ABSTRACT
Prevalence of combined pre- and post-capillary (Cpc) pulmonary hypertension (PH) in patients with PH due to left heart disease (PH-LHD) and the long-term impact of left ventricular assist device (LVAD) implantation in patients with Cpc-PH are not fully elucidated. Eighty-nine patients with PH-LHD who underwent LVAD implantation were retrospectively analyzed. Patients were divided into two groups according to their preoperative pulmonary vascular resistance (PVR) and diastolic pressure gradient (DPG) values (Cpc-PH group, PVR >3 wood units [WU], or DPG ≥7 mmHg; isolated postcapillary [Ipc]-PH group, PVR ≤3 WU, and DPG <7 mmHg). There were 50 patients with Cpc-PH (PVR >3 WU [group A, n = 41]; PVR >3 WU and DPG ≥7 mmHg [group B, n = 8]; DPG ≥7 mmHg [group C, n = 1]), and 39 patients with Ipc-PH. Despite a successful LVAD implantation in all participants, 13 and two patients remained in groups A and B, respectively, early after LVAD implantation, whereas two patients each remained in groups A and B 1 year postoperatively. Values of PVR and DPG in the Cpc-PH group returned to normal levels by 3 years postoperatively. Over 50% of patients with PH-LHD had Cpc-PH, and PVR and DPG normalized in all participants within 3 years after LVAD implantation.
