Right ventriculoarterial coupling in patients with pulmonary arterial hypertension
| Diagnosis | Emax | Ea | Emax/Ea | Reference |
|---|---|---|---|---|
| IPAH | Increase | Increase | Decrease | 16 |
| CCTGA | Increase | Increase | Decrease | 17 |
| IPAH | Increase | Increase | No change | 18 |
| SSc-PAH | Increase | Increase | Decrease | 18 |
Note
Emax: maximum right ventricular elastance; Ea: pulmonary arterial elastance; IPAH: idiopathic pulmonary arterial hypertension; CCTGA: congenitally corrected transposition of the great arteries (systemic right ventricle); SSc-PAH: systemic sclerosis–associated pulmonary arterial hypertension.
