Venoarterial Extracorporeal Membrane Oxygenation for Life-Threatening Complications of Percutaneous Coronary and Structural Heart Interventions

Percutaneous coronary or structural heart interventions may lead to complications, such as perforation and acute vessel closure that may in turn lead to cardiac arrest or cardiogenic shock. Moreover, acute coronary syndrome patients presenting with cardiogenic shock can be challenging to treat due to hemodynamic instability. In such cases, venoarterial extracorporeal membrane oxygenation (V-A ECMO) can provide hemodynamic stabilization and oxygenation allowing successful treatment of the complication or culprit lesion in acute coronary syndrome patients. We present 3 cases illustrating successful emergent use of V-A ECMO in the cardiac catheterization laboratory in the setting of acute left main dissection during a chronic total occlusion intervention, cardiogenic shock in the setting of non-ST segment elevation myocardial infarction and multivessel coronary artery disease, and aortic annular rupture during transcatheter aortic valve replacement.
