The validation of a new comprehensive headache-specific quality of life questionnaire
BACKGROUND: Measuring quality of life (QOL) is an important means of assessing the impact of headache. The currently used QOL questionnaires are usually geared toward migraine and focus on a limited number of factors, thus they are not necessarily informative in other headache types. We report the psychometric properties of a new questionnaire, the Comprehensive Headache-related Quality of life Questionnaire (CHQQ) that may be more sensitive to the burden of headache. PATIENTS AND METHODS: A total of 202 patients suffering from migraine (n = 168) or tension-type headache (TTH) (n = 34) completed the CHQQ and SF-36, a generic QOL questionnaire. We assessed the reliability and validity of the CHQQ and its physical, mental and social dimensions. RESULTS: The questionnaire was easy to administer. Reliability was excellent with Cronbach's alpha being 0.913 for the whole instrument (0.814-0.832 for its dimensions). The dimensions and total score showed significant correlations with the patients' headache characteristics (criterion validity), and were also significantly correlated with the SF-36 domains (convergent validity). The total score and dimensions were significantly (p < 0.005) lower in the migraine group than in the TTH group (discriminative validity). CONCLUSION: In this study the new headache-specific QOL instrument showed adequate psychometric properties
Reliability, construct and criterion validity of the KIDSCREEN-10 score: a short measure for children and adolescents’ well-being and health-related quality of life
Background
To assess the criterion and construct validity of the KIDSCREEN-10 well-being and health-related quality of life (HRQoL) score, a short version of the KIDSCREEN-52 and KIDSCREEN-27 instruments.
Methods
The child self-report and parent report versions of the KIDSCREEN-10 were tested in a sample of 22,830 European children and adolescents aged 8–18 and their parents (n = 16,237). Correlation with the KIDSCREEN-52 and associations with other generic HRQoL measures, physical and mental health, and socioeconomic status were examined. Score differences by age, gender, and country were investigated.
Results
Correlations between the 10-item KIDSCREEN score and KIDSCREEN-52 scales ranged from r = 0.24 to 0.72 (r = 0.27–0.72) for the self-report version (proxy-report version). Coefficients below r = 0.5 were observed for the KIDSCREEN-52 dimensions Financial Resources and Being Bullied only. Cronbach alpha was 0.82 (0.78), test–retest reliability was ICC = 0.70 (0.67) for the self- (proxy-)report version. Correlations between other children self-completed HRQoL questionnaires and KIDSCREEN-10 ranged from r = 0.43 to r = 0.63 for the KIDSCREEN children self-report and r = 0.22–0.40 for the KIDSCREEN parent proxy report. Known group differences in HRQoL between physically/mentally healthy and ill children were observed in the KIDSCREEN-10 self and proxy scores. Associations with self-reported psychosomatic complaints were r = −0.52 (−0.36) for the KIDSCREEN-10 self-report (proxy-report). Statistically significant differences in KIDSCREEN-10 self and proxy scores were found by socioeconomic status, age, and gender.
Conclusions
Our results indicate that the KIDSCREEN-10 provides a valid measure of a general HRQoL factor in children and adolescents, but the instrument does not represent well most of the single dimensions of the original KIDSCREEN-52. Test–retest reliability was slightly below a priori defined thresholds
In vivo MRI and ex vivo histological assessment of the cardioprotection induced by ischemic preconditioning, postconditioning and remote conditioning in a closed-chest porcine model of reperfused acute myocardial infarction: importance of microvasculature
