About this trial
This is an interventional diagnostic trial for Shortness of Breath
Eligibility Criteria
Inclusion Criteria:
- Consecutive patients aged ≥18 years years with suspected cardiac dyspnea who are scheduled to undergo right heart catheterization as dictated by a comprehensive examination and echocardiography will be included for enrollment.
Exclusion Criteria:
- Age <18 years
- Pregnancy
- Mechanical ventilation
- Acute or chronic renal failure (creatinine clearance <30 ml/min or requiring renal replacement therapy)
- Inability to perform MRI (i.e. claustrophobia, severe obesity (>150 kg), device incompatible with MRI)
- Inability to exercise
- Significant arrhythmia that precludes adequate ECG-gating for the MRI (i.e. atrial fibrillation with highly variable cycle lengths)
- Prior heart or lung transplantation
- Left ventricular systolic (ejection fraction <50%) or diastolic failure (based on Framingham criteria for heart failure with preserved ejection fraction)
- Significant left-sided valvular disease (≥moderate aortic stenosis, mitral stenosis, aortic regurgitation, mitral regurgitation) or prior valve surgery
Sites / Locations
- Mayo Clinic in Florida
