The ProtekDuo dual-lumen cannula for temporary acute mechanical circulatory support in right heart failure: A systematic review

Introduction Acute right ventricular failure (aRVF) is associated with high mortality and morbidity. Mechanical circulatory support (MCS) may be considered as an advanced treatment option. The ProtekDuo is a cannula that can be used to provide acute right ventricular support as part of a temporary percutaneous (tp) right ventricular assist device (RVAD) system. The primary objective of this systematic review is to describe patient survival and complications when the ProtekDuo cannula was used as part of an tpRVAD system. Methods MEDLINE, Embase, and Scopus were searched from database inception to August 26, 2022. Reference sections of studies were reviewed to screen for database omissions. Results Seven studies with 127 patients were eligible for inclusion. The studies included patients with aRVF from a variety of causes. Mean duration of support was between 10 and 58 days in five studies. Patient survival to discharge was between 60% and 85.2% in two studies. Four authors reported 30-day survival between 60% and 85.2%. Devicerelated and non-device related complications were low. Conclusions Patients treated with RVAD using the ProtekDuo cannula have comparable survival rates and complications to other tpRVAD systems. Several advantages exist compared to other RVAD systems.
