Background. 

Temporary extracorporeal membrane oxygenation (ECMO) support for high-risk percutaneous coronary intervention (PCI) has been described in select patients, and data are limited on the CardioHELP device (Maquet). The objective of this study was to assess clinical outcomes in patients undergoing elective, high-risk PCI with CardioHELP support. 

Methods. Fifteen consecutive patients receiving the CardioHELP device for elective, high-risk PCI treated at 2 medical centers were included. Patients with cardiogenic shock, cardiac arrest, or non-PCI indications for ECMO were excluded. Baseline demographics, angiographic variables, procedure-related variables, and in-hospital events were collected. 

Results. 

Mean age was 71 ± 11 years, 73% were male, mean ejection fraction (EF) was 29 ± 13%, 10 patients (67%) had an EF <30%, and mean SYNTAX I score was 32 ± 11. Multivessel coronary artery disease was present in 14 patients (93%) and unprotected left main coronary artery disease was present in 4 patients (27%). PCI was successful in all patients. In-hospital mortality occurred in 3 patients (20%), 7 patients (47%) received a blood transfusion, and there were no major vascular complications.

 Conclusion. 

Temporary use of the CardioHELP device for high-risk PCI is associated with acceptable short-term outcome and may be a new option for patients with complex coronary artery disease and left ventricular dysfunction.
