In October, at TCT Connect, more than 20 presentations and abstracts were presented validating the benefits of a more complete revascularization with Impella heart pumps in high-risk percutaneous coronary intervention (PCI) patients and the value of Impella protocol-based treatment for survival and native heart recovery in cardiogenic shock and right heart failure patients. Key data presented includes:
New PROTECT III study data demonstrates reduced rates of MACCE (composite of death, stroke, myocardial infarction and repeat procedures) compared to the Protect II dataset (15% vs. 21.9%, p=0.035).
The Restore EF Study demonstrates the use of contemporary best practices with Impella-supported high-risk PCI enables a more complete revascularization and is associated with significant improvement of left ventricular ejection fraction (45% relative improvement), heart failure symptoms (80% reduction in NYHA Class III, IV), and anginal symptoms at follow up (99% reduction in CCS Angina Class III, IV).
Data from the RECOVER III post-market approval (PMA) study of AMI cardiogenic shock (AMICS) patients was presented in two studies. The first study, presented by Hemindermeet Singh, MD, of Ascension St. John Hospital, found an 18% relative improvement in overall survival in the recent cohort (2017 - 2019) versus a pre-PMA cohort (2008 - 2014), indicating increased adoption of the cardiogenic shock best practices, including placing Impella pre-PCI has led to an improvement in overall survival rates. The second study, presented by Tayyab Shah, MD, of the Yale School of Medicine, found that placing Impella pre-PCI in AMICS patients is associated with higher survival, particularly in women, as compared to post-PCI (74% relative survival benefit).
Two Impella RP studies find that early identification of right heart failure and early use of Impella RP is associated with significantly higher survival rates. The ongoing PMA post-approval study, RECOVER RIGHT, presented by Mark Anderson, MD, found patients who received Impella RP support within 48 hours of cardiogenic shock onset had a significantly higher survival rate than those who received delayed right-heart support (73% vs. 14%, p
