ABSTRACT

Absence of myocardial fibrosis on late gadolinium enhanced (LGE) magnetic resonance imaging (MRI) is associated with improvement of left ventricular systolic function after catheter ablation (CA) for atrial fibrillation (AF) with non-ischemic dilated cardiomyopathy (NIDCM). Extracellular volume fraction (ECV) by T1 mapping has emerges as a non-invasive mean to quantify severity of myocardial fibrosis. The aim of this study was to assess the incremental value of ECV over LGE-MRI for the improvement of LVEF(∆EF) after CA in NIDCM patients. A total of thirty-two patients with NIDCM and AF (mean age 67.4 ± 9.3 years; 29 (91%) male) were retrospectively studied. Using a 1.5 T MR scanner and 32 channel cardiac coils, LGE-MRI, pre- and post-T1 mapping images of LV wall at mid-ventricular level (modified look-locker inversion recovery sequence) were acquired. All patients successfully underwent CA for AF, and the improvement of LVEF after CA were evaluated by echocardiography. All patients restored sinus rhythm after CA at the time of echocardiography. The mean LVEF was 35.1 ± 9.7% before CA and 52.2 ± 10.2% after CA (p < 0.001), resulting an increase of 17.4 ± 12.6%. Significant correlation was found between ∆LVEF and % LGE (r = − 0.49, p = 0.004), ∆LVEF and extracellular volume fraction (ECV) (r = − 0.47, p = 0.010). Area under the receiver operating characteristics curve (AUC) of combination of %LGE and ECV for predicting improvement of LVEF > 10% was substantially higher than that of %LGE alone (AUC: 0.830 vs 0.602). In NIDCM patients with AF, ECV had incremental value over %LGE for predicting improvement of EF by CA, suggesting that the assessment of diffuse interstitial fibrosis may be important to forecast the response of CA.

All patients successfully underwent CA for AF, and the improvement of LVEF after CA were evaluated by echocardiography. All patients restored sinus rhythm after CA at the time of echocardiography. The mean LVEF was 35.1\u2009\u00b1\u20099.7% before CA and 52.2\u2009\u00b1\u200910.2% after CA (p\u2009<\u20090.001), resulting an increase of 17.4\u2009\u00b1\u200912.6%. Significant correlation was found between \u2206LVEF and % LGE (r\u2009=\u2009\u2212 0.49, p\u2009=\u20090.004), \u2206LVEF and extracellular volume fraction (ECV) (r\u2009=\u2009\u2212 0.47, p\u2009=\u20090.010). Area under the receiver operating characteristics curve (AUC) of combination of %LGE and ECV for predicting improvement of LVEF\u2009>\u200910% was substantially higher than that of %LGE alone (AUC: 0.830 vs 0.602). In NIDCM patients with AF, ECV had incremental value over %LGE for predicting improvement of EF by CA, suggesting that the assessment of diffuse interstitial fibrosis may be important to forecast the response of CA.",

24 schema:description Absence of myocardial fibrosis on late gadolinium enhanced (LGE) magnetic resonance imaging (MRI) is associated with improvement of left ventricular systolic function after catheter ablation (CA) for atrial fibrillation (AF) with non-ischemic dilated cardiomyopathy (NIDCM). Extracellular volume fraction (ECV) by T1 mapping has emerges as a non-invasive mean to quantify severity of myocardial fibrosis. The aim of this study was to assess the incremental value of ECV over LGE-MRI for the improvement of LVEF(∆EF) after CA in NIDCM patients. A total of thirty-two patients with NIDCM and AF (mean age 67.4 ± 9.3 years; 29 (91%) male) were retrospectively studied. Using a 1.5 T MR scanner and 32 channel cardiac coils, LGE-MRI, pre- and post-T1 mapping images of LV wall at mid-ventricular level (modified look-locker inversion recovery sequence) were acquired. All patients successfully underwent CA for AF, and the improvement of LVEF after CA were evaluated by echocardiography. All patients restored sinus rhythm after CA at the time of echocardiography. The mean LVEF was 35.1 ± 9.7% before CA and 52.2 ± 10.2% after CA (p < 0.001), resulting an increase of 17.4 ± 12.6%. Significant correlation was found between ∆LVEF and % LGE (r = − 0.49, p = 0.004), ∆LVEF and extracellular volume fraction (ECV) (r = − 0.47, p = 0.010). Area under the receiver operating characteristics curve (AUC) of combination of %LGE and ECV for predicting improvement of LVEF > 10% was substantially higher than that of %LGE alone (AUC: 0.830 vs 0.602). In NIDCM patients with AF, ECV had incremental value over %LGE for predicting improvement of EF by CA, suggesting that the assessment of diffuse interstitial fibrosis may be important to forecast the response of CA.
