 3.6, p < 0.001; PV-angiography, 7.0 ± 3.9 vs. 17.3 ± 6.8, p < 0.001). Conclusions: The proposed nsWHcs imaging approach provided a consistently high image quality and a homogeneous signal intensity distribution within the pulmonary and systemic circulation in pediatric patients and adults with a wide spectrum of congenital heart diseases. nsWHcs enabled detailed anatomical assessment and three-dimensional reconstruction of all cardiac cavities and large thoracic vessels and can be regarded particularly useful for preprocedural planning and interventional guidance in CHD patients.
