Effect of Atrioventricular Dyssynchrony on Impella Hemodynamics: Mechanism and Its Clinical Implications

The physiologic importance of atrial systole and atrioventricular (AV) synchrony in maintaining cardiac performance is well established. However, the role of AV synchrony in maintaining adequate Impella output has not been fully evaluated. Despite the common belief that AV dyssynchrony does not affe...

description The physiologic importance of atrial systole and atrioventricular (AV) synchrony in maintaining cardiac performance is well established. However, the role of AV synchrony in maintaining adequate Impella output has not been fully evaluated. Despite the common belief that AV dyssynchrony does not affect Impella output, given that Impella is a continuous flow device, recent reports indicate that AV dyssynchrony can lead to low Impella output in patients with cardiogenic shock complicated by complete heart block. Temporary transvenous pacing without establishing AV synchrony may fail to improve Impella hemodynamics; therefore, understanding the mechanism of low Impella output in AV dyssynchrony and promptly restoring AV synchrony may improve Impella output in such cases and lead to better outcomes.
