With the capability of accurate and comprehensive assessment of cardiac morphology and function, cardiac magnetic resonance (MR) imaging plays an important role in the diagnosis of a range of heart diseases [1]. The conventional balanced steady state free precession (bSSFP) cine sequence with breath-holding (BH) is a clinical reference standard for assessing ventricular volumes and function in cardiac MR [2]. However, this approach requires multiple BHs to complete a full scan and to avoid respi…
