- hepatomegaly
- +5 more criteria
You may not qualify if:
- Evidence of primary hypertrophic or restrictive cardiomyopathy or systemic illness known to be associated with infiltrative heart disease
- Known cause of right heart failure not related to left ventricular dysfunction
- Pericardial constriction
