An Interdisciplinary Approach to Biobanking in Cardiac Surgery: Protocol of a Prospective, Single-Center Research Project Involving Longitudinal Biobanking

Cross-sectional and longitudinal profiling of full sets of nucleic acids, peptides, or proteins as well as metabolites expressed in biospecimens acquired via a cardiovascular disease-oriented biobank may aid in the elucidation of the disease pathways and mechanisms underlying individual cardiovascular diseases, such as degenerative valvular heart disease. This may promote the development of novel and effective, personalized diagnostic and therapeutic strategies to efficiently reduce cardiovascular mortality and morbidity as well as its health and economic burden. This brief report aims to describe the unique, standardized, interdisciplinary, and interprofessional approach to cross-sectional and longitudinal cardiovascular biobanking and databasing at the University Hospital Augsburg. Moreover, we present the study protocol of a specific, well-defined, prospective, single-center research project involving cross-sectional and longitudinal cardiovascular biobanking. The aim of this project is to gain a better insight into the molecular mechanisms underlying aortic valve disease-induced cardiomyopathy and the long-term effect of surgical correction of the aortic valve pathology on the left ventricular myocardial molecule profile.
