Arm Intervention/treatment
Experimental: Subjects with unexplained but suspected cardiac dyspnea
Subjects with unexplained but suspected cardiac dyspnea who are being scheduled for right heart catheterization will undergo an exercise cardiac magnetic resonance imaging (eCMR).
Device: Exercise cardiac magnetic resonance imaging
Subjects will exercise on a treadmill and immediately following the completion of the stress protocol, subjects will undergo cardiac magnetic resonance imaging
Other Name: eCMR




Primary Outcome Measures :
  1. Ejection Fraction [ Time Frame: Baseline ]
    Measured using exercise cardiac magnetic resonance imaging (eCMR) reported in percentages

  2. Stroke Volume [ Time Frame: Baseline ]
    Measured using exercise cardiac magnetic resonance imaging (eCMG) reported in mL

  3. Longitudinal Strain Assessment [ Time Frame: Baseline ]
    Measured using exercise cardiac magnetic resonance imaging (eCMG) reported in percentages

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
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