BACKGROUND: Cardioprotective value of ischemic post- (IPostC), remote (RIC) conditioning in acute myocardial infarction (AMI) is unclear in clinical trials. To evaluate cardioprotection, most translational animal studies and clinical trials utilize necrotic tissue referred to the area at risk (AAR) by magnetic resonance imaging (MRI). However, determination of AAR by MRI' may not be accurate, since MRI-indices of microvascular damage, i.e., myocardial edema and microvascular obstruction (MVO), may be affected by cardioprotection independently from myocardial necrosis. Therefore, we assessed the effect of IPostC, RIC conditioning and ischemic preconditioning (IPreC; positive control) on myocardial necrosis, edema and MVO in a clinically relevant, closed-chest pig model of AMI. METHODS AND RESULTS: Acute myocardial infarction was induced by a 90-min balloon occlusion of the left anterior descending coronary artery (LAD) in domestic juvenile female pigs. IPostC (6 x 30 s ischemia/reperfusion after 90-min occlusion) and RIC (4 x 5 min hind limb ischemia/reperfusion during 90-min LAD occlusion) did not reduce myocardial necrosis as assessed by late gadolinium enhancement 3 days after reperfusion and by ex vivo triphenyltetrazolium chloride staining 3 h after reperfusion, however, the positive control, IPreC (3 x 5 min ischemia/reperfusion before 90-min LAD occlusion) did. IPostC and RIC attenuated myocardial edema as measured by cardiac T2-weighted MRI 3 days after reperfusion, however, AAR measured by Evans blue staining was not different among groups, which confirms that myocardial edema is not a measure of AAR, IPostC and IPreC but not RIC decreased MVO. CONCLUSION: We conclude that IPostC and RIC interventions may protect the coronary microvasculature even without reducing myocardial necrosis

The rate of sudden cardiac death in mitral valve prolapse (MVP) patients is roughly twice that observed in the general population. Arrhythmogenic bileaflet MVP syndrome has been recently described and mitral annulus disjunction (MAD) has been found associated with papillary muscle fibrosis and ventricular arrhythmias even without severe mitral regurgitation. An underlying primary structural myocardial disease might be expected and the non-invasive imaging techniques are playing an increasingly important role in the detection of myocardial fibrosis as a focal arrhythmogenic substrate. Standard 2D-, 3D- and speckle tracking echocardiography and cardiac MRI can help to differentiate between the benign and malignant forms of MVP.
A 52-year-old man with a history of hypertension was referred for evaluation of frequent palpitations and presyncope. Ambulatory Holter monitoring showed paroxysmal atrial fibrillation and non-sustained ventricular tachycardias. Dilated left ventricle (LVEDD: 65mm, LVESD: 45 mm) and left atrium (LAVi: 52mL/m2), moderately reduced left ventricular (LV) systolic function (LVEF: 42%), and reduced LV global longitudinal strain (GLS: -13.5%) with severely decreased segmental longitudinal strain in the basal inferolateral segment were measured by transthoracic echocardiography. The diastolic function was preserved, however Pickelhaube sign was noticed in the lateral mitral annulus TDI curves. MAD (17 mm) and curling motion of the inferolateral basal segment of the left ventricle was observed. Transesophageal echocardiography showed bileaflet mitral valve prolapse with the involvement of all the six scallops (mitral valve prolapse volume: 10.2 mL). Severe mitral regurgitation (3D vena contracta area: 1cm2) and extremely dilated and dyskinetic mitral annulus (diameters: 55x72x12 mm, area: 34 cm2) was measured by 3D echocardiography. MRI showed transmural late gadolinium enhancement in the underlying myocardium of both papillary muscles and midmyocardial enhancement in the basal inferior, inferolateral and anteroseptal LV segments. During electrophysiology study ventricular fibrillation was easily induced and ICD was placed for primary prevention of sudden cardiac death. The patient was referred to the heart surgeon for mitral valve replacement.
This case highlights the importance of early recognition of MAD and arrhythmogenic MVP syndrome using novel non-invasive imaging techniques. The presence of MAD, the curling motion of the inferolateral basal LV segment, the Pickelhaube sign, the decreased LVEF and GLS, the characteristic segmental longitudinal strain pattern and the presence of late enhancement in the papillary muscles and the surrounding myocardium could be warning signs of the malignant form of MVP.

Introduction
Bland-White-Garland syndrome or ALCAPA (anomalous left coronary artery from pulmonary artery) syndrome is a rare congenital disorder with a prevalence of 1: 300,000. This condition is one the most common causes of infant myocardial infarction. It can ultimately lead to heart failure before the age of one, however when pronounced left and right coronary artery collateralization is present, patients may remain asymptomatic until older age. Due to the development and availability of non-invasive imaging techniques, these patients diagnosed more frequently in recent years.
