Abstract
OBJECTIVES This study aimed to investigate predictive factors for revision surgery in otosclerosis. METHODS This was a retrospective, multicentre study in four tertiary centres. The primary objective was to investigate factors that were predictive of the need for revision stapes surgery. RESULTS The 'revision' group included 145 patients, and the 'control' group included 143 patients. This study identified statistically significant predictive factors for the need for revision surgery: younger age, active smoking status, dyslipidaemia and high blood pressure. There was no statistically significant difference between the two groups in terms of surgical technique or stapedotomy technique. CONCLUSION This study showed that patients who are candidates for primary stapes surgery with younger age, active smoking status, dyslipidaemia and high blood pressure are at higher risk of needing revision surgery. A holistic approach prior to stapes surgery with multidisciplinary assessment is recommended. These results are important for better patient counselling on expected outcomes and risks.

Abstract
PURPOSE To evaluate the potential of non-contrast myocardial T1 mapping on cardiovascular magnetic resonance examination (CMR) in differentiating patients with Fabry disease (FD) from those with hypertrophic cardiomyopathy (HCM) and healthy control subjects. MATERIALS AND METHODS Seventeen patients with FD (8 men, 9 women; mean age, 48 ±18 [SD] years; [range: 19-73 years]; 53% with left ventricular hypertrophy [LVH]) were matched with 36 patients with hypertrophic cardiomyopathy (HCM) (22 men, 14 women; mean age, 57±16 [SD] years; [range: 22-85 years]) and 70 healthy control subjects (34 men, 36 women; mean age, 38 ±15 [SD] years; [range: 18-65 years]). Cardiac T1 mapping was performed using the modified Look-Locker inversion (MOLLI®) sequence on a 1.5-T magnet. T1 values were calculated, on midventricular section, for septal left ventricular segments (S8-S9) and all mid-ventricular ones (global T1 values; S7-S12). Statistical analysis included unpaired Mann-Whitney test, receiver operating characteristic curve and likelihood ratios. RESULTS Septal native T1 values were significantly decreased in patients with FD (889±61 [SD] ms; range: 784-980ms) compared to those with HCM (995±48 [SD] ms; range: 935-1125ms) (P<0.001) and versus healthy controls (965±29 [SD] ms; range: 910-1028ms) (P<0.001). Global native T1 values were also significantly decreased in patients with FD (891±49 [SD] ms; range 794-970ms) compared to those with HCM (995±34 [SD] ms; range: 952-1086ms) (P<0.001) and versus healthy controls (966±27 [SD] ms; range: 920-1042ms) (P<0.001). A septal left ventricular native T1 cutoff value of 940ms could distinguish FD from HCM with 88% sensitivity (95% CI: 73-100%) and 92% specificity (95% CI: 83-100%). Positive likelihood ratio was 11, negative likelihood ratio was 0.12. Compared to controls, the same threshold could distinguish FD with 88% sensitivity (95% CI: 73-100%) and 86% specificity (95% CI: 78-94%). Positive likelihood ratio was 6.3, negative likelihood ratio was 0.14. T1 value was abnormal in 4 of 8 (50%) of FD patients who did not have LVH. CONCLUSION Native T1 values are significantly lower in patients with FD by comparison with those with HCM and healthy volunteers.

Abstract
PURPOSE The purpose of this study was to quantify the distribution of trabeculated (T) and compact (C) left ventricular (LV) myocardium masses in a healthy Caucasian population against age, gender and LV parameters, and to provide normal values for T, C and T/C. MATERIALS AND METHODS One hundred and forty healthy subjects were prospectively recruited and underwent cardiac MRI at 1.5T with a stack of short-axis cine sequences covering the entire LV. End-diastolic volume (EDV), C and T masses were quantified using a semi-automatic method. Ejection fraction (EF) and T/C ratio were computed. RESULTS We included 70 men and 70 women with a mean age of 44±14 (SD) years (range: 20-69 years). The mean EF was 63.7±6.3 (SD) % (range: 50.7-82.0%), the mean EDV was 75.9±16.2 (SD) mL/m2 (range: 36.4-112.2mL/m2), the mean C mass was 53.9±11.2 (SD) g/m2 (range: 26.5-93.4g/m2) and the mean T mass was 4.9±2.4 (SD) g/m2 (range: 1.1-11.4g/m2). The T/C ratio was 9.2±4.5% (range: 2.0-29.4%). Multivariate ANOVA test showed that the compact mass was influenced by EDV (P<0.0001), EF (P=0.001) and gender (P<0.0001), and the trabeculated mass depended on EDV (P<0.0001), gender (P=0.002) and age (P<0.0001), while the T/C ratio was only influenced by age (P=0.0003). Spearman test showed a correlation between EDV and C (r=0.60; P<0.0001),T (r=0.46; P<0.0001) and T/C ratio (r=0.26; P=0.0023).T and T/C ratio correlated with EF (r=-0.18, P=0.0373; r=-0.18, P=0.0321, respectively). CONCLUSION While the compact and trabeculated myocardium masses appear to relate separately to the cardiac function, age and gender, their ratio T/C appears to only decrease with age. Furthermore, we propose here normal values for T, C and T/C in a cohort of healthy Caucasians subjects.
