Heart MRI study reveals hidden valve variation in thousands
NCT ID NCT06436573
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 4,000 adults who had a heart MRI to find out how often a small heart valve variation called mitral annular disjunction (MAD) occurs. Researchers wanted to see if MAD is linked to heart valve problems or dangerous heart rhythms. The goal was to better understand this variation, not to test a treatment.

Inclusion Criteria: • Consecutive adult patients (age ≥18 years-old), submitted to Cardiac Magnetic Resonance independently by the clinical suspicions in the first 6 month of 2019 (from January to June 2019) that have signed an Informed Consent authorizing data collection for future retrospective clinical research protocols Exclusion Criteria: • Pediatric patients (age \<18 years-old), cardiac devices (implantable devices), previous mitral valve surgery, lack of LGE images, lack of clinical information about presence of arrhythmias.
