Cardiac MRI is currently the standard imaging modality for patients with congenital heart disease (CHD). However, the requirement for breath holds remains a big challenge in clinical practice and image quality is often significantly degraded by respiratory motion artifacts. We employed respiratory-triggered pseudo-golden-angle bSSFP imaging for free-breathing cine MRI and compared cardiac volumetry, function, and image quality with the standard breath hold technique. The proposed method showed good agreement with comparable diagnostic image quality and advantage in patients with limited breath hold capability. These demonstrated promise for a wider clinical routine application in patients with CHD.
