%X Background. The “weekend effect” has been associated with worse clinical outcomes. Our aim was to compare off-hours vs. regular-hours peripheral venoarterial extracorporeal membrane oxygenation (VA-ECMO) in cardiogenic shock patients. Methods. We analyzed in-hospital and 90-day mortality among 147 consecutive patients treated with percutaneous VA-ECMO for medical reasons between July 1, 2013, and September 30, 2022, during regular-hours (weekdays 8:00 a.m.–10:00 p.m.) and off-hours (weekdays 10:01 p.m.–7:59 a.m., weekends, and holidays). Results. The median patient age was 56 years (interquartile range [IQR] 49–64 years) and 112 (72.6%) were men. The median lactate level was 9.6 mmol/L (IQR 6.2–14.8 mmol/L) and 136 patients (92.5%) had a Society for Cardiovascular Angiography and Interventions (SCAI) stage D or E. Cannulation was performed off-hours in 67 patients (45.6%). In-hospital mortality was similar in off-hours and regular hours (55.2% vs. 56.3%, p = 0.901), as was the 90-day mortality (58.2% vs. 57.5%, p = 0.963), length of hospital stay (31 days [IQR 16–65.8 days] vs. 32 days [IQR 18–63 days], p = 0.979), and VA-ECMO related complications (77.6% vs. 70.0%, p = 0.305). Conclusions. Off-hours and regular-hours percutaneous VA-ECMO implantation in cardiogenic shock of medical cause have similar results. Our results support well-designed 24/7 VA-ECMO implantation programs for cardiogenic shock patients.
