The US Food and Drug Administration (FDA) issued an emergency use authorization for use of the Impella RP heart pump system in COVID-19 patients with right heart failure or decompensation, Abiomed announced today.
“Based on extrapolation of data from the approved indication and reported clinical experience, FDA has concluded that the Impella RP may be effective at providing temporary right ventricular support for the treatment of acute right heart failure or decompensation caused by COVID-19 complications, including PE [pulmonary embolism],” the letter notes.
It cites, for example, use of the temporary heart pump in a 59-year-old woman suffering from COVID-19 who went into right ventricular failure and became hypotensive after an acute PE was removed. After placement of the device, the patient experienced a “dramatic and immediate” improvement in arterial pressure and the device was removed on the fifth day, according to Amir Kaki, MD, and Ted Schreiber, MD, Ascension St. John Hospital, Detroit, whose review of the case has been posted online.
“Acute pulmonary embolism is clearly being recognized as a life-threatening manifestation of COVID-19. Impella RP is an important tool to help cardiologists save lives during this pandemic,” Kaki said in the letter.
“As we have demonstrated in our series of patients, early recognition of right ventricular dysfunction and early placement of the Impella RP for patients who are hypotensive can be life-saving.”
Other data cited in support of the Impella RP emergency use authorization (EUA) include a 2019 series of hemodynamically unstable patients with PE in Japan and a 2019 case report of a 47-year-old man with right ventricular failure, profound shock, and a massive PE.
The FDA granted premarket approval of the Impella RP system in 2017 to provide temporary right ventricular support for up to 14 days in patients with a body surface area of at least 1.5 m2 who develop acute right heart failure or decompensation following left ventricular assist device implantation, myocardial infarction, heart transplant, or open-heart surgery.
The EUA indication for the Impella RP system is to provide temporary right ventricular support for up to 14 days in critical care patients with a body surface area of at least 1.5 m2 for the treatment of acute right heart failure or decompensation caused by complications related to COVID-19, including PE.
The Impella RP is authorized only for emergency use under the EUA and only for the duration of the circumstances justifying use of EUAs, the letter notes.
Last year, concerns were raised about off-indication use after interim results from a postapproval study suggested a higher risk for death than seen in premarket studies treated with the temporary heart pump.
