Although intra-aortic balloon pump- ing (IABP) is widely used in patients with CS, application of IABP in patients with TC sometimes worsens haemodynamics when it is compli- cated by a left ventricular outflow tract obstruction (LVOTO). Here, we report on haemodynamic deterioration caused by the introduction of an IABP, which also increased the pressure gradient be- tween the aorta and left ventricle (LV), when it was applied in a patient with TC and LVOTO. Twelve-lead electrocardiography—an electro- cardiogram showed ST-segment elevation from leads II, III, aVf, and V2–V6 (Panel A). Coronary angiography (CAG), left ventriculography (LVG), and simultaneous dual-catheter pressure waveforms in the aorta and LV—CAG and LVG revealed no significant obstructive coron- ary artery disease and left ventricular apical ballooning (Panel B). Simultaneous dual-catheter pressure waveforms showed a pressure gradient (70 mmHg) between the aorta and LV. Effect of IABP on haemodynamics—an IABP supports a markedly worsened pressure gradient (70!120 mmHg) between the aorta and LV and decreased systemic mean blood pressure (94!63 mmHg) (Panel C). Haemodynamic effect of propranolol—after interrupting IABP, propranolol (2 mg) was administered intravenously, which improved the pressure gradient (70!30 mmHg) and systemic mean blood pressure (94!116 mmHg) (Panel D).
