Abstract
Objectives: In this study, we aimed to explore the influence of right-to-left shunt (RLS) presence on the clinical features of migraine and to follow-up on the post-operative curative effect of transcatheter patent foramen ovale (PFO) closure on migraine features.Methods: A total of 103 migraine patients were divided into a mild volume RLS group, moderate volume RLS group, large volume RLS group and non-RLS group in accordance with contrast enhancement transcranial Doppler (c-TCD) findings. The Visual Analogue Scale (VAS) score, migraine frequency, migraine duration, migraine disability assessment (MIDAS) and headache impact test-6 (HIT-6) scores were compared amongst the different groups. A total of 39 patients with moderate or large RLS received transcatheter PFO closure and those patients were followed up by the same criteria.Results: The attack frequency, HIT-6 and MIDAS scores amongst the migraine patients with moderate or large RLS were significantly higher than those in patients from the mild RLS group and non-RLS group (p < .05). The transcatheter closure was successful in all patients (n = 39), and no post-operative complications were observed during the hospitalisation and follow-up period. The differences in VAS, HIT-6 and MIDAS scores as well as the headache duration were statistically significant amongst patients before and after PFO closure (p < .05).Conclusions: Moderate to large RLS significantly influenced the clinical features of migraine, and transcatheter PFO closure could significantly relieve headache symptoms in migraine patients with PFO.

Abstract
Aim Transthoracic contrast echocardiography (TTCE) is recommended for screening of pulmonary arteriovenous malformations (PAVMs) in hereditary haemorrhagic telangiectasia. Shunt quantification is used to find treatable PAVMs. So far, there has been no study investigating the reproducibility of this diagnostic test. Therefore, this study aimed to describe inter-observer and inter-injection variability of TTCE. Methods We conducted a prospective single centre study. We included all consecutive persons screened for presence of PAVMs in association with hereditary haemorrhagic telangiectasia in 2015. The videos of two contrast injections per patient were divided and reviewed by two cardiologists blinded for patient data. Pulmonary right-to-left shunts were graded using a three-grade scale. Inter-observer and inter-injection agreement was calculated with κ statistics for the presence and grade of pulmonary right-to-left shunts. Results We included 107 persons (accounting for 214 injections) (49.5% male, mean age 45.0 ± 16.6 years). A pulmonary right-to-left shunt was present in 136 (63.6%) and 131 (61.2%) injections for observer 1 and 2, respectively. Inter-injection agreement for the presence of pulmonary right-to-left shunts was 0.96 (95% confidence interval (CI) 0.9–1.0) and 0.98 (95% CI 0.94–1.00) for observer 1 and 2, respectively. Inter-injection agreement for pulmonary right-to-left shunt grade was 0.96 (95% CI 0.93–0.99) and 0.95 (95% CI 0.92–0.98) respectively. There was disagreement in right-to-left shunt grade between the contrast injections in 11 patients (10.3%). Inter-observer variability for presence and grade of the pulmonary right-to-left shunt was 0.95 (95% CI 0.91–0.99) and 0.97 (95% CI 0.95–0.99) respectively. Conclusion TTCE has an excellent inter-injection and inter-observer agreement for both the presence and grade of pulmonary right-to-left shunts.

Abstract
BACKGROUND Hereditary Hemorrhagic Telangiectasia (HHT) is an autosomal dominant disease with multi-systemic vascular dysplasia. Early diagnosis through screening is important to prevent serious complications. How best to screen children of affected parents for pulmonary arteriovenous malformations (PAVMs) is often subject to debate. Transthoracic contrast echocardiogram (TTCE) is considered optimal in screening for PAVMs in adults. Guidelines for the screening of children are not specific, reflecting the lack of scientific evidence on the best method to use. OBJECTIVE Aims of this study are (i) to evaluate our current screening method, consisting of history, physical examination, pulse oximetry, and chest radiography and (ii) to assess whether postponing more invasive screening for PAVMs until adulthood is safe. METHODS This is a prospective observational cohort study using a patient database. RESULTS Over a period of 18 years (mean follow-up 9.21 years, SD 4.72 years), 436 children from HHT families were screened consecutively. A total of 175/436 (40%) children had a diagnosis of HHT. PAVMs were detected in 39/175 (22%) children, 33/39 requiring treatment by embolotherapy. None of the screened children suffered any PAVM-associated complications with this screening method. CONCLUSION This study shows that a conservative screening method during childhood is sufficient to detect large PAVMs and protect children with HHT for PAVM-related complications. Postponing TTCE and subsequent chest CT scanning until adulthood to detect any smaller PAVMs does not appear to be associated with major risk.

Abstract
Observational studies suggest that closure of a patent foramen ovale for other indications may reduce or even eliminate migraine attacks, particularly migraine with aura. The first randomized clinical trial of patent foramen ovale (PFO) closure for prevention of migraine, the MIST trial, showed negative results. The results of the other two completed studies in this area have recently been published in the last year. PRIMA and PREMIUM were also both negative for their primary endpoints. The PREMIUM trial did show a reduction in headache days in the migraine with aura subgroup but the final results of this subset analysis have not been published. There may be an as yet undetermined subgroup of patients with migraine who would benefit from closure, but slow recruitment has been a barrier to further study. Several potentially life-threatening procedure-related adverse events occurred in the clinical trials. At this time, we recommend against offering PFO closure as a preventive treatment for migraine. Based on available observational data, patients for whom PFO closure is indicated for other reasons may see some improvement in their migraines.

