Assessment of increased ventricular coupling using real-time cine CMR in constrictive pericarditis. Short-axis cine CMR at onset of inspiration (a) and onset of expiration (b). Images are acquired at early ventricular filling. Septal inversion occurs at inspiration (a), with increased right-sided septal motion at expiration (b), leading to an abnormal respiratory septal shift. The horizontal dashed lines indicate the position of the left hemidiaphragm.
