A 62-year-old man had been given a diagnosis of atrial septal defect（ASD）20 years previously, but the condition was left untreated. A heart murmur was detected on a routine health examination, so he visited our institution where a diagnosis of type II ASD and moderate tricuspid regurgitation was given. Cardiac catheterization revealed a pulmonary to systemic flow ratio（Qp/Qs）of 2.9, pulmonary vascular resistance of 3.1 units, and systolic pulmonary artery pressure of 90mmHg. The patient underwent open surgery consisting of a patch closure of the ASD, and tricuspid annuloplasty. His pulmonary arterial pressure rose and his blood pressure dropped, and left cardiac failure developed on postoperative day（POD）2. The administration of catecholamines and a phosphodiesterase（PDE）III inhibitor failed to correct the left cardiac failure. We performed intra-aortic balloon pumping（IABP）immediately, and his hemodynamic condition stabilized. The IABP catheter was removed on POD 10. The postoperative development of circulatory failure suggested that it was almost too late for surgery for ASD. It has been believed that surgery for ASD is relatively safe. However, it seems that, the considering the possible occurrence of postoperative cardiac failure in elderly patients with accompanying pulmonary hypertension, careful postoperative management is necessary.
