Brief Summary:
This study evaluates mechanisms of arrhythmogenicity in hypertrophic cardiomyopathy, in comparison to patients with well-understood arrhythmogenic substrate (ischemic cardiomyopathy), as well as to individuals free from arrhythmogenic substrate

Condition or disease Intervention/treatment
Hypertrophic Cardiomyopathy Coronary Artery Disease Other: Observational: Arrhythmogenic Substrate

Layout table for study information
Study Type : Observational
Actual Enrollment : 40 participants
Observational Model: Case-Control
Time Perspective: Cross-Sectional
Official Title: Pilot Observational Case-control Study of the Electrical Heterogeneity in Patients With Hypertrophic Cardiomyopathy and High Arrhythmic Risk
Actual Study Start Date : September 2016
Estimated Primary Completion Date : June 2020
Estimated Study Completion Date : June 2020


Group/Cohort Intervention/treatment
Case: Hypertrophic cardiomyopathy
HCM patients at high risk for ventricular arrhythmia
Other: Observational: Arrhythmogenic Substrate
Control I: Healthy
Healthy Controls
Control II: Post-MI with arrhythmogenic substrate
Ischemic cardiomyopathy patients with documented history of ventricular tachyarrhythmia and left ventricular hypertrophy
Other: Observational: Arrhythmogenic Substrate
Control III: VT/VF-free ischemic cardiomyopathy
Ischemic cardiomyopathy patients without ventricular arrhythmia, as proven by non-inducibility and history of freedom from ventricular tachyarrhythmia during at least one ICD generator life



Primary Outcome Measures :
  1. Non-invasively reconstructed epicardial activation map [ Time Frame: within one day ]
