Ventricular arrhythmias (VAs) are frequently associated with structural heart diseases (SHD) such as myocardial infarction, myocarditis, and non-ischemic cardiomyopathies. Myocardial fibrotic tissue plays a central role in the genesis and the maintenance of re-entrant VAs associated with post-myocarditis sequelae and… Read more about this study

About this study

Official title: Image-Based Prediction of Ventricular Tachycardia Events in Post-Myocarditis Patients: an International Multicenter Case-control Study

Ventricular arrhythmias (VAs) are frequently associated with structural heart diseases (SHD) such as myocardial infarction, myocarditis, and non-ischemic cardiomyopathies. Myocardial fibrotic tissue plays a central role in the genesis and the maintenance of re-entrant VAs associated with post-myocarditis sequelae and late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) has proven to be a useful tool for the non-invasive characterization of the scarred tissue and the underlying arrhythmogenic substrate. Moreover, a post-processing imaging platform named ADAS 3D LV (ADAS3D Medical SL, Barcelona, Spain) allows to analyze the CMR-derived data and to characterize the scar architecture, differentiating between dense (scar core zone) and more diffuse (border zone [BZ]) fibrosis, and identifying the BZ channels (BZCs) that are strands of healthy myocardial tissue within zones of unexcitable tissue and connect areas of normal myocardium. It was described that BZCs could serve as slow-conducting reentrant pathways and are critical to entail VA in ischemic and non-ischemic heart disease. However, the pathophysiological role and the correlation between scar architecture and VAs in post-myocarditis patients is yet to be defined.

To date, the standard-of-care evaluation for primary prevention implantable cardioverter-defibrillator (ICD) therapy is LVEF-based, leading to the fact that the contemporary rate of appropriated therapies is very low. Moreover, events may also occur in patients with normal to moderately depressed LVEF, which is particularly relevant, as it constitutes the most prevalent population of patients exposed to an increased risk of VAs. Multiple studies reported that LGE at CMR is a strong and specific predictor of VT occurrence and sudden death in post-myocarditis patients. There were reported cases in which even after the normalization of LVEF, the extension of LGE, the scar architecture, and the presence of BZCs at cMR analysis are determinants of the arrhythmic risk in post-myocarditis patients.

The Investigators sought to evaluate the usefulness of CMR-derived scar architecture analysis to predict the occurrence of VT events in an international, multicenter, case-control study on unselected post-myocarditis patients without previous arrhythmia evidence. Aim of the study is also to assess the net reclassification improvement (NRI) for the indication of primary prevention ICD implantation using CMR data and post-processing data as compared to LVEF-based indication

Research hypothesis

The composite outcome is:

  • sudden cardiac death, sustained VT, syncopal VT or appropriate ICD therapy (ATP and/or shock) in ICD carriers in primary prevention, or
  • sudden cardiac death, sustained VT, syncopal VT detected by any diagnostic test (i.e., 24 h Holter monitoring, prolonged Holter monitoring, urgency ECG etc.) in no ICD-carriers.

Our research hypothesis is that the composite outcome will be higher in those patients with greater scar mass and BZC mass.

Primary objective To analyze the composite outcome of sudden cardiac death or sustained ventricular tachycardia (either treated by an ICD or documented by any diagnostic method) in post-myocarditis patients with no previous arrhythmia evidence, according to their risk classification by means of BZC mass.

Secondary objectives

To analyze the relationship between the primary outcome and other variables:

  • LVEF
  • Scar mass
  • BZ mass
  • Core mass
  • Presence and number of tissue channels within the scar, as detected by cardiac CT
  • Age
  • Time since myocarditis

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of patients presenting one of sudden cardiac death, sustained ventricular arrhythmia, or defibrillator therapy.

    The primary endpoint will be the clinical composite of sudden cardiac death or any sustained ventricular arrhythmia.

    The endpoint will be retrospectively correlated with the cMR-derived findings.

    Measured: 2 years
