Key inclusion & exclusion criteria

Inclusion Criteria:

- All consecutive patients referred for organic MR and/or AR at least moderate to severe
according to the ESC guidelines criteria4 will be eligible. The moderate to severe
criteria will defined by echocardiography as followed:

(RV) >45mL

- AR: an EOA >20mm2 and/or a RV >45mL

Exclusion Criteria:

- Age < 18 years

- Pregnancy

- Impossibility to maintain a decubitus position

- Arrhythmia that do not allow an ECG synchronization during MRI

- Hemodynamic instability

- Indication of urgent surgery

- Known coronary artery disease

- Severe arterial hypertension

- Cardiomyopathy

- Claustrophobia

- Gadolinium intolerance

- Implantable medical devices that do allow to perform MRI

- Severe renal insufficiency with clearance <35 mL/min

- Vulnerable patients

- Acute infective endocarditis

- Aortic dissection

- Moderate or severe mitral stenosis (mitral area <1.5cm2/m2)

- Moderate or severe aortic stenosis (aortic area <0.8cm2/m2, or Vmax>3m/s, or mean
gradient>30mmHg)

- Previous cardiac surgery
