Evaluation of intracardiac shunts with cardiac magnetic resonance

  • Patrick M. Colletti


Intracardiac shunts including atrial septal defect, ventricular septal defect, endocardial cushion defects, and surgical baffles may be identified, localized, and quantified using cardiac MRI methods. Both dark-blood and bright-blood techniques are helpful to identify anatomy. Contrast enhancement is especially useful for identifying associated vascular anomalies. Dynamic first-pass contrast agent signal-time studies may demonstrate rapid recirculation and shunting. Volumetric and phase contrast cine methods are useful to quantify flow. Pulmonary to systemic (Qp/Qs) flow ratios may be calculated noninvasively by comparing the pulmonary artery flow to the aortic flow measurement.

PC-cine flow measurements in the aorta and pulmonary artery are more accurate than biventricular cine MRI for the assessment of Qp/Qs ratios. Qp and Qs combined with biventricular cine CMR enables the quantification of hemodynamic significant shunts, higher-grade valvular regurgitation, and biventricular global systolic function with a single examination.PubMedCrossRefGoogle Scholar

VENC PC-cine flow MR-quantified stroke flow in the aorta and main pulmonary artery and the Qp/Qs were calculated and compared with oximetric data derived from cardiac catheterization and from CMR volumetric data. VENC PC-cine flow MR is an accurate and reproducible method for measuring Qp/Qs in left to right shunts. Because it is completely noninvasive, it can be used to monitor shunt volume over time.PubMedCrossRefGoogle Scholar

In comparison to oximetry and indocyanine green, VENC PC-cine flow MR correctly identified 12 patients with a Qp/Qs of less than 1.5 (nine without intracardiac shunting and three with small shunts) and nine patients with a Qp/Qs of at least 1.5 (six with ASD, one with VSD, one with PDA, and one with both ASD and PDA).PubMedGoogle Scholar

PC-cine flow MR quantitation uses the phase of the MR signal to reconstruct images at frequent intervals throughout the cardiac cycle. From this, 2D flow maps, velocity, and volume flow data can be obtained. MR velocity mapping may be of considerable value when Doppler echocardiography results are unsatisfactory or equivocal.PubMedCrossRefGoogle Scholar

Qp/Qs ratios were calculated from both cine MR stroke volume data and PC-cine flow MR velocity-mapping flow data in seven patients with ASD. Measurements of LV and RV stroke corresponded closely with those of aortic (r = 0.98) and pulmonary flow (r = 0.99) respectively, and Qp/Qs flow ratios agreed with stroke volume ratios (r = 0.92).PubMedCrossRefGoogle Scholar

In 10 patients with shunt defects (six ASD/three VSD/one PDA), CMR gave a Qp/Qs ratio of 2.09 ± 0.67. Calculated shunt sizes were 47.05% ± 17.45%.

Because septal thinning adjacent to a secundum ASD may appear to be part of the defect, CMR measurements overestimated major diameter and area of secundum ASDs by 48% and 125%, respectively. PC-cine flow MR images acquired in the plane of an ASD defined the defect size and shape with sufficient accuracy to permit stratification of patients to closure of the defect by catheter-based techniques versus surgery.PubMedGoogle Scholar

Heart 1997, 78:382–389. In 34 adult patients, maximum secundum ASD dimensions were measured and compared with surgery. Doppler myocardial imaging was a more effective technique than standard grey scale echocardiography in describing morphology. This correlated well with gated VENC PC-cine flow MR (maximum velocity sensitivity of 120 cm/sec) with the imaging plane parallel to, and contiguous with, the right atrial side of the interatrial septum, to provide an en face view of the defect.PubMedGoogle Scholar

Blood flow through a secundum atrial septal defect as assessed PC-cine flow MR (n = 24) overestimated the shunt compared difference between pulmonary and aortic flows. The mean between three repeated PC-cine flow MR measurements in location was 5.3% (SD ± 4.0%, n = 522), demonstrating good Interobserver variability was low.
