Early Detection of Pulmonary Arterial Hypertension Using Cardiac Magnetic Resonance Imaging

Completed
Conditions
Pulmonary Hypertension
Pulmonary Arterial Hypertension
Registration Number
NCT01451255
Lead Sponsor
Mayo Clinic
Brief Summary

Cardiac magnetic resonance imaging has emerged as a potential valuable test for the early detection of Pulmonary Arterial Hypertension. A number of reports have provided some preliminary evidence that Pulmonary Artery (PA) stiffness may be accurately detected by imaging of the pulmonary artery in order to measure PA stiffness. In addition, cardiac MRI could play provide early and effective treatment for Pulmonary Arterial Hypertension (PAH).

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)
  • 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
