Key result
Underrecognized RV-predominant heart failure shock requires specialized pharmacologic and device-based ICU management.
Why the study?
Right ventricular-predominant heart failure causing shock is less well recognized compared to cardiogenic shock from left ventricular failure.
This review summarizes the epidemiology, mechanisms, and management strategies for right ventricular-predominant heart failure and shock in the cardiac ICU.
Alerts clinicians to consider RV-specific ICU strategies in shock; leaves open prospective validation of management approaches.
Cardiogenic shock from left ventricular failure is a common presentation in the intensive care unit. In contrast, right ventricular (RV)-predominant heart failure (HF) causing shock is less well recognized. We review the epidemiology and mechanisms of RV-predominant HF and discuss pharmacologic and device-based approaches for the management of this challenging clinical problem.
