Key result
Intra-aortic balloon pumping decreased cardiac afterload and exacerbated left ventricular outflow tract obstruction, resulting in cardiogenic shock in a patient with hypertrophic obstructive cardiomyopathy.

Does intra-aortic balloon pumping exacerbate left ventricular outflow tract obstruction and induce cardiogenic shock in patients with hypertrophic obstructive cardiomyopathy?
IABP should be used with extreme caution in patients with HOCM, as its afterload-reducing effects can exacerbate LVOT obstruction and induce cardiogenic shock.
Answers are grounded in this paper and cite their sources.
IABP may worsen LVOT obstruction in obstructive HCM; this case leaves open questions on device safety.

OTA et al. (2023) conducted a case report in Hypertrophic Obstructive Cardiomyopathy (HOCM) (n=1). Intra-aortic balloon pumping (IABP) was evaluated on Cardiogenic shock due to LVOTO. Intra-aortic balloon pumping decreased cardiac afterload and exacerbated left ventricular outflow tract obstruction, resulting in cardiogenic shock in a patient with hypertrophic obstructive cardiomyopathy.
