AbstractCardiac MR (CMR) is a standard modality for assessing ventricular function of single ventricles. CMR feature-tracking (CMR-FT) is a novel application enabling strain measurement on cine MR images and is used in patients with congenital heart diseases. We sought to assess the feasibility of CMR-FT in Fontan patients and analyze the correlation between CMR-FT strain values and conventional CMR volumetric parameters, clinical findings, and biomarkers. Global circumferential (GCS) and longitudinal (GLS) strain were retrospectively measured by CMR-FT on Steady-State Free Precession cine images. Data regarding post-operative course at Fontan operation, and medication, exercise capacity, invasive hemodynamics, and blood biomarkers at a time interval ± 6 months from CMR were collected. Forty-seven patients underwent CMR 11 ± 6 years after the Fontan operation; age at CMR was 15 ± 7 years. End-diastolic volume (EDV) of the SV was 93 ± 37 ml/m2, end-systolic volume (ESV) was 46 ± 23 ml/m2, and ejection fraction (EF) was 51 ± 11%. Twenty (42%) patients had a single right ventricle (SRV). In single left ventricle (SLV), GCS was higher (p < 0.001), but GLS was lower (p = 0.04) than in SRV. GCS correlated positively with EDV (p = 0.005), ESV (p < 0.001), and EF (p ≤ 0.0001). GLS correlated positively with EF (p = 0.002), but not with ventricular volumes. Impaired GCS correlated with decreased ventricular function (p = 0.03) and atrioventricular valve regurgitation (p = 0.04) at echocardiography, direct atriopulmonary connection (p = 0.02), post-operative complications (p = 0.05), and presence of a rudimentary ventricle (p = 0.01). A reduced GCS was associated with increased NT-pro-BNP (p = 0.05). Myocardial deformation can be measured by CMR-FT in Fontan patients. SLVs have higher GCS, but lower GLS than SRVs. GCS correlates with ventricular volumes and EF, whereas GLS correlates with EF only. Myocardial deformation shows a relationship with several clinical parameters and NT-pro-BNP.

Abstract Aims To evaluate the correlation between cardiac magnetic resonance (CMR) tissue abnormalities and impairment of myocardial deformation indices in patients with definite diagnosis of arrhythmogenic cardiomyopathy (AC). Methods and results 41 AC Patients with available CMR study were enrolled. Myocardial deformation indices (i.e. global longitudinal strain -GLS-; global circumferential strain -GCS-; global radial strain -GRS-) for both ventricles were calculated using feature tracking analysis. Quantification of tissue abnormalities (i.e. late gadolinium enhancement -LGE- extension expressed as percentage of total ventricular mass) was performed. Spearman’s rho correlation was evaluated. Mean age was 44 ± 13 years and 26 (63%) patients were male. Mean left ventricular (LV) ejection fraction (EF) was 54 ± 10% and mean right ventricular (RV) EF was 49 ± 12%. Median LV LGE extension was 8.9% (1.05–21) and median RV LGE extension was 0 (0–6.92). All myocardial deformation indices were moderately associated with LGE extension (for LV 3D GLS Spearman’s Rho 0.423, P 0.016; 2D GCS Spearman’s Rho 0.388, P 0.028; 3D GCS 0.362, P 0.042; 2D GRS Spearman’s Rho −0.417, P 0.018; 3D GRS −0.396, P 0.025; for RV 2D GLS Spearman’s Rho 0.385, P 0.030; RV GCS Spearman’s Rho 0.450, P 0.010; RV GRS Spearman’s Rho −0.459, P 0.008). Conclusions All myocardial deformation indices showed a moderate association with LGE extension in a cohort of patients with definite AC. Further studies are needed to validate this observation and understand its implications.
