2017年7月18日 · The Impella RP and the TandemHeart RVAD (TH-RVAD) displace blood from the RA to PA, thereby directly bypassing the RV. In contrast, VA-ECMO displaces and oxygenates blood from the RA to the femoral artery, thereby indirectly bypassing the RV.

An Oxy-RVAD (oxygenator in right VAD circuit) is a lifesaving technique in such cases and allows freedom of introducing and removing an oxygenator into the RVAD circuit without opening the chest and competing with LVAD flow.

2023年4月11日 · Oxygenated right ventricular devices (Oxy-RVAD) using a dual-lumen right atrium to pulmonary artery has been used in COVID ARDS with and without right ventricular failure [1, 12 − 14]. Oxygenated RVAD can be used to bypass the failing right ventricle and directly introduce oxygenated blood directly into the pulmonary artery.

Right ventricular assist device with an oxygenator (OxyRVAD) is an extracorporeal membrane oxygenation (ECMO) configuration of RV bypass that also supplements gas exchange. This systematic review summarises the available literature regarding the use of OxyRVAD in the setting of severe lung disease with associated RV failure.

Instead of adding arterial cannulation, he was switched to a novel configuration, a right ventricular assist device with an oxygenator (Oxy- RVAD) using ECMO, with drainage cannulation from the femoral vein and return cannulation to the main pulmonary artery.

2020年4月1日 · We used Oxy-RVAD (RA-PA ECMO) as novel configuration delivered via anterior thoracotomy to treat end-stage IPF patients with RHF. Patients with RHF caused by secondary pulmonary hypertension, who had a bridge to LT, were indicated for Oxy-RVAD placement.

Peripherally cannulated oxyRVAD may provide oxygenation support with right heart support as an alternative to venoarterial extracorporeal membrane oxygenation (ECMO) as a bridge to lung transplantation.

Figure 1 Roadmap to evaluate the oxygenated right ventricular assist device (OxyRVAD) as a viable bridging strategy for refractory hypoxemia and right ventricular (RV) failure. Comparative OxyRVAD studies should consider primary disease, hospital presentation, and bridging strategy to inform indications, outcomes, and patient-device complications.

2021年7月1日 · OxyRVAD stabilized hemodynamic parameters without fatal complications, permitted the discontinuation of sedation, and allowed active rehabilitation in patients with severe right heart failure. OxyRVAD may be a feasible option for …

2014年12月23日 · An Oxy-RVAD (oxygenator in right VAD circuit) is a lifesaving technique in such cases and allows freedom of introducing and removing an oxygenator into the RVAD circuit without opening the chest and competing with LVAD flow.
