Expert Consensus on Clinical Application of Implantable Biventricular Assist Devices.

While biventricular assist devices (BiVADs) remain underutilized in Western countries for biventricular heart failure (BHF), their application is expanding in China. This consensus synthesizes international guidelines, medical evidence, and Chinese clinical expertise to establish standardized protocols for BiVAD management. Key recommendations include: (1) Preoperative right heart catheterization and echocardiography for central venous pressure (CVP): pulmonary capillary wedge pressure (PCWP) ratio and pulmonary artery pulsatility index (PAPi) assessment (Class I); (2) BiVAD indication in refractory BHF or high-risk right heart failure post-left ventricular assist device (LVAD) implantation (Class IIa); (3) Right atrial implantation as the preferred surgical approach (Class IIa); (4) Warfarin-based anticoagulation (INR 2.0-2.5) with aspirin, avoiding direct oral anticoagulants (DOACs) (Class III). The guidance addresses critical gaps in patient selection, pump speed titration, and complication management, positioning integrated BiVAD systems as a promising solution for complex BHF.
