We describe a technique for insertion of the Impella RP device that does not require fluoroscopy. Venous cannulation was performed via the superior vena cava and femoral vein percutaneously. After right atriotomy, the Impella RP is percutaneously inserted and advanced to the right atrium under transesophageal echocardiography guidance. Next, via a longitudinal 2 cm incision in the main pulmonary artery (PA), a large C-shaped clamp is advanced retrograde through the pulmonic and tricuspid valves into the right atrium. The pigtail portion is grasped, pulled through to the main PA, and the device is positioned in the PA under direct vision.

Background: Consensus regarding on-support evaluation and weaning concepts from Impella 5.5 support is scarce. The derived left ventricular end-diastolic pressure (dLVEDP), estimated by device algorithms, is a rarely reported tool for monitoring the weaning process.

Background: There is a lack of data on the role of chronic kidney disease (CKD) in patients who received percutaneous left ventricular assist devices (pLVAD) as mechanical circulatory support (MCS) as an adjunct treatment for cardiogenic shock (CS) management.
Methods: Using National Inpatient Sample (2016-19), we extracted CS patients receiving pLVAD and divided them into CKD and non-CKD cohorts. Multivariate regression analysis was used for adjusted odds ratios for outcomes before and after entropy balancing (EB) and predictive margins for the probability of all-cause in-hospital mortality (ACM).

Background: Impella 5.5 ventricular assist device (VAD) insertion is typically done via the axillary artery or directly through the aorta; however, an axillary artery must be ≥6 mm in diameter, which excludes many pediatric patients who do not meet this criterion. The innominate artery is a larger vessel that can better accommodate the Impella VAD in pediatric patients.

Background: Left ventricular unloading is needed in patients on extracorporeal life support (ECLS) with severely impaired left ventricular contractility to avoid stasis and pulmonary congestion, and to promote LV recovery. The presence of thrombi in the LV precludes the use of conventional active unloading methods such as transaortic microaxial pumps or apical LV vents. We describe placement of a vent cannula via the left atrial appendage (LAA) as a useful bailout option.

Purpose Of Review: This article discusses a tailored approach to managing cardiogenic shock and temporary mechanical circulatory support (tMCS). We also outline specific mobilization strategies for patients with different tMCS devices and configurations, which can be enabled by this tailored approach to cardiogenic shock management.
Recent Findings: Safe and effective mobilization of patients with cardiogenic shock receiving tMCS can be accomplished.
