Emergency Resuscitative Endovascular Balloon Occlusion of the Aorta in Out of Hospital Cardiac Arrest...
Out-Of-Hospital Cardiac ArrestCardiac Arrest4 moreThis study will assess the feasibility of performing pre-hospital resuscitative endovascular balloon occlusion of the aorta (REBOA) as an adjunct to conventional Advanced Life Support (ALS) in patients suffering from non-traumatic out of hospital cardiac arrest (OHCA). As well as providing valuable insights into the technical feasibility of performing this procedure as part of a resuscitation attempt, the study will also document the beneficial physiological effects of REBOA in this group of patients.

Role of Endomyocardial Biopsy and Aetiology-based Treatment in Patients With Inflammatory Heart...
MyocarditisVentricular Arrythmia7 moreMyocarditis is a complex inflammatory disease, usually occurring secondary to viral infections, autoimmune processes or toxic agents. Clinical presentations are multiple, including chest-pain, heart failure and a broad spectrum of arrhythmias. In turn, outcome is largely unpredictable, ranging from mild self-limiting disease, to chronic stage and progressive evolution towards dilated cardiomyopathy, to rapid adverse outcome in fulminant forms. Subsequently, myocarditis is often underdiagnosed and undertreated, and optimal diagnostic and therapeutic strategies are still to be defined. This study, both retrospective and prospective, originally single-center and subsequently upgraded to multicenter, aims at answering multiple questions about myocarditis, with special attention to its arrhythmic manifestations. Optimal diagnostic workflow is still to be defined. In fact, although endomyocardial biopsy (EMB) is still the diagnostic gold standard, especially for aetiology identification, it is an invasive technique. Furthermore, it may lack sensitivity because of sampling errors. By converse, modern imaging techniques - cardiac magnetic resonance (CMR) in particular - have been proposed as alternative or complementary diagnostic tool in inflammatory heart disease. Other noninvasive diagnostic techniques, like delayed-enhanced CT (DECT) scan or position emission tomography (PET) scan, are under investigation. Biomarkers to identify myocarditis aetiology, predisposition, prognosis and response to treatment are still to be defined. Arrhythmic myocarditis is largely underdiagnosed and uninvestigated. Importantly, myocarditis presenting with arrhythmias requires specific diagnostic, prognostic and therapeutic considerations. At the group leader hospital, which is an international referral center for ventricular arrhythmias management and ablation, a relevant number of patients with unexplained arrhythmias had myocarditis as underlying aetiology. The experience of a dedicated third-level center is going to be shared with other centers, to considerably improve knowledge and management of arrhythmic myocarditis. The role of CMR, as well as alternative noninvasive imaging techniques, in defining myocarditis healing is a relevant issue. In particular, optimal timing for follow-up diagnostic reassessment is still to be defined, in patients with myocarditis at different inflammatory stages, either with or without aetiology-dependent treatment. Uniformly-designed studies are lacking, to compare myocarditis among different patient subgroups, differing by variables like: clinical presentations, myocarditis stage, associated cardiac or extra-cardiac diseases, aetiology-based treatment, associated arrhythmic manifestations, diagnostic workup, and devices or ablation treatment.
Clinical Validation and Safety of the AC 12L ECG System Against a Standard of Care 12-Lead ECG (AC...
ArrhythmiaAliveCor (www.alivecor.com) has developed an ECG device (KardiaMobile) that interfaces with iOS and Android smartphones and tablets. This ECG consists of a lightweight hardware case with two metal electrodes that can snap onto the back of the phone and a software application. By holding the right finger(s) on the right electrode and the left finger(s) on the left electrode, an electrical circuit is completed and a lead-I, 30 second rhythm strip is created. KardiaMobile and a newer device, KardiaMobile 6L, were approved by FDA for ECG rhythm recording. Recently, AliveCor developed a new device: Kardia 12L to record 12-lead ECGs. However, the data generated from the new device has not yet been validated for accuracy. The specific aim of this study is to evaluate the accuracy and safety of the AC 12L ECG System. The ECGs collected by the AC 12L ECG System will be compared to simultaneous standard- of-care 12-lead ECG, recorded using the GE CardioSoft 12-lead ECG System. The ECGs will be analyzed for accuracy based on statistical difference using root-mean-square error, and cross correlation between the simultaneous 10 second recordings as well as the median beats of all 12 leads.
Confirm Rx Insertable Cardiac Monitor SMART Registry
Cardiac ArrhythmiasSymptoms and Signs1 moreThe purpose of the Confirm Rx SMART Registry is to collect real world data to assess the safety and performance of the Confirm Rx Insertable Cardiac Monitor (ICM) and system over a 12 month period. A sub-set of subjects enrolled in the Confirm Rx SMART Registry will meet the Post Market Clinical Follow-Up (PMCF) requirement for CE mark.
Mayo AVC Registry and Biobank
Arrhythmogenic Right Ventricular CardiomyopathyCardiomyopathies15 moreArrhythmogenic ventricular cardiomyopathy (AVC) is a genetic condition which affects the heart and can lead to heart failure and rhythm problems, of which, sudden cardiac arrest or death is the most tragic and dangerous. Diagnosis and screening of blood-relatives is very difficult as the disease process can be subtle, but sufficient enough, so that the first event is sudden death. The Mayo Clinic AVC Registry is a collaboration between Mayo Clinic, Rochester, USA and Papworth Hospital, Cambridge University Hospitals, Cambridge, UK. The investigators aim to enroll patients with a history of AVC or sudden cardiac death which may be due to AVC, from the US and UK. Family members who are blood-relatives will also be invited, including those who do not have the condition. Data collected include symptoms, ECG, echocardiographic, MRI, Holter, loop recorder, biopsies, exercise stress testing, blood, buccal and saliva samples. Objectives of the study: Discover new genes or altered genes (variants) which cause AVC Identify biomarkers which predict (2a) disease onset, (2b) disease progression, (2c) and the likelihood of arrhythmia (ventricular, supra-ventricular and atrial fibrillation) Correlate genotype with phenotype in confirmed cases of AVC followed longitudinally using clinical, electrocardiographic and imaging data. Characterize desmosomal changes in buccal mucosal cells with genotype and validate with gold-standard endomyocardial biopsies

Atrial FibrillationParoxysmal Atrial Fibrillation5 moreThis clinical study evaluates the safety and efficacy of the treatment with the CoolLoop® cryoablation System (sclerotherapy of muscle tissue of the heart by freezing) in patients with atrial fibrillation (permanent atrial fibrillation excepted) over a follow-up period of 36 months. A further aim of this study is to evaluate the average duration of procedure and fluoroscopy times.
Catheter Ablation of Arrhythmias With High Density Mapping System in the Real World Practice.
Cardiac ArrhythmiasThe CHARISMA study is a non-randomized, multicenter, prospective study in which consecutive patients indicated for arrhythmia will be enrolled. Patients can be treated with any market released catheter for ablation and diagnostic examination. The decision to perform the ablation will be made based on clinical evaluation of the investigators according to their clinical practice. The study does not require specific surgical techniques. The study has been designed to describe the Italian clinical practice in relation to the ablation approach of different kind of arrhythmias. In particular, the investigators will analyze the percentage of acute and long-term success in clinical practice, predictors of arrhythmias recurrence and they will describe the methods for the validation of ablation success, the techniques adopted, and the patient management approaches in the participating centers
