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:
- MR: an effective regurgitant orifice area (EOA) >30mm2 and/or a regurgitant volume
(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
