Classification of PH and Pointers to Each Subset

Dana Point Clinical Classification		Flags	Suggested Sequences
Group	Name
1.	PAH	Shunts, aberrant pulmonary veins	Dedicated views, flow mapping and MRA
2.	Left heart disease	LV impairment, hypertrophy or wall motion abnormalities, dilated left atrium, valvular disease Pulmonary vein stenosis	LGE and valve lesion quantification Cine SSFP, flow and MRA
3.	Lung diseases and/or hypoxia	Emphysematous or fibrosed lung fields. However compared to high-resolution computed tomography, CMR images lungs poorly
4.	CTEPH	Filling defects in the pulmonary arteries	MRA
5.	Unclear and/or multifactorial mechanisms	Lymphadenopathy Absent spleen	LGE

PAH; Pulmonary arterial hypertension, CTEPH; chronic thromboembolic pulmonary hypertension, MRA; magnetic resonance angiography, LGE; late gadolinium enhancement SSFP: steady state free procession.
