Key result
Impella RP successfully bridges post-operative acute right heart failure to clinical and echocardiographic recovery.
Why the study?
Post-operative right coronary artery occlusion can cause acute right heart failure despite coronary artery bypass grafting, requiring effective mechanical support strategies.

May support Impella RP in select post-operative right heart failure; leaves open need for prospective trials before wider use.
Post-operative right coronary artery occlusion is a serious complication that demands acute coronary revascularization to prevent myocardial infarction. We present two cases with acute right coronary artery obstruction caused by (1) transfemoral aortic valve implantation and (2) acute type A aortic dissection. Although coronary artery bypass grafting was performed intraoperatively, right heart failure was observed in both cases. The Impella RP® device offers temporary right ventricular mechanical support; wherefore, we decided to deploy it in both patients. The devices were uneventfully and successfully implanted to bridge for recovery of the right heart. We report the perioperative course of the patients as well as their condition at 1 year follow-up.

Santer et al. (2020) conducted a case report in Acute Right Heart Failure (n=2). Impella RP was evaluated on Hemodynamic stabilization and recovery of right heart function. The Impella RP device successfully provided temporary right ventricular mechanical support, bridging two patients with post-operative acute right heart failure to clinical and echocardiographic recovery.