Case description: We present a 53-year-old patient with treated hypertension and five uncomplicated pregnancies. At the age of 40, the patient was referred to coronary angiography due to her dyspnea on exertion. The examination showed that the left main coronary artery (LMCA) originates from the pulmonary artery 7 mm above the pulmonary valve and the right coronary artery is significantly dilated. Based on the mild complaints and good left ventricle systolic function, conservative therapy was recommended by the cardiac surgery team. Since 2018 the patient has had gradually worsening complaints despite of the therapy adjusted for chronic heart failure. Q-waves were depicted on the 12-lead ECG in aVL and V1-V6 leads. Echocardiography showed dilated left ventricle (LV), LV hypertrophy, diffuse hypokinesia, decreased LV systolic function and diastolic dysfunction. At our clinic, we performed cardiac magnetic resonance imaging (CMR) which showed moderately reduced LV ejection fraction, diffuse LV hypokinesia, increased LV volume, septal LV hypertrophy. We visualized the retrograde flow on the LMCA, the shunt volume at the anomalous artery was 1,27 L/min. The CMR also showed irreversible damage of the subendocardial region of the myocardium via late gadolinium enhancement in the area supplied by the LMCA. Since we planned to reevaluate the surgical possibilities, the collateral network with tortuous and dilated left and right coronary arteries were visualized by coronary CT angiography. The surgical team at our institute decided to perform myocardial revascularization and restoration of dual coronary artery supply.
Discussion
ALCAPA is usually diagnosed in infancy however, in about 10-15% of cases the disease is only recognized in adulthood. The long-term morphological and functional characteristics of the syndrome may include reversible/irreversible ischemic damage, systolic and diastolic dysfunction, mitral regurgitation, significant collateral circulation, left-to-right shunt, dilated coronary arteries. Surgical myocardial revascularization and restoration of dual coronary artery supply is recommended even in adult patients.

P876Cardiac magnetic resonance based feature-tracking myocardial strain analysis in MINOCA patients
Abstract
The diagnostic performance of cardiac magnetic resonance (CMR) based deformation imaging (feature tracking - FT) has been demonstrated in various groups of patients including acute myocardial infarction and acute myocarditis. However, the capability of this method to distinguish between patients with the working diagnosis of MINOCA is yet to be tested.
We aimed to compare standard CMR parameters and investigate the differential diagnostic value of CMR-FT myocardial strain in pts with the working diagnosis of MINOCA.
From our consecutive register of pts with troponin positive acute coronary syndrome (n=234 pts) we enrolled 100 pts (47.7±14 y; 51 male) in this study.Twenty-five pts were selected randomly from each group of acute myocardial infarction (MI), acute myocarditis, Tako-Tsubo cardiomyopathy (TTC) and pts without structural alteration on CMR, and an additional group of healthy control (n=20, 46±8.2 y; 12 male). Standard CMR parameters such as left ventricular ejection fraction (LVEF), end-diastolic (LVEDVi) and end-systolic (LVESVi) volumes, myocardial mass were assessed and compared between the groups. We performed CMR-FT analysis of the left ventricle, including: global longitudinal (GLS), circumferential (GCS), standard deviation (SD) of the peak circumferential (CS) strain furthermore mechanical dispersion (MD), defined as the SD of the time-to-peak circumferential (MDC) strain of the LV segments expressed as percent of the cardiac cycle.
LVEF was lower (44±9.1%) and LVESVi (52.5±12.9ml/m2) was higher in TTC pts compared to all other groups (p<0.001). The LVEF, LVEDVi and LVESVi parameters did not show significant difference between MI and myocarditis pts (LVEF 56.5±7% vs 55±6.6%; LVEDVi 85.4±14.8 vs 92.7±10.7ml/m2; LVESVi 37.7±11.4 vs 41.5±9.1ml/m2). GLS and GRS were significantly reduced in TTC pts (−11.4±4.8%; 43.09±12.5%) compared to all other groups (p<0.001). GCS was impaired in pts with TTC, acute myocarditis and MI compared to healthy controls (−14±3.7 vs −18.7±3.7 vs −19.1±3.8 vs −23.2±3.1%, p<0.001), however there was no significant difference between myocarditis and MI pts. SD of the peak CS was lower in myocarditis compared to other groups (p<0.001). MDC was elevated in TTC and MI compared to myocarditis and healthy controls (16.3±5 vs 13.3±3.4 vs 8.1±3.3 vs 9.46±3.5% p<0.05). There was no significant difference between healthy controls and patients without structural alterations in any strain parameter.
Strain analysis of a TTC patient
Feature tracking analysis may enable differentiation between patients with MINOCA. TTC reduces global myocardial strain of the left ventricle and causes regional heterogeneity of the left ventricular contraction. Although standard volumetric CMR parameters and CMR based global strain values have limited capability to distinguish between MI and myocarditis with preserved ejection fraction, regional heterogeneity, expressible in MDC is significantly elevated in MI compared to myocarditis and healthy controls.
