Management of cardiogenic shock: state-of-the-art.

The management of cardiogenic shock is an ongoing challenge. Despite all efforts and tremendous use of resources, mortality remains high. Whilst reversing the underlying cause, restoring/maintaining organ perfusion and function are cornerstones of management.

Ventriculo-arterial uncoupling with an impella assisted HVAD: The p-D LVAD.

This paper presents the novel use of a temporary percutaneous ventricular assist device (pVAD) in a 51-year-old man with an implanted durable left ventricular assist device (d-LVAD). The pre-existing left ventricular assist device was unable to successfully unload the left ventricle, and the addition of the temporary pVAD achieved successful unloading as well as a decrease in pulmonary artery pressures without compromising the function of the right ventricle allowing safe UNOS listing for orthotopic heart transplantation.

Coronary flow capacity and survival prediction after revascularization: physiological basis and clinical implications.

Background And Aims: Coronary flow capacity (CFC) is associated with an observed 10-year survival probability for individual patients before and after actual revascularization for comparison to virtual hypothetical ideal complete revascularization.

Methods: Stress myocardial perfusion (mL/min/g) and coronary flow reserve (CFR) per pixel were quantified in 6979 coronary artery disease (CAD) subjects using Rb-82 positron emission tomography (PET) for CFC maps of artery-specific size-severity abnormalities expressed as percent left ventricle with prospective follow-up to define survival probability per-decade as fraction of 1.0.

Comparison of survival by vasoactive-inotropic score in patients receiving veno-arterial extracorporeal life support.

After the initiation of veno-arterial extracorporeal membrane oxygenation (V-A ECMO) for hemodynamic support, patients often require vasopressor and inotropic medications to support their blood pressure and cardiac contractility. The vasoactive-inotropic score (VIS) is a standardized calculation of vasopressor and inotrope equivalence, which uses coefficients for each medication to calculate a total value. This study evaluated the association between the 30-day survival of patients receiving V-A ECMO support and the VIS calculated 24 h after ECMO cannulation (VIS24).
