Abstract:
The role of atrioventricular (AV) dyssynchrony as a cause of low Impella device output in cardiogenic shock from acute anterior myocardial infarction (MI) responding to reestablishing AV synchrony has not been previously reported. We present, for the first time, a unique case of AV dyssynchrony causing recurrent hypotension and ventricular fibrillation in such a patient, followed by immediate return to hemodynamic stability after restoring AV synchrony. Our case also highlights the novel use of a Damato multi-polar catheter for coronary sinus pacing to achieve AV synchrony.
