Left atrial appendage cannulation for left ventricular unloading in a patient with ventricular thrombus on extracorporeal life support.

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.

Background: Acute myocardial infarction complicated by cardiogenic shock (AMICS) is frequently preceded by out-of-hospital cardiac arrest (OHCA), with risk of anoxic brain injury. Neuron-specific enolase (NSE) is central to neuroprognostication; however, concomitant hemolysis can increase NSE independent of neuronal injury due to the presence of NSE in erythrocytes. This consideration is critical in AMICS patients treated with a microaxial flow pump (Impella, Abiomed), where hemolysis is frequent.

Objective: Right ventricular failure is a leading cause of mortality among patients with various etiologies of cardiogenic shock. This case series outlines an innovative approach to directly unloading the right ventricle with the Impella LD or 5.5 without crossing the tricuspid valve in cases requiring tricuspid valve repair or replacement.

Aortic coarctation represents up to 7% of congenital heart diseases and is associated with hypertension and coronary artery disease, which continues to be the leading cause of death even after successful surgical repair. However, there is limited knowledge of managing both conditions, especially in the setting of an acute coronary syndrome. We herein present the case of a 53-year-old man with a history of hypertension who initially presented with an ST-elevation myocardial infarction successfully treated with thrombolysis and hemodynamic compromise.
