Filter by:Each year world-wide, 2.5 million fetuses die unexpectedly in the last half of pregnancy, 25,000 in the United States, making fetal demise ten-times more common than Sudden Infant Death Syndrome. This study will apply a novel type of non-invasive monitoring, called fetal magnetocardiography (fMCG) used thus far to successfully evaluate fetal arrhythmias, in order to discover potential hidden electrophysiologic abnormalities that could lead to fetal demise in five high-risk pregnancy conditions associated with fetal demise.
To determine the values and limitations of ECGI in guiding ablation and risk stratification in patients with BrS and Early Repolarization.
Brugada syndrome has been described as the association of a right bundle block with ST segment elevation on the V1 to V3 electrocardiogram in patients with a structurally normal heart. The rhythmic risk is thus difficult to evaluate in asymptomatic patients in whom the rate of events is estimated at 0.2 to 1.4% of events per year. In addition, the predictive value of ventricular pacing remains controversial; There is therefore currently no review to effectively assess rhythmic risk in patients with Brugada type I syndrome. Investigators aimed to show a difference in pulmonary infundibulum voltage mapping in symptomatic and asymptomatic patients with Brugada type 1 syndrome with a comparable ECG. The mapping of the pulmonary infundibulum will be performed during electrophysiological exploration. Only the catheter used differs from the usual procedure.
The study purpose is to evaluate the morphological, functional and electrophysiological characteristics of the right ventricle before and after ajmaline in patients diagnosed with Brugada syndrome as well as to correlate CMR findings and substrate size.
In this study the investigators analyse echocardiographic images before and during Ajmaline test. The purpose is to know if any echocardiographic modifications are present during either negative or positive Ajmaline testing.
Although for many years the Brugada syndrome has been labelled as a purely electrical disease in the structurally normal heart, the evolution of imaging techniques has enabled the discovery of subtle morphofunctional alterations in some of the Brugada syndrome patients. We will use new echocardiographic techniques to assess cardiac function in these patients and new parameters will be evaluated for their prognostic value as risk stratificators.
Whether a mapping algorithm "Ripple-mapping" is able to rapidly identify the areas of long-duration multicomponent electrograms which constitute the targets for ablation for an automated strategy remains to be assessed.
A total of 150 patients will be randomized to perform catheter ablation or not in a 2:1 fashion in selected patients with Brugada-related symptoms (Ablation+ICD arm 105 patients vs ICD only 45 patients).
Patients with cardiac channelopathies needing restorative dental treatment will be included in two sessions of the study, using local dental anesthetic: lidocaine 2% with epinephrine and lidocaine 2% without vasoconstrictor. The safety of the use of two cartridges (3.6 mL) will be evaluated. The patients will be their own control and will be assessed by Holter monitoring for 28 hours, blood pressure measurement and anxiety measuring.
The purpose is to increase the understanding of the characteristics, circumstances, medical histories and pathologies of children from ages 11 months through 18 years who have died suddenly and unexpectedly, and in some instances, without explanation. The SUDC Registry and Research Collaborative will analyze cases of sudden unexpected deaths in these children to understand risk factors and causes, and develop preventative measures.
