Rescue balloon pulmonary angioplasty for refractory heart failure in chronic thromboembolic pulmonary hypertension complicated with takotsubo cardiomyopathy

Balloon pulmonary angioplasty (BPA) seems promising for treating critically ill patients with chronic thromboembolic pulmonary hypertension (CTEPH) because of its less invasive and stepwise nature. However, there are only a few reports on rescue BPA. Herein, we present a case of CTEPH and takotsubo cardiomyopathy in an 82-year-old female. Despite treatment with catecholamines and intra-aortic balloon pumping, low output syndrome due to right heart failure with CTEPH and left heart failure with takotsubo cardiomyopathy did not improve. Therefore, rescue BPA for CTEPH was performed; this immediately improved the patient's hemodynamics.

Learning objective: Rescue balloon pulmonary angioplasty (BPA) is an option for critically ill patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH) that requires immediate improvement of hemodynamics. BPA strategy initially aimed at partial improvement of pulmonary circulation would be useful in treating CTEPH complicated by refractory right and left heart failure due to coexisting left-sided heart disease.
