What would be a reasonable means of mechanical circulatory support as a bridge to AVR for patients with severe aortic regurgitation complicated by cardiogenic shock?

Options are limited when dealing with severe aortic regurgitation. LAVA-ECMO should be considered to provide needed support. This can reduce the increased left-sided filling pressures and urgent surgery is warranted. Tandem heart can also be considered to help provide needed support without increased left-sided filling pressures.
