The patient was a 75-year-old woman,
who had been treated for tuberculosis by artificial right pneumothorax
at the age of 25. Although a cardiac murmur had been pointed
out in her infancy, no treatment had been recommended because
she had no symptoms. Effort dyspnea augmented along with her
aging by degrees. She began to need oxygen therapy at the age
of 75. She had her calcified ductus arteriosus. The systemic
to pulmonary blood flow ratio (Qp/Qs) was 1.89. We diagnosed
that pulmonary dysfunction after artificial right pneumothorax
and pulmonary hypertension caused by persistent ductus arteriosus
were the cause of her symptoms. After median sternotomy we closed
the persistent ductus arteriosus using a patch through the pulmonary
artery under cardiopulmonary bypass. Although she needed respiratory
management with a ventilator for 2 days and oxygen therapy for
4 weeks, she has been doing well afterwards. We think that we
should close persistent ductus arteriosus even in the elderly.
