Biobank for Arrhythmia and Conduction Disorders: TowArd Pathophysiology Based Treatment

Study Overview
=================
Brief Summary
-----------------
The 'ADAPT' Biobank is a collection of body material and data from patients with or at risk of cardiac arrhythmias who underwent or will undergo (non-) invasive treatment for this disease. Its main objective is to obtain a comprehensive collection of patient information and material to facilitate research and gain better insight into the complex pathophysiology of the different arrhythmias, the multifactorial process, the heterogeneity in clinical presentation, and prognosis. Bodily material is used for biochemical marker assessments, histological and molecular analyses for research in cardiac arrhythmias.

Detailed Description
-----------------
The pathophysiological process of many cardiac arrhythmias is complex because of its multifactorial character. Despite extensive research that has already been performed in the field of electrophysiology the exact pathophysiological process of the different arrhythmias remains incompletely understood. The ability to identify subgroups of patients within a population with the same type of arrhythmia that can benefit from a specific treatment strategy might provide more individualized therapeutic opportunities, improve prognostication or provide preventive opportunities in patient with cardiac arrhythmias. Biobanks can make a valuable contribution to the development of diagnostic, preventive and therapeutic methods. More insights into the correlations between genes, environmental factors and susceptibility to illness may be of great value. The 'ADAPT' Biobank has been designed to establish a systematic and qualitative collection of bodily materials for future research in the cardiovascular field. The Biobank includes bodily material of patients with cardiac arrhythmias undergoing (non-) invasive treatment or control patients undergoing cardiothoracic surgery. Clinical data related to the cardiac arrhythmic disease is recorded. The data and samples will be linked to the participants' medical records to allow longitudinal follow-up.
