Abstract
Background Cardiac biomarker release is ubiquitous following surgical and transcatheter aortic valve replacement (SAVR and TAVR), preventing accurate discrimination between release due to focal myocardial infarction (MI) and global myocardial injury. Cardiovascular magnetic resonance (CMR) late gadolinium enhancement imaging (LGE) is the most sensitive imaging method to detect post-procedural new MI. Our study aimed to compare rates of new MI using CMR LGE before and 6m after TAVR and SAVR.
Highlights
Cardiac biomarker release is ubiquitous following surgical and transcatheter aortic valve replacement (SAVR and TAVR), preventing accurate discrimination between release due to focal myocardial infarction (MI) and global myocardial injury
Areas of late gadolinium enhancement imaging (LGE) were quantified with computer-assisted planimetry (2SD; cmr42,Circle CVI)
Presence of new LGE was determined by direct comparison of pre and post-procedure scans
