Right ventricular dysfunction in cardiogenic shock on temporary mechanical circulatory support.

ABSTRACT:

Aims

Right ventricular dysfunction (RVD) is common in cardiogenic shock (CS) due to left ventricular failure and is associated with increased mortality, but its impact in patients requiring temporary mechanical circulatory support (tMCS) remains unclear. We explored RVD and its association with clinical outcomes in CS patients under tMCS.

Methods and results

Individuals with CS from the SWISS Circulatory Support Registry (NCT04117230) were included. RVD was defined by ≥1 of the following parameters: tricuspid annular plane systolic excursion (TAPSE) < 14 mm, TAPSE/systolic pulmonary artery pressure (sPAP) < 0.34, right atrial pressure (RAP) > 15 mmHg, RAP/pulmonary capillary wedge pressure >0.63 or pulmonary artery pulsatility index (PAPi) < 1.85. The primary endpoint was 6-
