Successful β-blocker introduction under intra-aortic balloon pumping and ivabradine in a patient with new-onset dilated cardiomyopathy and pulsus alternans: a case report.

ABSTRACT:

Background

Pulsus alternans has been considered a sign of poor prognosis in patients undergoing treatments for heart failure. However, it may be overlooked in patients with intra-aortic balloon pumps (IABPs). The use of IABP and ivabradine for a β-blocker introduction in a patient with dilated cardiomyopathy (DCM) and pulsus alternans and its consequence have never been reported.

Case summary

In a 16-year-old high school boy with idiopathic DCM [left ventricular end-diastolic diameter (LVDd), 72 mm; left ventricular ejection fraction (LVEF), 18%], the introduction of carvedilol therapy failed, causing cardiogenic shock under inotropes. Therefore, an IABP support was provided, and he was transferred to our hospital. The arterial pressure waveform under IABP demonstrated pulsu
