Abstract 11257: Physiologic Quantification of the Diastolic Pressure Difference Re-classifies Pulmonary Hypertension in Patients With Advanced Heart Failure

Introduction: Assessment of pulmonary hypertension (PH) by right heart catheterization remains important in the evaluation of advanced heart failure (HF) patients being considered for cardiac transplant. Delineating ‘isolated’ post-capillary PH (Ipc-PH) and ‘combined’ pre- and post-capillary PH (Cpc-PH) remains a challenge in hemodynamic assessment, as the usual practice of calculating the diastolic pressure difference (DPD) has limitations...