Abstract
Objective Several studies have shown an increased prevalence of right-to-left shunt (RLs) in migraine patients, particularly those with aura. However, the prevalence of RLs and its relation to Japanese patients with migraine are unknown. We investigated the prevalence of RLs in Japanese patients with migraine. Methods In total, 112 consecutive patients with migraine were recruited from our headache outpatient clinic. Migraine with aura (MA) and migraine without aura (MWOA) were diagnosed according to the International Classification of Headache Disorders, 3rd edition (beta-version). Contrast transcranial Doppler ultrasound was used to detect RLs, including patent foramen ovale (PFO). Then, the associations between RLs and patients' backgrounds and presence of aura were assessed. Results The overall prevalence of RLs and PFO in migraine patients was 54.5% and 43.8%, respectively. The prevalence of RLs and PFO in the MA group were significantly higher than in the MWOA group (RLs, 62.9% vs. 44.0%, p=0.046; PFO, 54.8% vs. 30.0%, p=0.008). There were no marked differences in the prevalence of large, middle and small shunts between MA and MWOA patients. Compared with the MWOA patients, the MA patients were younger (p=0.013) and had early onset age (p=0.013) and increased prevalence of photophobia (p=0.008). Conclusion RLs were found in over half of the Japanese patients with migraine. Our study suggests a possible link between RLs and MA.

Abstract
Pulmonary right-to-left shunting can be encountered using transthoracic contrast echocardiography (TTCE) with agitated saline. Diseases associated with pulmonary shunting on saline TTCE include hereditary hemorrhagic telangiectasia (HHT), hepatopulmonary syndrome, and some congenital heart defects after partial or complete cavopulmonary anastomosis. Furthermore, small pulmonary shunts on saline TTCE are also documented in a proportion of healthy individuals. Pulmonary shunting carries the risk for severe neurologic complications due to paradoxical embolization. In HHT, additional chest computed tomography is recommended in case of any pulmonary shunt detected on saline TTCE, to evaluate the feasibility for transcatheter embolotherapy of pulmonary arteriovenous malformations. Furthermore, antibiotic prophylaxis is advised in case of any pulmonary shunt on saline TTCE to prevent brain abscesses after procedures with risk for bacteremia. The present review provides an overview of important aspects of pulmonary shunting and its detection using saline TTCE. Furthermore, advances in understanding the clinical implications of different pulmonary shunt grades on saline TTCE are described. It appears that small pulmonary shunts on saline TTCE (grade 1) lack any clinical implication, as these shunts cannot be used as a diagnostic criterion for HHT, are not associated with an increased risk for neurologic complications, and represent pulmonary arteriovenous malformations too small for subsequent endovascular treatment. This implies that additional chest computed tomography could be safely withheld in all persons with only small pulmonary shunts on saline TTCE and sets the stage for further discussion about the need for antibiotic prophylaxis in these subjects. Besides further optimization of the current screening algorithm for the detection of pulmonary arteriovenous malformations in HHT, these observations can be of additional clinical importance in other diseases associated with pulmonary shunting and in those healthy individuals with documented small pulmonary shunts on saline TTCE.

Abstract
BACKGROUND Hereditary hemorrhagic telangiectasia (HHT) can be diagnosed according to the four clinical Curaçao criteria, including the presence of pulmonary arteriovenous malformations (PAVMs). In the past few years, transthoracic contrast echocardiography (TTCE) replaced chest high-resolution CT (HRCT) imaging for the screening of PAVMs. The objective of this study was to determine whether the presence of any pulmonary shunt on TTCE can be accepted as a new clinical Curaçao criterion in diagnosing HHT. METHODS Between 2004 and 2012, we included 487 first-degree relatives of known HHT-causing mutation carriers who underwent both TTCE and chest HRCT imaging to screen for PAVMs. A quantitative three-point grading scale was used to differentiate among minimal, moderate, or extensive pulmonary shunt on TTCE (grade 1-3). Genetic testing was performed in all people and considered the gold standard for the diagnosis of HHT. RESULTS Chest HRCT imaging demonstrated PAVMs in 114 of 218 patients (52.3%) with a pulmonary shunt on TTCE. The addition of any pulmonary shunt on TTCE to the current clinical Curaçao criteria increased the number of positive criteria in 92 of 487 individuals (18.9%), which increased the sensitivity in diagnosing HHT from 88% to 94% at the expense of a decreased specificity from 74% to 70%. Accepting only pulmonary shunt grades ≥ 2 on TTCE as a diagnostic criterion for HHT enhanced the number of positive criteria in 30 (6.2%) individuals, which led to an increased sensitivity of 90% with no decrease in specificity (74%). CONCLUSIONS The addition of only pulmonary shunt grades ≥ 2 on TTCE to the current clinical Curaçao criteria increases its sensitivity without affecting specificity in the diagnosis of HHT.
