Abstract

The purpose of this article is to illustrate the usefulness of MR imaging in the clinical evaluation of congenital and acquired cardiac diseases characterised by ventricular septal wall motion abnormality. Recognition of the features of abnormal ventricular septal motion in MR images is important to evaluate the haemodynamic status in patients with congenital and acquired heart diseases in routine clinical practice.
Zusatzmaterial
Movie 1 A 42-year-old woman with pulmonary regurgitation after surgically repaired tetralogy of Fallot who presented with dyspnea at exertion. Short-axis steady-state free precession cine MR images showing flattening of the ventricular septum at early diastole with sparing of left ventricular deformation during systole (MOV 4,840 kb)

Movie 2 An 18-year-old man with severe idiopathic pulmonary hypertension presented with haemoptysis. Short-axis steady-state free precession cine MR images show thickened right ventricular wall, flattened interventricular septum during diastole and septal leftwards bowing during systole. The maximum pulmonary trunk diameter was 37 mm and according to the time-flow curves obtained from velocity-encoded cine MR images (not shown), the velocity peak in the pulmonary trunk was 140 cm/s (MOV 10,869 kb)

Movie 3 A 36-year-old man who had had symptoms of right heart failure for 2 months. Short-axis steady-state free precession cine MR images obtained during operator-guided breathing inspiration shows septal flattening during early filling and restoration of the normal concave shape at the end of diastolic filling. Note also the diffusely thickened hypointense pericardium (MOV 21,266 kb)
