- Cardiac MRI can differentiate between classical idiopathic pulmonary arterial hypertension (iPAH), iPAH with a lung phenotype, and group 3 pulmonary hypertension (PH).
- The study included 34 patients: 11 with classical iPAH, 11 with iPAH and a lung phenotype, and 12 with group 3 PH.
- T1 mapping values in the interventricular septum and inferior ventricular insertion point were significantly higher in classical iPAH compared to iPAH with a lung phenotype.
- No significant differences were observed in ventricular functions and flow rates among the groups.
- Cardiac MRI with T1 mapping effectively discriminates between classical iPAH and iPAH with a lung phenotype, revealing divergent patterns that may explain different treatment responses and prognoses.
