OBSERVATIONAL
Summary
This project aims to validate sex-specific biologic signatures associated with aortic valve disease developed in a large multicenter CMR registry, using unsupervised phenomapping. The aim to use standard and advanced CMR techniques (MRF, DTI, chemical exchange transfer, and radiomics analysis) is to determine advanced CMR predictors of reverse remodeling following aortic valve surgery and develop sex-specific thresholds for risk. Infrastructure developed by this study will enable development of an innovative, scalable, sex-specific precision medicine cardiovascular imaging pipeline to determine overall risk and treatment response.
Eligibility
Inclusion Criteria2
- Age 18-90 years of age

Exclusion Criteria8
- Acute traumatic cardiac injury
- Aortic dissection or aortic root rupture
- Congenital heart diseases such as patent ductus arteriosus, coarctation of aorta, ASD and VSD
- Presence of A-V fistula or intracardiac shunts

- Patients with any MR-incompatible implant, including cardiac pacemakers or defibrillators, or older types of cerebral aneurysm clips.
- Patients who weigh more than 440 lbs. or have a very wide waist circumference.
- Patients with claustrophobia may have difficulty tolerating the exam.
